Repair HDD with approporiate partitioning

Hi gurus, this is non standard linux question but I thing linux could help with this Smilie

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

isosize

ISOSIZE(8)						       System Administration							ISOSIZE(8)

NAME

       isosize - output the length of an iso9660 filesystem

SYNOPSIS

       isosize [options] iso9660_image_file

DESCRIPTION

       This  command  outputs  the  length  of an iso9660 filesystem that is contained in the specified file.  This file may be a normal file or a
       block device (e.g. /dev/hdd or /dev/sr0).  In the absence of any options (and errors), it will output the size of the iso9660 filesystem in
       bytes.  This can now be a large number (>> 4 GB).

OPTIONS

       -x, --sectors
	      Show the block count and block size in human-readable form.  The output uses the term "sectors" for "blocks".

       -d, --divisor number
	      Only has an effect when -x is not given.	The value shown (if no errors) is the iso9660 file size in bytes divided by number.  So if
	      number is the block size then the shown value will be the block count.

       The size of the file (or block device) holding an iso9660 filesystem can be marginally larger than the actual size of the iso9660  filesys-
       tem.  One reason for this is that cd writers are allowed to add "run out" sectors at the end of an iso9660 image.

AVAILABILITY

       The  isosize  command  is  part	of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils
       /util-linux/>.
