|You'd remove the drive cable and power cable from the drive in the 95 PC. Then remove the screws holding the drive in the case and remove the drive.|
Then open up the other computer. You could either attach the 95 drive as a second (slave) drive on the same cable as the working drive in that computer or, if your cdrom(s) in that PC are on a separate cable you could disconnect that cable from them and attach it to the 95 drive.
The 95 drive doesn't need to be mounted in a bracket in the case. Since it's just temporary you can just leave it lying on the bottom of the case or wherever is convenient. Just make sure the drive's circuit board isn't touching the metal case nor the drive touching the motherboard or other electronics in the case.
If you attach it on the same cable as the hard drive in the working PC you need to pay attention to the jumpers Jumpers distinguish drives on the same cable so the OS can tell them apart. They're either jumpered MASTER, SLAVE or CABLE SELECT. If one is jumpered MASTER then it's normally the booting drive. A second drive on that cable must be jumpered SLAVE.
Or if the drive already on the cable is jumpered CABLE SELECT then a second drive on that cable is also jumpered as CABLE SELECT. When using cable select it's the drives position on the cable that determines how the OS sees it. Normally the drive at the end of the cable is the booting drive and the drive attached to the middle connector is the non-booting drive.
If you temporarily remove the cdrom cable and attach the 95 drive by itself there, the jumpers are probably irrelevent since it's the only drive on the cable.
So attach the 95 drive by one of the methods above and attach the power cable. Then boot up the PC. The OS should see the 95 drive in 'my computer'. If you detached the cdrom(s) and used that cable then obvioiusly they won't show. But of course that's only temporarily until you get things copied. Once that's done you'll remove the 95 drive and re-attach the cdrom(s).
Once you get to the OS desktop you'll have to find the files you want to copy and then move them to a separate folder on either the working drive or the lacie, if it's attached.
Once all that's done, shut it off and reassemble everything as it was originally.
The above works for IDE drives. Newer computer often have SATA connection, which are different. But even in those, the cdroms are often on a regular IDE connection.
