Mini Tape Driver And Writefile?

NTDEV
1

I need a way to debug writefile on a end user system. Writefile doesn’t appear to be handled by the minitape driver but I want to verify that eot (end of tape) is being detected by writefile. I see it on a SCSI trace but the application people are saying that writefile is not returning this error status. Also is writefile handled by the tape class driver?

Any assistance would greatly appreciated.

Thanks!

In yor miniclass driver, you can initialize the following routine:

TAPE_STATUS
TapeMiniPreProcessReadWrite(
IN OUT PVOID MinitapeExtension OPTIONAL,
IN OUT PVOID CommandExtension,
IN OUT PVOID CommandParameters,
IN OUT PSCSI_REQUEST_BLOCK Srb,
IN ULONG CallNumber,
IN TAPE_STATUS StatusOfLastCommand,
IN OUT PULONG RetryFlags
);

This routine will be called before each SCSI read ad write operation to the
tape device; it is like a filter so that you can preprocess reads and wrotes
for your specific device.
