December 28, 20196 yr Bought a new Samsung SSD 860 EVO 500GB drive to use for the cache and as soon as I push the drive into the server, I lose all communication with the server. Only option following this is a hard shutdown to get it back. The drive has to be removed for Unraid to operate properly. I thought it may be a bad drive so used an external reader with my WIn 10 laptop and reads just fine. No SMART errors with the drive. Mounts and is available almost instantly. Any ideas? Never had this happen before but is my first attempt at installing an SSD drive into the server. Thank you for any help.
December 28, 20196 yr Community Expert Are you hot-plugging this SSD? If so, shutdown the server down. Plug in the drive. Now, connect a monitor to the server and start the server up. Observe what is happening on the monitor. Report back.
December 28, 20196 yr Author Yes I was but tried it as you suggested. Kept receiving an error that would not clear during boot sequence and would finally stop. I took some pictures of the screen to try and help. Attached are the pictures of the error and then where the boot sequence stopped. Shut down the server, removed the drive and restarted without any difficulties. Definitely does not like the drive. Thanks again for your help. I really appreciate it.
December 28, 20196 yr Community Expert Did you see the Unraid boot menu? Are you connecting the SSD via a USB connection?

Yes the errors started after. 5 minutes ago, Frank1940 said: Are you connecting the SSD via a USB connection? No, I found that error to be weird. The drive is plugged into a 2.5" to 5.25" adapter then secured to the carrier tray, then plugged into the backplane. This is the adapter I am using.

December 29, 20196 yr Community Expert You should always post the complete diags so we can see the hardware, based on that board are you perchance using Supermicro SAT2-MV8 controllers? If so they have known issues with some recent devices, you'd need to connect the SSD to another controller, like the onboard ports.

I have been using Unraid for several years but have only recently started to try and make the performance of my server better so am new to the forum format. Appreciate your help though. server-diagnostics-20191230-1114.zip
