USB Drives — Recovery?
pipingguy writes "Now that 'thumb drives' are so inexpensive (a 1-GB SD card with USB housing/adapter costs about $25), which programs does Slashdot recommend for system recovery? What is the need-to-have software? Additionally, I'd like to get some input on the durability of the newish card reader / adapter devices, as some of them seem to be pretty flimsy (but very useful/flexible as opposed to the old fixed-capacity NAND devices)."

As far as thumb drives go I'd recommend the Titanium Cruzer which comes into up to 2 gig models. I keep mine on my keychan which is outiside on my harley 365 days a year. Rain or shine, and here in Florida we get a lot of rain. I've pretty much abused it much more than I expected to and it's never failed me once. I'll leave others to comment on what to put on it but if you're loadking up a pice of crap that's what your going to have just when you need it at your clients office. Quality tools pay for themselves.

To start with, there are even less expensive methods than the one you mention, the first of which that comes to mind being the $10 1gig usb flash drives at microcenter.
On to the bit about recovery. You say system recovery, but use those words to link to a usb flash drive. Did you mean recovering data from said flash drive? If so, the data on those works the same way it does on a hard drive. The system deletes a file from the tree, but leaves the data intact until written over. Any standard undelete program will recover files you've simply deleted.
As for backing up your system to a flash drive, I wouldn't recommend it unless you're running a small enough footprint to fit on one. The 8gig flash drive are getting to be reasonably priced, but that's still not enough for most full system backups.

PhotoRec is data recovery software specifically designed for recovering lost photo files on corrupted memory sticks (CompactFlash, Memory Stick, SecureDigital, SmartMedia, Microdrive, MMC, USB Memory Drives...)
DOS, Win, Linux, Mac versions available here.
I've had good luck with TestDisk when a partition has been deleted.
I was formatting a PC and installing a fresh copy of XP on it. I had backed up all my data onto my thumb drive first. However, when the option to choose the partition to install XP came up, it displayed my thumb drives 1GB partition. I had forgot I had left the thumb drive plugged in, not realizing what the partition was I deleted it (but didn't format). After realizing my mistake I used TestDisk and it recovered all my data.
The first thing I would do is build a self-contained Debian install, then you can add any tools from the Debian repositories with a simple apt-get.
For examples of how to install and configure everything check out the Howtos and Automated Installer at Feraga.com.
One nice thing about these drives is that the filesystems can be read by any OS without hassles. This means we can include both a Mac and a PC binary (and a Linux one, once I get cracking on that) for indi on a drive and you can move your data from machine to machine with nary a hitch. Good times.

Why bother waisting time with recovery procedures? Do a proper backup and make a quick install CD, containing needed drivers/apps and such... I made a DVD with my favorite Linux distro, in a subdir a list of RPM's and the important config files , all the extra RPM packages needed are in a private repository online.
Its not exactly designed for thumb drives, but its saved my hide numerous times:

Im pretty sure that if you can boot of a thumb drive, it wouldnt take too much to make this work.
I have a copy of the latest version with me at all times, in my wallet, on a mini-cdr.
All freeware tools, including a full fledged linux (Insert linux i think its called),
dozens of msdos utils, net stuff, iirc there were bios flashers in there too at some point.
Xcopy alternatively xxcopy if you're nasty.
Stuff too big? Pipe it into an archiver.
Seriously, proprietary backup applications have been obfuscating and fucking up what these have been doing for years reliably for 99 percent of users.
Platform advocacy is like choosing a favorite severely developmentally disabled child.
Most data recovery services can recover data from these devices, as long as the chip is intact and the data is still there.

