I purchased a NSLU2 and used Acronis 8 to save drive images to the NSLU2. When trying to verify the archive, it usually said it was corrupted, or you would get a read error. Purchased 2nd NSLU2, same problem. Purchased another type of drive enclosure. Same problem. After several weeks of trying different things, I resolved my problem by making a hardware modification to the unit. I disconnected the 33 MHZ crystal oscillator from the IXP processor (this is R123) and then jumpered the crystal input of the IXP to the 30MHZ crystal next to the NEC USB chip (crystal leg furthest away from the usb connectors). No more problems. Disclaimer: Any modifications you try are at your own risk. You will lose your warranty and may invalidate fcc certification.
