Writing the disk image works fine to get that onto a diskette. It sounds like you are trying to copy the actual disk image to the floppy disk itself which simply won't fit.ĭOS 6.22 from my recollection doesn't use 1.44MB Diskettes it uses DMF Formatted diskettes which hold 1720K. You need to use an Imaging program such as WinImage to write the diskette images. img file meaning it's impossible to fit onto. I'm super pissed at this because just about every version of DOS 6.22 is 1.44mb per. Purpose of this program is making image files of floppies - for usage with emulators on PC, data preservation.Then, file transfers & writing image files. If you format a diskette there is usually a bit of extra space used, particularly if formatting on Windows. 80 18512*2=1,474,560 bytes, /1024=1440K.įormatting adds a boot sector of 512 bytes, 18 sectors for the FAT and the mirror FAT, and 14 sectors for the root directory. Somehow that got shortened to 1.44MB, even though that's a decimal being applied to a binary.Īnyway, unformatted capacity is derived from 80 Tracks, 18 sectors per track, 512 bytes per sector, and 2 sides. The correct capacity is 1440K (as in KiB). The "1.44MB" floppy diskette's are mistermed. Even new floppy disks sometimes have bad sectors. Does it show bad sectors? A disk with bad sectors cannot take an image file. If you get an error halfway through writing the disk image with rawrite, then format the disk you are trying to write to and the run CHKDSK on it. Use rawrite or rawrite32 to write the image to the disk. HOWEVER when you write the image to the disk, >with the correct disk image writing software<<, it will overwrite the old format and use the full 1.44mb If you format a disk then some of that disk space will be used for the format layout. Much like putting furniture in a room means you can't use all of the carpet. Formatting the disk puts some system data on it, reducing the capacity. The only things that can make it read smaller than that are putting data on the disk, or there being bad sectors on the disk. You cannot change the size of a disk between 1.38mb and 1.44mb. I understand the frustration, though, so I'm willing to let it go this time. First: Calm down - We are not responsible for your predicament.
