HP PC HardwareDiagnostic Windows tool/app. Does anybody know this tool or app? I ran the Fast Tests included inside of it last week and it stops at #3 or #4 and reads Disk1 FAILED. That's it no explanation, details nothing. I ran the Windows Disk Version of the same thing and Disk1 all parts are fine. Today for the second time I re-downloaded the tool and ran the Fast Tests again it stopped at Disk1 Failed claimed it had to close for an unknown reason and crashed. Has this happened to anybody else who uses this if anybody else does use this? I can't get an answer anywhere on Hp.com and would rather not have to wait two or more weeks for a simple answer.
Thank You.
