Second, it hasn't been possible to do a real low level format of a hard drive since IDE first came on the scene. A true low level format requires equipment only the manufacturer has.
Oh, I did not know that, the problem is that "My intention was to replace an older 50GB HD with a new 500GB HD in a system running WinXP. Using R-Drive Backup, I created a backup of the old drive as a file on another HD added to the system. And then, I partitioned the new drive into one 50GB (for the system) and a second using the space remaining. I set the 50GB partition as primary - and (after reading something on the Net), decided to set the primary partition as active. But after that if I place the new drive in any system, during the startup when the BIOS detects the new drive (before the boot process is started), the system stops. So I would like to reformat the new drive and start over, but I dont know how to get rid of this problem. NOTE that once I connect on this disk the computer could not boot up. Do you have and advise? Thanks.
