I have an external 250 GB SSD which now, when I connect it (via USB) to the computer, causes the OS (10.10.3) to prompt me with:

Enter a password to unlock the disk

The problem (well, a problem) is that the disk is not encrypted with FileVault. It does have an encfs filesystem on it, but that's in addition to regular non-encrypted files. So I don't know the password because there isn't one. (The encfs password does not work, when entered.)

Running Disk Utility's "repair volume" on the partition in question tells me that the journal needs to be replayed but the volume is read-only.

Is there a way for me to at least mount the filesystem read-only, ignoring the journal and taking my chances? I would of course ideally just like to repair the volume, so if that's an option then I'd love that.

    Can you post a screen shot of the Disk Utility sidebar? – William T Froggard Jun 16 '15 at 17:47
  • Done, edited question to include it. – Jeremy Jun 16 '15 at 20:36
  • Please eject the 4 TB aurex drive and add the output of diskutil cs list as well as sudo gpt -r show /dev/disk0 and sudo gpt -r show /dev/disk1 all entered in Terminal to your question – klanomath Jun 16 '15 at 20:54
  • Done, and thank you for asking. I addded gpt output for /dev/disk2 since /dev/disk1 seems to still be a placeholder for the ejected aurex volume. I didn't know about either of those commands before! – Jeremy Jun 17 '15 at 18:45
  • @Jeremy Which of the two encfs implementations did you install? EncFS or EncFSMP – klanomath Jun 17 '15 at 19:26
