If I have not given enough information or if another place is better to
ask, please let me know.
I have a QNAP NAS and I have replaced one drive because I thought I would
just plug in the HD in my machine, boot it and mount the device.
I have done so in the past, but now it does not seem to work anymore.
This due to the fact that drives are now standard in RAID and not just
ext3 or ext4 anymore. I removed the drive, because the other drive that
contained the same data failed. So I had the data twice on two separate
drives and now I have none. Just adding it to the QNAP does not work
either.
I would like to be able to mount /dev/sdc3 and retrieve the data.
I run Debian GNU/Linux 8 (jessie)
Here is some of the output:
root@penne : fdisk -l /dev/sdc

I have removed and added it with
root@penne : mdadm --manage /dev/md124 --stop
mdadm: stopped /dev/md124
root@penne : mdadm --assemble /dev/md124 /dev/sdc3
mdadm: /dev/md124 has been started with 1 drive.
All to no avail.
I have searched the past week and am not able to figure out how to mount
the partition. Any help would be appreciated.
