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
- 6. make sure “GUID Partition Table” is selected NOT “Master Boot Record”
- 7. click apply
you now should be good to go and the drive should function correctly. yay!
