Reconnecting synch to external drive?
Because my haddrive lacked space, I set up Dropbox to synch to an external drive connected to my MacBookAir. However, whilst travelling I disconnect the portable (external) drive and when reconnectin...
OK, here's the fix for Mac. First, rename your existing folder of files on the external drive, I chose something appropriate, "ScrewedUpDropbox." Then start from ground zero, quit DB and toss the folder it created on the system drive. Startup and relink to dropbox, let it create that folder on the system drive again and as soon as it starts syncing, pause it. Go to Preferences, change the dropbox folder location to your External HD and hit OK through the prompts. Wait for Dropbox to do its thing reloacting the folder. Before unpausing, go to the external drive in the finder and move all of your folders in "ScrewedUpDropbox" into the newly created "Dropbox" folder that's now there. Then unpause syncing. It will resync to all your files without copying, takes a fraction of the time. Whew!
I have been having the same problem with my dropbox - on a Mac OS - for the past 12 months. It's fine for me to close the dropbox app then disconnect the external drive, then reconect the drive before opening the dropbox app. BUT, when I have had to reinstall the dropbox app, the DB app will not allow me to reconect the folder pathway. It forces me to resync my entire dropbox to the user, or to allocate a new folder within the external drive- a process which can take up to 3 days because of the size of the company dropbox.
See attached screenshot.
I'd really like to be able to just relink the dropbox pathway to the folder that already exists on the drive...
Thanks.
After 3 hours of trying to resync the dropbox on my Mac Os' external hardrive, the fix was something really unexpected.
I closed the dropbox desktop app and deleted the new directory it kept trying to create to my user folder. I prepared to rename the Dropbox (ES) folder of my hardrive to (OLD) by highlighting the name so that I could start a 'new' sync pathway to the hardrive - then had second thoughts so clicked out of the name field. This is where the dropbox app gave me some strange results. Dropbox automatically opened a window asking me to relink this dropbox pathway, I was able to then use the advanced settings to relink to the current dropbox to the external location.
This seems like a really strange workflow - but that's what worked in my case. I have not tried to replicate the issue as I don't have time, and I'm afraid the result may not duplicate.

Glad to hear you figured this out in the end AdrianDoidge - thanks for keeping us posted!
What you described is normal actually, as when you wish to re-install (or re-link) the Dropbox software and want to avoid re-downloading all of your files from the server, you need to choose the "Advanced" setup option during the installation process. You will then need to choose the parent folder of the existing Dropbox folder as the location for this new install.
For example, if your old Dropbox folder was added to: C:\Desktop\Dropbox you would need to choose C:\Desktop and the client will try and create a new Dropbox folder - as it did in your case as well. When you're connecting with the same Dropbox account as before, Dropbox will detect the existing folder and will then prompt you to merge the Dropbox folder. Upon merging the desktop version of Dropbox will check the existing files and the server versions and update accordingly.
Please note that any changes made to the files in the Dropbox folder or on the web interface while the folder was "offline" will probably generate conflicted copies.
I hope this information helps clear this up and let me know if there's anything else I can do to help with this. Thanks!
Thanks Walter. I understand the advanced functionality - but unfortunately, the dropbox app gives me (a Mac OS user) the error message from my screen shots, and doesn't allow me to select the parent folder because 'the directory already exists'. I'm not sure why this is.
As a follow up to my work around solution (clicking in the folder's name field and allowing dropbox to recognise the folder). I unfortunately had to delete the dropbox from my drive because of permission errors that arose with every file within the dropbox. Dropbox no longer recognised my Mac user profile with 'read & write' permissions after the relink, which meant that for each file and folder (for an entire company dropbox) required me to reset the permissions. This is because my profile experienced an update which changed the identifiers.
I couldn't just change the permission of the parent and have it take effect, I had to reset permisions manually for each file and folder (or enter my password each time I needed to update a file). In the case of wanting to create a new file and save it directly to the dropbox - it was no longer possible. I had to save it to my machine, then move it to the dropbox, and then enter a password to allow me to write to the folder.
The result: Deleting the folder and recreating the pathway from the start seems to be the only realistic way to get a working dropbox folder. The resync will most likely take three to four days.
This is an issue that I seem to have every 4-6 months for a Mac user profile. If anyone finds a solution, I'd love to hear it for next time.

Thanks for the elaborate reply AdrianDoidge - much appreciated.
Sorry to hear about this cumbersome situation. One thing that crosses my mind is that something did not go well when un-linking and re-linking this particular device. The permissions' error you get is usually fixed by performing an advanced re-install. Following, you'd need to point your Dropbox folder through the "Advanced" options to your already existing one on your external drive.
One thing to note here is that our software can indeed be used with an external hard drive for as long as you can ensure the drive is always connected to your computer while Dropbox is running. Should the drive ever get disconnected from the computer while Dropbox is running there is a small chance that the Dropbox software will start deleting files before realizing that the entire drive has been removed.
Also note that for Dropbox to work best you should make sure that the drive is formatted as NTFS (Windows), HFS (Mac OS X ) or a file system that supports extended attributes (Linux) like ext4 for example.
I hope this information clears this up a bit and if you have any further questions about this let me know and I'll reach out to you via email or go ahead and submit a ticket with our support team. Let me know a ticket ID if you do and I'll look into it ASAP.
Cheers!
