How to get the volume size from a driveletter

[Jabeen]

Hello
I'm experimenting to make a code which gives me the size of the volume if i feed it the drive letter of that volume. am make use of the interrupt 21 function 360 approach elsewhere in my code to get the free space on a volume,
but the int 21 function 360 approach doesn't return values higher than 2Gb as free space it is not making an issuefor the code that i use
but create for the new bit of code, i want the volume size returned precisely for fat16 and fat32 drives for any size

thanks for reading me...

I appreciate for your work..i think i would rather shell to a 32-bit Windows program it allows to grab those oversize values, passing the drive letter on the command line and returning the size as a display integer
try this format ("FORMAT$(value)" in PB/Win-speak).

good luck

I have got some old code for you does not know is it work out or not may be you just try..Type DiskInfo
InfoLevel As Word
SerialNum As Dword
VolLabel As String*11
SysType As String*8
End Type

Dim MyDisk As DiskInfo

MyDisk.InfoLevel = 0000 'just has to be 0.
MyDisk.SerialNum =
VolLabel = "A vol label" 'sets volume label. fill with
'"NO NAME " for no name.
'First get SysType, then use it to set.

!PUSH DS
!MOV AH, &h69 ;function number
!MOV AL, &h00 ;00=Get number, 01=set number
!MOV BL, &h00 ;00=default drive. 1=A, 2=B, 3=C, etc.)
!MOV BH, &h00 ;this has to be 0.
!MOV DX, VARPTR(MyDisk)
!MOV DS, VARSEG(MyDisk)
!INT &h21 ;call DOS
!POP DS
