Using Scsi attached storage (uaspstor.sys) is causing BSOD & system hangs.

Hello

Try this one:

" Microsoft added native support for UAS to Windows 8. Drives supporting UAS load Uaspstor.sys instead of the older Usbstor.sys. Windows 8 (10) supports UAS by default over USB 2.0 as well.
That explains why UASP device works in "UASP" mode even if I plug it in on a USB 2.0 port.
Replace uaspstor.sys with usbstor.sys?

• boot into safe mode: within Windows, hold the SHIFT key and click Restart
• click on the Troubleshoot button
• select  Advanced Options
• choose Command Prompt
• login into your admin account
• from command prompt, type C: and press Enter
• type cd windows\system32\drivers and press Enter
• type ren uaspstor.sys uaspstor.sys.old and press Enter to rename the file uaspstor.sys into uaspstor.sys.old (or whatever you like)
• type copy usbstor.sys uaspstor.sys and press Enter to have an additional copy of usbstor.sys renamed into uaspstor.sys
• close your command prompt by clicking on the "X" in the upper right corner
• click on the Continue button to exit and reboot into Windows 10 "

For me it works. Finally.

Unfortunatly my old workstation experienced a critical failure unrelated to the usb drive problem requiring me to buy a new pc. I am now the proud owner of an Alienware Area 51 system.

Problem solved.

Hopefully this workaround turns out to be usefull for other people experiencing this type of problem

I would, again, uninstall the drivers, then re-install them in Troubleshoot mode. (Right click on driver file for the troubleshoot option. Use the Troubleshooter to install the driver(s), not just to check the hardware.)  I am pretty sure the problems that both you and WallyGator describe are due to motherboard (USB port) drivers. I have found the Troubleshoot-installation tool to work quite well with issues concerning wayward legacy drivers and programs.

Actually, I did not find out how to install driver in Troubleshoot mode. Uninstalling and re-installing in "normal" way gives no success. But, anyway, what I found in fact, the external portable disk works properly on USB 2 ( Win 8 / 10 ) only with usbstor.sys  driver type, and as OS addresses to uaspstor.sys , the system has to be deceived by replacing the last one with usbstor.sys and renaming it to uaspstor.sys.
