You Are Absolutely Correct.
That's why operating system kernels that are writing by clueful coders validate DMA commands from target Firewire devices.
I've done a whole lot of Firewire storage firmware, mostly for Wiebetech. The way Firewire drives work is that the Initiator - your PC - transmits SCSI Command Descriptor Blocks - CDBs - the Target - the disk - via the Serial Bus Protocol 2 - SBP-2. (There was an SBP protocol at first but it was withdrawn for some reason).
After that the Initiator sits quietly by until the Target informs the initiator that the CDB has been processed.
I think they designed it this way in part because Targets have limited processing capacity, so allowing the Target to drive the protocol also allows it to control the rate at which work is performed. But you're also trusting your Target to deliver the file the user just double-clicked, rather than overwriting the buffer cache entries that contain
/etc/shadow.One of the very best hacks ever at the MacHack conference was that some guy wrote a FireWire applicaiton that would display an animation of a fire burning in a brick fireplace on the screen of any other Macintoh is was connected to.
The Mac whose screen would show that heart-warming image did not have any extra software installed on it at all. Instead the Mac with the Hack installed would DMA it directly into the other Mac's video memory!

Re:Data Breach
Mod parent up. A good percentage of failed drives happens at the controller level. When a drive is refurbished, sometimes only the PCB controller board is swapped out leaving both the existing platters and data intact.
With regards to data exposure. Who's at fault depends on where the drive originated from. For example, NewEgg gets a shipment of drives from WD or Seagate and then directly resells one to a customer. If it had data on it, that would be the fault of the drive manufacture. However if the drive was returned from a customer and then resold to another customer, that would be NewEgg's fault. For a company as large as they are, it's not that expensive to purchase a stand-alone console in which you can connect a drive or two and wipe it with the press of button. A quick google search shows such a product in the link below.

Re:The reason they took the whole rack....
There is a product called HotPlug that is meant for seizing assets without powering them down. It works pretty slick. Basically, you plug it into the same power strip, flip the switch and unplug the powerstrip from the wall. You can also splice into the cord or outlet if needed.
http://www.wiebetech.com/products/HotPlug.phpInteresting device -- I see on the specs page that it only goes up to 5 amps.
So it looks like I might (barely) be safe on my fully loaded Sun E450 (500W power supplies) as long as I step down the input voltage to 100V.
Of course, my original point still stands that it makes no sense to power an entire rack when all you want is one server. If you can figure out how to cut over to your own UPS, I think you can figure out how to keep power to the server while you unrack it.
-
Re:The reason they took the whole rack....
They don't need to keep the whole rack powered, just the one machine they are interested in, they could power down the rest of the rack and a off the shelf UPS could run it for plenty of enough time to get it to a truck with a inverter on it.
As for the "magic splicing" it is not hard to do, anyone with a basic understanding of electric circuits can splice two live cables together.

Re:guilty eh?
The police don't have a magic way of keeping a computer powered up when they seize it.
I'd like to introduce you to the HotPlug.
-
Re:Law enforcement...Better yet, they can seize the entire computer and move it to their lab without powering it down using Hotplug
All you need to do then is add a SATA based HDD or tape drive and do a dd or similar command using the appropriate write only switches.
-
Re:Law enforcement...
There are devices that will let law enforcement sieze a computer without turning it off, basically using a UPS to power the computer as it's being moved. The device linked is designed to facilitate the uninterrupted transition between wall power and UPS power. It does this using a "jackass trick" which makes a male power plug hot.
The same company also sells a far simpler device, basically a "fake USB mouse" which will send out random mouse movement to prevent any password protection screensaver or similar from kicking in.
It is probably possible to detect and counteract this kind of stuff too. For example many hard drives already contain accelerometers, using them to detect when a computer is being moved is a simple matter of software (or firmware). Of course then you get into another arms race - you get to either transport the siezed computer very very carefully as to not trigger the sensor, or you might just as well have the computer forensics come out on site to do their work. To counteract that there could be some kind of timeout, requiring a password to be entered at least every N hours or the computer wipes itself. Although that would mean either getting up several times at night or having a uselessly long timeout. Although that could likely be counteracted by messing with the clock frequency on the motherboard. Oh, but that's counteracted by an intrusion detection in the chassis itself (already commonly found especially in OEM computers)... if not it's trivial to make one).
The list goes on and on and on. This will always be an arms race. But in the end, security is no stronger than the weakest link. Although $5 wrench cryptanalysis can be mitigated by things like "duress passwords" - a fake password that you give the cops which will either boot a hidden OS like in TrueCrypt (if you ever actually boot that mounting the filesystem writable, my understanding is that you're going to hose the "other" filesystem in there) or a password that will simply wipe the drive if used.
Tl;dr version: Security is hard.
-
Re:TrueCrypt
There's also the chance that authorities moved the computer without powering it down.
-
Re:Will Law Enforcement like this?
Just how are they going to transfer the equipment and data without unplugging or pulling power?
-
Re:Lots of uses for this technology...
Anywhere where someone doesn't have a Hot Plug. I'm also curious what the behaviour is if someone leaves the power on but plugs the sata into a different computer.
-
Re:Huh?
You don't know jack about digital forensics. The first step is to cut power to the machine. Always.
Oh really? What is this for then?

