EXFAT raid 0 recovery

#1 Post by tomtailford » 12 Nov 2015, 21:41


GRAID 8TB (2x4TB striped raid) - EXFAT - showing up as RAW in windows / not showing partition in mac (only device)

Testdisk detects EFI GPT partition

Analysed - showed correct partition name (Chimp)
List files - showed all my files
Backup - saved current pariton list to backup.log file (not sure where this is on a MBP?)
Wrote partition structure to disk (thinking it would fix)
List files - "support for this filesystem hasn't been implemented"
Says MacHFS? (Confusing as 99% sure it was exfat)
Backup - saved current partition list as follows:

Code: Select all

#1447360813 Disk /dev/sdc - 8001 GB / 7451 GiB - CHS 972792 255 63
 1 : start=       40, size=   409600, Id=00, P
 2 : start=   409640, size=2742337456, Id=00, P
Please tell me I've not royally screwed myself :/

Run "cmd" (right click run as administrator) and "chkdsk /f d:" (replace d: by the correct drive letter).
