I've replaced a few out of satellites too... I think they (toshiba's) are just junk in general. They have an incredible amount of crap software, for one thing. They barely run straight out of the box. The last guy had toshiba replace the first one and it failed. I told him it was in warranty, and to send it back in. He was so frustrated, that I sold him a seagate hdd w/ a 5 year warranty. I put vista back on it, but a clean version, devoid of the bloat.
