I have two D54250WYK1 NUC computers with MSATA hard drives from different vendors (Crucial and Evergreen.)
One is running a BIOS version from September, 2013. The other is running the latest BIOS from early March of this year.
Both exhibit the same exact issue.
The issue is that the MSATA drives disappear at random times. Mostly this happens during bootup, but sometimes it happens after running for several hours. When they disappear, they are not even listed in the BIOS after a reboot.
A reboot or two brings the drives back, and then we start all over again... either disappearing during boot or after running for some time.
Needless to say, this is extremely frustrating.
I have tried upgrading the BIOS on one of them, to no avail.
I have tried different physical MSATA drives (from both Crucial and Evergreen), to no avail.
I have tried several different operating systems (Ubuntu 12.04, 13.10, and a pre-release of 14.04), to no avail.
I have memory installed that is listed on the intel officially supported list.
I have several of the original NUCs (i3, dual-hdmi) and they have served me faithfully, but this latest Haswell-based batch is leaving me very disappointed.
Please advise on a course of action.
Hello Eric, thank you very much for sharing your issue with us. We have seen this behavior before, and it could be related to the temperature your SSDs are running. Please check the following article, this issue is described here: http://www.intel.com/support/motherboards/desktop/sb/CS-034326.htm.
There is a link on that page where you can submit an email request for a thermal pad to install inside the NUC chassis that will help solve the overheating issue.