Re:How about...
We use these: http://www.wiebetech.com/products/cases.php
It's like having a proper hard-case for each disk, and although it won't protect them from a fall it makes it easy to line them all up on a bookshelf or in a rack/drawer system and pull them out when needed.
We also read each drive at least once every 6 months to ensure the drive can re-new any weak magnetic sectors/blocks.

WiebeTech anti-static storage box
I like these guys: http://www.wiebetech.com/products/cases.php It's an anti-static, somewhat shock-mounted plastic case for 3.5" drives. I've got about a dozen stacked in a rubbermaid box. It eliminates the stress of the drives banging into each other, even in anti-static bags. I've never dropped a drive inside one of these, but i'll bet it'd survive a modest height.

Re:Incredible
When you're computer equipment gets raided, it doesn't ever get shut down. IF it did, you could just let everything live in a ramdisk and not worry about it.
they use this: Hotplug
That "mouse jiggler" thing that you see sold on thinkgeek and the like and laugh at? That is what it is for.
-
THIS IS STUPID...
... and not just for the obvious reasons.
:-) There is a company that makes a family of devices (can't find it online now, my google-fu is weak) that lets you move a computer without ever turning it off.
1) Plug in a USB "mouse jiggler"--a USB device that pretends to be a mouse that moves the cursor every few seconds so the computer won't go to screensaver or sleep
2) Hook a special apparatus to the power cord that connects it to a UPS so you can pull the plug out of the wall and the UPS instantly kicks in
3) Load the running computer onto a cart then take it down to the station
Aha! Here it is. Watch the videos, they're pretty cool. -
Capturing machines with full disk encryption
Here's the existing approach to this problem.
- Send in SWAT team. Stop user from turning off computer.
- Bring in HotPlug kit and UPS.
- Plug "Mouse Jiggler" into USB port to keep no-activity timeout from causing logout.
- Turn on UPS.
- Plug HotPlug unit into UPS.
- Plug HotPlug unit output plug (a male plug which is a power output) into power strip, or, if necessary, remove wall outlet plate and connect clamp-on connectors to hot wires.
- Unplug power strip from line power. HotPlug unit will switch in power from UPS.
- Plug power strip into UPS. HotPlug unit will recognize this and deenergize its output plug.
- Unplug HotPlug output plug and input plug. Computer is now running entirely on UPS.
- Carry computer and UPS to forensics lab before UPS battery runs down.
- Plug in UPS to keep battery charged.
- Access disk as desired.

Re:seriously...They've removed lot's of sites from the Great Firewall of China, for instance the English Wikipedia, after western politicians said that a change like that would reflect well upon China. They've let western journalists go to many places they can't normally go to Given that the average Chinese person cant read English, its really useful to unblock the English wikipeida, I mean seriously do you think this was anything other than a political stunt. Damned if you do; damned if you don't.
In any case, various *parts of* Wikipedia are still inaccessible, AFAICT Today, many European countries (including mine, Sweden) have governmentally blessed internet blocklists that are far longer than the Chinese one. Really last time i checked the swedish blocklist was against racist sites, and wasnt nearly as big as the chinese one, but maybe im just more of a fan of facts than you. I use a VPN tunnel for internet access, routing only inaccessible sites through as needed. The list is *not* long. However, it's true that I don't encounter all the blocked ones. On the other hand, a lot of the sites I find inaccessible are not controversial at all - for example http://www.swimman.com/ and http://www.wiebetech.com/ were both blocked until recently - I'd guess due to something controversial on the same IP block/range. My list just got a lot shorter (well, I commented out a lot of stuff). -
Try the "hotplug" system
These guys: http://www.wiebetech.com/products/HotPlug.php have a UPS system that syncs itself to a live power line (or so it seems). It might be worth contacting them to see if it can work for this.
-
Re:Physical AccessPlus, now your machine doesn't even have to be turned off for someone to remove it to a forensic lab: introducing HotPlug. HotPlug only works in places where you could introduce an UPS to the plug connectors while they're still (electrically live) connected to the socket.
However, many other countries do use power plugs and wall sockets where you can't get access to the plug connectors while the plug is
still in the socket. E.g. see CEE7/7, which is the de-facto-standard for many european countries or
http://en.wikipedia.org/wiki/Domestic_AC_power_plugs_and_sockets for various plugs and sockets. Some of them might be intercepted via HotPlug, but
I guess that at least for CEE7/7 or IEC connectors it might be quite hard to "HotPlug" them. -

