Storage Identification

I'm not sure what storage ID corresponds to in WinCE. You might try IOCTL_STORAGE_GET_MEDIA_SERIAL_NUMBER, but I don't know how well it would correspond to what wince returns.

The number you're getting is very likely stored on the sectors on the device, just not in ones that are normally accessible to READ and WRITE commands.

That's my question !

I found it to be a good way to get a unique identifier for the memory card...
It consists of a string made of decimal numbers (such as "758841430") and can be obtained using IOCTL_DISK_GET_STORAGEID on WinCE...
I guess the driver is the one to provide this number... but don't know the logic.

I've read it is a mix between the manufacturer name and the size/characteristics of the card.
But it is not the case... identical cards (same size, ...) from the same manufacturer returns different numbers.

And I just found out that the card name is also stored somewhere by the driver but not on the sectors available at low level...
In the MBR the drive name is still "NO NAME".
