Partition Size Not A Multiple of 4k

I had this issue and I just got my WD 640GB external drive from a Blackfriday deal recently and I was trying to format it using my Mac and I encountered some challenges but I finally found the solution by searching this keyword on Google "Partition size not a multiple of 4k"

I do not take credit for this guide but whoever did this is awesome. Saved me all the trouble and frustration.

When formatting an external HD today [Mac OS Extended Journaled(HFS+)] I ran into the following error.

“partition size not a multiple of 4k”

after a quick google search, i found the following fix:

“When formatting using Disk Utility, remember to select GUID Partition Table as your “partition map scheme” instead of MBR (Master Boot Record).”

basically do as follows:

1. open disk utility

2. select the drive

3. select the “partition” section

4. under the volume scheme select the number of partitions required

5. select the “options” button

NOT

7. click apply

you now should be good to go and the drive should function correctly. yay!
