    I have a silly RAID question, and I can't seem to find an answer via the search.

    I have 4 disks that I want to put in a striped raid. One of those disks (disk 1) has data that I'd like to keep.

    If I put these 4 disks in the striped raid will I lose the data that is on disk 1?

    You NEED to backup the data. A software raid basically formats each disk as RAID, then it treats them as a single disk and formats that.

    One more important thing to note is that you want to backup the data no matter what. A RAID is NOT a backup solution, even if it was a RAID1.

    Thanks Dalton,

    I figured as much but I was curious if it could happen without a backup.
