Как-то так можно:

BOOL result = TRUE;
wchar_t volumeName[MAX_PATH] = {0};
wchar_t foundVolume[MAX_PATH] = {0};
HANDLE hFind = INVALID_HANDLE_VALUE;
HANDLE hDev = INVALID_HANDLE_VALUE;
// Iterate volumes
for(HANDLE hFind = FindFirstVolumeW(volumeName, sizeof(volumeName) / sizeof(wchar_t));
hFind != INVALID_HANDLE_VALUE && result != FALSE;
result = FindNextVolumeW(hFind, volumeName, sizeof(volumeName) / sizeof(wchar_t)))
{
wchar_t volumePath[MAX_PATH] = {0};
DWORD retLength = 0;
// Get mount points for volume
if(GetVolumePathNamesForVolumeNameW(volumeName, volumePath, sizeof(volumePath) / sizeof(wchar_t), &retLength) == TRUE)
{
UINT dType = GetDriveTypeW(volumeName);
// Save first volume without mount points located on removable drive
if(dType == DRIVE_REMOVABLE && volumePath[0] == 0)
{
wcscpy(foundVolume, volumeName);
// Remove trailing slash
if(foundVolume[wcslen(foundVolume) - 1] == L'\\')
foundVolume[wcslen(foundVolume) - 1] = 0;
break;
}
}
}
if(hFind != INVALID_HANDLE_VALUE)
FindVolumeClose(hFind);
// Open volume for read/write
hDev = CreateFileW(foundVolume, FILE_READ_DATA | FILE_WRITE_DATA,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
if(hDev != INVALID_HANDLE_VALUE)
{
BYTE buffer[512] = {0};
DWORD bytes = 0;
// Read data

// Write data
