Verbatim 43888 BU40N randomly stopping

[Mattt]

I just got a Verbatim 43888 from Amazon EU today, it has the BU40N internals which I flashed using the guide+GUI tool to 1.03, I’m ripping my second disk now but I keep having to baby sit the device as it seemingly randomly stops reading and spins down/stops.. MKV just sits and waits, bizarrely I found that opening my web browser wakes the device up and it carries on reading from where it left off.
I have tried disabling all power saving in windows but that has not made any difference.
Any ideas on what could be causing this would be much appreciated as I’d like to be able to do other things and not baby sit the drive/MakeMKV continuously.
many thanks!!

The enclosure electronics is very power hungry. Best connect ot USB-C or a powered USB hub.

Make sure "disabling all power saving in windows" includes the USB selective suspend setting:

Edit Power Plan -> Change advanced power settings -> USB settings -> USB selective suspend setting

Third possible solution: Buy an USB-Y-Power-Cable with USB-C-to-2x-USB-A.

I've adviced this also in the past but in relation to the specific disc it couldn't be enough. With 2-layer 4k disc the disabled power settings could be sufficient but not with 3-layer discs. Usually these need more power.

The issue is resolved!

Thank you all for your thoughts and advice!

They helped me focus on what I suspected the issue was (power related, software or hardware)

I had already got all the ‘hidden’ usb power settings but had forgotten Asus Armoury Crate.
Also, I found, of the 3 usb-c outlets on my motherboard only one of the rear ones seems to be full bandwidth/60w, of course I’d picked the wrong one.

I’m using a 3m usb-c to usb-c 60w cable and am blazing my way through my 4k collection now.

Many thanks to you all!

interesting observation. i too am using Asus Desktop PC, with "Armoury Crate" installed.
is there any settings in the Armoury Crate" that you changed?
would be great if you could share more on what settings was changed for all to be aware off.
thanks in advance.

Welp, I feel a little dumb, it would appear I’d not updated the app in a very long time, there used to be a ‘Power Saving’ panel which is not there any more since I updated the other day.
There are some references I found via google suggesting the app could be problematic.
Let’s leave the advice as
‘if you have this issue, ensure all apps and drivers are up to date and you power cycle your pc and disk drive before seeking further help’
