I hope this is the last BETA version...
NEWS:
- detection of USB devices:
1. You can use the USB ASPI driver.
But it doesn't work on some chipsets.
2. On some new PC's/notebooks with BIOS support of USB legacy devices
will BIOS detect these devices (must be connected before power on PC!)
with INT 13h support and therefore you don't need load any
USB ASPI driver.
In this case the USB device should be detected via INT 13h and get
the name 'USB (XXh)', where XXh is the assigned BIOS number for INT 13h.
If you load USB ASPI driver too, this device will be detected twice,
first via INT 13h and second via USB ASPI. This is not an error,
you can use both devices.
For USB device detected via USB ASPI you can get more information
than with INT 13h.
- CD ISO image: new boot procedure supports SATA CD/DVD devices

- new item 'Check DCO structure'
- SMART:
- new menu 'SMART Command Transport (SCT) Menu'
- new SMART log 'SATA Phy Event Counters (11h)'
- added new SMART attributes
- new menu 'SATA Commands'
- new command line options ('HDAT2 /?' or 'HDAT2DEM /?' for help):
- /G=<drive>:\[<dir>\[<name>]]
- Set path/name for BIX file (FAT only)
- this input/output path is used for DEBUG BIX file
- this option is valid for demo program HDAT2DEM.EXE only
- /O=<drive>:\[<dir>\] Set output path for save (FAT only)
- this output path is set for saving all the text files
Examples:
1. /g=c:\hdat2\hdat2my.bix
2. /o="c:\hdat2\hdat2my.txt"
CHANGES:
- file name for screen error output is changed from HDAT2ERR.SCR
to HDAT2SCR.ERR
- SMART messages are changed: there are four SMART messages.
Because a SMART command get status returns two values only
(good or bad status), I added two new values (error and warning).
1. ALERT (red color)
- this value is set from SMART command
- T.E.C. (Threshold Exceeded Condition) is detected;
basically it means a disk failure.
2. ERROR (red color)
- erroneous attributes 5,196-198,201,220
3. WARNING (yellow color)
- erroneous attributes 199-200,202-203
4. O.K. (green color)
- this value is set from SMART command
CORRECTIONS:
- corrected error if you changed output path to root of drive
- corrected error 'access denied' on saving file
- corrected error of BIOS DMI decoding
01.07.2008 4.6 beta 2
Beta restrictions:
- device access PCI DMA is disabled
- device tests are still DISABLED!
What is new in BETA program:
- CD ISO: new boot procedure
- new drivers for PATA and SATA CD-ROM
- some new ASPI drivers
- some corrections for PCI and SATA detection
- parameter /W (Wake/Spin-up) is tested and works
(when the feature 'Power-up in Standby Feature Set' is enabled)
- SMART messages are changed: there are three SMART messages
1. ALERT (red color)
- T.E.C. (Threshold Exceeded Condition) is detected;
basically it means a disk failure
2. ERROR (red color)
- check attributes 5,196-198,201,220
3. WARNING (yellow color)
- check attributes 199-200,202-203
- demo version HDAT2EXE has a new parameter:
/G=<drive>:\[<dir>\[<name>]] Set path/name for BIX file (FAT only)
you can save a DEBUG BIX file of your hard drive and then with this
command line option you can load it like demo
- new command line option ('HDAT2 /?' for help):
- /O=<drive>:\[<dir>\] Set output path for save (FAT only)
- this output path is used for saving all the text files
Example: 1. /O=c:\hdat2\hdat2my.bix
- Processing of command-line parameters is sequentionally, see below.
If you want to redirect the output of command line options help to a file
HDETECT.TXT, use this command:
X:\>HDAT2 /L /?
On the contrary this command will show command line options help only,
but will not save it into file HDETECT.TXT:
X:\>HDAT2 /? /L
