The drives on the re-scanned channel must not be in use (mounted, ioctl-operated, etc.). If you want to rescan sth on the first IDE channel, you must: - umount everything from /dev/hdax, dev/hdbx - swapoff -"- -"- -"- - use an existing drive from another channel in fopen(), eg. hdc
These are ioctl() limitations...
