Thanks for the update. I expect new firmwares for 5200A, 7200A/S, 7201A/S and 7203S soon. According to the changelog, read speed for Video DVD has been reduced from 12x to 8x

What is the advantage of this reduction of speed?

The likely answer is a reduction in noise when the drive is used for playing video.

In change log of AD-7203S, don't report reduction of speed.

But it's mentioned in the AD-7203A firmware 1.07 changelog.

AD-7203S is stationary at 1.06, maybe it's only a problem for EIDE?

Really looks like an AD7200A OEM firmware.

Probably caused by newer files containing 2 firmwares in 1 flasher. It looks like they changed the drives' bootcode and have supply one firmware for each bootcode.

Already thinking of how I can best implement this in Binflash.

scan from my older drive, No differences other than serial and date, unlike plextors with their tla number (TLA # 0202 -> hardware revision 02 original Fw 02)

liggy should I open the newer one and scan the interior for you??

If you dump your drive's firmware, Binflash adds the bootcode version as the last two bytes of the firmware file.

in that case, the same bootcode for both drives. I thought it was the checksum place. No checksum like with liteon drives ???, i've fooled around in those (832S)?? too risky i guess to do so with nec. no "repair" mode (afaik),or j-tag??

on the other hand. i've just compaired 1.06 original from your site with my dumped 1.06 (original in the drive) and they are a bit different in the last byte
and also in the firmware there are differences

not that my new drive malfunctions, everything seams to be ok


from my older drive with original fw 1.01 the dump is an exact match with 1.01 on your site
