Hey Everyone,

I have been running a LaCie 250GB d2 Hard Drive Extreme external hard drive connected to Airport Extreme as a network disk and everything seemed to be fine until I upgraded my iBook G4 to 10.5.1. I am also running a MacBook Air which is now fully up to date with 10.5.2. Neither machine can access the drive through Airport or directly connected vis USB.

I have done everything short of swapping the HD case or bringing the drive to a disk repair specialist. Below are some of the things I have tried:
Disk Utility, Disk Warrior, Data Rescue 2, FileSalvage
System Profiler - check USB
Swap cable
Mounted a friends USB drive, worked fine
Zapped Pram etc.
Booted to Install disk, no external drive
Spent an hour with Apple Tech Support trying all the same things, no luck
Probably a few things I can't remember at this point

It's obvious that the drive has issues and both macs seem to be fine. From what I can gather reading various posts most people seem to think the problem might have stemmed from the host computer that the drive is mounted to going to sleep or being shut down without ejecting the drive first thus damaging the file tree or something like that. I'm not using Time Machine so I don't think any of the drive issues surrounding that are related, but maybe?

When I spoke with Apple Tech support they had no record of anyone filing a complaint along these lines, although it seemed I read a few posts where people had mentioned they reported the situation to Apple. I can verify that I have now filed a report directly with an Apple Tech person named Paul on Sunday 4/27/08 at apprx. 2pm.

At this point, I'm kinda ranting since I'm a bit frustrated and of course I don't want to loose my data! I'm not sure if I should try replacing the case or just take the drive to a disk specialist. Anyone have any other suggestions?

I guess I'm mainly just curious to know if this problem is going to occur again if I get the drive fixed or replace it with a new one. I mean, it's quite possible the drive may be bad, but it seems many have had similar problems.

Any comments or advise would be greatly appreciated.

Thanks,
Scott

What happens when you run DiskWarrior on that drive?
(Connect the drive to your Mac via USB and restart from the DiskWarrior CD.)

Actually, I downloaded DiskWarrior so I don't have the disk to boot from. I did boot up from the OSX install disk though and tried using Disk Utility from there and was still not able to see the drive.

Do you think booting up from a Disk Warrior disk would make a difference?

So you don't even see the drive in Disk Utility? (Your lack of detail in your initial post did not make that clear - I assumed you merely meant that you had repaired the filesystem on that disk using Disk Utility's "Repair Disk" but that it still didn't mount for some reason.)

If you don't even see the disk in Disk Utility (and I presume the same is true of System Profiler), then that likely indicates a hardware problem.

Do you think booting up from a Disk Warrior disk would make a difference?
I don't know - but I think that is what Alsoft recommends.

Sorry about not making that more clear. The drive does not show up in any of the disk utility programs.
