-
- > I've already sent a postcard to you for an older version. Do I have to
- send another one for the update...?
-
- Of course not. Except if you want to tell me something important.
-
- > I'm short of money... is a email message sufficient instead of a postcard
- for HD-Copy?
-
- You must be joking. A postcard isn't that expensive. Don't be lazy, buy a
- nice postcard and a stamp, write my address and something like "I love
- HD-Copy" onto it! Well, you may send me email, but I really prefer
- postcards. I just read email and then delete the message, but of course I
- keep the postcards.
-
- > I'm interested in the source code of HD-Copy.
-
- Sorry, but I'm not distributing the source code. I just don't want hacked
- versions of HD-Copy floating around.
-
- > How about reading from drive A and writing to drive B simultaneously,
- without buffering?
-
- This is only possible if you've got two separate disk controllers. Since
- very few people have these (I don't know anybody), HD-Copy doesn't support
- this special mode of copying.
- There are copy programs which claim to read and write simultaneously (using
- only one controller), but this is definitely NOT POSSIBLE. To mention some
- reasons, there's only one DMA channel per controller, and the floppy disk
- cable/connector has only one wire for both reading and writing. Those copy
- programs read and write each track one after another (read track 0, write
- track 0, read track 1, write track 1, read track 2, etc.) while keeping the
- other drive's motor and LED on, so it seems to be active, but actually it
- isn't. There's no advantage in time doing this. It's just a deception.
-
- > How about SmartDrive? Does it work or does it not? How about HyperCache,
- Norton Cache, Combi-Disk, ... (insert your favourite cache program)?
-
- That can't be said for sure in every case.
- I've tried HD-Copy with SmartDrive 4.0 (the version shipped with Windows 3.1)
- for some time without any problems. Also, COmbi-Disk v1.13 doesn't cause any
- problems, because it doesn't support floppy disk caching yet.
- Some of my friends use HyperDisk under DOS 5.0 without trouble. I think most
- cache programs will work, but I can't guarantee anything.
- Another user of HD-Copy tried it with DOS 6.0 and SmartDrive, and it did FOT
- work. So be careful, do some test copies if you're not sure about your cache
- program.
-
- > I've written a disk using the password option. Well, I forgot the
- password... Is there anything one could do?
-
- Well, I'm the author of HD-Copy, so I know how the password protection is
- working, and of course I'm able to override the protection and get your data
- back. BUT I WON'T DO THAT.
- Why? Because a protection that is circumvented is no protection anymore.
- There's no way to tell for sure that the data an that disk are yours, so
- maybe I would help you cracking somebody else's disk!
- Sorry if you really forgot your password. Better keep it in mind next time!
-
- > It would be nice to be able to use the mouse for those yes/no questions,
- too.
-
- No. Those questions appear at somewhat "critical" places, and if you miss
- the desired field by mistake (this can easily happen if you're using the
- mouse). It's safer to use the keybord.
- Besides you can avoid yes/no questions in general by switching the "expert
- mode" on.
-
- > I tried to run HD-Copy under Windows...
-
- HD-Copy may not run reliably under Windows or environments with multitasking
- capabilities.
- Why? HD-Copy uses its own memory management, DMA and interrupt management.
- Most multitasking systems (and Windows, too) try the same, which might result
- in conflicts (or even a crash).
- No, I'm not going to write a Windows version of HD-Copy, because Windows'
- resource management is simply too slow. For example it's not possible to
- program a direct DMA access under Windows.
-
- Last minute note: some people reported that they got HD-Copy to work under
- OS/2. Try it on your own risk. Perhaps I will write an OS/2 version, which
- might be slower than the DOS version, but that doesn't matter much in a
- real multitasking environment.
-
- > The opening sound is really annoying!
-
- Turn off "Sound fx" in the options menu, then "Save configuration" in the
- special menu. That's it.
-
- > How reliable are those special formats (more than 1.2 Mb on 5 1/4 and
- more than 1.44 Mb on 3 1/2 drives)?
-
- They're as reliable as any standard format. There's one restriction: some
- very old disk drives can only cope with 80 tracks maximum. You have to
- format only 80 tracks on those drives (resulting in 1.68 Mb instead of
- 1.722 Mb using 82 tracks).
- There are rumours that the magnetic layer of some "no name" disks only
- reaches track 80, but I tried lots of different disks, and I've never had
- any problems with them. However, I recommend using disks of well known
- manufacturers (3M, BASF, Verbatim, Scotch, Fuji etc.).
- About compatibility: I've never had a program which did not accept a disk
- with a special format. Even compress tools, "disk doctors", and disk editors
- work (for example, Norton's tools, or Central Point software / PC Tools).
- Some modern BIOSs don't even need the FDREAD program to be able to use
- those disks.
-
- However, do NOT use utilities which format disks with more than 10.5 Kb per
- track (i.e. more than 1.76 Mb capacity), because they are very unreliable.
- Especially don't do that for storing important data, like backups, archives,
- savety copies etc.
-
- > I get lots of read and write errors, at random places!
-
- You should try cleaning your disk drive. There are wet cleaning systems
- available in most computer stores, they work perfectly with HD-Copy's
- "Clean disk" function. Refer to the manual for more information.
-
- Another thing I must mention: Don't misuse DD disks!
- There are people drilling HD holes into DD disks, using them for 1.44 Mb.
- DON'T DO THAT! It may work for a while, but since DD disks have another
- magnetic coercitivity than HD disks, the tracks will start melting into
- one another. This may happen after a week or after a year -- but it WILL
- happen!
-
- > I've got HD-Copy X.Yz. Is there a newer version? If yes, how can I
- get it?
-
- Via the Internet or on a disk (by mail). Refer to the manual for more
- information.
-
- > I've got some interesting software... games and such... you know.
- Do you want to swap software?
-
- NO.
-
- > HD-Copy is great! Why isn't it shareware?
-
- Most people wouldn't pay anything anyway, so I made it "cardware".
- I you'd be willing to pay a shareware fee, then how about sending
- a postcard instead? I won't keep anybody from sending money or
- anything else, though...
