Tape drive access with Createfile

I can gain access to a tape drive with createfile - then can load, unload, position tape, rewind - all work fine - everything except Read. I have tried both BackUpRead and ReadFile with no success - also tried the standard example by Ethan from this forum - same problem.
( I can read the tape via ASPI- but its way too slow )

Does anyone have ideas ?

Thanks

ps OS is Win 2K SP5, language is VB6

Do you get any error(s) when trying to read using ReadFile?

Make sure you specify the last parameter as ByVal 0& if you didn't use FILE_FLAG_OVERLAPPED in CreateFile...

Post your code...

Hi Darko

Thanks for your reply.  The byVal did it !
Now I can read from my Exabyte ( TAPE0 )
I have been staring at this thing for 2 days ....

Case closed - the points are yours.
Thanks again
