When replacing builds and drives here I run right into losing a few downloaded programs if not backed up on removable media or a drive set aside strictly for storage and backup. I've seen where data disks on some occasions like data dvds and cd-rs lost file intregrity and lost files in the process of copying them onto a new drive or simply between folders on rare occasions.
When using any disk imaging software for backing up a drive always verify the integrity of things following the creation of any images to avoid loss there. Software disks on the other should always be stored in a safe place to prevent damage or misplacing them like you probably saw there.
I still have a load of floppies with WIN 95 files hanging around here all these years!

Don't feel bad I have to replace an old 5gb drive with an 80gb model on an old Dell system that saw 98! Try that without anything and not knowing if driver updates for 98 and that old of a system will be available.
The aunt that gave that to a nephew thinks that the original disks will work on a brand new laptop seeing XP by request or Vista. That included the cd for the board drivers as well. ddaaaaa.....
