Hi,
one of our IDE disks failed (btw these WDC AC31600H are particularly
bad, we have had at least 10 failed units out of about 20; luckily they come with a 3 yr guarantee!)
Feb 17 11:38:26 labinfo2 /kernel: wdc1: unit 0 (wd2): <WDC
AC31600H>, 32-bit, multi-block-16
Feb 17 11:38:26 labinfo2 /kernel: wd2: 1549MB (3173184 sectors),
3148 cyls, 16 heads, 63 S/T, 512 B/S
and now we are stuck with this:
labinfo2# fsck /dev/wd2a
** /dev/rwd2a
CANNOT READ: BLK 16
CONTINUE? [yn] y
Feb 17 12:02:54 labinfo2 /kernel: wd2a: hard error reading fsbn
17 of 16-31 (wd2 bn 17; cn 0 tn 0 sn 17)wd2: status
59<seekdone,drq,err> error 40<uncorr>
Feb 17 12:03:01 labinfo2 /kernel: wd2a: hard error reading fsbn
17 (wd2 bn 17; cn 0 tn 0 sn 17)wd2: status 59<seekdone,drq,err>
error 40<uncorr>
...
THE FOLLOWING DISK SECTORS COULD NOT BE READ: 17, 18, 19, 20, 21, 22,
25, 29, 30, 31,
Floating exception (core dumped)
is there any way/tool to recover the data on the disk ?
Thanks
Luigi
