Myth could play them, or at least start playing them - I don't know if it could get to the end of any of them, but if I tried to copy them off to another drive the machine just started hanging with lots of dmesg drive errors. None of the previous windows backups were savable. I've taken new windows backups starting last night. The failing drive is now off line and the family will just have to live with less Myth recording time. I've switched to an old, slow 80GB 1394 drive vs the newer 160GB USB2 drive that failed. I guess this now comes down to having no backup for my backup system. ;-) Saving anything on hard drives always results with this risk I suppose. My daily backups are 1-2 GB in total so I guess I could start writing DVDs or something like that. Thanks to all for your inputs and ideas. Cheers, Mark
