I'm having a notebook which has a Seagate Momentus hard drive. Now the problem is that when i turn on my system, it boots to Windows Xp, it automatically runs the scandisc and then it reboots my system. But when i try to cancel the scandisc test, my pc gets freeze up. Now the problem is that when i try to format my hard drive, it gets stop on the end of formatting process stating an error message " partition magic - error ". Can any one tell me that why i'm not able to format my hard drive? Why i'm having problem with my Seagate Momentus hard drive? Any one knows about it? Please help me to resolve the above issue. Thanks.
