Disk On Module not showing up

I have 9x 128MB Disk On Module SSD's that I've just gotten from Ebay and have just discovered they contain a proprietary DOS based software on them.

I need to format these drives so that I can install my DOS based software on them. Using F5 to interrupt DOS isn't working for some reason.

I have an external hard drive unit with IDE pins that I usually use for this purpose, but it's not showing up in Windows Explorer. I can see it in Device Manager, and it's showing no issues. Windows is making the sound acknowledging that something has been plugged in, but I can't see the drive. As I don't know what the drive has been labeled, I can't get to it in DOS (Note: Searching through the alphabet in DOS, I'm not seeing any drives that I'm not already aware of.

I've placed the drive in a P3 computer we keep around the shop in IDE 2 in slave mode. When you look at the device properties from device manager, it shows the partition style as Master Boot Record.

Anyone got any ideas on how to get this drive to show up so I can format it?

It also doesn't show up in the Disk Management window.

Correction, I can see it in Disk Management. However the only options there are to delete the volume. No format, no nothing. The drive shows up as a 2mb and 122mb set of partitions.

And just like that... nevermind! Deleting the drives gave me the ability to reformat like I wanted.
