So, sorry for the post. I KNOW this information must be in here, but now after 30 minutes of searching and reading I can't really find a specific answer. H10-250: dual drive, relatively recent PS replacement, had the temperature issue. Came home, device showed Powering up. It appears it was stuck. So, tried rebooting, but nothing, powering up only. Shut it down, check connections, plug in, nothing. Is there a way to tell if this is the primary drive or the power supply? The drives SEEM to be spinning or at least getting power - last time when this failed and had the temperature issue, the drives were clearly not getting power. I found SOME information about testing the drives (I assume the primary drive needs testing?), with maxtor/seagate/WD software, but there isn't really any summary of HOW to test? Does it have to be windows XP still or DOS only? boot into a linux distro and connect the drive/s with a USB to IDE connector? What am I testing for, bad sectors? If there ARE bad sectors, do I let the drive manufacturer software repair (ex-out) the bad sectors or will the kill the special tivo/linux install? Any way to get kickstart to work from a boot up? or is that only if the device is operating but not functioning? And if KS is possible, what is the process for an HDTIVO? Thanks for any responses or direct links? Maybe my ability to build the best queries is lacking.
