F2H (FLOPPY TO HARD DISK) is a utility to copy a diskette to
hard disk or RAM disk at very high speed.
See the following table for benchmark results.
----------------------------------------------------------------
| H2F vs XCOPY F2H vs XCOPY |
| -------------------------------------------------- |
| Case 1 (1.2MB) 8 vs 40 8 vs 17 |
| Case 1 (1.44MB) 9 vs 50 9 vs 19 |
| Case 2 (1.2MB) 9 vs 33 9 vs 18 |
| Case 2 (1.44MB) 8 vs 40 9 vs 19 |
| |
| Note: (1) Case 1 contains 36 files and no sub directory. |
| Case 2 contains 13 files in 21 sub directories. |
| Total file size in both cases is about 300 KB. |
| |
| (2) Performance varies on different system. The |
| above benchmark result is provided as examples, |
| NOT guarantee. |
| |
| (3) The above results were measured with a RAM disk |
| on a 33 MHz 386 compatible system. |

H2F (HARD DISK TO FLOPPY) is a utility to copy recursively from
current directory on hard disk or RAM disk to a diskette at very
high speed. This program combined with F2H is ideal for backing
up a small directory.
See the table above for benchmark results.

FMT is a utility to format 360KB, 1.2MB, 720KB and 1.44MB
diskettes. Features include no keyboard operation, serial number
assignment, label assignment and bad sectors handling.
You type the program name at DOS prompt to start and press the
ESC key to end, no keystroke in between!
The serial number and label can be assigned incrementally with
a text file which stores the serial number and label for the
next diskette to be formatted. You can keep more than one text
file for this purpose. Before exit, FMT will update the file
automatically.
Conventionally, a cluster is marked as bad cluster if the
formatting program fails to access after three tries. FMT,
however, adopts a more strict policy to ensure that your
valuable data won't be saved on places which are bad or about to
turn bad. FMT will try three times too. The difference is that
if FMT fails to access a sector in the first try it will mark
the sector bad and tell you how many tries has failed.

CLN is a utility to make full use of cleaning kits sold by 3M,
Memorex and other companies.
Without CLN, all you can do is to use commands such as DIR to
get the disk drive moving and bring head into contact with the
cleaning disk and the cleaning solution on it. However, there
are two problems that only CLN can help you.
Firstly, how many DIR commands you need to keep typing to keep
the disk head in contact with the cleaning disk for 30 to 60
seconds? With CLN you only need to type CLN to start and press
the ESC to end the process, no keystrokes in between. CLN also
"reads" both sides of every "track" to make full use of your
cleaning kit. Try CLN once and you will know how many keystrokes
it can save for you.
Secondly, since there is no data on the disk DOS will stop after
it fails to access the first track. This means you may only be
using 0.625% of the surface of your cleaning disk! (There are 80
tracks on a high density drive. Each track has two sides and you
are only using one side on the first track.)
CLN not only forces your system to keep on "reading" different
tracks on the cleaning disk and thus clean the head more
thoroughly but also provides you simple and easy ways to verify
that it does what it claims. Your will have the confidence that
you give your diskette drive the best care possible.

CHDK (CHECK DISKETTE) is a utility which gives detailed
information about a diskette. It shows you the information
contained in the system area of the diskette, check the
integrity of the system area, gives you detailed layout of
system area, root directory and data area and then give you a
report of the fragmentation on the diskette.
The program also shows you other important or interesting
information about a diskette. For example, it shows you the
sectors, clusters and tracks with active data, the software who
formatted the diskette, maximum number of root directory entries.
CHDK shows you lots of information packed in one screen.
