I have a series 3 (OLED) TiVo that was having some issues. Fixing a power supply bad cap seemed to only temporarily fix it. I replaced its hard drive with a 500GB one and was finally able to put its original 250GB hard drive in a desktop and ran the Western Digital Data Lifeguard Diagnostic utility on the entire thing. Did the "extended" test (took about 90mins). It came back with bad sectors and I chose the option to repair them, but it was unable to. I then ran the report and it says the following: TEST ERROR CODE: 08-Error was detected while repairing bad sectors. Does this pretty much mean the drive is not useable for TiVo purposes? OR can I possibly "write zeros" and this will fix it? Nothing important on here so I don't mind losing it all.
