Repair HDD with approporiate partitioning
Hi gurus, this is non standard linux question but I thing linux could help with this 
I have HDD (Samsung) which contains bad sectors (or clusters/blocks - dont know exact terminology). I downloaded official software for diagnostic (bootable CD with free DOS and utility) - and I executed low level format. BUT it returns me LBA (I am little confused with LBA) address which contains bad sectors.
My question is: Is possible to locate bad clusters and then make partitioning excluding those part of HDD which contains bad sectors ?
Example (The values are think out not real numbers):
lets say 160 GB HDD has addresses of lba from 0 to 160000 LBA
now lets say that at 120000 LBA is some bad cluster
so i wuld like to create 2 partitions from 0 - 110000 LBA and from 130000 LBA - 160000 LBA
so lets say sizes of partitons would be 110 GB and 30 GB.
I hope I explain clear what I am achieving. - Could you please point me to some tutorial or something like that.
Thanks a lot
