I have two PCs,an older Pentium III with PATA HD, and a new PC with SATA. I've had the occasion to use TI8 and TI9 on both computers. I've restored the P3/Pata twice because of trojans( ^$%& NAV2005!), with no problems. I got one the frequent WinXP blu scrns of death on the new computer, only the last time. I couldn't reboot. I tried a restore TI9 2302, only to discover a corrupted backup. Luckily, I keep critical files/programs on DVD's, so no major problems on a manual format/restore, except 1 1/2 days involved. I'm convinced the combo of SATA HD/WinXP is very unstable.
