I had a, Hard Drive connected to my computer via PCI controller card
as master on IDE2 (another master disk on IDE1 was the boot disk with
windows). I unplugged the hard drive from IDE2 and put it into an
external firewire enclosure, then plugged it into the 1394 port of my
laptop. It seemed ok.. The disk showed up fine and the directories
were all there. I then fired up Nero and attempted to burn an iso cd
image file from the Hard Drive to CD-R. Or so I thought. I now
think Nero was set to use the virtual device image recorder instead of
the physical CD recorder. So instead of burning the image to CD-R it
created a Nero disk image (from the ISO disk image) on the hard drive.
This writing to the drive must have caused corruption. The cd image
was created without error from Nero, and the drive tray ejected (I
guess to insert the cd to burn the image to. At the time I just
thought the cd had just been actually burned to the CD-R). I then
re-inserted the cd and it didn't autostart. I opened the cd drive in
windows explorer and got an error saying the drive is not accessible
and "the file or directory is corrupted and unreadable". Here is where
it gets bad. I noticed the hard drive (on IDE2) no longer had its
label "Temp", now its just labeled a generic disk.. so I clicked on
it to see if it was still intact and XP said it was unformatted!? I
took it out of the enclosure and hooked it back up in the desktop
computer and booted. It said a disk is corrupt and ran a scandisk
with full surface scan. After all that, it was showing up as
unformatted in Win98SE too.
I used this disk as temporary space so I formatted it with no primary
partition. It had one extended partition with one 250 GB logical
partition. I tried mounting it under Knoppix and got an error that
the filesystem wasn’t identified. I'm currently running GetDataBack
and its finding some stuff.. says it'll take around 5 more hours.
The enclosure is a CompUSA 3.5" Aluminum External Enclosure. It uses
the Prolific PL3507 chipset, a Combo Hi-Speed USB and 1394A (Firewire
400) bridge controller. I've seen a few posts on the internet
complaining of data corruption from the firewire port using this
chipset. I've also seen reports of errors due to the "delayed write
failure" bug in Windows XP SP2. I never saw any errors but I didn't
move or copy any data to the drive.. the only writing to the drive
was by Nero as it created a new Nero image ( *.nrg ) of the CD (
*.iso ) image. I thought the problem was probably an inconsistency
between the disk controllers when I moved the disk from the ATA 133
PCI controller card with Promise chipset to the enclosure with the
PL-3507 chipset. If anybody has read this far and noticed any red
flags please post them.
