Hi,
I tried to creat a RAID1 with 2x3TB TOSHIBA Disks following the thread:Create RAID 1 with existing Data Disk. But i did it very wrong and result the RAID not usable.
Before begining there was nearly 3TB data in /dev/sdc1. Disk /dev/sdb is clean and empty.
[*]I put the following code in my terminal
[*]Then I went to the webUI and did the RAID recovery in RAID Management page and added my /dev/sdb to the RAID.
[*]The RAID Management page is like this:
[/list] File Systems page is like this:
Here is the content of "fdisk -l" command:

Now the RAID cannot be used and I can't get access to my data. I need to recover the data can anybody help me.
Thanks!
