Problem with transferring library to new drive

[leio]

Hi, so I just got a new external hard drive and I managed to successfully move some of my Calibre libraries to it without any issues. However when I try moving one of them (my largest one, it's nearly 30g) I *immediately* get an error, and my external drive becomes corrupted. I plug it out, plug it back in, windows tells me it has a problem, it scans the drive, finds no problems to fix and it works normally again. Some help would be greatly appreciated...

calibre, version 5.22.1
ERROR: Failed to move library: There was an error while moving the library. The operation has been aborted. Click "Show details" for details.

Traceback (most recent call last):
File "calibre\utils\filenames.py", line 593, in copytree_using_links
TypeError: 'NoneType' object is not callable

During handling of the above exception, another exception occurred:

Try this:

• Remove the library from calibre via the Remove library action, don't worry it won't delete the library folder or anything in it.
• Copy the library folder manually to the new drive
• Add library on the new drive to calibre via the Switch/create->Use the previously existing library at the new location option
• If all is OK delete the library on the old drive, use Shift+Del to avoid filling up the Recycle Bin

Wouldn't this delete the tags and other such info on the books though? I'd really like to keep those... is there a way to?

No it wont, all it does is to 'unhook' the library from calibre. The tags etc are in the library database file (metadata.db) which is in the library folder.

Is there any advantage to using calibre to transfer a library to another drive? I've always just copied the calibre library directory and then pointed calibre at the new directory.

Slight!
The tool also grabs the configuration folder.
The tools will/can do all KNOWN (to Calibre) Libraries

Damn I swore that happened to me once... must've misremembered then. I'll try that, thank you!

No dice, it transferred about 2GB but won't let me transfer any more than that. I get the same "A device which does not exist was specified." and related errors then when trying to transfer through the app

That sounds like it's dropped a USB connection or something. If you're physically transferring it outside of Calibre and you're getting an error like that, there's a probably a hardware problem.

I think the OP was using the Move current library to new location option in the Library Switch/create tool. And I suspect you're thinking of Export/Import.

yup! to me, that is how to move to a new computer.
I wonder about the new drive file system type. Or if the OP is putting the Library folder as the root of the drive?

So... I guess this either was a hardware issue from the start or it eventually turned into one. At this point my drive has become completely innaccessible so nevermind I guess. Sorry all and thanks for trying to help anyways lol
