- Introduction
- ------------
- SuperCopy is a freeware disk copy tool with some special features.
- It can be started via WB or CLI just as you like. Nothing special
- is necessary. The program needs only KS1.3 and is multitasking
- friendly. That means that you can copy disks while doing another
- thing on another screen.
- If you have only 1 drive, then the program tries to allocate as much
- memory as possible to avoid disk swapping.
-
- Working with SuperCopy
- ----------------------
- The whole program is more or less selfexplanatory but some functions
- has to be explained bit more.
-
- IMPORTANT:
- You have to write protect your source disk for copying, otherwise the
- program is only telling you, that the source disk is not write protected!:(
-
- After any message you have to type 'Retry' or 'Cancel'. No automatic
- recognition of 'disk inserted' is build in. That's not because I like
- to improve your skill in clicking around :), the reason is the following:
- The program is multitasking friendly, as I told before, therefore the
- disk interrupt is not enabled. When you insert a disk the system tries
- to read the directory of this disk into the buffer, if I would have
- installed the recognition of 'disk inserted', the program would try
- to read cylinder 0 at the same time. Then the heads had to move fast
- between cylinder 0 and 40 until the dir is read. I think it's better
- to wait those few seconds and then start the copy. The drive will thank
- you with a longer lifetime.:) That you should have in mind when you
- start a normal copy, too.
-
-
- Source and Destination Drives:
- ------------------------------
-
- Should be no problem, just click from where to where the copy should go.
- You can select several destination drives but only one soure drive. The
- program will not allow that. Drives which are not connected will not appear
- on the screen. If you have enough memory free, a bit more as for one disk,
- then a 'RAM Gadget' will appear. This is very useful if you want to make
- multiple copies of one disk. Copy the disk to 'RAM' RAM=destination and
- then you can copy from 'RAM' to all drives you have connected.
-
-
- Selection:
- ----------
- You can choose between 'Disk Copy', 'Disk Compare' and 'Check Disk'.
- The option 'Compare Write' is only for 'Disk Copy'.
-
- How can I activate the options 'Verify'? you may ask. Use 'Compare Write'
- instead it's doing the same thing and a bit more. That bit more is what
- makes the name of the program, SuperCopy = super safe copy! :)
- If this option is enabled (default), you can disable it, but then you don't
- have any guarantee that your copy is OK, it's only faster. If you want
- faaaast copies, this program is not for you. Use a faaaast copier instead,
- but don't blame anybody later if your copy is for the trashcan.
-
- A disk copy of a normal DD disk without compare lasts about 1 minute,
- with compare 2 minutes. But when you want a safe copy, one you are shure
- that the copy is the same with original, and I think that's more important
- than speed, then this is the right program for you.:)
-
- Well, what does that 'Compare Write' anyway?
- To explain this to you, I have to tell more about the copying process, as
- e.g. the diskcopy program of your Workbench Disk is doing it.
- Each diskcopy program is reading a Block, Sector, Cylinder or any other
- part of the source disk into a buffer. Out of this buffer the same part is
- written now to the destination disk. When you don't have 'Verify' activated
- the next part follows, no check of the written datas is performed. And if
- the dest disk has a hard error? Then the copy failed! But you don't know,
- no check was performed. OK, then we will use 'Verify'. What is that doing?
- When you have 'Verify' enabled the program tries to re-read the just written
- part on the destination disk, and if that fails you get 'Verify Error'. But
- who tells you that the datas are OK? You only know that the Block, or
- whatever part is written, can be read. Now we will use 'Compare Write'!
- SuperCopy reads 1 Cylinder of Data from the source disk in a buffer
- and writes it then to the destination disk.(nothing new under the hood)
- Now this Cylinder is read again into !!! another buffer !!! (verify), and
- then SuperCopy COMPARES the two buffers !!! Byte by Byte !!! If there's only
- 1(one!!) Byte of difference, SuperCopy will tell you and abort the copy.
- What are you doing with a bad copy anyway? Got the point? ;)
-
- The option 'Disk Compare' does just the same thing, only without copying.
-
- Check Disk is for reading the disk only, to check, if there's any trackdisk
- error on the disk, no DOS check, use DiskSalv (Copyright by Dave Haynie)
- instead.
-
- If you want to copy only some Cylinders just click on the arrows for
- Start- and Endcylinder.
-
- Start = start the action :)
- Default = set back to the default settings
- Source Name = read the name of the disk in the source drive
- The End = the end :)
-
- Limitations
- -----------
- SuperCopy copies only standard Amiga DOS and NDOS disks.
- Only from Cylinder 00 up to 79. No HD-Disk, no copy protected
- game disk and other crazy stuff.
- No MSDOS-, no ATARI-, no Macintosh-Disks.
-
- Known Bugs

- None known.

- Future Work
