esata expansion faild

[msth]

Hi, i've got an RN104 with four 2 TB Harddisks.

I tryed to attached my Lian Li eSata Raid (5 x 3TB) via esata. And the ReadyNas has made anything with it. Now it's faulty.

When i attach the LianLi Raid to an Linux Machine, i see following

Modell: ATA Lian Li H/W RAID (scsi)
Festplatte /dev/sdb: 23441702912s
Sektorgröße (logisch/physisch): 512B/512B
Partitionstabelle: gpt

Nummer Anfang Ende Größe Dateisystem Name Flags
1 64s 8388671s 8388608s RAID
3 9437248s 23441702877s 23432265630s RAID

Can anybody tell me what the ReadyNas has done ? And how i undo this ?

Thanks

The ReadyNAS is going to format it for its own use. At minimum, it has a new partition table on it, worse it could have erased all existing data on the drive already.

On your Linux system, maybe try running something like http://www.cgsecurity.org/wiki/PhotoRec against the disk, to see if it can recovery old data.
