WES 7 Driver Help Needed

NTDEV
1

I have a driver developed for Windows 7 that makes a small 1MB RAM device on our board appear as a Windows drive. Works fine.

Tried the same driver on Windows Embeeded Standard (WES) 7 and the drive appears but Windows says that it needs to be formatted. The format I am using is FAT12.

Anybody know why WES7 does not like FAT12? Also, the KdPrint statements do not display on my WinDbg console. Does WES7 require something to be configured for debug?

Thanks in advance.

Does it work on “regular” Windows 7?

I would GUESS that Fat12 *should* work… though it’s an odd choice for something that’s not a floppy.

Have you considered changing-up the format to FAT16 at least, see if that makes a difference?

Works fine on regular Windows 7.

Did try the FAT16 on Friday with no luck.

Really have no other clues as to why the driver likes regular 7 but not WES7. I have verifies that the contents of the drive on each O/S are the same.

Just a hint : if you are using FILE_DEVICE_VIRTUAL_DISK when you create your device , try FILE_DEVICE_DISK instead.

Is FastFat driver included to the OS installation?
