Since update KB3081448 my Seagate Expansion 1Tb USB 3 portable drive formatted NTFS is not shown in File Manager. I noticed when using "Safely Remove Hardware ...." it shows the disk as SCSI (UAS). I was using this successfully for File History. It still performs perfectly on my Windows 7 desktop and disk check shows no errors. Usb pen drives are identified correctly. My system is a Lenovo E520 Edge 64bit Windows 10 Professional. Is there a fix for this?
Since posting this I have tried another portable drive - a WD Elements 2Tb USB drive also formatted NTFS which also fails to appear in File Manager but works perfectly on my Windows 7 Desktop PC
