Hi,

You can use the following APIs to get the currently available disk
drives on your machine:

GetLogicalDrives()

GetLogicalDriveStrings()

GetDriveType()

You should tell a bit more specifically what type of information you want.
SCSI ID's?
Anyway, FindFirstVolume() might give you something useful. Or maybe even
FindFirstVolumeMountPoint().
And ofcourse one knows that the physical devices are accessible
(CreateFile()) using paths such as \\.\PHYSICALDRIVE0
Then there is DeviceIoControl with FSCTL_GET_NTFS_VOLUME_DATA and/or
IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

And of course there are PnP related API's but i think they are more
appropriate in kernel mode. But try EnumDeviceDrivers and

If on the other hand you want logical drives, check out GetLogicalDrives().

Hi,

You can use the following WMI class to get the name of the disk
drive manufacturer:

Win32_DiskDrive

Simply enumerate \Device\HarddiskX?

[Alex]

Hi,
i have enumerated "PhysicalDriveX" in CreateFile
then i have tested returned value

but i would find a kind of function which gives
number of physical hard drives or handles to physical drive

Hi
i have a linker when using SetupDi functions
(i work under vs2008) can u help me?
which library contains this functions? :)

WMI: Win32_DiskDrive - just call WMI from C++ - it's just COM API.

Always avoid WMI and use the method mentioned above.
It is slow and not installed natively on OS like NT.

Microsoft says we shouldn't care about NT4- and Win9x/ME any more, but
rather base everything on the Win32 API as in NT5.

Customers decide, not Microsoft.
Many are running NT4.
