I have a pc that Dual boots win 7 and ubuntu. When in ubuntu, the os crashes and gives some error about hdd has i/o bad block errors but scans reveal no problems. I have used the WD scan tool several times and it always says the hdd is fine. The win 7 os has issues, too it seems. There are i/o errors in Event Viewer. Is this hdd crashing, or is there some other issue since the WD tools don't find anything.
Any help is appreciated.
