hi guys,
        Since its relativley quiet at the moment, please excuse me for
asking for some advice about the following problem.

for a while now ive had a disk that causes errors to occur during reads,
however, ive finally got round to doing a

# badblocks -c 32 -o mybadblocks  -w -v -s /dev/hdc

so after one part of the test its found 2048 bad blocks, and dumped alot of
error messages, which look like this:

kernel: hdc: read_intr: status=0x59 { DriveReady SeekComplete DataRequest
Error }
kernel: hdc: read_intr: error=0x01 { AddrMarkNotFound }, LBAsect=2116604,
sector=2116604
kernel: hdc: read_intr: status=0x59 { DriveReady SeekComplete DataRequest
Error }
kernel: hdc: read_intr: error=0x01 { AddrMarkNotFound }, LBAsect=2116604,
sector=2116604
kernel: hdc: read_intr: status=0x59 { DriveReady SeekComplete DataRequest
Error }
kernel: hdc: read_intr: error=0x01 { AddrMarkNotFound }, LBAsect=2116604,

i have tried the disk in 2 systems, one Socket7 pentium and a PII /w a BX
chipset ... the only thing i can think this is is either a geometry problem
?? or a hard disk failiure ...

anyone got any ideas ?

Thanks.

Dave
