Now in the beta version, there are only two files, and there is no win32 version of dpit. So I ask if there are any differences in the new version. diskrw is still part of dsptw. It's just that some people like diskrw, so I simply released the win32 version. I will organize the win32 version of dpit when I have time. [ Last edited by 19951001 on 2007-6-21 at 08:56 PM ]

If the program treats all zeros as the end of the partition table entry, it can only back up one partition table entry. I think the Gotomsdos program made this mistake.

The reason for such expectations is also because of the reasons mentioned above, and also because under DOS, the detailed information (such as size) of the NTFS partition cannot be obtained. Also, it is wanted to be used to judge multiple hard disks. Although MINITO can do it, if it is not in real mode, parameters must be added, then the hard disk parameters cannot be obtained and there is no way to choose. So now I first use GDISK to get the hard disk information to intuitively select the hard disk to be operated (if there are multiple hard disks), and then run MINITO. There is no other meaning, just wanting to make GHOST under DOS more convenient!

The DOS version of DSPT cannot correctly display the label of the TRUEIMAGE safe area. The partition flag is 0XBC. Changing it to 0X1B can correctly identify the label of the safe area. Please correct it.

Now the GHOST image is placed in the ACRONIS secure zone, and one - key recovery is perfectly coordinated.

By the way, friends who have HPA, after UNLOCK, can DSPT correctly display the volume label?

G:\usbhdd>DSPTW.EXE f: /pdr /Y 2:1 G:\>DSPTW.EXE f: /pdr /Y > drv.txt The system cannot find the file specified. Part of the command line results output of DSPTW.exe cannot be redirected to a file or variable... The problem I am encountering now is that the post-processing cannot be carried out...

Tested: The total number of sectors of the hard disk detected in dspt is inconsistent with that detected in dsptw. There is an error in dsptw detection. Please correct it. [ Last edited by hlytg on 2007-7-12 at 04:24 PM ]

[ Last edited by hlytg on 2007-7-12 at 04:24 PM ] dspt uses the extended Int13 to obtain the number of disk sectors. dsptw uses deviceIocontrol to obtain the total number of sectors in the win32 environment. There is a certain error. The maximum error is 255×63 sectors, which is 7.8M. I have explained this error in previous posts. [ Last edited by 19951001 on 2007-7-12 at 11:18 PM ]
