The result of dspt 0 /l is as follows

Disk Partitions Cylinders Heads Sectors TotalSectors Mbytes
0 1 1040 16 63 1048576 512

No. Drv Type Volume P ...

The sector numbering starts from 0. According to the above result, the total number of sectors is 1048576, so the sector numbers should be 0..1048575, and the number of the last sector should be 1048575

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

You check the help information of dspt under DOS. I don't want to always have some boring questions disturbing me

What a good thing!
Just the combination of dsptw 0 /l /getid with For can do many things.
It would be great if we could assign a drive letter to the hidden partition.
I'm a newbie, maybe I'm wrong. Excuse me, sir, how can I assign a drive letter to a hidden partition from the command line?

In a win32 environment, you can use the changetype command to achieve this.

Dude, can you update the DSPT for DOS? (Amphibious with W32)

There are two problems with dspt for DOS: Partition 12 is shown as unknow type, so it cannot be unhidden either
In addition, Changetype is not supported.

Please be patient, I will add this function soon.

Does this version be compatible with the version that GGHOST requires to prevent false positives from antivirus software?
Does this version have a time limit?

Because I am going to update to the next version of One - key GHOST.

1. No time limit
2. Because there are assembly parts in the source code, it needs to be adapted into a C program, and it is not temporarily compatible with the anti - false positive requirements of GGHOST.

Hehe, thank you for the reply! Regarding the number of sectors, I do know it.

The situation is like this: There is a software that writes the KEY into the last sector,
but after restarting the computer, the KEY is gone
I just want to make a batch processing to back up the KEY,
and write back the KEY when restarting.

But I'm not good at it and can't figure it out

The following is my batch processing for backing up the KEY:
dspt 0 0 1 /s 0.dat /y Back up sector 0 to 0.dat
dspt 0 /dpr /y Write the last sector to sector 0
dspt 0 0 1 /s K.dat /y Back up sector 0 to K.dat
dspt 0 0 1 /r 0.dat /y Restore sector 0

It's not that I'm an idiot, I want to make it universal because the number of sectors in each computer is uncertain,
I also don't know how to get the position number of the last sector,
so it's so troublesome,
This requirement is relatively special!
I just want to ask, who has a pure DOS calculator?
For example:
calc 1024-1
Get 1023 is okay

I've been using dsptw.exe all the time, and it works well with the program. Thanks a lot, heh.

There are some special operations that require setting the partition as inactive, but currently DSPTW only has the function of activating. I wonder if a function to deactivate can be added? Heh.

Actually, it's just that a friend accidentally found out that when booting from a USB flash drive, it's not necessary to activate the partition. Activation actually causes a series of problems. But HP's formatting tool sets it as active by default, so I want to use dsptw to achieve this function. If it can be added, I'll be very grateful, heh.

Thanks for the update, I'll download and test it.

Does DISKRW support 640G hard drives?

It can support up to 2T (2048G) hard drives

Very good tool. Thanks.

Thanks to the LZ for sharing, I've been using it all the time. I'm coming to support the LZ today, heh heh
