DS214 HDD upgrade. New disk 2 crashes

[Jagmanstu]

I am trying to upgrade my DS214 from 2 x 2Tb to 2x 4Tb drives. The first new drive installed and is working fine but the second drive just crashed and became unusable. In case the drive was faulty I returned it for another new one and the same thing happened. While waiting for the new drive I did install one of my old drives in slot 2 and that worked fine. However, since installing the 2nd new drive, which crashed, installing either of the old drives just crashes them.

The NAS is working with Drive 1 OK and drive 2 crashed and I can access data. Can anyone explain what I need to do to resolve this?

Thank You

I'd take the new (crashed) drive to a different computer system and run MFG's Drive Software tests on it, Full test, not quick one, Verifying once and for all if drive is good, or not...
That's the only way you will know for certain what the status of the drive is...
Another (one of many) reason to return Drive's SMART access to Synology.

Note that if you run DS FINDER on your phone, you can still get to some of SMART Data.... on NAS, even though Synology removed it from NAS access... (Which means it's still There.... Just not accessible !!!!

Jan,
Thank you for your reply and apologies for my delay in replying to you. I now have an external case for the HDD for use with my computer, but I'm not sure which software to use. Both my original drives are WD Red and labelled as NAS Hard Drives. They always worked perfectly over the several years I've had the NAS.
Incidentally the new 4tb drive that is working OK is a Seagate Iron Wolf drive, but having now discovered that Synology has a list of approved drives I find that this one is not on the list. I sent back the second 4Tb drive, so if I buy a new one is it OK to mix drives and if so what are the best ones to buy?

If WD Drives, use WD Software, If Seagate, Seagate.... Etc,,,
Search for "XXXX Disc Diagnostic Software", where XXXX is Drive MFG Name

If MFG's software says it's good, it's good!! If Bad, then you know that!

You will get varied opinions on "best models to buy" - my preference are the WD (Western Digital) Ultrastars. They are an enterprise class drive with very good quality and reliability.
