We're trying our very best to help you but you're not making it easy.
You're so hell bent on getting that drive to work that you're blinded by the better alternatives.
Yes you have hundreds of games on disc, yes ripping that isn't really an option.
Did you ever think about disc rot? that will set in on recordable DVDs and when that happens, your discs will be toast and you've got no way to recover then other then to redownload and start from scratch.
godreborn and I have suggested everything we could suggest, no we're not judging you, we're simply giving you options of what you could do with your RGH.
Just bin the drive, dump a 2TB drive in there and get over it.
But hey, don't listen to me or godreborn or others, enjoy wasting your time and money which you could've used and spend on playing games on the thing instead :')
You want a real piece of advice? be open minded about alternatives suggestions.
Or you know, give up and bring the thing to a specialist, we couldn't care less.
