I have an 18TB hardware raid array where the drives are fine, but the catalog for the drive somehow got corrupted. I get the following message: OS X can't repair the disk "TCI." You can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can. I've tried every known tool to rebuilt it, but with no success. Therefore, I am attempting to copy everything off of it. However, my problem is that when I start copying data off of it, the Mac restarts itself about every 15 minutes. This makes it a bit painful to copy off 18 TB, when I can only copy about 50GB before it restarts. On restart, I get the message "Your computer was restarted because of a problem.". I know it's because of the drive, as this doesn't happen if I disconnect the drive. What I'm wondering is if there is any way to get it to stop restarting (i.e. ignore the catalog errors) long enough for me to get some data copied off. I'm not quite sure why it keeps restarting, other than that it's doing it to attempt to repair the volume. However, after it's auto-reboot, I always get the "OS X can't repair the disk" message. Again, there is nothing wrong with the drives. Appears to just be some data corruption, as some of the files sizes are wrong (unless they started making 255TB drives). Just wondering if there is some way to "suppress" the errors long enough to get the data off it. Thanks.