My wife and I are having trouble conceiving. What program does Slashdot recommend?
In my tech support days, we took walk-ins from all around campus with corrupted floppy drives. We always recommended that they switch over to flash drives to get rid of this constant problem. Then, a few weeks later, someone brought in a 1 GB corrupted flash drive... and we sat there for an hour as BadCopy Pro did its work. Norton Disk Doctor, BadCopy Pro work very well at file recovery from failed disks that say that they need to be reformatted before they are read. They're old tools, to be sure, but they still work on whoever has a floppy and they also work on flash drives. Sure, they can be slow (sometimes it took 10-15 min to recover a single floppy, an hour to recover said 1 GB flash drive) but they really do the trick and will be able to recover the files pretty well.
Distrowatch is a great place to find forensics/recovery distrobutions. When I have to recover a system (be it Windows, Mac, or Linux) I've found that pretty much any Linux liveCD or USB forensics distro will do the trick. From editing/fixing partitions to recovering data from a dead OS to fixing a botched install of an OS the tools are all there.
I have an Intelligent Stick--mine's served me quite well and fits inside my wallet (I don't like things on my keychain).
In case you look at it and think it isn't a USB drive--it is. You can get an adapter to make it look more like a normal USB drive, but then it doesn't fit in your wallet!
My USB drive is filled with bootable images for syslinux, you can load kernels and boot floppy / harddisk images using memdisk. I partitioned my USB drive as a ZIP drive for improved BIOS booting. I currently have different Fedora kickstart options, a Fedora Rescue, Gentoo LiveUSB, memdisk86, Seagate Discwizard and Dell Diagnostics.
I haven't used it from a USB key myself but after some googeling it appears it is possible. The LNX-BBC kit at http://lnx-bbc.org/ has saved my bacon several times! Of course I started using it when people thought a business card CD was a good idea.....does that make me old? You young whipper snappers and your fancy USB keys!

System recovery from USB sounds good, but I've never used it. CDs are still cheaper and easier. I can see it being the way of the future, avoiding the CD writing stage, but most machines still work better with CDs. The recovery tools for me are still Knoppix and Debian images. Apart from the recent AMD intiramfs tools problem, I have not had a system fail in years. The real future is systems that simply don't fail and need to be "recovered." Outside of system recovery, I make lots of use of flash memory and can offer you feed back on two types of card readers.
PC card style readers for laptops are very durable and inexpensive. A MMC reader can typically read six or so different kinds of flash cards. "Compact Flash" format readers are equally durable and even cheaper as the format fades away. All mount like any other media in Konqueror's "system:/media". Most better laptops will boot off of them.
One of my music players has a SD slot in the back and I often use it as a usb card reader. It has lasted more than a year and works just fine. Some Windoze systems prompt me about "RaveMP", which is annoying but it works great in the normal software world as a simple USB fob.

This company can recovery almost anything, for a price, I suppose it depends on how important your data is. For me, a year ago my LaCie 320 GB Big Disk Extreme striped RAID array failed (one drive burned-out). Normally, if the drive was one single hard drive, it would have cost a very affordable $700-$800, however, the striped RAID array required disassembling two drives, removing the platters, reading them inside a clean-room environment, splicing back together my data, and placing it on another LaCie 500 GB Big Disk Extreme for $3500.00! Of course, my thesis was on this drive and I wasn't going to graduate without it! So, as mentioned before, data recovery depends on how important your data is. If your life or future career is on the drive, then the price of data recovery may be money well spent.
Trueimage is the best thing I have found for that.

now if only compression got better, I could dump movies and jazz on to flash for cheaper than burning CDs/DVDs... backup software? uhmmm meh? who needs software when you can just backup your vital documents? besides my mac boots into single user (unix command-line) mode, that's 99% enough to tackle a problem.
I put a working 80gig IDE drive into a $30 external enclosure and when Windows XP popped up the USB device install I was so psyched I nearly shit my pants.
An hour later my PC freezes up (as is routine) with the USB drive still mounted.
Upon reboot, the drive refuses to mount.
Many hard disk data recovery tools recovered the files BUT I have yet to find anything that will mount and wipe the drive.
As far as I know it is permanently corrupted. Which seems like it should be impossible but here I am with this piece of junk sitting on my desk silently laughing at me.
A program I have been using to back up the main Win partition(also it can backup ext2 and 3, and has a linux client/server!) is acronis true image. After trying to use that garbage, Norton Ghost, I went looking for alternative imaging solutions and found that. Its pretty tight, it can compress images and restore over the network. Although, it "cost" me $999(Well it costs 999 for the Enterprise version...) but I got it "legitimately" cuz its so worth it... Anyways this program is 10x better than the recent versions of Ghost, and doesn't run a million and one processes on your computer, and the couple of processes it does run are pretty light in resource consumption.
md5deep values of /bin /sbin etc. helps me sleep at night, provided I remember to check they match from time to time. As for keeping the binaries on the thumb drive itself, why bother, there are plenty of live-distros that cover just about everything you need for recovery, and even if they don't, it's trivial enough to make one that has exactly what you need.
(FYI, I run windows)

normally, I use "restoration"; it's a great application to recover deleted files. It supports all MS operating systems and all MS filesystems, it's small, free and required no installation so you can run it from a floppy, which is nice. I never had any problems with it on various HDDs, USBs, SD cards and XD cards - until:
My USB thumbdrive generated the following error in windows "The drive is not formatted" - oh bugger. But after trying many different applications (and buggering the drive further in the process - it ended up not even recognising that there wa drive there at all), I found PC Inspector File Recovery, which did manage to recover all my files. I still stick with Restoration for most of my needs - it's a cleaner looking app, but if/when it fails, I look to PCiFR.
The reason I don't use PCiFR all the time? As I said, I don't like the interface, you have to install it (and if you install something on the drive that you need to recover data from, you run the risk of overwriting the data) and Restoration is small. They're both free.

