Isolating faulty sectors?

Hi,

Before I start I should mention that I KNOW this harddrive probably isn't far from death and whatever data on there is vulnerable...

I use a 500gb seagate on my media PC, doesn't do much holds an OS and AVI's/MP3's etc and plays DVD's... If I run checkdisk, sea tools etc i get errors, sea tools is unable to repair or isolate the damaged sectors, check disk just hangs, and spinrite hangs for hours upon end...

The reason i knew my drive was dying is that randomally, and i mean randomally it would give out a high pitched whine which a reboot and wait for 10seconds would cause...

Now I have accepted that those sectors are gone... but... does anyone know of a way that I can isolate the sectors/section of the drive so I can partition around it?

I.E if I know that sectors 3000-4000 is faulty which in theory could translate to sections 100gb-200gb of the drive then i could just tell fdisk or partition manager to use the 1st 100gb and job done.. or even create a spare "faulty" partition...

Hopefully i've explained clear enough and someone will have a solution or idea!

Thanks in advance,
Alex.
