You need to check the "Western Digital" website and they have an excellent knowledgebase about these issues. Here's the link:
Western Digital Service and Support
And here are some links that might solve your problem:
Operating System and BIOS limitations - 137GB, 32GB, 8.4GB
What issues should I be concerned with when using a drive larger than 137GB (128GB binary)?
Hope this helps.
win2k does not "read" the whole 250 gb hdd (western digital 8 mb cache 7200 rpm), only 130 gb. The main board(bios updated) read 250 gb, heads cylinders ... etc, but not win2k, or partition magic 7.0 . I've tested an partition magic 8.0 (shareware), but nothing !!!
