I've had problems with SEVERAL of this same model.
Using 4 different types of drives.
Customer will bring it into the shop and it works fine. The last one I ran memtest for 14 hours, and upon reboot, no sata.
Take the drive and plug it into a different machine and it's fine.
The sata just goes away, Glad to see I'm not the only one with this issue.
Oh finally! Thank you! I really hope someone can help us to find a solution!
Just now, I got a call from the Intel customer support.
They told me they know the problem on this model. There's a little SATA component to replace and they will send me these parts in the next days.
I suggest you to open a ticket.
Hope you will solve it.
Beware!! I has this exact same issue, I was sent a replacement board and all worked fine for a while but gradually the issue has come back. I thought it was a problem confined to SSDs so I replaced with an mSata and HD but it makes no difference, the mSata boots but my data drive keeps disappearing. All firmware and drivers are latest.
This is a very disappointing bit of kit, I've wasted so much time trying different drive types and combinations. Now I must go through support again and try and get another board or new box altogether - I doubt I'm in warranty anymore either.
We have seen that situation with some NUCs and that is related to the SATA daughter card that is attached to the NUC so as a troubleshooting step you can request the SATA daughter card as a replacement or you can also get your NUC replaced. If you want to replace your NUC you must keep any other component like the SSD, wireless card, power adapter and cable, etc. Please contact your local support center using the following link: Contact Support
If you replace the SATA daughter card only, please click here Intel® NUC SATA Card Replacement Guide
UPDATE: I received a replacement SATA board, again the same problem, so i have now received a replacement NUC unit and all seems ok so far, no disappearing drives. I just lost my musical Intel box in the swap out process! oh, and all my licenses had to be replaced due to the hardware change :-(
It is not necessary to buy new licenses. In the case of Windows® operating system you just need to reinstall it and use the product key number; if it doesn’t work, contact Microsoft, give the proof of purchase of the license and they will give you a new product key number.
Not quite so simple for me, all my licenses were through the now retired Microsoft Action Pack Subs, its not a big problem, instead of Office 2010 i've installed Office 2013 as i still had some of those licenses. It's the other small vendor licenses that i've got to sort out, you know the stuff you buy of the internet and the email receipt gets filed away somewhere.
