Question 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

MKFS.MINIX(8)						Linux System Administrator's Manual					     MKFS.MINIX(8)

NAME
mkfs.minix - make a Linux MINIX filesystem SYNOPSIS
mkfs.minix [-c|-l filename] [-n namelength] [-i inodecount] [-v] device [size-in-blocks] DESCRIPTION
mkfs.minix creates a Linux MINIX file-system on a device (usually a disk partition). The device is usually of the following form: /dev/hda[1-8] (IDE disk 1) /dev/hdb[1-8] (IDE disk 2) /dev/sda[1-8] (SCSI disk 1) /dev/sdb[1-8] (SCSI disk 2) The size-in-blocks parameter is the desired size of the file system, in blocks. It is present only for backwards compatibility. If omit- ted the size will be determined automatically. Only block counts strictly greater than 10 and strictly less than 65536 are allowed. OPTIONS
-c Check the device for bad blocks before creating the file system. If any are found, the count is printed. -n namelength Specify the maximum length of filenames. Currently, the only allowable values are 14 and 30. The default is 30. Note that kernels older than 0.99p7 only accept namelength 14. -i inodecount Specify the number of inodes for the filesystem. -l filename Read the bad blocks list from filename. The file has one bad block number per line. The count of bad blocks read is printed. -v Make a Minix version 2 filesystem. EXIT CODES
The exit code returned by mkfs.minix is one of the following: 0 No errors 8 Operational error 16 Usage or syntax error SEE ALSO
mkfs(8), fsck(8), reboot(8) AVAILABILITY
The mkfs.minix command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/. Util-linux 2.6 2 July 1996 MKFS.MINIX(8)
