- WHAT'S NEW?
-
- IMPORTANT: Caching floppy drives slows POLYCOPY's performance. If you
- are using SMARTDRV.EXE, use the following syntax to disable
- floppy caching:
-
- SMARTDRV A- B-
-
- The statement above assumes you have two floppy drives. Other
- cache software should have similar options if floppy caching
- is supported.
-
- [VERSION 3.00] - Up to 30% speed improvement. This was accomplished by doubl-
- ing up on the block size of each disk read or write. A very
- positive side effect was to reduce the XMS handles requirement
- by 50% over previous versions. Faster computers show the most
- significant improvement. For example, on a 33Mhz or faster
- computer 1.44MB diskettes copy in about the same amount of
- time as 720K's.
-
- - New simplified syntax. In earlier versions of POLYCOPY, image
- file syntax was a bit confusing. The new syntax vs. the old
- is as follows:
-
- OLD: POLYCOPY [src<:>] [tgt<:>] [/i<s|r>:fspec] [/f] [/x] [/t] [/v] [/r]
- NEW: POLYCOPY source [target] [/f] [/t] [/s] [/r] [/x]
-
- EXAMPLES OF NEW SYNTAX:
-
- D>polycopy b: /f
- C>polycopy a: b:
- C>polycopy d:\temp\disk1 b: (default = ".FLP")
- C>polycopy e: disk1.flp
- C>polycopy /r (print registration form)
-
- As compared to the old syntax, image file handling is now much
- more intuitive. Simple, type SOURCE and TARGET and POLYCOPY
- will determine whether each is a disk or image file
- automatically.
-
- - Improved formatting. With the new format capability (MS DOS
- 4.01, 5.0 and 6.0 only), there is no longer any need for human
- intervention during the format operation. No doubt about it,
- the additional carriage returns and having to respond to
- "Format another (Y/N)" was a real pain. This and other such
- ambiguous prompts have been removed.
-
- - Reduced XMS handles requirement. This version requires half
- as many XMS handles as all previous version to copy the same
- number of cylinders. It should only be necessary to set the
- maximum number of available XMS handles to 64 now, rather than
- 128 as before.
-
- - Support for 2.88 MB floppies (untested).
-
- - QEMM Detection. Useful if you like knowing what is active
- during copies.
-
- - Disk counters. This version keeps track of the number of
- diskettes read and written, so you don't have to. The numbers
- appears in the following form:
-
- Source disk -------, ,------- Target disk (always "1")
- | |
- 100 percent of disk 4-1 read ==>
-
- 75 percent of disk 2-5 written ==>
- | |
- Source disk -------' '------- Target disk
-
- where the number "1" or "3" is replaced by the actual diskette
- currently being read or written to.
-
- - Beep tone. Using the environment variable POLYSOUND, you
- may now tell POLYCOPY whether or not to produce an audible
- beep after each diskette has been processed. It defaults to
- being turned on. Use the following syntax in you AUTOEXEC.BAT
- or from the DOS command line to turn it off always:
-
- SET POLYSOUND=OFF
-
- You may also use the "/S" command line option to toggle sound
- on or off. Like "/T" for toggling TrashGuard, "/S" sets sound
- to on if it is already off (or off it is is already on). For
- example, if the environment variable POLYSOUND is not init-
- ialized, a "/S" will turn beep sounds off -- except for
- warnings.
-
- - Reduced RAM overhead when copying any floppy smaller than
- 1.44 MB, or when the "/V" verify option is not selected.
- Dynamically allocated sector buffers, rather than static,
- make this possible.
-
- - Improved image file path correction. In previous versons if
- you specified an image file with a filename larger than the
- eight characters allowed by DOS, POLYCOPY didn't not display
- the truncated path as it was actually used. This primarily
- affects what is displayed rather than what is used.
-
- - Improved exception handling. Earlier releases attempted to
- format diskettes regardless of the nature of errors detected
- during disk writes. Now, POLYCOPY tests for specific errors.
- For example, if a diskette is write protected, a "Disk write
- protected" error will be displayed and no format will be
- attempted.
-
- - Input character checking. When prompted for keyboard input
- for things such as "press ENTER" or "(Y/N)?", this version
- of POLYCOPY beeps until a valid choice is selected. Older
- release would accept almost any character, sometimes with
- unpredictable results.
-
- - Converted to use DOS' built-in VERIFY capability, rather
- than hard-coded. This reduces .EXE size and RAM overhead, and
- makes POLYCOPY even easier to operate than ever. The "/V"
- option has been removed; however, you can turn verify on or
- using using the regular DOS syntax:
-
- C>verify on
- or
- C>verify off
-
- NOTE: Disk writes are much faster with write-read-verify
- turned off. Most of the time it is not necessary to
- perform this extra testing.
-
- - TrashGuard now defaults to OFF. You may still use the "/t"
- command line parameter, or the "TrashGuard=" environment
- variable, to turn TrashGuard back ON.
