I have a XPS 8900 that hangs at startup when I have my external HDD (Toshiba Canvio USB 3.0) plugged in. When I unplug the external HDD, this allows the PC to boot to the sign in screen. The next time I boot the pc it may startup normally, but the external HDD doesn't show up in "This PC", etc.
I use this external drive with Acronis True Image 16 to make daily backups (twice a day-at set times) so if it is not recognized after startup, the backup will not activate unless I unplug and plug it back it. Any ideas?
UEFI (BIOS)?
