This is odd. It was working last week. But this morning calibre will not recognise my 505.

I've upgraded to the lastest version. Windows is happily recognising the 505 will let me browse etc etc.

The Sony software has never been installed on this machine.

Run


prs500 info
prs500 df


in a terminal with your reader connected and post the output

As requested:

calibre>prs500 info
Unable to detect the PRS505 disk drive. Try rebooting.

calibre>prs500 df
Unable to detect the PRS505 disk drive. Try rebooting.

I should mention that it's already been rebooted at least once since this started this morning.

OK now try the following


calibre-debug -c "from calibre.devices.scanner import DeviceScanner; s = DeviceScanner(); s.scan(); print s.devices"


calibre-debug -c "from calibre.devices.scanner import DeviceScanner; from calibre.devices.prs505.driver import PRS505; s = DeviceScanner(); s.scan(); print s.is_device_connected(PRS505);"

calibre>calibre-debug -c "from calibre.devices.scanner import DeviceScanner; s = DeviceScanner(); s.scan(); print s.devices"

calibre>calibre-debug -c "from calibre.devices.scanner import DeviceScanner; from calibre.devices.prs505.driver import PRS505; s = DeviceScanner(); s.scan(); print s.is_device_connected(PRS505);"
True

As requested.

OK next debug


calibre-debug -c "from calibre.devices.prs505.driver import PRS505; d=PRS505(); d.open(); print d.total_space()"

here you go:

calibre>calibre-debug -c "from calibre.devices.prs505.driver import PRS505; d=PRS505(); d.open(); print d.total_space()"

Looks like the deviceID on your system has changed, post the output of


calibre-debug -c "import wmi; print [(str(drive.PNPDeviceID), drive.Partitions) for drive in wmi.WMI().Win32_DiskDrive()]"

Interesting, wonder why the heck it's done that.

Nope ids are fine, the problem is that for some reason windows is reporting that the main memory in your device has no disk partitions and is therefore not mapped to a drive letter.

Only thing I can think of that's causing this is some aggressive antivirus software.

I have Spohos installed.

But its been insalled longer than calibre :-)

Something on your system must have changed to cause this, any recent updates?

Another thing to try is reformatting your reader internal memory (you will lose any books on it).

Beyond normal security updates, none that I know of.

I'll attempt a format when I've finished my current book.

Nope still won't recognise it (really wish I had thought to transfer off the zip file I had of books on there before I did it).

Hmm nothing comes to mind I'm afraid. calibre relies on windows informing it correctly of the presence of the main memory in the device.

had same error problem

505 and latest version of calibre

unplugged a couple of times and rebooted calibre and fingers crossed managed to upload a couple of books

no idea what the issue was???

Was able to upload books happily via another machine and calibre. It just appears to be this machine thats having issues.

I have tried removing calibre entirely and installing from scratch, and that didn't work. It just seems very odd.

Hi there! - I currently have the same problem - have been running Calibre on my Windows XP laptop successfully for some months - of a sudden, a couple of weeks ago, Calibre doesn't see my 505 or the card. I tried installing the Sony software and that saw the device and the card, Windows Explorer sees the card. I've re-installed Calibre and I've reset my reader - no effect. Calibre will save book files to the card via the 'save to disc' option. I'm not a techy person and I've run out of options now. Any quick and easy, sure-fire solutions welcomed!

With your reader connected, open a terminal and run


calibre-debug -d


and post the output

Well that was an adventure for a non-tech chap! Anyway, here's the output:

- I hope it makes sense, thank you for your time. I think this is something to do with the reader and not Calibre - my other machine running Vista Ultimate 64bit and Calibre 1.135 - can't see the device in Calibre although Windows explorer sees it and allows file copy to the device etc. It started when I tried to put in a Sony 8Gb memory stick along with a 4Gb SD - I could only ever get to see the Sony stick. I did a rather rash reader reset - but no change. After that there was a period when Calibre could only see the device and no card, and then later neither.

Looks liek a problem with the card. I suggest reformatting your card. In windows right click on the F: drive and select Format. This will delete everything on your card so copy anything on it to your hard disk first.

Super! I'll try that tommorrow and let you know what happens. Ta

What a star! it works now! When I removed the Sony Stick Calibre was able to see the reader. I reformatted the card using Windows as a FAT32, inserted it, turned the reader on and off a few times until it detected the card and, hey Presto!, there it was as good as new. Anyway, I've uploaded my library through Calibre again and it's all OK. I do like happy endings!

Thanks very much - very grateful for the help
