Advertisements My Sony SAT-T60 is stuck in a re-booting loop. I've tried unplugging the unit for awhile but the loop remains. What is the best way to diagnose the condition of the hard drive? Can I connect it as a 2nd HD to a Windows PC, and then run chkdsk? Will this utility even work with a TiVo-formatted HD? Or, can I download a program from the HD manufacturer's website and use that? Lastly, is there a program specifically designed to "check the disk" of a TiVo hard drive? Any feedback is greatly appreciated. Thanks!
