I would like to let you know that I have bought a Western Digital 2TB WD20EURS hard drive and it works with my NMH305!!
The listed compatible 2TB WD W20EVDS is not available and also more expensive than the WD20EURS!!

Thanks for the update. Yeah, Cisco haven't updated the list of compatible HDs though but as per Tech support conversations a couple of years ago, other brand and models that are not listed on their list "may or may not work". So thanks for update and hopefully, if I need to replace my HDs, i'll have the WD20EURS as an option.

Hello, I bought a NMH300, and I need 1 or 2 hard drives. W20EVDS model as discussed in the list of compatible hardware from Cisco, and WD20EURS is not. I've been looking and are practically identical, both are at 3 Gbit / s, but the finished model is 32 mg DS cache and finishing RS models has 64 mg. Both are 7200 rpm, low power and low noise.
I have found the model for 133 € WD20EARS, and I think I'll buy it.
As I read, one of the inconsistencies is that hard drives are supported 6Gbit / s.
I saw a model WC30EURS, SATA 3Gbit / s at 7200 rpm and 64 mg of cache, and I have fear in buying it and not work.
I do not understand because a new firmware update, to serve us 3TB hard drives.

The 3TB disk will work, but you will only be able to use 2TB. I replied to your other post saying to use the steps here:
The reason why 3TB disks won't see more than 2TB is because the NMH does not support GPT disks, only MBR. MBR can only handle 2TB partitions.

If you just dropped them in, you will eventually have problems if you did not format the drives properly as outlined in the link I posted.
I bought the same disks and just dropped them in. Eventually, my NAS would start dropping off the network and showing device unavailable.

I´ve bought only one WD20EARS.

Why the new disk format that makes the NMH300 is not valid to work properly?
Since I have a hard drive like yours, WD20EARS, what is the exact command sequence you put fdisk?. You explained it but I do not understand.
You indicate that this is for discs 4kb sector size. How do you know that this album is 4 kb?
If this works, I just buy another hard drive.

The third post in my thread has all the fdisk commands. The NMH formats using 512kb block sizes, but the wd20ears uses 4k block sizes. When improperly formatted, the partitions are not aligned with the blocks correctly and can slow performance three times slower. Since the OS of the NMH runs off disk 1, I believe that when copying files, performance is so poor the OS becomes unresponsive.
