HCL-Seagate 3TB ST3000DM001: Is newer p/n:1CH166 included?

I purchased two of these HDDs, i.e. ST3000DM001-1CH166 with Firmware CC43 and installed them in a ReadNAS Duo v2 without any problem. Seagate told me in an email that Firmware CC43 is newer than CC4H.

After moving a lot of TB around on my PRO4 and lots of data verification, I have not run into any trouble with my 4 ST3000DM001-1CH166 drives. Empirically they appear to be "compatible". It would be great if Netgear could confirm this after running their own tests and assuming that they are "really compatible" adding the drives to the HCL

I have 2 of these drives in my duo v2 - running firmware version CC43. Not had any issue with these at all.

Disk 1Seagate ST3000DM001-1CH166 2794 GB (29 °C, Write-cache On). Status: OK
Disk 2Seagate ST3000DM001-1CH166 2794 GB (29 °C, Write-cache On). Status: OK

Both been running for 2049 hours - 86 days

The same problem applies to the 2TB ST2000DM001. The old version has part# 9YN164 and needs firmware revision CC4H, the new version has part# 1CH164 and has firmware revision CC43. This drive is supported in the NV+, but so far I have bricked three brand new drives after just a few days. I would say that the two product lines are different products, and should be separately certified. Can we please have a statement by Netgear on this subject?

How did you "brick" a drive?

I have a Readynas NV+ with four 1.5TB Seagate disks. Two of them were already replaced under warranty. Some weeks ago I wanted to upgrade to the latest Radiator version, but when the Readynas tried to reboot I got a system hang. After some tests Netgear support sent me a new chassis. I put the disks in the new chassis, but still no boot. Then I tried pulling disk by disk to see if the system would start (it should with three disks), and when I pulled disk 2 it did. So disk 2 was preventing the system from booting. These 1.5TB disk are no longer available, and the disk could only be replaced by a 2TB version. New Seagate 2TB disks have 4kB sectors, so I decided to replace all disks by new 2TB versions and do a factory reset. That would initialize the disks for proper 4kB layout. However I first wanted to restore the raid configuration, and I put a new 2TB disk in slot 2. After a few days the SATA interface died, and it did so on all four new disks.....

I will return them to the supplier and get new ones, but this time the proper 9YN164 type for use with firmware CC4H.

When I explained the difference between the two ST2000DM001 versions to Netgear support, and also stated that it was not possible to load the recommended CC4H firmware in my disks, then they told me that the disks were not supported because the recommended firmware can not be loaded.

I think you could challenge that, perhaps Beisser could help. CC4H fixed a particular problem with particular drives, other variants that can't run this firmware shouldn't need that fix, and should be supported.

The point is that the other variant(s) have not been tested and certified. Seagate uses the same commercial names (STn000DM001) for two different lines of products. The two lines can be distinguished by their different part numbers. We don't know the differences between both product lines. IN my opinion only the drives with part numbers starting with 9YN have been certified.

The HCL doesn't say that, it simply lists the drive models with no caveats at all.

The statement on the HCL is: WARNING: Be sure to use only drives recommended in the compatibility list, otherwise, NETGEAR Technical Support can and will deny support.

Your drive is listed, as far as I can see you are entitled to support.

I get your point, but at the same time Netgear recommends to use firmware CC4H with these drives. That is not possible with the 1CH drives, because they are different drives. A have a reply by a Netgear support engineer that in his opinion the 1CH drives are not supported. With that I mean is that the drives may cause problems, because they have not been tested and certified.

You are right, as long as Netgear doesn't recognise the two different product lines and doesn't explicitly tell us which drives they support, you are entitled to their support. However that doesn't help you very much if the 1CH drives just don't function properly. This thread was started in August, Netgear had ample time to react.
