Diskrw.com is a disk sector reading and writing program.
Dpit.com is a partition information management tool.
Dspt.com is a combined version of the above two.
I have been using dspt and rarely use diskrw, so I might mix up these parameters?

Finally found the tool to back up PBR

Thanks a lot, great stuff

What a good thing!
Just dsptw 0 /l /getid combined with For can do a lot of things.
If only the hidden partition can be assigned a drive letter it would be nice, please big, how to in the command line to achieve the hidden partition assigned a drive letter?

Let's see, is the last link the latest version?

Hero, can you update the DSPT for DOS? (Related to W32 amphibious)

There are two problems with dspt for DOS: Partition 12 is shown as unknow type, so it can't be unhidden either.
Also, Changetype is not supported.

Add a switch /GetID to display the partition ID value (applicable to /L and /find commands)

Usage:
dsptw 0 /l /getid

dsptw 0 /find:all /getid

Does this version support the version compatible with GGHOST's requirement to prevent anti-virus software from mistakenly killing? Is there any time limit for this version?

Because I am preparing to update to the next version of one-key GHOST.

I wonder if there is a relatively simple way to directly save the contents of an entire partition to a file?

Judging partition information is mainly applied in DOS. Hope the landlord will update the DOS version of dspt as soon as possible to make it have the same functions as the dspt Windows version. Looking forward.

There is a bug in the latest DSPT amphibious version:
Executing the following command under Windows can normally display all partition information, but it cannot be displayed under DOS
dspt /a /pdr

Good tool. Thanks the LZ!

Not easy, it's too powerful

Very good stuff... Keep up the good work... Thanks

The number of total sectors is 1048576. The last sector is 1048576 - 1 = 1048575. So 1048575 is obtained by subtracting 1 from the total number of sectors which is 1048576.

For the part about how to subtract 1 in DOS, in DOS you can use some batch processing methods. For example, if you have the number in a variable, you can use arithmetic operations in batch scripts. But generally, DOS has limited arithmetic capabilities compared to modern systems. However, you can use external tools or write simple batch logic to achieve the subtraction. But the specific implementation depends on the exact environment and the way you are handling the data.
