When using IBM's SaveDskF program (SAVEDSKF.EXE) to save an image of a diskette, one of the options is /D "omits the 1 sector leader and inhibits data compression." What is the "1 sector leader"? The documentation also states this as omitting the "file header."
The relevant options for the SaveDskF program are
/N inhibits data compression
/D omits the 1 sector leader and inhibits data compression
/A saves all sectors of the disk
If /N is used with /A the resulting image file size is 1,474,601 bytes, but if /D is used with /A the resulting image file size is 1,474,560 bytes. So what is this 41-byte difference?
