I've got a used 30gig Maxtor I'm using as Primary-slave for storage and backup files only. I've partitioned and formated the drive using XP Admin tools as well as Maxblast. I can copy files and folders to it and access them without a problem, but after a few days I get "drive not accessable" or "data invalid" or if I can access the drive, some of the files are missing. If I repartition and format the drive again, it works ok for a few days. I'll probably just scrap the drive, but I've never run into this before. Any ideas?
