There seems to be some terminology conflict in your message but I think you are saying that you have put a hard drive from an old computer into a new one, right? and the old was had two partitions, right? Can you read part of both partitions on the old drive and what kind of files are missing? What OS is on the old drive? Have you enabled XP to view all files and not hide extensions? Such information might be helpful but there is never a guarantee that adding such a drive with existing data to a newer rig will go smoothly. Post more details if possible.
Bought a new CPU & an removed a 120GB Hard Disk which was C:\ & D:\; which now became D:\ & E:\.
Drive C:\ is the HD in the new CPU. My problem Is that I had some files on the old disk that don't show up any more?? I have know idea where they have gone.
Is there any chance of recovering these lost files?
Also in my MSWorks V.6 I have some files that have an extension of: TZ3 that I can't open...how can I open them? I did not create the extension!
