There's nothing wrong with the products themselves... WDs problem was that they did not make buyers aware of the change they made to the product.

You wont have any issue buying the same brand / model...especially if you want to match your existing (working) drive. If you prefer to do a full replacement of all drives then no probs... just replace them both one at a time(dead one first) giving the system the chance to synch the data to the new drive before replacing the second one. Just make sure that you buy "CMR" drives and not "SMR".

Let me know if you have any questions....I'll try to answer them.

Thanks. Can I just reformat drive 1 (failed drive) to see if that fixes the problem and try to sync it again from D2?

It depends on the mode of failure. If the NAS sees it then you could give it a try using the tools on the NAS. If you are able to reformat, keep in mind that if it's failed once it may not be long until it goes out again.

You should be able to get a new one for $110-$140.

I still have 8 of them. These ones pre-date the removal of SCT-ERC (TLER) so serve nicely in a RAID.
They are getting on in years now though, so they live in the backup box that doesn't get powered up that often (which is why the POH don't reflect the actual age).

The greens were a great drive provided you disable head parking and kept them spinning 24/7. Perfect for NAS use until WD decided to call them RED and make the greens cheaper.

Code:

/dev/sdc -    WDC WD20EARS-00MVWB0    - 2 years 152 days 20 hours 20 C
/dev/sdk -    WDC WD20EARS-60MVWB0    - 5 years 1 days 21 hours 20 C
/dev/sdl -    WDC WD20EARS-60MVWB0    - 6 years 281 days 21 hours 21 C
/dev/sdm -    WDC WD20EARS-60MVWB0    - 6 years 281 days 21 hours 20 C
/dev/sde -    WDC WD20EARS-60MVWB0    - 6 years 281 days 22 hours 20 C
/dev/sdh -    WDC WD20EARS-60MVWB0    - 6 years 281 days 22 hours 20 C
/dev/sdi -    WDC WD20EARS-60MVWB0    - 6 years 282 days 1 hours 20 C
/dev/sdj -    WDC WD20EARS-60MVWB0    - 6 years 283 days 5 hours 21 C

I've a stack of Reds in service, but I've started to use Purples. Cheaper, and order of magnitude better NRE rate and come with all power saving disabled out of the box. What's not to like?
