Reading a floppy serial number... 1

[Elliott3]

Hi,
Can someone tell me how to read the serial number of a floppy disk?

Hi Elliot,

This uses MFC but you can adjust it for your needs

[tt]CString serial;
char vol_name[128];
DWORD serialNum = 0x0;
DWORD data = MAX_PATH*sizeof(TCHAR);

if(GetVolumeInformation("A:\\",vol_name,sizeof(vol_name),
&serialNum,&data,NULL,NULL,NULL))
{
serial.Format("%x", serialNum);
}[/tt]

Hi qednick,
Thanks for the info.
Do you know why 6 out of 9 disks I tried returned zero (0)?

All floppy disks do have a serial number....don't they?

Well I always thought so - I'll give it a try and see what happens.

I tried it with several floppy disks and they all successfully returned the volume name and serial. I don't have any unformatted disks to hand to see what happens in that case.
Were all your disks formatted and labelled? Perhaps the ones that didn't work were formatted but not labelled or something like that? Other than that nothing obvious springs to mind.

Thanks qednick.
None of my disks were labelled, so I labeled one to see if it would change anything but no luck, the serial number is still zero. Anyhow, I will just have to label the disks and get the label with the method you have suggested.
Thanks again for your help.

No probs Elliot, floppy disks are not the most reliable of media at the best of times. Perhaps a different brand will help.
