Acer aspire xc-705, upgraded from windows 8.1. to windows 10, and switched disk to SSD, having a lot of errors eventid 154. 
 
There is no problem running windows 8.1,  ssd have been used for 1 year in another PC.
 
Then i tried once more, I cloned the original disk, and restored to factory settings, upgraded to windows 10, and hereafter I reduced the size of partions, so I could clone the disk to the ssd disc.
 
Still disc errors, when I put the ssd disc in a external usb 3.0 disc bay, no errors, I use HD Tune pro for testing, when I put the disc back in the Acer, it gives errors, tried a smaller ssd disc, same problem, tried new cables, another sata port, same problem.
 
There is no errors with the build in disc  (western digital ), the ssd disc is a Intel SSD 520 series 180 GB.
 
Any idears, I am completly lost now.
