which api to obtain drive name

[azdps]

i need to obtain the drive name. the same name that is displayed in device manager when you view the devices listed. i'm able to obtain the drive volume just fine.

[evlncrn8]

think you need to use IOCTL_STORAGE_QUERY_PROPERTY on the drive
google for it, and the structs should be there (msdn).. the vendorid, revision etc
is what you're after, if NULL, there isn't an entry, if there is an entry its
the start of the struct + the dword from the entry = the data you want...

note: you might need some access rights / privileges to get this information,
in most cases all you need is GENERIC_READ access to the drives...

in the cases of cd/dvd drives, for scsi based units, the vendor id is not present..

either way, do some experiments, but that info should set you on the right track

You could then do something like the following, i use an array of a structure to store all relevant info into:

Code Select Expand


LOCAL DevDesc[512]:byte ; DeviceIO DevDesc information
LOCAL nProductVendorSplit:DWORD

Invoke OpenDrive, Addr szDriveRoot ; open the drive
.IF eax != INVALID_HANDLE_VALUE
mov hDrive, eax
Invoke GetDriveInformation, hDrive, Addr DevDesc ; get deviceio information into our structure


; Get vendor and product id offsets
; if product id > 0 and vendor id = 0 then IDE type and need to parse vendor from product string bug
mov eax,[DevDesc.STORAGE_DEVICE_DESCRIPTOR.VendorIdOffset]
mov ebx,[DevDesc.STORAGE_DEVICE_DESCRIPTOR.ProductIdOffset]

.if eax == 0 && ebx > 0 ; bug, so parse out

mov nProductVendorSplit, 0
mov eax,[DevDesc.STORAGE_DEVICE_DESCRIPTOR.ProductIdOffset]
xor ecx, ecx
lea edx, DevDesc
add edx, eax


VendorProductSplit:

xor eax, eax
mov al, byte ptr [edx]

.if eax == 20h || eax == 0 ; stop here
inc ecx
mov nProductVendorSplit, ecx

.else
inc ecx
inc edx
jmp VendorProductSplit
.endif 

mov esi, dwDriveMatrixArrayOffset ; array to store drive info to
lea ebx, [esi].DRIVE_MATRIX_RECORD.szDriveVendorName ; i use a structure to store info in here
mov eax,[DevDesc.STORAGE_DEVICE_DESCRIPTOR.ProductIdOffset]
lea edx, DevDesc
add edx, eax
Invoke lstrcpyn, ebx, edx, nProductVendorSplit


mov esi, dwDriveMatrixArrayOffset ; this is my array to store drive info to
lea ebx, [esi].DRIVE_MATRIX_RECORD.szDriveDeviceName ; store devicename in my user defined structure
mov eax,[DevDesc.STORAGE_DEVICE_DESCRIPTOR.ProductIdOffset]
lea edx, DevDesc
add edx, eax
add edx, nProductVendorSplit
Invoke lstrcpy, ebx, edx
.else

; Save Vender Name
mov esi, dwDriveMatrixArrayOffset
lea ebx, [esi].DRIVE_MATRIX_RECORD.szDriveVendorName
mov eax,[DevDesc.STORAGE_DEVICE_DESCRIPTOR.VendorIdOffset]
lea edx, DevDesc
add edx, eax
Invoke lstrcpy, ebx, edx

; Save Device Name
mov esi, dwDriveMatrixArrayOffset
lea ebx, [esi].DRIVE_MATRIX_RECORD.szDriveDeviceName
mov eax,[DevDesc.STORAGE_DEVICE_DESCRIPTOR.ProductIdOffset]
lea edx, DevDesc
add edx, eax
Invoke lstrcpy, ebx, edx

.endif

This is my structure i use, which i fill by calling Invoke BuildDriveMatrix, Addr DriveMatrixArray, part of which is shown above, i define it as DriveMatrixArray DRIVE_MATRIX_RECORD 26 dup (<>) and just pass the builddrivematrix function the addr of the array, so it will fill in all the info i am looking for:

Also here is the structures and data for deviceio stuff:

Hope that helps give you a few pointers.

[azdps]

excellent examples fearless. i'm having a problem with IOCTL_STORAGE_QUERY_PROPERTY though. when i assemble i get the following error: undefined symbol : IOCTL_STORAGE_QUERY_PROPERTY

[azdps]

I looked at WinIoCtl.h file and saw that its defined but i'm having a hard time defining it in .asm file. i have it as:

IOCTL_STORAGE_QUERY_PROPERTY equ CTL_CODE(IOCTL_STORAGE_BASE, 0x0500, METHOD_BUFFERED, FILE_ANY_ACCESS)

but its not working. how do you properly define it?

[fearless]

Im in work at the mo, but ill have a look when i get home and check for you. Probably after 7.30ish my local time.

[ToutEnMasm]

Seems you have the header.h

Have a look here http://www.masm32.com/board/index.php?topic=10661.msg78096#msg78096

and all will be translate

[fearless]

I have this defined in my file, most from header files and some from google searching on particular structure or deviceio constants and possibly other sources.

[dedndave]

either WinIOCtl.h isn't getting pulled in or the equate isn't (is it defined in a macro ?)

MS docs say it is here.....

        Include Ntddstor.h

[PBrennick]

I get the ioctl values from Donkey's constants.inc (WinExplorer.exe, etc.)

You can just add the equate to your source though in the following manner;

IOCTL_STORAGE_QUERY_PROPERTY equ 02D1400h

[azdps]

thanks its all working now. wonder if hutch plans on adding those to the masm32 includes.

[PBrennick]

Why not ask him to? He generally adds what people seem to need so as to keep the size of the file as small as possible.  :thumbu

Hey Drizz,

I forgot all about the four-f stuff. Very useful for certain things.
Donkey is pretty darn thorough, though, and his stuff works for me.

Donkey has move to GoASM...

anybody post the WinExplorer Source (Masm32 Version)?
