Hello. I am new here, and want to ask a question in regards of the excellent diskmanager software of Rudolf Lechleintner. 

Simply i try writing .dsk file to floppy by drag and drop, but it only is showing following message: "Disk full! - Image too small"

Since i using regular 720kb floppy setting i do not understand this. The .dsk file also is 720kb, so i think this should work? When i trying 1,44mb , it works to drag and drop, but this is not compatible setup for MSX? 

Please help me. Thank you so much! Smile

Looks like you are trying to put a disk image into a disk image.

I've just started using Disk Manager as well to try and write dsk images to disk and I noticed this as well, but the correct way to load the files that are ready for writing is to use the "Open" from the top Gui menu and select the disk image you wish to write from. This should load the files, although for some it may have difficulties seeing what is on the disk.

However, I've been unsuccessful so far with actually getting a dsk image to write at all correctly to a formatted disk that was formatted using Disk Manager. I select 2 sided, 720k as my format option and for boot sector... Not sure what to select here or if it needs to match a specific title, but there is a MSX-Dos 1 option, MSX-Dos 2.2 option and Dos. 6.0 I believe it was?

Just curious, but what are the most common setups or programs that people use nowadays for both formatting disks and writing disks and the settings you use in these programs? I'd love to know since I've already gone through several floppies, some HD with the hole covered with black tape and some that are actually DD diskettes and none have seemed to work. Seems that especially formatting the disk with my MSX Turbo GT will create a formatted disk... that my PC can't read at all...

If you format on a TurboR, there are 2 options :

- you boot while pressing "1" key : DOS2 will be de-activated and the disk will be DOS1 formatted
- you boot without pressing "1" key : DOS2 will be not de-activated and the disk will be DOS2 formatted

Most DSK files on the Net are DOS1 formatted. So if you try to write them on a DOS2 formatted disk, it can't work.

DOS2 formatting can however be required for some games, especially MSXturboR games running in R800 mode. Unfortunaly, the DSK files on the net for these games are generally wrong (DOS1 formatted). So, you need first to extract all the files and build a correct DOS2 formatted DSK.

Concerning the DSK without visible files (because all is sector-based), they have a special format. Writing on real disk is not always successfull.

Sorry for the wrong presentation of my text, but the features of this forum don't work correctly this week-end Sad

Great, thank very much for your help mars2000you! I will try this out soon and see if I can get this to work. That all makes perfect sense. A friend of mine had mentioned this to me, but I don't think I really understood the different formatting options well enough at the time.

I also experienced that if I wanted to put a physical disk into a disk image, the image size was too small (the other way around)... Dos1 into dos1 that is...

Formatting in DOS1 or in DOS2 doesn't matter if you overwrite the disk with a complete disk image. The difference between DOS1 and DOS2 formatting is overwritten by the disk image itself.

So, DOS1 formatted disk images can be put on a DOS2 formatted disk withotu problems. Afterwards, the disk is DOS1 formatted, of course. The same for the other way around. For plain DOS disks, you can convert DOS1 to DOS2 with FIXDISK.COM. Don't do that on games with special boot sectors to load them though.
