Hi Louthrax...if you dont have any floppy port on the MB but any IDE free, you can get an LS-120 or LS-240 drive unit on Ebay or similar. These are high speed / high capacity floppy drives, that can use standard floppies as the extended one, the LS [Laser Servo] discs. It´s what i did some time ago to get floppy support on some pc´s at the office. Windows XP works with them without problems. I don´t know if they works so well under Windows 7, but being IDE devices, they should work.

Thanks for the info. Not completely sure if I have IDE ports, but that looks like the best and mode solid solution !

All in all, I'd still format the disks on an MSX, since there's been some trouble with PC-formatted 720k disks at least on my computers.

Yeah me too. But the drives which cannot format 720K floppies doesn't read those formatted on MSX as well (read errors on reading sector 0, period).

@luppie: my 'chinese' is labeled as Grand-X USB floppy adaptor. But has the Mitsumi floppy inside, btw.

I'll think it's save to say that Windows 7/8 (x86 & x64) do support 720kb disks, but it depends on what drive you are using.

When I was adapting drives for Panasonic MSX machines, I discovered that the most recent diskdrives don't have a Densitity Select switch any more. Probably the drives that are lacking a densitity switch don't support 720kb disks.

For the record: the external USB drive Sony MPF88E does work perfectly with Windows 7 Professional and reading/writing 720kB disks including formatting them in DOS windows (FORMAT A: /F:720 works fine and also FORMAT A: /T:80 /N:9)

Single sided disks (360kB) don't work, but I never used them on MSX.
Fun part of the Sony MPF88E: it's a double speed diskdrive, so it read/writes faster!
You need a tool for writing the MSX bootsector though... (MSXDOS1/MSXDOS2)
I once saw a Japanese tool for PC which could do this (formatting including writing MSX bootsector).

2 ways to get the boot sector on it:
1) format the disk on an MSX
2) create an MSX disk image somehow, format it on an MSX emulator and write the disk image (or only sector 0) to the floppy disk...

very good suggestion this Sony drive! I'm going to buy it.
But before I'd like to know: is it possible to *dump safely* MSX floppies to DSKs?
I have much material to preserve, even rare...

It's only possible if there's no copy protection. If there's a copy protection you can only use DMK with READ-DMK on real MSX.

Or easier: use MSXForm which can format disks on PC under Windows 7 and put MSX-DOS1 or MSX-DOS2 bootsector on it. Wink With the Sony MPF88E formatting is twice as fast Cool
Or adding MSX bootsector manually on real MSX with MSXBoot if you formatted disk on PC.

Regarding 1): there is also a fast format for MSX which writes only a fresh boot sector, FAT and directory structure.
You can convert an MSX-DOS1 bootsector to an MSX-DOS2 one with FIXBOOT.COM, if I'm not mistaken.
