How to Use Diskpart.exe to know the Active Partition
sayan
problem using Diskpart.exe in Windows XP to know which is my active
partition and what drive letter has been assigned to it and in which
physical disk resides this partition.
I've progressed this much with my effort, i don't know if there's any
mistake in batch syntax as well as logic. But i couldn't advance
beyond. I've one physical disk currently and it has 4 primary
partitions, out of which partition 2 is currently active and i'm
posting here by booting my XP into Partition 1. I've windows xp
installed in both partition 1 and 2.
My progress:
@echo Off
setlocal
If exist partinfocmd.bat del /q /f partinfocmd.bat
echo list disk > disklist.txt
diskpart /s disklist.txt >> diskdata.log
for /f "tokens=1-4 skip=8" %%B in (diskdata.log) do (
set DisknuM=%%C
echo select disk %%C > gpartcfg.txt
echo list part >> gpartcfg.txt
echo diskpart /s gpartcfg.txt ^> gpartcfg.log >> partinfocmd.bat
)
call partinfocmd.bat
for /f "tokens=1-4 skip=8" %%B in (diskdata.log) do (
@for /f "tokens=1-8 skip=10" %%O in (gpartcfg.log) do (
echo select disk %%C
echo select part %%P
echo detail part
)
)> partstat.txt
****************************************************************************
Now partstat.txt contains following:
select disk 0
select part 1
detail part
select disk 0
select part 2
detail part
select disk 0
select part 3
detail part
select disk 0
select part 4
detail part
****************************************************************************
I'm unable to parse output of diskpart /s partstat.txt.
Please help.

If you shows us the output and what you want to extract then it might be
easier...

In this output only in case of Partition 2 there is an output called
Active: Yes, while in case of other partitions the result is Active:
No. I need to know the Partition No. firstly, then correlate that no.
with Drive Letter Assigned to it.
thanks foxidrive.

AFAIK the active Partion is always C in DOS - XP. (I don't know Vista)
as to which partion number this is, I don't know.
Here's an idea:
list the partitions, then do for each Primary (only these can be active I
believe)
select the partion and detail it to a temp file, Find "Active: Yes". if so
you have your Active Partition.
I had to force the disk admin service to start each time - I don't know
why. This slows it down considerably.
@echo off
echo select disk 0 >~dpa.txt
echo list part >>~dpa.txt
net start dmadmin >nul
diskpart /s ~dpa.txt >~dpb.txt
for /f "skip=9 tokens=2,3" %%A in (~dpb.txt) do if /%%B/==/Primary/ call
:chkpri %%A
rem del ~dp?.txt
goto :eof
:chkpri
echo select disk 0 >~dpx.txt
echo select part %1 >>~dpx.txt
echo detail part >>~dpx.txt
net start dmadmin >nul
diskpart /s ~dpx.txt >~dp%1.txt
find "Active: Yes" <~dp%1.txt>nul
if not errorlevel 1 echo Active Partition is %1
