Disk/Video Interface Compatible Floppy Drives
Specs:
- 5.25" half-height
- 180KB
- 48TPI
- Double Density
- Single Side
In general, the simplest way to search for a compatible drive is to search for "360K" drives. Most 1.2M drives won't work. A 360K drive has the right TPI & Density, but merely has two sides instead of just one. The extra side is simply not used by the DVI. It's technically a waste, but there are no half-height 180K drives out there to be found, while 360K drives are still relatively easy to find.

Mounting Holes
There are two common locations for screw holes on the sides of half-height drives. Usually drive mounting brackets will have 4 holes on each side to allow for both types of drives.
The brackets for the upper drive bay in the DVI only have one set of holes, which matches the original drive, and some other drives do not have screw holes in that location.
The lower drive bay uses screw holes on the bottom of the drive, not the sides, so any drive works in the bottom bay.
To use some non-original drives in a DVI, you may have two choices:
- Drill new holes in the upper drive bay brackets.
- Only use the new drive in the lower drive bay instead of the upper bay.
