Probably this wasn't supposed to happen, was it? I had bought a new 500 GB SATA disk to be built into my PC. To copy the boot partition I attached it to the PC using a cheap SATA-via-USB connector. Probably you have seen these devices on Ebay before. Its a strange socket to be plugged into the back side of the disk, providing both IDE and SATA. It also includes an external power supply. Creating a partition table and copying the boot disk went fine. After that I replaced the internal disk with the new one, fixed the mbr and tried to boot. It worked. Next I mounted (rw, shame on me) the old SATA disk via USB to the PC, and tried to copy the data. But during the copy there were some syslog messages about file system corruptions on the old disk. I stopped rsync, unmounted the disk, and ran fsck, but it was damaged beyond repair. No chance to recover any data. The question is what has happened here? I checked the old disk on a real SATA connector; it seems to be OK. ??? Regards Harri
