I have an old Pentium III computer with FreeBSD 5.3 and I am using GEOM
GBDE encryption on a few IDE-disks that are mounted on a PCI-ide
controller.
I had some important files on a less than 1 year old 300gb Maxtor
harddrive (ad5) when it stopped working. The harddrive had been working
ok, and it had been in the computer all the time, so no risk physical
damage. Then I mounted and attached it and tried to move a few gb's of
files to it and I got lots of WRITE_DMA errors all over the terminal.
Then the computer crashed, next reboot I could attach it with gbde but not
mount, due to I/O errors, and fsck said incorrect superblock.
After second restart the computer could not find it,
and the dmesg from the third restart is shown below.
What shall I do to get my data back? I have approx 200mb of critical data
there that I need to get back..