Re:Do it the old fashioned way - shoot em!
....Of course, the hard part is doing something productive with them...
I take the magnets out and use the best ones on our refrigerator. I give the rest to friends for that purpose.
Before doing this I connect them to a drive dock, specifically this one:
http://www.wiebetech.com/products/ComboDock.php
I look at any files worth keeping and copy these to another modern HD. Since HD space is cheap these days, I have several complete DOS drive images on file. After that I let the computer do a multi-pass full data scramble erasure. This can take quite a while on big drives.
After the magnets are extracted, the left over pieces go to a metal recycler. The cases are usually made from many beer cans worth of aluminum. -
Just use a hard drive
Here is an excellent article on the true cost of archiving to CD/DVD. I have grown to distrust optical media more and more. The only CDs I burn now are KNOPPIX discs, OS install discs, etc. Anything important I archive to a hard drive. I have an external SATA enclosure that has a removable tray.
-
Re:archive then move?
The point is not to make them smaller - it is to make them all one file. Of couse, smaller is better too.
I wonder how the microsoft backup too would work in this situation. Backup to a file, copy the file, then restore from it. I've done it in the past, though not for the same reason, and it's worked...not sure about speed.
Clearly, moving the disk would be the best option. I often use a firewire Wiebetech Drive (useful to have around if you often find the need to do such things) dock to perform a similar task - it'd mean you don't have to open one of the cases, at least.
On a side note, why is http://www.wiebetech.com/ inaccessible from China - it's been inaccessible (at least) ever since I arrived here 3 years ago? Groklaw was blocked for a while, but is now ok; Wikipedia seems to come and go ('go' at the moment); even slashdot occasionally does not work; but wiebetech's web site has consistently never worked. Yes, I try from multiple access points...
Curious. -
Other sources for external SATA stuff
No, certainly not the 'first' of its kind, I think cooldrives has had 2 listed for some time and I have seen others WITH internal RAID capabilities. Though I do think this unit has the smallest footprint.
Wiebetech has had 2 external raid sata units out for some time now, with hot swap drives. A SilverSATA line with up to 5 hotswap drives and a RAID 5, the RT5, which also comes with USB and firewire.
http://www.wiebetech.com/home.php
They will do direct international sales but I think they have european distribution.
Another good source of SATA and eSATA stuff is Addonics who also have UK distribution,
http://www.addonics.com/
Specically a custom configured unit,
http://www.addonics.com/products/raid_system/ast4. asp
They have the SATA->eSATA stuff you need to do any external configuration. Though I do not believe thier products do the RAID in the external enclosure.
There are also 'multilane' SATA cables/cards allow you to connect up to 4 SATA drives over a single cable. The drives can then be configured using a RAID array based on the controller in the PC. -

