Hm. Only PIE scanned in PX-716A? My result with MCC004 at 16x showed less than 100 total PIF errors when scanning in SOHW-1613S BS41 firmware at 2x read speed and about 125 at 4x read speed. It's probably just a matter of time to see 4.7GB completed in less than 5:20 and still shows less than 5,000 PIE's and 10 PIF's.
Anyway, now A101 firmware is out finally.
(All my GSA-5163D tests were done with A101 firmware.)
