MHDD
projectMHDD
works:The main difference: MHDD
does not use DOS or BIOS functions or interrupts and works even if the BIOS does not detect the drive. You can turn on your drive after DOS boots (A small risk of drive damage exists if you are not careful)MHDD
uses DOS ASPI driver (incuded). MHDD
from the hard drive that is on the same physical IDE channel (cable) you are going to use to diagnose drives! DOS (SMARTDRV.EXE, for example) may access any drive at the same moment as MHDD
. MHDD
does not work with Primary IDE as it usually used to boot DOS and run MHDD
./ENABLEPRIMARY
switch.(this is included in the CD image)MHDD
works with each physical drive separatelyMHDD

If you booted from the CD, MHDD
runs from a RAM drive, so this is not problem and AUTOEXEC.BAT
starts MHDD
with the /enableprimary
command line option. vi.exe
and pkzip would also be a good idea. Remember floppy is B:

.ID
or EID
commands.MAKELOG scans the surface of the drive and creates a detailed log file.If you booted from the CD there will, most likely, be insufficient space for the log file on the RAM drive. If the target drive is less than 10GB the log will fit on a floppy. To create the log on a hard drive : (this means there must be one with a FAT partition which you are willing and able to write to). (Here's a use for those old < 1GB drives you have laying around.)

SCAN or[F4] no logfile will be created |
A menu is presented to adjust Start and End LBA, Remap bad spots( Safe to data if there are less then 100 bad blocks.) change the Timeout for a single operaton DGG: I suggest you change Timeout to 5 loop (useful when small range is specified) Erase Delays(danger data will be lost). |
