Good points about rebooting on the Mac, and removing the USB devices on Windows and allowing it to recreate them. I have been lucky and my Sony Reader has always been very reliable, but I have noticed that some other USB2 devices like Thumb drives and external USB hard disks can be fussy about working on some PCs depending on which USB2 port I plug them into. I would try another cable and another USB port on your PC, and if that doesn't work, check your reader on another completely separate PC.
Of course, if you are not using any external plug-in memory, those drives are not readable, but your readers internal memory should ALWAYS be there, already formated and ready.

As soon as the PC does the proper handshaking, your reader should pop up on the desktop as several different USB drives - One for the readers internal memory, one for the SD card slot, one for the Memory Stick slot, etc. When connected to a PC, these data pins are never shorted, but instead should always have valid data signals on them, and your Sony reader should detect this and go into 'USB Storage Device Mode' instead. Ī PC USB port should NEVER look like an external charger, unless the USB cable or port on your PC is defective and shorted, because external chargers have the two USB signal pins associated with data transfer shorted together (that's how the Sony knows it's connected to a charger instead of a PC), but a PC port should never show up this way.
The symptoms you are describing are truly strange. Did a hard reset, still "not recognized." When I plug it into the computer, the battery icon (on the reader) turns all black and a little arrow icon appears to the right of the battery icon in the bottom bar, and the red light is on at the top of the reader- seems like it thinks it is connected to an external charger? I've never used an external charger before, but I've read that you can continue to use the reader while it is charging, and that would be an explanation for the little arrow by the battery.Īny ideas? Could there be a problem with the cable, or a physical problem in the reader? Since it formatted itself, I'm stuck with no books on the reader and no way to get them back on. Did a soft reset, still the "not recognized" message. I try rebooting the computer to see if it can recognize it (after it formatted itself), no luck. Unplugged it and it gave the "exceptional internal memory state formatting" message- which gives no chance of canceling, there's only a "yes" button. I plugged it into the computer tonight (it had 3 bars on the battery at the time) and up popped the message "USB device not recognized." Windows Explorer didn't show it as a pair of removable drives, and Calibre didn't find it.
