My Toshiba SD-H400 has been crashing a lot lately, and now it won't boot at all. I have power cycled it many times, but when I try to power it up now I get the "Welcome, powering up..." screen for about 30 seconds and then it gets stuck on the "Almost There. Just a Few Minutes More..." screen indefinitely. Reading through the forums this seems to be a very common problem with the SD-H400, almost always attributed to a bad Maxtor hard drive. I've gotten 3-4 years of life out of this unit, and I'm willing to invest in a new hard drive if that will fix the problem. I tried following the "kickstart" instructions from another post, but couldn't get the hard drive diagnostics to run. My questions are: 1) How can I definitely confirm that the problem is just the hard drive? 2) If I do have a hard drive problem, is there any way to fix it, or should I just replace it?
