exFAT drives suddenly changes to MS-DOS - not readable

[Phillipjacob]

hey all..


I need some help regarding external hard drive, more specific LaCie 2big 12 TB hard drives.

The problem is that we are formatting them to run as ‘exFAT’ but suddenly it stops working and says it is formatted as ‘MS-DOS’. We can’t mount the drive on any mac computer nor windows.
We’ve tried to repair in disk utilities etc. but nothing seems to work.


We’re using the hard drives to movie projects and using ‘Avid’ to cut in.
It is a mac environment and there are a lot of huge files running back and forth.
and we're running with raid 0.

I’m open for suggestions and guidance.

Phillip

Why are you formatting them in exFAT instead of HFS+ ? If this is a MAC environment, use the MAC native file system. Those devices come factory formatted in HFS+ ....

I would start by examining sectors 0, 1 and 2 with a disc editor. If you have access to a Windows machine, you could use DMDE (freeware):

Yes we should have used HFS+
We used exFAT because we had to move between mac and windows, but even that shouldn't be a problem with the correct software.
But from now on it is HFS+

Okay, thanks. The disk is right now running a recovery program, but after I'll try DMDE.

Thanks.

It says I have to pay to recover my files.

DMDE is limited to recovering 4000 files, but the disc editor is fully functional.
