1 of two drives failed in my external, but I can't access the one that is OK...

[drummerboy03]

I had two 1.5TB drives in an OWC enclosure. I had it formatted as 'Mac OS X Extended (Journaled)' so that it showed up as one 3TB volume when it was mounted.

One of the 1.5TB drives failed yesterday (makes a loud noise when trying to spin up). I suspect the other 1.5TB drive is completely fine as it does not make any odd noises when I remove it and plug it into a single HD slot enclosure.

the problem I'm having now is that I cannot access any of the data on the 1.5TB drive that I suspect is OK...... it does not mount, but it DOES show up in Disk Utility. When I try to verify or repair permissions, i get the following error:

"partition map check failed because no slices were found"

I even tried Disk Warrior, but the drive does not show up in the list.

any help would be GREATLY appreciated!! thank you!

Your RAID 0 stripe set is unrecoverable.

Hope you had a backup.

When one of my drives in my owc enclosure failed I sent it back to owc and they replaced the drive. When it got back to me I could see all the files on the good drive but all files on the failed drive disappeared and were lost.

In my case I had purchased the drives with the enclosure, so it was under warranty.

dangit...

I had backed up all the raw GoPro video footage recently, so i at least have that... but i had spent hours editing down that raw footage in an iMovie project that was stored on that drive ;(

was hoping there would be a way to recover some data from the 1 working drive, but it sounds like with RAID 0, it is distributing the data across both drives.

so i'm for sure out of luck? in other words, i should cut my losses and reformat the 1 drive that still works and start to rebuild my life haha?

thanks for the quick response/input!

Yes, that's your only choice.

First though, go get a 3TB-4TB USB drive and set up Time Machine.

Remember RAID is not a backup.

RAID0 and Spanned Drives always need a backup as any failure destroys the whole structure. RAID1 does provide resilience against a single drive failure, but it also isn't a backup. IMO get a simple USB drive and make a mirror. Even Time Machine will fail as it's only a single drive.

RAID _is not_ a backup.

Be governed accordingly, in the future.

Live and learn...
