Hi,

 

I've just installed a new Samsung evo 500gb SSD as a passthrough to my Windows VM. It works, but during prolonged use, it fails. The VM suddenly becomes unable to access the drive, and I need to reboot Unraid up to 3 times to make the device responsive again. I doubt it's a hardware problem because the disk is new. Also, previously, I was using an OCZ 120gb SSD, which was set up differently (part of the array, but independent of the spinning disks) and experienced similar errors (though, in that case, it locked up the entire machine).

 

When no SSDs are present in the system, everything works perfectly. All observations point to there being a problem specifically with SSDs, and I'd really like some help fixing it. Today's syslog is attached. Can someone give me some insight? The device is sdc.

Happened again. Here's a syslog with a ton of errors. Someone, please help me get past this. syslog.txt

It's a hardware problem, try replacing the SATA cable:

Thanks Johnnie.black. It ended up being the sata power cable for the drive. I know it's a very late response, but just wanted to say thanks for the help!
