" Cylinder:
When disks are placed directly above one another along the shaft, the circular vertical "slice"
consisting of all the tracks located in a particular position is called a cylinder. You can set the number
of cylinders for a HDD. The minimum number you can enter is 0, the maximum number you can
enter is 65536.

off. The minimum number you can enter is 0, the maximum number you can enter is 65536.
" Sector:
The minimum segment of track length that can be assigned to stored data. Sectors usually are grouped

Mode floppy disk drives (FDD) are 3 1/2" drives used in Japanese computer systems. If you need to
access data stored in this kind of floppy, you must select this mode, and of course you must have a 3
Mode floppy drive.
Warning
Setting a value of 65536 means no hard disk exists.
