It works randomly off and on. When it doesnt work (which is 80% of the time Ive tried), XBox Backup Creator hangs when it tries to read the disc. After a couple of minutes the system unfreezes but I still cant backup the disc, its just greyed out. Ive changed IDE channels, changed it from Master to Slave, etc. but its still doing this to me. Been searching everywhere but seems that Im the only one with this problem. It reads other media fine, like DVDs, and even Backed Up XBox 360 discsm but wont read my original XBox discs. Also tried Schtrom and it says its not an "valid XBox disc". When it does work, it makes flawless backups. Ive reflashed the Kreon .81 but still the same thing.
