Disc from ReadyNAS NV+ (Raid 0)

#1 Post by RichardK » 25 Feb 2016, 22:32

Hi there,

After spending hours waiting, I finally I got result.
2 partitions found, 1 I can list and select files.
The second:
"Support for this filesystem hasn't been been implemented".

Eurh.. Found partition is Linux RAID, it should be supported?
The system is now running a deep search:

Any idea what I have to do now?

Richard

A raid0 partition is half a filesystem because the data is splitted in 2 partitions on different disks.
So even if TestDisk can list the content of an ext2/3/4 filesystem, it will not be able to list the content of the Linux RAID.

In your case, there should be probably several partitions named md0, md1, md2.
As you haven't copy the whole testdisk.log file, I don't even know if a partition is missing!

Sorry,

Had some problems getting a "good" logfile, but here it is:

interface_write()

No partition found or selected for recovery
simulate write!

write_mbr_i386: starting...
write_all_log_i386: starting...
No extended partition

TestDisk exited normally.

First partition I can list it, but the 2nd partition is a no go.

Regards,

Richard
