I recently got a DXP2800. First I bought WD Plus drive that was originally listed as compatible. Apparently it got removed but not before I bought them. I got the write error “Write FPDMA Queue” and that’s when I found out they were no longer listed as compatible. So then I bought two 8TB WD Pro drives also listed as compatible. I got the write error again!!! I’ve talked with support and don’t have an answer yet. I bought the WD pro because it was all I could get in a short amount of time. I decided that perhaps my DXP2800 was defective so I returned it and got another. I installed the WD Pro drives and immediately got the write error. This is kinda ridiculous. How many hard drives do I have to buy to find ones that work? I also ordered Seagate drives but won’t get them till Wednesday. Anyone else struggling to get drives that work? The write error is considered serious but I wouldn’t have known it happened if I hadn’t checked the log files. here are the drive models I’ve bought:
WD - Red Plus 8TB NAS Internal Hard Drive
Model: WD80EFPX
Western Digital 8TB WD Red Pro NAS SATA HDD, 3.5" Internal Hard Drive HDD, 7200 RPM, 256MB Cache, CMR - WD8005FFBX
Edit: Playing around today I’ve noticed that if I shut down the NAS, then start it up and begin a file transfer I immediately get a write error. After that it runs fine. If I do anther big file transfer I get no errors. But if I shut down and restart I’ll get an error on the first file transfer.
Those drives are compatible, that shouldn’t be an issue, but the error has to do with native command queueing (NCQ). No idea why that would pop up, but I’d suggest talking to Ugreen’s support about this, as no-one here can help you fix the issue.
I have been talking with their support but thought I would come on here and see anyone on here has run into this with WD drives as well. I did talk with a guy on Reddit who had the same problem. He switched to Toshiba drives and it went away. Unfortunately I can’t find any compatible Toshiba drives in my size range.
I have used four 4 TB WD40EFPX drives without any issues with the DXP4800 Plus, so as I said, those drives should be compatible, as the only difference is the size of the drives. Obviously different NAS model, but we’re talking standard SATA hardware here, so something odd is going on.
After my dxp2800 finished formatting the drives I tested by uploading about 200 GB of movies. I instantly got the write error. After that everything uploaded fine and no more errors. I am working with their support as well.

I was concerned that I might be trying to copy a file too soon after a reboot so I made sure to wait 10+ minutes after booting to transfer a file. It didn’t change the result, still got the write error. I’m waiting to hear from support on this new info.
UGREEN had me change the SATA data link speed from 6 gbps to 3 gbps to test the stability of slot 2 (which is the only slot giving write errors). It worked. This is not the fix but just a test for their engineers.
There really shouldn’t be these kind of SATA related issues this day in age. SATA 3.0 turns 17 this year, with SATA being 23 years old. All the bugs should’ve been worked out by now, which makes this a real headscratcher.
