"DataRequest Error", e2fsck, badblocks, etc.

Greetings,
I recently started having those infamous "DataRequest Error" messages
on my /dev/hda:

hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=6703451,
sector=98972
end_request: I/O error, dev 03:07 (hda), sector 98972
hda: read_intr: status=0x59 { DriveReady SeekComplete DataRequest
Error }
hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=6710665,
sector=106186

I checked to see which partition these come from:

~> /sbin/fdisk -lu /dev/hda
       Device Boot    Start       End    Blocks   Id  System
    /dev/hda1            63     40319     20128+  83  Linux
    /dev/hda2         40320   7814015   3886848    5  Extended
    /dev/hda5         40383   3322367   1640992+  83  Linux
    /dev/hda6       3322431   6604415   1640992+  83  Linux
    /dev/hda7       6604479   7136639    266080+  83  Linux
    /dev/hda8       7136703   7668863    266080+  83  Linux
    /dev/hda9       7668927   7805951     68512+  82  Linux swap

and it looks like /dev/hda7 is the problematic area (I know I have to
replace the entire HDD, but until I buy it I would like to see what I
can do to keep the system running).

/dev/hda7 was mounted on /var, so I moved /var to somewhere else,
unmounted /dev/hda7 and did:

~> /sbin/e2fsck -pc /dev/hda7
/dev/hda7: 17025/66528 files (5.5% non-contiguous), 127766/266080
blocks

I expected to be prompted by e2fsck to fix errors, or at least
*report* some errors. Instead, it displayed a single line, which I
interpret as "everything is OK". What am I missing here?

I also tried:

~> /sbin/badblocks /dev/hda7 266080
56664

56664 is the only output from badblocks, which I interpret as block
#56664 from the start of /dev/hda7. (am I correct?)

Can someone please explain why this discrapency and what am I missing?

Many thanks in advance,
L.L.

You should really learn not to multipost.

I followed up to this in another group.

1. kernel error "DriveReady SeekComplete DataRequest Error"

Greetings,

While grepping out for terms in my web log files the following error
messages showed up in my /var/log/messages file:

Aug  1 00:01:34 brama kernel: hdb: read_intr: error=0x40 { UncorrectableError }, LBAsect=7357944, sector=7357881
Aug  1 00:01:34 brama kernel: end_request: I/O error, dev 03:41 (hdb), sector 7357881

Any advice in understanding and remedying this would be greatly appreciated.
