Ready NAS Duo RND2000 new drive not recognised
Hi, I have had a Duo RND2000 for about 5 years now running with 2 x 2TB Seagate Barracuda drives. Disk 1 started to show ATA errors and seemd to be causing issues so I bought a new replacement d...
If you purchased 5 years ago you have a duo v1 (which would run 4.1.x firmware). That does NOT support GPT formatted drives, so it is limited to <= 2 TB. There is no workaround. So if you need more space you'd need to get a new NAS.
Tthe RN102 is the equivalent product in today's lineup, and is quite a bit faster then the duo. If you are interested in media streaming, I'd get the RN200 or better though. The higher end platforms support real-time transcoding, which is often needed.
FWIW There are a lot of posters here who have had trouble with DM drives. For the v1s, I suggest the WDC WD20EFRX. The Seagate ST2000VN000 is another possibility - though I don't recall off-hand seeing posts from v1 owners on the VN. Both are designed and marketed as NAS drives. I use the WD20EFRX myself in a duo v1, and it works well.
Thanks for confirming my fears.. a bit of research might have been wise on my part.
I will have to look now at a new NAS..
On the drive comments again I just bought the same model as before as it had performed well but as you say I would have been better with a specific NAS drive, too late now. I will keep that in mind when my 2TB drive needs replaced.
I presume there is no issue having 2 different makes and models of drive as long as the specs are similar?.
Sorry to have to bring the bad news...

Mix and match is fine (and I have done it successfully). Some people think that it is more reliable to mix/match - the theory being that identical drives installed at the same time will likely fail around the same time.
If you are replacing a drive in the array, the number of sectors needs to be at least the same as the drive you are replacing. There have been occasional problems reported here when a replacement drive was short a couple sectors - though I haven't seen that reported in some years.
I suggest googling here on the drive family (or the specific model) - it often is helpful.
Thanks,
I have one more query. I still have a good 2TB drive in my NAS with all my data on it. Will I be able just to switch this over straight into a new NAS and be able to read the data or could there be a problem with the newer os on the new model?.

Unfortunately you can't migrate your disk to a new NAS. The RAID formatting and the OS are not compatible with newer models.
My suggestion is to get a new disk (s) for the new NAS and repurpose your duo to backup critical data on the new one. That's what I've done with mine. Of course you can use the DM in the new NAS if you wish (though exchanging it would be better - https://www.backblaze.com/blog/3tb-hard-drive-failure/ ). BackBlaze has a very different environment from a home NAS, but they aren't the only folks who have had issues with the 3 TB DM.
