Do I back up my main SATA boot drive with a cheaper PATA HD and using the SATA converter? Or do I just suck it up and buy an identical SATA HD and be done with it (which would mean paying a little more up front, around $30-$50 more) because the deals can be had on the PATA HD each week. The other thing that I wish I knew was whether or not Maxtor or Western Digital 120GB had the same amount of sectors on them or if the WD had more sectors (which would allow me to ghost the Maxtor onto it without any problems, otherwise, if the WD had less sectors, I couldn't ghost the entire HD from the original Maxtor to the WD backup HD). I have a WD 120GB still sealed in the box ($60 after rebates), but I don't want to install it and find out the sector count is less than a Maxtor HD. The Maxtor sector count was the same for either the SATA version or the PATA version. ---- FYI: I did do a test with ghosting my Maxtor 120GB SATA boot HD onto a Maxtor 120GB PATA HD (used to backup my other 120GB drive in another PC). I used a Highpoint Rockethead 100 SATA/PATA adapter with the PATA HD and connected it as a SATA HD to the motherboard's SATA controller. The test was successful as I was able to boot up the PATA HD with the SATA adapter in place, and XP booted up with no problems.
