I am running portable EAC from an external hard drive and have an external CD/DVD ROM drive for ripping. It works fine from one of my laptops running Windows 10, but it doesn't work on my other Windows 10 laptop and I can't figure out why. The CD/DVD ROM is recognized by the PC, but not by EAC. I tried installing the wnaspi32.dll file and changed the SCSI Interface settings in EAC, but it just shows a blank list of drives. I compared the drivers for the CD/DVD ROM between the two laptops and everything is identical from what I can see. The laptops are also nearly identical - a Lenovo X240 and a Lenovo X270. Does anyone have any ideas on what else I should check? Thanks.
Have you tried running EAC as an administrator?
