Hi,
I have tried what you suggested.
I tried "dd if=/dev/hdX of=/dev/null bs=4k" under kernel 2.4.3 and got:
dd: reading `/dev/hda7': Input/output error
32792+0 records in
32792+0 records out
After doing this I got the following error with dmesg:
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x40 { UncorrectableError }, CHS=10793/1/175,
sector=262336end_request: I/O error, dev 03:07 (hda), sector 262336
This was the only disk error and it was there only after the "dd" command.
--- The same "dd" command under kernel 2.4.17 gives a similar error message although with a different record number.dd: reading `/dev/hda7': Input/output error 32772+0 records in 32772+0 records out
The errors from dmesg are below. The "VFS: Disk change detected on device ide1(22,0)" error was there before the "dd" command, and it shows continuosly:

It is also interesting that with kernel 2.4.3, I only get one error from using the "dd" command. The drive makes some noise and then it stops with the error above. Under 2.4.17, it seems that it tries harder and I get more errors. The drive stays there making noise. (BTW, the noise is a set of 4 x runck plus 4 x ham! It seems each set corresponds to an error on dmesg.)
Also, I do not really understand what the error "VFS: Disk change detected on device ide1(22,0)" means.
The results point to a damaged disk, however, it is still interesting that this is not detected by e2fsck under the 2.4.3 kernel. After doing the "dd" command and getting all this errors, I have checked the filesystem again with similar results. It is "clean" if running kernel 2.4.3!
Thanks, -Joao
