Seagate ST2000DL003-9VT166

Following up my earlier post..

I contacted Seagate, and my initial call which went through to the US cll canter as it was late pm UK time didn't really get me anywhere, and we got cut off. I followed this up with a call to the EU support centre next morning. The copyright Sports-Alive/Gareth Jones there was very helpful (and reading between the lines I think this is now a known problem with Seagate) and suggested that he replace my three st2000dl003 drives. Not like for like, but effectively upgrading to a ST2000VN000-1h3164-500. These are the new NAS certify Seagate drives. Result, I thought.

They finally arrived from the NL yesterday, and I was slightly concerned that were refurbished drives rather then new. I immediately hot swopped one of the old ST2000del003 drives. The Ultra4 tested the drive, and then reported that the drive was too small to be inserted in the RAID array. :( I download the logs, and the drive, though marked as 2TB, is only 1.89

Device Model:     ST2000VN000-1H3164
Firmware Version: SC42
User Capacity:    1,897,998,934,016 bytes [1.89 TB]
Sector Sizes:     512 bytes logical, 4096 bytes physical

as opposed to the exiting drive info:

Model Family:     Seagate Barracuda Green (Adv. Format)
Device Model:     ST2000DL003-9VT166
Firmware Version: CC3C
User Capacity:    2,000,398,934,016 bytes [2.00 TB]

So, I'm a bit stuck here. To replace the drives I will need to backup all my data, remove the old drives, then insert the new drives and reset the config. Restore all the data (Though I only have approx. 4 Tb. And then presumably also install all my add-ons etc. I have since phoned Seagate again, and they said that was the capacity of the drive, and nothing could be done.

I didn't help that these forums were down all day yesterday...but now researching backup strategies, and how to restore the Readynas without giving me lots of grief. At least I'll have plenty of spare time over Christmas to tackle this....
