As long as you have your master password (key) somewhere, you should be OK.

When my hard disk crashed, what I had to do was completely erase Hive from browser saved info (I also use Chrome), then try to log in with my master password... which will give you an ERROR message and ask you if you wish to download a PDF file with your keys. So you say "Yes," and store that file safely on your device. Then copy and paste the relevant key from the PDF doc and start over with which passwords/keys you are saving. However, I would only let Chrome save my Posting key... when I need to do financial stuff (like delegations) I do a manual copy and paste from my saved keys document... and answer NO when prompted whether or not I want to update my password.

It's why I now use KeyChain instead.
