Interesting. I went to Sony's site to see if there were any updates for my PDA. Sure enough, there is an update. I download it, install it per the directions, and try out the new software, which was an update to the camera software.
Well, the updated software not only does not work with my PDA, it also makes the memory stick start choking when it is trying to play MP3 files, giving me an error stating that the MP3 is improperly encoded, that my memorystick is not available, and something else that I have since forgotten, since I was frankly pretty pissed off at the moment in time. Also, it is no longer recognizing the card that I have in the device.
OK, yank that card, drop in my other one. Nothing. While the small LED does blink to show that the PDA is trying to read the card, it is not recognized, and I can read no data off the card. Okay, maybe my cards are both fried, maybe I somehow bent them in the case that I made, rendering them inoperable. I check both cards in my PC, and have no trouble reading, writing, adding or deleting anything from them.
I reset the PDA, a process not unlike pithing a frog, as it involves inserting a small pin into the back of the device, to get it to restart. OK, now it will recognize the cards that I am inserting, buy about three tracks in I start getting the same error message again. Bah.
Pith it, restart, and after a few tries it no longer recognizes the stick at all, no matter how many resets I attempt. I am starting daggers at the device at this point, trying to figure out how/why it has decided to betray me. I run through the list of apps that I have recently installed that may have caused this to happen. Only one comes to mind, as it is the only one that I have installed in the past week. Fine. I delete the app, reset, and still the PDA refuses to notice the Memory stick. I set it aside for the night, and retire.
The next day, I get up, and reluctantly insert a stick in the hopes that it will be recognized. It is. I look at the device with one eye, not entirely trusting that which I am seeing. I open up the audio player, and start listening to tracks as I begin to write this very screed. Sure enough, it gets up to track 9 (so far) without a hitch.
The moral of this story: seemingly unrelated and innocent updates may well hamper the use of your gear.
