Yikes! Hard drive not readable	Can't Post

I have an external HD in a FW enclosure that has been working fine. It is only about 1.5 years old and has not had heavy use. A few times on my Quad when using it in the front FW port I get an error that the device was unplugged without ejecting it, this was not the case, I am not sure if I have a bad FW port. Anyway, I plugged in my HD and now nothing comes up on the desktop. In the system profiler it is there and can read the capacity of the HD, but no HD icon appears on the desktop. I tried it on my PB with the same results. I then removed the HD and placed it in a new enclosure thinking maybe there was some miscommunication. Nope, same thing. Any suggestions? I have vauable data on this particular drive and need to get ot off, but I can't acces it for some reason. Thanks.

UPDATE: I now plugged in one of my other drives and I can access it but whenever I try yo copy a file to my desktop I get this:

Operation could not be completed
I/O error -36

OK, Update number 3. Ran disk first aid on the drive and got this:

Disk Utility stopped repairing “Untitled” because the following error was encountered:
The underlying task reported failure on exit

Verify and Repair disk “Untitled”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid record count
Volume check failed.

Error: The underlying task reported failure on exit

1 HFS volume checked
1 volume could not be repaired because of an error

I have a feeling something got screwed up when the signal got interupted from my quad and the drive was ejected. I keep having eject issues with my desktop quad. I will eject the external drive, the icon disappears I wait a few seconds and unplug it, then I get the device removal warning saying I could have lost data for not ejecting it properly. OR I get that warning in the middle of working when I didn't physically eject the drive! I am gonna have to take my quad in for a look at Apple I think....

What gives? Mad

Sounds like its just not wanting to mount. I had this happen once and used Disk Warrior to remount it. The other solution would be to pull it out of the enclosure and use it inside your tower as an internal drive. I have done both methods and got the results I was hoping for.

I may have to buy Disk Warrior. I won't be able to mount the drive in the tower. The drive is an ata and I have a Quad which only accepts SATA drives. Sucks.

I'm with Hollywood on the Disk Warrior thing, run it immediately. If nothing changes, you could try another case but the dismount thing is my concern. I've seen behavior where a drive dismounts under heavy I/O and it has to do with the drive itself issuing retries and (apparently) setting the S.M.A.R.T. flag which makes the OS drop it. On restart everything is fine again.

Backing the drive ASAP (if it has valuable data) is a good idea. If you have a system that can accept the drive internally you could start monitoring the S.M.A.R.T. flagging with Disk Warrior.

If the event recurs soon, check your system crash logs to see what the crash scenario was...

Bottom line is, if it's a S.M.A.R.T. thing, the drive is probably dying.

I'll have to go out and get disk warrior. As it stands now I can't even access the drive to get any data off of it, which is very problematic.

I tried it in another case with no luck as well...I just hope I can get my data off of it, several hours of video footage on there. I also can't figure out why my quad does this with disks. It does it with all my drives (kicks them out without ejecting).

You should have Disk Warrior irrespective of this problem.

You may still be able to retrieve the data using an older (ATA drive based) system. Or, DW may be able to find it.

"I also can't figure out why my quad does this with disks. It does it with all my drives (kicks them out without ejecting)."

As I mentioned, my big system does this as well. Perhaps it's something in the late-release disk I/O. In the case of externals, it could also be a cabling issue, but the instance I cited was with internal disks. I've yet to find anyone at Apple who I can work with on this; the events are pretty random.

Use DW on your system drive too... it can stop some weird behaviors.

I had the same exact thing happen to me two days ago. The Lacie folks recomended going to prosofteng.com
and purchase data Rescue II. I was able to recover the data AND restore the drive with no problem at all.

Thanks Ivey. I am planning on trying Disk Warrior tonight, if that doesn't work I'll try that product.
