A while ago I removed the HDD from my home computer because the OS had corrupted and I have been storing it at my grandparent's house. I took it home today, and wired it into my computer, but when I started my computer and went to "My computer" to view the files on the other HDD, nothing showed up except the Harddrive I am using atm.
I would hope to find out how to open and use some of the files, because I have Microsoft programs that I dont want to have to repurchase on it. (I lost the key/disk for Punch Home Design, Word, Excel, Powerpoint, etc.

Id also like to use it as extra space since I'm running out. Iv had this current HDD for two years and already used up over 100 GiBs, although I can't find many programs that use more than 100 MBs. Including Blockland
