I don't think it will do any harm to have both installed, though.

What is the partition type on /dev/hda1 and /dev/hdc1? If they are not both FD (Linux raid autodetect), your raid array won't work. Note that, if you have data on /dev/hda1 that you want to keep, you should mark that disk as a failed disk. Then, when you make your raid array, data won't get erased from /dev/hda1. You can then mount the disk and the raid and copy the data from one to the other. Once your data is on the raid, mark the /dev/hda1 disk as a live disk, and the raid will re-sync, and your data will be intact. If the partition type is not causing your problem, let us know and we'll try something else. Justin Guerin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
