I attempted to clone a WD EIDE disk to an identical, blank replacement disk after getting an incipient SMART failure report. TrueImage seemed to run correctly and completed all three phases successfully. There were no error messages of any kind. However, the new disk did not work and further investigation showed it to be blank, consisting only of unallocated space. I attempted a second run using the add new disk wizard under XP (SP1). This also ran to an apparently successful conclusion. However, the new disk still did not work properly. This time the computer booted from the new drive and the XP startup screen appeared, but the Welcome screen never came up (though the mouse remained active). I then booted from the original source disk with the new disk as a slave. The 2 partitions displayed in Windows, but both were deemed inaccessible. Next I booted from an NTFS-DOS floppy. I was able to see all of the directories and files in both of the new drive's partitions! So I again tried to boot from the new drive--without success. I ran Spinrite and got an error message that no compatible hard disk was installed (untrue, and the disk WAS recognized by the BIOS). Next I tried Partition Magic, which displayed a "demounting" error and refused to proceed. At this point I gave up, repartitioned and formatted the drive, and began the torture of reinstalling XP and all the apps from scratch. Can anyone tell me what's going on here? I have become very uncomfortable with this product.
