It's a "store bought" Sony VAIO desktop PC and the other HDD is fine. Would you happen to know if Sony's power supplies were prone to being flaky? I have so much surge protection on everything I don't think it's that. Regards, Keith.

Agreed. But so far the disk has no bad sectors. Might be something else entirely... Arno

Might be premature. So far the disk has no defective sectors, just some it has trouble reading. This may have other reasons, which could influence a new disk just the same way. You can of course get a new disk and try, but it is possible that it will show similar symptoms. Arno

Not sure what to do now, probably will try a new one and see how it goes. Regards, Keith.
