not seeing all optical drives

[fpefpe]

Hello --- in addition to the internal drive on my laptop I also have others connected via usb3 ports. The windows "dev manager" "sees" all the drives, but when I start up makemkv one of the drives is not in the list of "sources" -- is there a way to debug this an find out why all the optional drives in the "source" list? Thanks

Hello -- as it turns out the drive not seen by Makemkv is

SlimtypeDVD A DS8A1H

This (slim) portable drive that connect to the computer via usb3 port

The question is, does Windows consider it an optical disk? Or does Windows consider it a "removable drive" and is blocking access to it because of the "ransomware protection" introduced in 2019?

umm ... not aware of that distinction --- how can I find out how its connected?

its listed as a usb cd/rom device now

this is very weird --- I connected the (external) drive to another computer, and on that one too makemkv did not see the drive

If Windows thinks it is only a CD drive, then it doesn't surprise me that MakeMKV doesn't list it as source.

thanks for the reply ---

Not sure how windows see the drive, but the device manager lists it as a dvd drive --

I put in a data dvd and was able to see and copy files from it to the local drive

Thanks for the hp/forum link but it did not seem to point to a solution

Thi is totaly confusing ---- It seems that makemkv (so far) is the only application that can't "see" this external dvd

Slimtype DVD A DS8A1H WH66

Is there a way to debug why this is the case?

This is the msinfo32 info --- is there any other place to check? Thanks
