I upgraded my account, and now the desktop client is not letting me login, saying I need the latest client. I downloaded that and it still gives me the same error..

You'll need their "experimental build": https://forums.dropbox.com/topic.php?id=66910

That is pretty horrible UX. Why would they enable it in the web UI, but make you look at a forum post to get the build you need. Also, without linking to it when you get an error on the build?

Put a truecrypt volume in your DropBox. Why rely on someone else to do the encryption?

The downside, of course, is no differential sync'ing. So, if you make a change to your volume, you must re-upload the entire volume. Worth doing for some files, yes, but still a pain. Per-file encryption would be ideal, but a monstrous pain to implement with TrueCrypt. Dropbox is probably not crazy about widespread encryption because it would eliminate their ability to perform deduplication. Perhaps they could get ar…

If you only change a few kilobytes, dropbox only has to upload a few kilobytes.

I just modified a file in a 64MB truecrypt container and unmounted it. Dropbox took roughly five seconds to sync it.

The only real problem with truecrypt in dropbox is that you can't keep it mounted on multiple devices.

Does anyone know where I can download the latest Linux binary that support 2 factor authentication? I tried downloading the linux version, but it keeps on saying "this account uses two-step verification. To link to it, please download the latest version of Dropbox from www.dropbox.com/download". Maybe there is no new linux client, not sure.

The feature seems to have been released to forum users, then submitted here by a third party. I agree, though, there should have at least been a notification when the feature was enabled to read the forum post.

What do you know, you're right. I am impressed; I was under the impression that because of the encryption, Dropbox couldn't reliably determine what pieces changed.

Two-Factor authentication sucks. It's too hard for users. Most people will never us it. Dropbox should consider using Rublon (yes, that's my startup): https://rublon.com 7 reasons why you should add Rublon to your website: http://blog.rublon.com/2012/why-add-rublon/

It must be easier to build a startup on the assumption that your users are incompetent mouthbreathers. Respecting your users is hard work :-/

Sorry for the confusion, this was a forum release. Linux build is here:

Truecrypt is designed to work on a block-by-block basis or else it would be horribly slow at everything. So dropbox's job isn't harder than any arbitrary binary file with a few KB changing. Easier, really, since nothing changes size and shifts the data after it.
