The heads or the servo track is failing on that drive. Loud clickety-CLACK noises are the drive slamming the head back to track zero in an attempt to reseek when finding a track fails. That, and the fact that you get difrrerent badblocks every time indiactes it's not actually bad blocks on the disk.
Whoever suggested you could fix a mechanically failing drive with an image restore was a complete moron.
Back up your important data pronto and replace that drive. No other way to fix it.
All IP-tunneling applications, and the users thereof, violate the DMCA because they could be used as tools that defeat Apple's copy-protection measures?
Yes and No. It's a good idea to treat phone lines, and more importantly self powered phone equipment, as if it had dangerous voltage on it.
Here's why:
Resistance varies from person to person, and from body part to body part. It's lower across wet (espeically sweaty, because salt water is an excellent conductor) skin and even lower, (only a few ohms) across mucous membranes (As in touching your tongue to a 9V battery. Others perform "personal" experiments with guitar amps.)
Anyway, Phone lines carry office voltage, or -48V.
This is almost enough to overcome the average resistance of the skin and electrify nerves and other tissue, causing a shock sensation and possibly other effects, such as muscle spasms or localized skin burns.
Some people can feel 48V. Most can only feel it when the voltage is applied as a sharp point that presses into the skin. This is most likely to happen when you're messing around in a PC that still has the damn modem plugged in.
The 90V of the ring signal is high enough for anyone to feel, and the current is at dangerous levels. After all, it has to be able to travel miles of copper and still ring an electomechanical bell. That takes some decent current. The risk of actually getting fried is low because the ring singal is momentary. Even if it grabs you, it's gone in seconds. However, those with pacemakers should beware. The ring signal could easily stop your clock (and it has happened!)
Telephone EQUIPMENT is actually dangerous. On a phone line the current is low enough to be harmless. However, in the CO, or in a PBX, T1 Frame, DSU/CSU, anywhere serious equipment is powered off the -48V, the current at that voltage is most definately high enough to pose an electrocution hazard under the right conditions.
I have the older Z-560 4.1 system. Let me just make a few comments on the supposed 500 watts (400 in my case) and general sound quality:
1) I highly doubt the Z-680 is 500 Watts RMS (or the Z-560 delivers 400 W RMS). It just doesn't seem like the heatsink on the amp is big enough in either case, let alone the speakers. Also, those figures are way out of line for the price range. I also doubt Klipsch delivers the power ratings they advertise, but at least they say it's x peak watts, so you know the number is meaningless.
2) I don't care about wattage. These things can play LOUD without any distortion. While it's stupid to turn the volume up so loud you can't listen to it, what's important is the amp and speakers have enough headroom for clean dynamics at a reasonable listening level. These thing have it, and then some. Still, If I cover my ears and crank it, i don't hear any clipping, not even from the sub.
3) These speakers sound as perfect as you're possibly going to get in the price range. Subjectively, I decided they even beat out the Klipsch 4.1/5.1 systems for timbre and bass clarity.
4) Like all speakers, and especially sub/sat sets, you have to position them right for the best sound.
The plastic/cloth grilles of the sats are NOT sonically transparent. They tend to roll off the high ends and disperse the sound. If you can get away with it (no kids or pets, etc) remove them. Not only does it look freakin' cool with their shiny "bullet cones", it improves the size of the "sweet spot".
If you need to leave them on, aim the speakers directly at your ears for the cleanest high ends and imaging. As for the sub, put it near a wall, but not up against one, and make sure the port on the left side has about a foot or clearance ound it, or you'll lose the lowest frequencies... so if you can stick it towards the right side of your room, do so. (The sub is a lot less touchy than most for placement tho, cause it's well built)
5) Turn the bass down, down, down. That sub is a monster and I wouldn't doubt if it DID have close to 200 watts on it. On the z-560s with the analog control pod, I get the best bass with the knob at minimum. Anything more is just too emphasized. Not boomy or distorted, just too strong.
1) Yes, they allow 4 machines for residential. This was not residential.
2) This was a "lo-cost" (at $99/mo??? what a joke) business DSL, static IP (actually DHCP, but always handing out the same IP) and it was 768/768 SYMMETRIC DSL, not your 650/320 ADSL. Totally different service.
3) I don't care what their web page says for residential services, this was a "limited" business account and the rep bitched them and me out for having a NAT.
Do 99% of the Anonymous Cowards out there even read the posts before flaming? You're talking about a totally different service than I was. I will give you soem credit: you are right about frying eggs on the Speedstream boxes. Theirs didn't get a chance to burn out, we dropped AT&T and got Verizon.
I suspect the techniques discussed in that paper have been used for quite a while by AT&T, but they have been rather secretive about it.
About nine months ago I got into a bit of a sticky situation at work. One of our clients was running three PCs behind a NAT we installed. The DSL provider shut them off repeatedly for having "more than one machine per connection"
Mind you, this was AT&T business-class SDSL. Static IP, 768k/768k. They were certainly paying enough for it.
I talked to the ISP. The very rude and condescending rep told me they have software that can detect multiple machines behind a NAT, and that the customer had been warned and disconnected multiple times for it.
(No, we didn't take responsibility, because the customer didn't inform us the contract precluded NAT usage)
I asked the rep how they could detect this. The rep didn't know but said it was something called Option 82. I'm assuming this is DHCP Option 82, Routed Bridge Encapsulation. I don't see where RBE has anything to do with this, unless they were using it to sniff the connection between the NAT and the DSL router.
You can't blame the inventor of video games or the games for the way the younger generation turned out. As an example, if Pac-Man influenced kids, they'd be moving around dark rooms to repetitive music, eating lots of little pills, and chasing or being chased by hyperactive neon creatures.
Oh wait...
Ravers.
Never mind.
Considering most laptops now have Li-Ion batteries and most BIOS code is shadowed in RAM and can be modified by the OS (assuming you have root or administrator privs) it could be one NASTY payload for a virus.
Forget quarters. No one said a thing about quarters or even keeping a PHONE in the booth. Make it a police call box, taking care of the emergency-phone aspect at the same time. Wi-Fi antennas can be tiny and on the roof of the thing.
The way it would probably be done is via PPPoE with a pretty user interface.
My phone company (Verizon) has residential DSL using PPPoE, so why not run that over the Wi-Fi? The Verizon Online back-end is already in place. You can control bandwidth, you have accounting, and you have authentication. The charges would show up on your Phone/DSL bill.

MAN didn't always come before woman. Before the term MAN was coined there was the Metropolitan Area Ethernet. MAE West (and MAE East) anyone?