storage-router-print-server + nas = my 2 cents
low power soho server do not use a laptop as a server. do not use 2.5 inch drives unleess your going to buy one of those fancy new sun servers with 2.5" Serial Attached SCSI (SAS) drives. whatever nas/raid solution you do decide on you want to use as few drives as possible to conserve power. so think carefully about weather you want to stripe two 500gig drives or mirror or move to one of the raids that requires more than 2 disks. you need a router right? so now what do you need this server to do? does this server really need to be on 24-7? or is it just a big digital closest? get a router that has a built in print server like the ones from asus. i have one and its the print server and a ftp server useing a flash drive for super low power 24-7 access. this way the raid solution doesnt have to be on in order to access the printer. maybe someone has some info on the lowest power routers out there? figure out your raid level needs, server procccessing needs, and your bandwidth needs first. if the server is just a file server then there are a bunch of low cost nas solutions out there that use very low power proccessors and just do file server related tasks. I WOULD LOOK CLOSELY AT THIS AS PART OF A SOLUTION. this way you turn it off when not in use. if you need more proccessing power on the server then your going to have to first figure out your bandwidth needs to the raid array. many adapter based solutons require 64bit pci slots versus if you can get by with usb or firewire bandwidth from the raid then you can get an external raid array like one of these.. http://www.wiebetech.com/products/rt5.php http://www.fastora.com/product_index.php?doc_name
= raid-300 http://www.lacie.com/products/product.htm?pid=1060 0 there are all sorts of low power front ends you could mate up to these i think. plus, that way you can work directly off the array from your laptop or connect it up to the server. maybe even just plug one of these into a asus/dlink/netgear storage router?? the question is the server has to be able to handle a terrabyte of storage i guess. personnally i would look at the "home theater pc" thing seperately. but some people may argue to set up a htpc with the raid attached to it depending on use. if (like me) all you want to do is watch divix/xvid etc then get a lower power single drive device that you move data on to in order to play it on the tv. just think, do you need to have both the raid array and the htpc on at once? if you want to use mini-itx and build your own then get a fanless one. i have been useing a mx266 from www.bcmcom.com it has sata, cf slot, dual nics, mini-pci for wireless nic, and the 1ghz eden proccessor. i have yet to run this board fanless though, but i think its possible with a aftermarket heatsink. whatever board you get boot it from compact flash. i think that will use less power but im not really sure. with mini-itx you get one 32bit pci slot so if you dont use a usb/firewire raid array then you may end up having to use that slot for a controller or adapter for the raid array. baisicly you need to first put more time into visuallizeing your use patterns and needs. -
no enclosure
Consider not having an enclosure.
I have several Wiebetech Drive Docks that work just fine.
I had the drives free standing on their side (to allow convection), or fixed to a big metal plate to distribute the heat. A desk fan would provide additional cooling
Of course, they also sell enclosures, if you must. -
Upgraded a dual Mac G5 with two of these
I recently ran out of space on my two internal 250 SATA's (I use one to back up the other on a schedule) so I bought two of these with the SATA sled, put the two internal 250's there and installed two of these 500's internally. Perceptions:
1) Whoa. We have space, sir! And lots of it!
2) Slightly, yet noticeably, faster.
3) Seems quieter than the 250's.
4) Installation is a BREEZE on the G5... and quite ingenious as usual for Apple. Their internal hardware design is a joy to work on.
5) The G5 already has a fan pointing at the internal drive bay, so no additional cooling was necessary
6) The 250's happily run in the TrayDock enclosures (they don't have fans, but their all-metal design does conduct heat away well) and I can swap them out after an unmount, live, very easily
7) Did I mention I have almost a terabyte of backed-up storage now, for home use. mmmm, massive media ::cough:: pr0n ::cough:: library...
8) OK, I can only afford this because I am not getting laid lately. Hence no money going to women. So quitcherbitchin' if you're gettin' some. I'd upgrade to some a THAT, given the choice. ;) -
STEP ZERO:Make sure by ordering the right adapter for doing forensic's work that Your Young Apprentice (or PFY) can't screw this up. A read-only adapter means the drive can't be mounted rewritably. No, it's not cheap. But what's $500 to the assurance that your evidence chain is prevented from fuckup at the hardware level?
And no, I don't work for these people. I just think they make some nifty geek toys.
No, that's not why I have SCSI drives on my home server. Honest; it's for the RAID performance....

WiebeTech!!!
WiebeTech http://www.wiebetech.com/ has some of the best FireWire and USB solutions around, I've been using their BayDocks for video editing for a while, and never had one failure. (knocking wood) Their ComboGB drive, with USB2, and Firewire 400+800 would probably serve your needs well. Disclaimer: Simply a satisfied user / not affiliated with the company in any way.....

Cheap hardrives with firewire enclosurehttp://www.wiebetech.com/products/ComboDock.html
Makes an cheap, fast way to put lots of data onto lots of hard drives. Using one of these bad boys means no extra money is spent on drive enclosures, cases etc. You only buy raw standard hard drives. Excellent if it's only backup, and you do not need lots of access. This solution is not automated however.
Hard drives are prone to failure. I was thinking of buying at least 2 drives of different brands to mirror, storing them in separate locations in sealed, air tight containers at just the right humidity/temperature. Also I think a disk check every 6 months or year would be necessary, and if any problems are found, replace the disk with another.
One beauty with this method is you only need to pay for disk space as you need it, and hard drives may still get much bigger. I was going to buy drives at the lowest cost/megabyte which at the moment is 160GB drives.
I would love to find more information on the physical storage of hard drives, especially how long they would be expected to last without use - months? years?
