Oh-oh. Ext FW drive shuts down my Mac and PC when I plug it in - the_poochies - 07-28-2007

I have an Acomdata 250 GB ext FW HD. Suddenly, whenever I plug it into my MacBook (10.4.9), it immediately shuts down my Mac. Ditto when I plug it into the FW port on my PC. When I plug it into my Digital Audio DP G4, it doesn't shut down. But no computer recognizes the drive any more. The drive seems to boot up OK, but it's not recognized. Any ideas on what's wrong? The drive holds my iTunes music, so I am pretty freaked out if the data is lost forever.

I tried different FW cables, with the same result. Other FW drives work fine with my Macs and PC.

Try the drive in another enclosure.

Stop using that enclosure.

Backups, backups, backups.

I backed up the drive on another FW drive that also went down the crapper. Luckily, I burned everything to a few dozen DVDs last week.

Try booting the digital audio G4 into OS-9 and see if that set up will see the drive.

I've spend much of this week with a similar problem; a firewire drive that stopped mounting on the OS-X desktop. System Profiler reported the drive as attached but unformatted; Disk Utility reported the same and would only format the drive. Diskwarrior did not acknowledge the presence of the drive. Now in my case it did not shut down the computer!

I ended up booting into OS-9 on my Powerbook G4 and then the drive would mount. I tried using TechTool Pro to repair the directory and TTP tried to do so. I could see the files, but booting back into Tiger I got the same "wanna format this drive" message.

Fortunately, I'd ordered another firewire drive and in OS-9 I could copy the old files to the new drive. THAT drive mounts in OS-X just fine so I managed to rescue everything (fairly recent backups would have made the loss minimal, but inconvenient).

So try booting into OS-9. If you have the same luck as I did, you'll be able to access the files and move them to a CD-R or another drive.
