I have 2 drives on my PC. A 120 gig master, an 80 gig slave that I use for storage of files primarily. My question is, is there a way to disconnect the slave ( I want to put in a new one ) and still maintain whats on the disks ? Or, should I move everything ( the stored files ) to an external HD and if so, how long will that be good for. There are muy gigs of files that I don't particularly want to copy to disk.
