Firmware Update Problem

[LynneE]

Wanted to update my DVD burner because it was running SOOO SLOW in DVDFab. It identifies as ATAPI iHAS124 F
So far so good.
Two firmware files are available CL99.exe and CL09.exe
However BOTH FAIL !!
Message reads:
No matched drive detected!
This utility is only for ATAPI iHAS124 F drive

Detected drives:
0-3-0-0 E:ATAPI iHAS124 F CL9E

Highly confused - help appreciated

Howdy! Ever figured out which firmware worked?
