Sony PRS-T1 (Failed to Access Files)

[vOceanic]

Hello, all!

I promise I Googled / read a bunch of threads / tried a bunch of steps before resorting to a post, haha.

I've been using my Sony PRS-T1 for 1.5 years with Calibre on Windows 11. Some slight weirdness with set-up and transfer, but nothing too bad or remarkable.

As of today, I'm getting this error, which stops me from transferring books to the device:

calibre, version 6.7.0
ERROR: Error: Error communicating with device

Failed to access files in the main memory of your device. You should contact the device manufacturer for support. Common fixes are: try a different USB cable/USB port on your computer. If you device has a "Reset to factory defaults" type of setting somewhere, use it. Underlying error: [Errno 22] Invalid argument: 'D:\\driveinfo.calibre'

Traceback (most recent call last):

File "calibre\devices\usbms\driver.py", line 139, in _update_driveinfo_file
OSError: [Errno 22] Invalid argument: 'D:\\driveinfo.calibre'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

- I downgraded from 6.7.1 to 6.7.0, and the error persists
- I tried a few different USB ports
- I rebooted the computer and the device each several times
- I deleted driveinfo.calibre and metadata.calibre (it seems as if metadata has not reappeared...)
- I deleted some of the files on the main drive. (There aren't many, so I don't think it's a volume issue).

Any idea? (Is it Windows 11 sucking? LOL)

The PRS-T1 was an eBay snag just to see if I would actually use an eReader. I've been really enjoying it (and Calibre) for the past year, and would hate to give it up.

That said, I also don't know if re-formatting will solve the issue. I will if I have to, but am hoping to avoid that if possible.

Any advice is welcome! Thank you to everyone on the forum

You can upgrade back to 6.7.1. That's not the problem.

Plug in the T1 to the USB and try running a chkdsk on it and see what happens.

The problem could be that the T1 is failing. It is 11 years old. If it is the case that it's failing, I suggest you go for a Kobo Libra 2 as a replacement. I was using a T1 when I switched to Kobo.

its an error reading a file from the device. A reformat/reset is your remaining option.

Thank you both! I will try both of those and get back to you. I appreciate it a lot.

ETA: Formatted / eraesd the drive via Quick Format through Windows Explorer. Works like a charm again. Interesting!

Thanks to both of you again; take care.
