Why does it take so long for my macbook pro to recognize my external hard drive?

I have a 15" macbook pro running OS X 10.5.8 and a Western Digital 1TB external hard drive. The majority of the time, it takes several minutes for my mac to recognize the device. Why does it take so long and what can I do to make it recognize it faster?


Answer
I believe it is indexing it before it will show up. I don't know how to make it quicker.

How can I make an external hard drive, be the main hard drive on my MacBook Pro?

You might know, the MacBook Pro with retina display does not have many gigabytes of storage. How can I make my external hard drive be the main hard drive I was when I open applications such as iMovie and iTunes that it will work the same way but run off of the external hard drive.


Answer
There is no "main" drive like on a PC. There is the OS startup drive and there are all the rest.

Definitions:
"volume" means a formatted partition, so it could be a second partition of the same drive or a different drive.
"startup volume" or "startup drive" means the one where Mac OS is installed and chosen as the Startup Disk. (Mac OS could be installed on more than one volume, but only one can be chose to start the computer.)

To run any app from a non-startup drive volume, copy that app to the preferred volume. Will that work or not, and are there any limitations even if it works?

â Some apps cannot run on any volume except the startup, but that is quite rare. The app may be able to work normally if it is at the root level of the volume, but other apps must be in a directory named "Applications" that is at the root level of that volume.
â Most apps can run from any volume, but may need certain of the app's support files added to that volume.
â The "Software Update" process that is part of the Mac OS will not work or will not work as you expect if the app that is out of date is no longer at /Applications or /Applications/Utilities as it should be.
â Time Machine can use any Mac formatted volume other than the startup volume as its backup destination, but can only make a backup of the startup volume.
â An external drive can be used as the startup volume, but it will be slower response than the internal volume. The slowest response would be from a USB 2.0 connection, and the fastest would be from a Thunderbolt connection. For your MacBook Pro, the startup volume must be formatted "Mac OS Extended" and can be on a drive that is either "Apple Partition Map" scheme or "GUID Partition Table" scheme (cannot bot to any "Master Boot Record" partition scheme drive). A Mac OS X installer running on the MacBook Pro cannot install on any scheme except GUID Partition Table.

As to your goal of using the external drive to extend your total storage, the media files (songs and movies) usually take up much more of the drive volume's capacity than the iTunes app itself. For strategy ideas, read the answer at the link below.
