A while ago I read somewhere, that it was possible to swap hard disks in a PS3, thus having several disks with OFW installed that you could then swap between. Unfortunately, trying that out caused all hard disks to not be readable anymore, and no matter what HD I put in, I'd be told at boot that I'd have to reboot or reinstall the firmware. After that, I looked up how to recover data from a PS3 hard disk. I've installed CFW on a new disk, extracted my PS3's eid root key, and used PS3 HDD Reader to make a backup of all the folders on one of my disks. Then I installed OFW on a separate disk and now I have a basic installation, that I can read using HDD Reader. But that software only reads, but doesn't write. So my question is, how can I write the backed up data I got from an old hard disk, onto this new installation and can I just copy it all, or must I only copy select folders?
