Question Sony PRS-900 error message

I've been running calibre with my Sony since Oct '10 with no problems. Today I decided to transfer my books off my SD card and into the Sony's internal memory. I plug the reader into my comp and fire up calibre. Sony is detected, but then I get the following error message:

[Errno 22] invalid mode ('wb') or filename: u'J:\\metadata.calibre'

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 64, in run
File "site-packages\calibre\gui2\device.py", line 315, in _books
File "site-packages\calibre\devices\prs505\driver.py", line 146, in books
File "site-packages\calibre\devices\usbms\driver.py", line 160, in books

File "site-packages\calibre\devices\usbms\driver.py", line 303, in write_prefix
IOError: [Errno 22] invalid mode ('wb') or filename: u'J:\\metadata.calibre'

J: is the 16GB SD card in the Sony. This error occurred before I updated calibre, so I updated. Same error message. I then followed the steps in your "Device" sticky to see if that would help. Sony plugin is green and the info from the debug is:

That error message suggests that Calibre is unable to get write access to the J:\metadata.calibre file. This could be because there is a problem with the SD card - it might be worth doing a CHKDSK on it in case there is some format/corruption error at the file system level.

You could probably also simply remove that file and let calibre recreate it if required as another way around the problem.

I removed the metadata.calibre file, but it kept reappearing as the same file with 0kb. I finally thought to rename it to metadatas.calibre. That worked. A new file was generated and is on the SD card with original name, but 110kb. Thanks!

BTW, what does the "wb" mean for an invalid mode?

This suggest that there was a problem with the file system on the J: drive. If you go into a DOS Command Window and run
CHKDSK /F J:
this should fix any errors.
Alternatively you could do this via the Properties of the drive and the option on the Tools tab.

Ran the CHKDSK and found a small problem. Fixed and formatted. Damn card is only a couple months in use! Thanks for the heads-up, itimpi!

You can always get small issues if you remove the device without doing a clean eject.
