Export fail

dchapman · 05-19-2024, 12:25 PM

Good day.
I hope this is the correct forum.

I had an export fail and return this error:

---------
calibre, version 7.10.0
ERROR: Failed: Failed to export data. Click "Show details" for more information.

Traceback (most recent call last):
File "calibre\gui2\dialogs\exim.py", line 156, in run_action
File "calibre\utils\exim.py", line 212, in export
File "calibre\db\cache.py", line 85, in call_func_with_lock
File "calibre\db\cache.py", line 3164, in export_library
File "calibre\db\cache.py", line 1225, in copy_format_to
File "calibre\db\backend.py", line 1823, in copy_format_to
File "shutil.py", line 197, in copyfileobj
OSError: [Errno 22] Invalid argument

---------
I have no idea what this means or if I have to do something befpore I try another export.

Thanks.

Are you exporting to some non-standard filesystem?

C:\Users\dchap>ver

Microsoft Windows [Version 10.0.22631.3593]

C:\Users\dchap>

The libraries and the destination directory are on separate USB drives.

The question is what is the FILESYSTEM on each of those drives.
You can use Windows Disk Management to discover the partition being used

FAT32, NTFS, exFAT are filesystems

Ver just gives the version of Windows.

** BLUSH **
I thought of that about 10 minutes after I posted.

The drives are WD External USB drives both NTFS.

Thanks.

That should be fine. Try rebooting in safe mode and see if the error still happens.

dchapman · 05-20-2024, 07:41 PM

Thanks for the response. I have yet to successfully get this machine into safe mode - at least not with networking. I used msconfig.

I tried another complete export and after about 20 hours it finished successfully.

Perhaps my issue was a one -ff.

Thanks again,

Do the two drives share a USB hub or a disk dock?

I have two WD black caviars in a two-slot USB 3.1 dock, copying between them is substantially slower that copying to/from an internal SATA III 6Gb/s.

A pair of Seagate USB 3.0 HDD backup drives (1T but different models) were also about 1/4 speed of an ex-laptop 5400 rpm SATA in a 3rd party USB 3.0 SATA adaptor case.

A 6T 3.5″ desktop 7200 rpm SATA in a big USB 3.0 adaptor case is fastest backup by far. Nearly as fast as internal drives.

All tested on real USB 3.0 ports with USB 3.0 cables. The "A" connector is coloured blue and has 5 extra connections (at back on plug and at front on socket).

Most laptop 1T or larger SATA drives also seem to be very much slower than the best WD Black 512G laptop 5400 rpm drives.

Thanks, everyone.
The drives are slow, for sure. But I have more time than money.
The computer's USB-C port plugs into a dock, and then to a 10 port powered USB hub that has 8 hard drives, a CF reader and a XQD card reader. Yes, it is slow. :-)
