Summary MESS-specific 07936: any system that uses floppy disks: If you create a disk with certain formats and unload it, it becomes unusable
Description If you use the File Manager to create a new floppy, then choose [empty slot], then attempt to load it again, you get an error.
The newly-created disk is unusable. You have to throw it away.
Steps To Reproduce You can try with any disk-equipped system, but x820 will do as an example.

>mame x820

Press Scroll-lock, then Tab, and select the File Manager.
Choose an empty floppydisk slot, press Enter. Choose [create]. Type in a filename (it requires an extension too).
Choose Create. You get a list of formats, choose hfe or imd, press Enter.

Now you're back at the File Manager and you can see that the disk is now loaded.
Hit Enter again and choose [empty slot]. The slot is now empty.
Hit Enter once again, find the new disk and load it. You'll get an error.

The error might be "Unable to identify the image format", or just "Error:".
The new disk is therefore useless.
Additional Information EDIT: Testing shows that mfi and mfm do work, but hfe and imd do not. More testing will be needed on other formats.
