Place a foot in the door. On each of your disks, create a text file, open it in TextEdit, add some line, and leave the file open unsaved. I think this trick will prevent ejection. Test this trick, try to eject the disk and come here tell us the result. This trick can easily be automated.

If your important external drive is mounted on the following mount point: /Volumes/important_disk Then you can protect it against an accidental removal by locking this mount point as opened. For this one very simple method consists in opening Terminal and doing this basic command: $ cd /Volumes/important_disk To get rid of this locking, you might type ...

Simply Turn indexing off for the drive and erase the contents of the journal on the volume. To do so, open Terminal and enter the following command: sudo mdutil -Ei off "/Volumes/Name_of_Drive"; exit You must run this procedure as an admin. Enter your password when prompted. A reboot may be required. Alternatively, as suggested by Simon White, just ...

This will not only enable you to safely unplug the drive, but it will ensure that the mds process restarts in case it is actually hung. If you have decided that you don’t want to use ...

Putting everything on the internal drive and using the external drive for Tim Machine will provide you with two copies of all of your data. That way if either drive dies, you will not lose much data. Also, a best practice for Time Machine is to keep the drive connected and mounted at all times. This way a backup will be done every hour and will always be ...

I'd suggest an application called DaisyDisk, it lets you drill down to each folder level to determine which directory is taking up all of the space. A lot of times, it's either ./MobileBackups or /private/var/vm. The former is where Time Machine stores local, offline cached backups, and /private/var/vm is where sleepimage files are kept. Those typically ...

The biggest issue here is that you need to run your analysis tools as root. If you don't do this, you'll only see the files that your account has access to, and so you won't see everything that is taking up space. I like GrandPerspective personally. If it's in your Applications folder, the command to run it as root looks like this: sudo ...

Short answer: Yes, you should. If your disk space needs are so small, it makes no sense to split them between two disks. By using the same disks, you will be able to store everything twice, so if any drive dies, all your data is on the second drive. I found it helpful to also backup applications, since sometimes updates remove functionality, and then it is ...

Carbon Copy Cloner [Bombich Software] might do what you need. Set up a new drive GUID/HFS+ Install a clean OS, same as the previous [safer as the state of the old one is suspect] then use CCC to copy the rest back to that new drive. Its default for restore is 'preserve newer, don't delete anything' which ought to neatly plant the rest of the data over the ...

Did you install the second hard drive yourself? If so then your best bet is to swap your SuperDrive back in before taking it in for service. I cover this scenario in more depth with this answer: Apple's warranty (AppleCare) is specific about what components are user replaceable/serviceable. The hard drive on an older MacBook for instance is user ...

Replacing your optical drive would seem a logic choice to me. No wires, fast transfer speeds and you have your disk always with you. If storage is your main concert, just go for an HD (And replace your SSD with a bigger one while you are at it...) It is not expensive at all. You need a philips screwdriver, a hard drive enclosure kit specially made to fit ...

To prevent Spotlight from indexing the drive, create a plaintext file in TextEdit with no content, just the title of .metadata_never_index and save to the external. Uncheck use extension "txt" ... and tell TextEdit that yes, you do want to save it with a dot at the front (which will make it invisible.) I'm not sure whether that will stop it right now, but ...
