i dont usually like following up my own sensless ramblings, but here is an
interesting twist (probabally caused by my ill understanding of the issues
involved)

ive done the badblock test, and compiled a list of 2302 bad blocks on this
disk ... however, when running mke2fs -l badblocfile /dev/hdc1

i got this interesting errormessage for every one of the bad blocks :

Bad block 1006290 out of range; ignored.

mke2fs said my disk was my disk would be 132480 inodes, 264592 blocks in
size ...

some bits in proc (well this capacity one i dont know what it measures)

root:/root# cat /proc/ide/hdc/capacity
2116800

root:/root# cat /proc/ide/hdc/geometry
physical 2100/16/63
logical 525/64/63

is there a geometry problem ? whats causing bad blocks to give apparently
excessivly large bad blocks ...?

any ideas ?

Thanks,

Dave
