I bought 3 ReadyNAS (over the course of 5 months), and populated them all with identical Seagate Barracuda'sThey are the Barracuda LP ST32000542AS model, on the HCL and I chose these because there were no special firmware requirementsOver the past month, one of my NAS is starting to send regular SMART email alerts, about disk problemsInitially it was disk 1, but the past week Disk 4 is also starting to get errorsHas anyone had a similar experience with these drives? Could it be something to do with the NAS chassis? My other 2 NAS (including the oldest one) use the same drives without problems Im starting to think I made a rookie error by buying homogeous drives.

Under Status > Health > SMART+ what are the firmware versions on the different disks?Disks can and do fail at any time, so it certainly is possible to have problems with a few disks in one NAS but not in others.

On all the Barracudas (all 3 NAS), the firmware is CC34Maybe Ive just been unlucky, it just struck me as worrying that both failed drives are in the same NAS

What SMART errors exactly are they getting and what's the count like?You can power down the NAS, remove the disks (label order), connect them to an internal SATA port in your PC and run a long/extended (can't remember what it's called) SeaTools test on the drives.Another option would be to run the "Disk Test" boot option: http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu

Keep an eye on the drives and keep track of the errors. I have an ST31000528AS that started throwing errors and increased up to 7 back in Feb and then stopped. The drive is still in service and has logged almost 4,000 more hours without another error being reported. I have another that started increasing rapidly in large increments and when the errors reached 334, I replaced the drive in January. I am debating on returning it for an RMA rather than just discarding it. (My array started with 4x1TB Seagates in two NVX units plus two spares. I am currently running 2x3TB Hitachi + 2x1TB Seagate in each unit and plan on going on to 4x3TB in both units, so the 1TB drives would be surplus.)

My desktop is a mac, and my server machines are all linux. I do have a Windows laptop somewhere, but obviously no SATA on those.Another option would be to run the "Disk Test" boot option: http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menuI'll try this todayThanks

You can use 3 TB drives with your 2 TB drives if you are using XRAID2 and have firmware of 4.2.16 or later.

Thats great, Thanks Stephen

Be sure to back up all your data before you start and replace the drives one at a time. After you have replaced the second drive, it will take at least one and maybe several reboots before the vertical expansion starts and it will take much longer than the resync.

I when through this when I replace two 1TB drives with two 3TB drives on both of my NVXs.

The failing NAS is actually just a backup NAS for my 1st one. I rsync it across each night

I havent done a volume expansion before, so thanks for the tip!

Sounds like my set up. Two NVX units, one is the primary and mapped in Windows, the other is the nightly rsync back up target of the first.

In that case I would go ahead and update the drives in the backup. When I do any updates, I do it on the backup (NVX Pioneer) before I do it on the primary (NVX BE) a week later.
