Yesterday I purchased a new Macbook Pro running Yosemite 10.10.3. I have an old (2006) WD 500GB My Book Essential that will not show up when I connect it to the Macbook. What can I do to correct tthis? Any suggestions would be greatly appreciated, thanks.
Welcome to the Community.
Is the hard drive detected within your Mac’s built-in Disk Utility diagnostic application? If so, does it allow you to repair the hard drive?
Instructions related to accessing Disk Utility are available in the following link:

If it does not show in Disk Utility, does the hard drive still work in older computer systems?
