Changes in 1.0.1.9 [refresh 2] (5/1/07)
---------------------------------------
- UPX no longer used to compress installer, to avoid virus false-positive


Changes in 1.0.1.9 [refresh] (27/12/06)
---------------------------------------
- Single installer for both x86 and x64 platforms
- Added support for Windows Vista
- Driver code unchanged in this release, so no version number change


Changes in 1.0.1.9 (7/5/06)
----------------------------
- A motor timeout of 0 seconds can now be used to prevent the motor switching off


Changes in 1.0.1.8 (30/3/06)
----------------------------
- Fixed short-write start race condition on SMP/HyperThreaded systems


Changes in 1.0.1.7 (15/3/06)
----------------------------
- Fixed legacy FD_SCAN_TRACK use, which sometimes needed recalibration before seeking
- Fixed raw reads failing to start if the request size was above the DMA limit
- Fixed possible crash if control device was open during driver restart/update


Changes in 1.0.1.6 (12/3/06)
----------------------------
- Fixed large raw-read transfer crash on AMD64
- Fixed track wrap error in layout scanning when first sector is close to index hole


Changes in 1.0.1.4 (8/3/06)
---------------------------
- Added raw track reading support using Disk2FDI's 2 drive method
- Fixed acquire-only commands holding on to the controller if motor was off


Changes in 1.0.1.2 (5/2/06)
--------------------------
- Changed default motor timeout to 2 seconds
- Default controller settings are now restored for each device handle
- Controller now locked when device open, so manual lock/unlock are deprecated
- Recalibrate and Seek commands no longer require a disk in the drive
- Read/write commands now use caller-specified buffer for size codes > 7
- Fixed access to sector id 255, which was returning ERROR_INVALID_PARAMETER
- Fixed crash when reading/writing sectors with size codes >= 32
- Fixed possible crash if device was in use across a driver restart/update
- Fixed Configure and Specify commands, which checked the input buffer against pointer size instead of structure size!
- Missing data field is now reported as ERROR_SECTOR_NOT_FOUND instead of ERROR_CRC
- ReadId now resturns ERROR_CRC for CRC errors, instead of reporting as ERROR_SECTOR_NOT_FOUND
- Improved index sync, for better support of small sector sizes and early track starts
- Updated header to use only fixed size types, for 64-bit compatibility
- Removed cyl value from FD_SCAN_PARAMS structure, but still allow old-style calls for compatibility
- Added head tracking for safer seek bounds checking
- Added sector sync for duplicate sector id support
- Added support for custom head-settle times, for optimal use of modern drives
- Added support for reading count of unprocessed controller data
- Added timed track scanning to allow sector positions to be determined
- Added short-write support for truncated sectors, CRC errors, weak sectors, etc.
