Hi all,

Have you been doing any disk imaging where you need a drive component (in our case, we are using a Greaseweazle) that requires external power to capture? 

We have a Greaseweazle connected to a 5.25 floppy drive that is unable to capture disk images because of, what we think is, a power supply issue. Guidance for the Greaseweazle and other disk imaging groups have told us that we may need an external power supply, specifically:  "For a suitable drive power supply for 3.5- and 5.25-inch drives, search for "Molex power supply". These usually feature 5V and 12V supply at 2A, and a full-size Molex power connector; They connect directly to a 5.25" drive, or to a 3.5" drive via a Molex-to-floppy adapter cable" (Source)

We have considered 
But we have seen some reviews where the power levels are inconsistent. Has anyone tried the Coolerguys adapter? Or have recommendations for a better product that has worked for you?

Thanks in advance for any help!

Hi Meghan,

We've been using that Coolerguys power adapter (without the on/off switch) with our 3.5" floppy drives and Kryoflux for a couple of years now.