That's kind of beside the point, since you don't want to do a by-file copy: you're wasting a little space by allocating trailing blocks and a lot of space by not using compression. You have to use an archiver anyway, and it isn't hard to find one that will preserve all the file attributes you care about.
What's really painful about FAT is that no one file can be more than 2 GB. So if you anticipate creating an archive that's bigger than that (after compression), you need to use an archiver that knows how to do multivolume archives
For Mac users (whose machines can boot from firewire devices) I can recommend the http://www.kanguru.com/fireflash.html.
My 4gig unit is tough as a brick: hasn't failed me once (i.e. dataloss) and it has helped resurrect machines several times.
(somewhere, sometime, I'd read that that Firewire (400) is faster than USB2 (480) because there's less 'overhead' in the data packets. can anyone verify this?)
"It's time to take life by the cans." ~ Bender ("Bendin' in the Wind", ep. 3-13)
What programmer in his right mind would do this? It does not really make things much easier to use, and often causes accidental data loss such as this. I've even seen similar issues on Linux installs--Ubuntu has a warning sticker about the default being to wipe out the hard drive. A friend accedently wiped out his second hard drive with a red hat install and his network drivers were on the second drive, no floppy, he had to go out and buy a cd burner (they weren't the cheap things they are today). I suppose it gave him an excuse to his wife for buying new hardware. ;-)
Just seems like another stupid thing people have been brainwashed into thinking it is "easy" to use, but in reality it is not.
I have the I/O Data Mini SD USB adapter I picked up for $10 from CompUSA for my phone, and the thing is flawless every time. Also giving me the ability, as I upgrade my cards, to use the old ones as flash drives...
dd if=/dev/sdx of=flash.img
cp flash.img tmpfile.img
bvi tmpfile.img (repairs made)
dd if=tmpfile.img of=/dev/sdx (new flashcard)
Spinrite for $89 is a lot cheaper - and you should always backup important data or just use any other RAID level then zero. Masters thesis? Yet you didn't know to have a backup copy?
Leave school ASAP and learn some common sense in the real world.
It's the Microsoft machines that have 99% of the problems.
And most of the tools that have been mentioned here are for 'fixing' Windows machines.
Kick the Microsoft addiction, the withdrawal is worth it.
You are being MICROattacked, from various angles, in a SOFT manner.
I really doubt the legality of this one but Hiren's BootCD must be one of the most complete solutions. SVP also sells real cheap microSD-adapters which can probably make a nice small drive, but microSD-cards are much more expensive than miniSD and SD so maybe it's a bad idea.
I carry the full PortableApps suite http://www.portableapps.com/ (89.5MB) on one of my Transcend my 2GB SD card that I swap between my camera, Treo 650 & a Rosewill SD/MMC USB 2.0 pocket card reader ($5 at http://www.newegg.com/. here is a list of some of the apps included:

I would have read the sign they have that says they're not responsible for the data on your hard drives. Most repair shops have such a policy, although most will try to not damage anything.
Why does the link under "system recovery" go to a USB flash drive wikipedia article? The strange links in the blurbs often annoy me. Ok I see it has a couple references to recovery but maybe a recovery article of some type would have made more sense.
Here's a data recovery company I know:

This is a great all-in-one recovery kit on a single CD that also supports being loaded on a USB pen drive. The ISO image clocks in at around ~150Mb, is a pretty complete linux (based on Mandrake) with built-in sshd, smb support, partimage, and a good double-handful of useful recovery tools. It's designed for cross-platform support - the full suite of ntfs-tools are included as well. I have been using it to clone baseline builds of my production systems at work and it is excellent. Fast boot and a good selection of boot options as well. Can be had at http://trinityhome.org/. Check out the latest beta for even more functionality.
First of all, don't forget that the inexpensive USB-flash cards that are sold are mostly 6 MB read / 3MB write devices, while the more expensive ones are about 25/20 MB respectively. If you want to fill 1/2 GB on a regular basis, I would opt for the faster one (the so called 100X-150X speeds).
The quality of the card readers does not make any difference, it's the flash that stores the backup. The readers can be bought anywhere for about 10 dollars, so what's the problem?
As said, USB-drives are just another backup medium. Since they are random read/write, I would use any backup application that can handle removable disks. I would not care too much about the limited number of writes, since it is very unlikely that this would matter if you back up only dayly or weekly.
I've read most of the comments and I was surprised that I didn't see his main question answered. I don't think he's saying what would you use to recover them, but rather what you use to recover other systems with them.
Personally, I have:
a copy of firefox installer
putty (et al)
wget
portable firefox

I'll admit it's not very well rounded but I've only worked on a few computers and that's what I needed.
I use a USB drive and Acronis True Image. It gives me a number of options which I like:
:-) - I always do a full backup to the USB drive.
(1) scale: I can back up files, partitions and complete harddisks, even though half of it is Linux (limited to ext3 support, though).
(2) versioning: I can go back to previous versions of files
(3) multi-layer backup: you can also back up to a separate partition, but I didn't do that (not enough space
(3) recovery CD: it can toast a boot CD for you which allows you to boot up with a zapped harddisk and rebuild from scratch. This is also the way to move data from one system to another as the partitioner is flexible.
Works for me, but be aware that a USB drive is slooooow - even on USB 2. Maybe a Firewire disk is faster...

We do not need 'tools' on 'thumb-drives. What tools are there, especially the 'U3' ones, are actually tools for spying by unknown entities somewhere on the internet. I bought one of these 'devices' and it came 'preloaded' with 'useful utilities' for 'WinXP' and all other flavors of windows except Win98 which evidently was sold with no permanent malware istalled outside of secret federal government viruses (later used to ground Sadaam's air force in 1991). Chief among these was 'U3', the company(??!) that 'made' it. If inserted into any hacked windows (above win98) computer, it instantly installed itself without asking permission! I have no knowledge if it would 'ask' anything at all and do not want to find out, so now I am lighter by twenty dollars for this. I looked at the thing in Linux, and it has viles (files) on it that cannot be removed even by linux. That says that those files are on a prom that is memory mapped into the memory space of the memory chips comprising the main memory of the device. Evidently those files have some way of being changed, as there is a routing in the malware that installs itself in windows that continually seeks out the internet for possible 'updates'. So there you have it. Do not plug these things into a windows machine or you will get hacked or botted. I can only use the thing for linux, as they cannot do anything with linux machines.....yet! I have all my windoww machines isolated from the internet so no matter what somebody does with them, they cannot spread it.
Personally, I find the Ubuntu Live USB has just about everything you need, and anything you don't have can just be added because it works in "persistent" mode. In this mode, any additional utilities you install, settings, etc. stay on the USB stick.
I got mine pre-installed from these guys. Works great, and it has GParted Live included on it too, which I've used successfully loads of times for resizing Windows partitions (including NTFS).
Keep in mind that that most of the Cowon gear
mounts as mass storage too(mine is an iAudio U3).
And it supports open compression standards such as Vorbis and Flacc.
gawk; talk; date; grep; touch; unzip; strip; touch; gasp; finger; gasp; mount; fsck; more; yes; fsck; gasp; eject; umount; make clean; make mrproper; sleep
Or maybe just "spawn".
My Creative MuVo TX SE 1Gb once was once able to boot-up in BartPE (UBCD4win), running a full compliment of virus scanners, disk recovery solutions (GetDataBack). You could also just stick in the USB to an XP system, and have access to installed apps that way too.
Only I got too cocky building it up, and then one day it wouldn't boot up anymore. Damn, I miss having it running 100%.
But it is still very useful even if it doesn't boot-up le machine; plus it plays MP3s nicely, so I'm likely to have it with me as I cycle around town, and use public transportation.
BartPE on such an MP3 player is a laptop and OS all unto itself. What a beautiful ~$50 mobile disaster-recovery workstation!
If anyone knows a trick for reliably getting such an MP3 plyer-type device to boot-up, please clue me in! (Storage is trivial, boot-ing up, with Dual OS loaders is where it's at.

I made the mistake of buying some last time I was in Cambridge, Ma visiting my parents.
They are great sticks, USB 2.0 compatible*, and overall great if you dont mind the fact that they only work at 11mbps.
I contacted the manufacturer, which promptly responded that they would look into it, and never heard back.
