My i5 is continually losing the WD Red 1TB spinning disk, although the system boots and runs fine off the Crucial M550 256GB mSATA SSD under centos-7.1
Question I have, given other folks complaining about their NUCs similarly having problems with the spinning disk, is:
- is the disk bad
- is the nuc bad
- is the bios bad
- how can I tell ?
The system is rock solid running off the SSD, it's just the spinning disk having problems. I had some periodic issues running ESXi in the past where the laptop disk would throw errors and my datastores would disappear (this was before I added the mSATA SSD) where a complete power removal, plug it back in, and power it up seemed to do magic.
Some error messages from syslog are online here if you want to take a look. At this point, even powering the system down, removing power from the NUC for a while, and plugging it back in and restarting does not work. The disk gets tossed at centos bootup.
- Bios is DMI: /D54250WYK, BIOS WYLPT10H.86A.0035.2015.0126.1814 01/26/2015
- os is centos-7.1
- kernel is centos-7.1 Linux version 3.10.0-229.1.2.el7.x86_64
