I just got this answer from mydisk.se support service. If you are having similar error, I encourage you to disable webdav synchronization until either zotero or mydisk.se can fix the problem.

We have had performance issues which seem to be related to the use of Zotero by some of our users. It seems like you are using an application which is trying to access files that don't exist on your account which is causing heavy traffic on mydisk.

Here is one example from your account:
[Mon Mar 02 12:30:27 2009] [error] [client 190.50.45.32] File does not exist: /var/www/amastronardi/zotero/TTK29JXS.prop

We have made a temporary fix to protect our servers by locking webdav for the users creating this errors and you were one of them. We are working on identifying the cause of these issues...

I'm also using mydisk as the WebDav and yes, I have lots of attachments with missing files. I'm getting errors similar to the ones above. Hopefully mydisk finds a solution to this soon.

I have been trying to sync with mydisk.se. 'File storage is successfully set up' according to Zotero, but there seems to be 3 files that make the sync hang. I don't know what these are, I can only tell by hovering over the progress bar. Any ideas?

Thanks.

Dear Zotero users

We got many users from Zotero lately which is causing an excessive amount of errors on our servers, as mentioned by amastronardi, above.

For this reason, we have decided lock MyDisk for users trying to connect with Zotero. Please send us an e-mail if you would like us to unlock your account in order to use MyDisk for what it is primarily meant to, such as easy file access, webpage publishing or displaying your photos.

We are sorry for the inconvenience and hope that you still appreciate MyDisk for the service we are primarily supporting.

Best regards
MyDisk.se

Bummer. Like CB, its back to DropBox for me as well.

As an afterthought, if I can no longer access mydisk for Zotero file attachment sync, do I need to manually move all of the files out of mydisk or are the attachments also stored in my local Zotero storage folder?

Cheers.

Sigh. I'm biting the bullet as well and trying out JungleDisk. Where do I find the URL for file sync?

There are two possibilities. If you're running the jungledisk client all the time, it provides a local URL. I think that's http://localhost:2667, but I couldn't get it to work with zotero.

I don't want to run the jungledisk client all the time anyway, so I'm using their WebDAV server, for which the url is https://www.myjungledisk.com/[your jungledisk online disk name] (username/password details as per your jungledisk account). That's working well for me now.

I queried the myDisk folks if they would allow wedDAV for paying customers and here was the response:

"We had a discussion yesterday night about Zotero and how/if we should allow this for paying users.

We decided that paying users will have access to Zotero, as long as the server can handle it safely.

Meaning that, if you buy a 5GB account on myDisk.se we will allow you to use Zotero.
How ever, if we encounter problems that we can not longer server Zotero because of to heavy loads, we will close the access to Zotero again, and your remaining money for the period will be refunded to you.

According to the Zotero page, a 5GB account is €50 which is currently $67.39.

WebDAV syncing supplies two things:

• easy, automatic (and probably offsite) backup of your attachments
• a way to easily use those attachments from multiple copies of zotero (if you use it on a work/school and/or home desktop and/or laptop, for example).

If you are happy that your flash drive does enough of this for what you need, then you certainly don't need to use WebDAV

Great; Thanks :)

You can get now 2GB + 250MB for free from Dropbox (it's a campaign):
https://www.getdropbox.com

You can also use Dropbox as an unsecured webdav service, just define the storage server url as:
http://www.box.net/dav/zotero/

There is a piece of software you will have to install on your computer, though. But if you're using the dav connection, you can uninstall it afterwards.

EDIT: as noksagt kindly informs in the response below, there's a mistake there in my message, box.net (free 1gb webdav) and dropbox (2gb + 250mb non-dav service) are two different service providers.

The link above is a campaign referral link, true, with which one can get the 250mb extra space. My apologies, if anyone has been offended by that, you can most certainly get a dropbox without any referrals from http://www.dropbox.com

Zotero 2.0b3 should generate considerably fewer WebDAV requests for missing attachments than 1.5. It now only attempts to download files if another copy of Zotero has updated the WebDAV store since the last attempt on the local computer.
