plz help ... huge problem when upgrading to windows 7

I see your fujitsu drive is what failed. Try the Fujitsu Diagnostics. It will give you the error code you need. Let the test run to completion. It might take over an hour and I suggest you stay near the computer or check it every 10-15 minutes while the test is running.

EDIT: If your having the problem I did, reformatting only makes the problem worse. You put stress on the drive will formatting and a failing hard drive will only fall into further decay. Also, I know the link says Toshiba. They purchased the part of Fujitsu that made hard drives.

He posted a link to a screen shot of his seatools result. It showed a Fujitsu mhy2250bh that had failed the test. The link is within post #28

Replace the drive...

Contact you OEM. I got the same result and Dell was quick about sending me a new hard drive. I don't know how quick Sony is, but if they know what they are doing, they will go ahead and replace it.

If you got that error code, it needs to be changed. At least HDD disk that aren't too large are dirt cheap right now. If the don't replace it invest in a new one. If you live in the USA, Newegg has 250GB hard drives starting at $45, but I recommend getting one a little more expensive then that.