-
- - Enhanced error recovery. In earlier versions, a bad
- destinate disk caused POLYCOPY to halt a duplication
- session. This has been changed now to give you the
- option to make additional copies, thus saving valuable
- time.
-
- - Force drive type option. In rare cases, such as with
- on systems with more than two floppy drives, it is
- necessary to force POLYCOPY to treat a floppy drive as
- a particular type. If POLYCOPY has trouble determining
- the correct drive type, use the "/DT=n" parameter to
- force a type. The drive type codes are (n=1...5):
-
- 1 = 360K, 2 = 1.2M, 3 = 720K, 4 = 1.44M and 5 = 2.88M
-
- IMPORTANT: Use this option very carefully. Under
- normal circumstances use should not use
- this option.
-
- [VERSION 2.81] - Version 2.80 has a bug that keeps it from creating the
- ORDER.FRM file, which is now corrected.
-
- - Fixed a cosmetic problem that occurred if the SOURCE and
- TARGET drives were not the same. The statement, "Writing to
- TARGET disk in drive...," shows up on the wrong line.
-
- [VERSION 2.80] - Corrected pointer problem that's been generating 90% of QEMM
- and other TrashGuard errors. Now you can truely use POLYCOPY
- and QEMM safely and reliablly together. Just don't forget to
- increase the number of handles to 128 (see below).
-
- [VERSION 2.70] - Read/Write elapsed time display. After a comlete disk read
- or write the elapsed time for the process is displayed in
- the form [XXm XXs], where 'm' is for minutes and 's' seconds.
-
- - TrashGuard<tm> RAM validation protection. Some EMM drivers,
- such as QEMM, can make dangerous modifications to DOS RAM
- without warning if they are not configured properly for your
- system. A change to a single byte will not affect most
- programs noticably; however, when you're copying diskettes
- a single byte error cannot be tolerated. Enter TrashGuard.
-
- TrashGuard does exactly what it's name implies, it guards
- against trashed data. An advanced 32-bit CRC algorithm is
- used to detect changes to diskette data while it is stored in
- RAM.
-
- - Verify option. In verify mode POLYCOPY does in verify mode
- is to read each track written to disk and compare every byte
- to insure an absolutely accurate write.
-
- - No more erroneous "Drive not supported or is not a floppy
- drive" errors. If you get this error now chances are it is
- legitimate.
-
- - Extended drive letters. This version supports any floppy
- drive letter -- including virtual drives. Letters such as
- those assigned by MicroSolutions' CompatiCard IV (i.e. E: F:).
-
- - DiskDUP (Copr. (C)1990 R. MacClean) image file compatibility.
- This version allows you to restore from DiskDUP's image files
- that are not compressed.
-
- - Tested with fast, single-pass copies on 600 rpm high-speed
- floppy drives.
-
- [VERSION 2.60] - Store to and restore from diskette image files. These disk
- images may be archived for modem transmission or simply stored
- on you hard drive for diskette recreation without the need for
- an original.
-
- NOTE: The image files POLYCOPY creates are completely
- compatible with those used by the PC Magazine utility
- pair 2FILE/2FLOPPY (C)1991 Ziff Comm. Co.
-
- - DOS 5.0 compatibility
-
- - Added "/u" parameter to the DOS FORMAT shell when DOS 5.0
- is detected.
-
- - Added "/x" parameter to disable XMS memory usage. This is
- primarily for testing and comparisons, but may also prove
- useful if you have XMS problems and don't want to go to the
- trouble of removing your HIMEM.SYS driver.
-
- - Removed disk status check when "/f" forced format parameter
- is specified. This eliminates the long pause associated
- with cross-formatted diskettes, but only if "/f" is specified.
-
- - Fixed bug that occurred when insufficient XMS handles resulted
- in a switch to DISK producing a corrupt target. It is still
- recommended that you install:
-
- "DEVICE=C:\DOS\HIMEM /NUMHANDLES=128"
-
- for the best possible performance (HANDLES=128 for QEMM).
-
- - Added "/r" parameter so POLYCOPY can now generate its own
- registration form. Use the following syntax to print a
- POLYCOPY registration form:
-
- C>polycopy /r > prn
-
- [VERSION 2.22] - Earlier versions skipped side one of the last track on high
- density diskettes. This has been corrected.
-
- [VERSION 2.21] - Fixed bug that occurred when copying multiple, different disks.
- The first disk always copied fine, but the program didn't
- reliably free up XMS and RAM prior to starting another disk.
-
- [VERSION 2.20] - XMS memory support!
-
- [VERSION 2.12] - Gives "WARNING!" rather than error when user attempts to make
- the default drive equal to either the SOURCE or TARGET drive.
-
- [VERSION 2.11] - Corrects formatting problem, "bad parameter," for DOS versions
- less than 4.0.
-
- [VERSION 2.10] - Multiple disk drives supported.
-
