Drive not readable

Postby JamesLip » Nov 7th, '13, 02:59

Hi there

I was wondering if someone could help me

I have 12 TB ES Pro attached to a Mac pro using a R680 in raid 0

It has been working fine for about 9 months but yesterday when I to restarted the machine it, the drive didn't come up and "The disk you inserted is not readable by this computer" message came up, i have tried restarting a few times it always comes up with the same message. All the lights are blue and when i log into the Atto config everything seems fine

This has happen once before on the drive around 9 months ago and then the data wasn't so important for just re-formated the drive now i really need the data back so if there anything anyone can suggest i would be very grateful

Cheers

James

Hi James,

Thanks for posting. It sounds like there was some corruption to the partition table to the point that OS can't see the partition data. A third party program will be needed to recover the data. In this case I would recommend either Data Rescue 3 which bypasses the partition table and allows you to get the data off, you do need another drive capable of holding the data on it however. Another program that I have gotten feed back form that worked well specifically on the g-speed series is r-studio. Good luck.

Ok Bugger so not a simple fix

I've looked a data rescue and it looks to only restore know files, we use a lot of filme files like MXF and Ari files and it appears to rename or move the file structure

Do you think there a fault with a drive ? We use quite a lot of ES pro around 12 this year and this is the only one that failed and it done it twice ?

Cheers

James

James,

Corruption can be caused by external influences like power surge improper disconnects, programs locking up while accessing the drive, and a variety of other things. If it was within a month or so between corruptions I might worry but 9 months I wouldn't say so. You can try turning the unit off, ejecting each drive and reinserting it as sometimes the modules can wiggle a little loose from the cumulative vibration of the array.
