    I'm having a problem with my external RAID that I use between my G4 Laptop (10.5.x) and G4 tower (10.4.x).

    I downgraded the G4 laptop to 10.4.x so I can run Classic (kids educational software), and gain some speed.

    I backed everything up to my external RAID (two HD's RAID together).

    The downgrade install onto the laptop went perfectly.

    I went to restore some files from the RAID backup, and I got this error when trying to mount the external RAID: "the disk you inserted is not readable by this computer"

    I just ignored the error and DID NOT TOUCH the RAID.

    I then re-connected the RAID to my G4 tower that had previously mounted successfully, and same error: "the disk you inserted is not readable by this computer".

    This time I started Disk Utility, and it sees the RAID and it's volume set, but it is "LOCKED" (see attached pics).

    I think I need to FIRST mount it to change any "access control list" or permissions, but I can't figure out how to mount, and then change permissions/ACL.
