Tried it. Only the latest DOS version has this function, while the WIN32 version doesn't. I wonder how to achieve it?

The following software can be used in combination to achieve it:

diskrw 0 0 ?? /r 1.exe

Regarding the issue of writing files, the sector parameters are too rigid. It has to be exactly consistent with the file's sectors to write. The problem is that the number of sectors in the file is sometimes difficult to calculate (or is uncertain). Can this parameter be modified or canceled, or when set to 0, can it default to writing according to the file length (automatically calculate sectors)?

Wait...

In DSPT, the /e

DSPT
/E: Clear Disk Sector Info

This is of course to clear the sector content, what you said is correct, what's so strange about this.

In DOS, you can write part of a sector, and it doesn't require writing the entire sector

This is correct,
But I am using a combined version of dspt and diskrw,
And the /E parameter of diskrw is for modification:
2008.9.27
Win32 version diskrw updated
http://upload.cn-dos.net/img/798.rar

The content of this modification:
1 Command adjustment, the original /E command (delete sector content) is changed to /F command (sector content filling)
The original /E command fills the specified sector with 0
The current /F command can fill the sector with any value. If no Value is entered, it performs the same function as the original version's /E command

DISKRW
/F: Fill Disk Sector Info with Value
Value: an Integer (0..255), default is 0

2 Command adjustment, change the command to modify the sector from the original /M (Modify) to /E (Edit) for more intuitive

DISKRW
SectorNo: Absolute/Relative Sector No. of Disk
Offset: The Offset in Specified Sector (0..511)
/E: Edit Disk Sector Info
/HEX: Hex Style
Value: Hex Digital String (No more than 32 characters)

So, can we unify the parameters?

In addition, please take a look,
str 1.exe 0x03 0 /e /hex:0011
An error occurs when writing 00. Later, when I used the E parameter of dspt to write, I found out that it was to clear the sector.

http://upload.cn-dos.net/img/7 ... In the new version of diskrw, the modification command has been changed from the original /M to /e But it has never been changed in dspt. When you use /e in dspt, the program will also ask you whether to clear the sector content, haven't you noticed. I have never released any combined version of dspt and diskrw [ Last edited by 19951001 on 2008-12-22 at 20:10 ]
