ibm harddrives are now Hitachi.
go to http://www.hgst.com/hdd/support/download.htm#Drive%20fitness and download the windows or linux diskette creator for Drive Fitness Test.
read the instructions.
use the progtan to create a bootable diskette that contains Drive Fitness Test.
drive fitness test has an erase disk utility that writes zeros to the hard disk.
be sure to follow the instructions exactly.
be sure you are testing the hdd you want to fix!!!
after you erase the disk, partition and format the hdd as usual and install your os.
have fun
