Hi Howard, Feel no pain! With the variety of hardware and OS's out there, someone is always going to have a problem. :) I have FAT32 on my C drive, my boot and applications partition. I thought I had formatted it to NTFS when I put XP Pro on it but apparently I did FAT32 for some reason. I wonder if it is possible to convert to NTFS and retain everything. I REALLY don't want to have to rebuild that drive again although it isn't that big of a deal, I've done it enough times in the past. Therein lies my problem with PBooost undoubtably, eh? Steve.
