Whatsnew. (most important improvements)

4.0
 + Small fixes
 + cwsdpmi.exe not needed from now
 + ITE8212 IDE controlled added
 + CX now show average latency (seek+read one sector)
 + erase: speed increased up to 50mb/sec and even more
   when used on controllers which support UDMA by BIOS
 + erase: current speed display
 + SiS IDE controllers added
 + SMART: RAW-values fixed
 + Promise controllers detection fixed

3.9 
 + Range Check error when selecting a drive fixed
 + Fixed Serial ATA conrollers detection (Via and SiI)
 + Intel ICH5 Native Mode detection fixed
 + CRITICAL: FF/TOF procedures fixed. Data was written into 
   wrong place on LBA48 drives
 + CRITICAL: fixed a bug when MHDD locks the drive when launching
 + CX now make SEEK+READ instead of just Seek
 + AAM now make SEEK+READ too
 + Scan: logging fixed
 + Timer functions has been completely rewritten
 + Scan: Timings changed to make better picture on latest drives
 + MHDD requires Pentium from now
 + CRITICAL: great speed improve on ERASE, FF, TOF and READ 
   procedures
 + BIOS support added. Erase now will go via bios if the drive
   correctly detected by BIOS. You can switch this off by 
   /DISABLEBIOS command line parameter
 + PWD, UNLOCK, DISPWD procedures fixed 
   (just cosmetics and reporting)

3.8
 + RPM procedure fixed
 + Keyboard procedures rewritten
 + Menu control procedures rewritten and optimized
 + Help system completely rewritten
    * Context help in the status bar
    * Command autocomplete on TAB key
    * F1 (Help) completely new
 + BSOD rewritten :-)
 + NVidia SATA/PATA controllers added

3.7
 + Fixed a bug running from write-protected media
 + Fixed bugs running on systems with HPT controllers
 + Fixed PCI module (several errors which fails mhdd)
 + Makebad/Randombad commands are back
 + Several checks added to improve stability
 + SCAN: Timeouts logging fixed

3.6
 + PCI bus scanning: several changes to improve detection of PCI cards
 + Registers "sticking" fixed :-)
 + ERASE: fixed small bug
 + SCAN: logging improved (statistics added)
 + SCAN: current/max lba numbers are "formatted" now
 + Optimized output somewhere and also optimized some procedures

3.5.2
 + Some insignificant fixes in SCAN procedure
 + CLRMBR command added (clears MBR)
   It backups MBR into two places: file LBA0.MBR and LBA 1 on your drive
   before erasing.

3.4 
 + Timer improved (10 times more precise now)
 + /RO key added to prevent MHDD to try to save any file
 + TOF and READ: changed algorithm of detecting error LBA number
 + VIA IDE controllers recognition fixed

3.3 
 + Intel ICH5/6 Native Mode SATA controller support added.
 - Slave devices have been disabled.
 + New command line parameter: /ENABLEPRIMARY
 + VIA VT6420/6410/RAID controllers added.
 + Several fixes.

3.2
 + Added sound alarm "on finish" (erase, ff, tof).

 + Fixed a bug with reading from registers.

3.1
 + Compiler has been changed to 32-bit  FreePascal  +  Completely
   rewritten module which works with PCI ATA controllers.  Serial
   ATA now also supported

 - CHS support removed

 + LBA48 support added + Fixed a  bug  with  COPY  routine.  When
   source  drive  hangs,  then  only  zeroes  is  written  to the
   destination drive

 + Program activation added to be sure that user  have  read  the
   documentation

 + Program  could  be run from write protected storage (with some
   limitations)

 + Erase  procedure  updated

 + Smart attributes <F8> will  autimatically  turn  SMART  on  if
   necessary

3.0
 + Rewritten config file management.  Running from  floppy  quite
   faster now.

 + Fixed  "erase" procedure.  Now fills with zeroes

 + Actual time during scan

 + Fixed division by 0 in copy/read/scan procedures

2.9.3.2 (Sep 2004)

 + Smart attribute names updated.

 + TOF procedure rewritten,  now skips bad blocks, makes detailed
   log file.

 + EraseWaits counter.

 + More precise logging (using flush  procedure  now  to  add  to
   logs).

 + Fixed some bugs in scan/copy/read.

 + Clean up the source...

 - CoProcessor emulation removed.
