This is really wierd. I had an Ativa DH-20A3H with a date of December 2008.
The busy lite is on the right side of the drive like it is supposed to be.
I got another drive, January 2009 firmware QA71. This drive is supposed to be a DH-20A3H.
It is not, it is a DH-20A4H. If you dump the firmware and load it thru CK's flasher it shows 'S' firmware. Hmmmmmm.
The drive will not take any firmware for the A3H drive, but will take firmware for the A4H drive...
Is this a rip off or what.
With the stock firmware installed , the drive shows up as a 20A3H....(QA71).
I dont think they made a 20A3H after 2008?
