Re: [python-win32] Does pywin32 support SD card operation(IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL)?

How can I know if my SD drive support the ioctl? I tested IOCTL_SFFDISK_DEVICE_COMMAND and it worked (did not get any errors.) However, IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL is not working. If IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL is not supported, do you know other ways to tell if the device is SD

Sorry! I forgot to change the subject in the previous email. Thank you for your help! No luck so far. I wrote a C program and got the same results as python: Win 7 Notebook (with SD card inserted directly i.e. no SD card reader) Error code: 1 Win 7 Notebook (without SD card inserted at all) Err

I want my script to tell if the removable disk is an SD card or not, so I wrote the following script. buf_fmt='HH'   buf_size=struct.calcsize(buf_fmt) drives = (drive for drive in win32api.GetLogicalDriveStrings ().split ("\\\000") if drive)         for drive in drives:             if win32

Re: [python-win32] Does pywin32 support SD card operation(IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL)?

That one isn't in winioctlcon.py yet, but you should be able to define it relatively easily. According to the headers: #define IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL \ CTL_CODE( FILE_DEVICE_DISK, 0x7a0, METHOD_BUFFERED, FILE_ANY_ACCESS) You'll probably need to create the output buffer

[python-win32] Does pywin32 support SD card operation (IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL)?

Hi All, Does pywin32 support SD card operation (IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL)?   I google IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL with Python. However, no useful information shows up.  My code: if win32file.DeviceIoControl(hVol, winioctlcon.IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL, 0, 6, 0): Er
