I noticed you are BRAND NEW here and Your FIRST POST is about something
very few people (if that) are experiencing. Just as others thought the reader
was "massively slowing down" which turned out to be a bad memory card
or corrupted files, I suggest your own individual hardware setup or some software
might be the cause of your ISSUES/PROBLEMS.
Out of the box, my reader and sony software ran without incident or hitch
and I'm using a brute force firewall with self learning TCP traffic filters turned ON!
I suggest you call sony support or bring it to a sony service center.
Hopefully when you figure out what the culpret is on your system/software
you will enjoy your reader like many others...
good luck to you.
p.s. DO NOT SUBSTITUTE THE OEM USB CABLE that sony provides.
