How to partition an external drive using Disk Utility

Outlook users that need to rebuild their Identities that do not have enough free space on their internal drives will need to use an external drive with enough free space for the rebuild.  I recommend a minimum of 300 GB free.

If you purchase a new drive, be sure to format it first using Disk Utility as Mac OS X Journaled. The drive must be formatted as GUID Partition Table to be bootable. I would not partition and use the entire new drive for the rebuild. You can always add a partition if needed after you complete the rebuild.

If you have an external drive that already has files on it but does have enough free space, use these steps to add a partition for the rebuild.

Using Disk Utility, select your external drive and add the largest partition available. I suggest a minimum of 300GB free.

  • Open Disk Utility
  • Select the disk where you want to create a new partition and click Partition
  • Select an existing partition in the Volume Scheme list, and click Add (+). Disk Utility splits the partition into two, leaving the data from that partition in one of the new partitions. If the partition is less than half-full, Disk Utility creates two partitions of equal size. Otherwise, it creates one partition large enough for the data, and another partition with the remaining space.
  • Resize the partitions as needed. You can drag the dividers between the partitions in the Volume Scheme list, or you can select a partition in the Volume Scheme list, and then enter a value in the Size field.
  • If this drive has never been used, choose a format. Select a filesystem type (Mac OS Extended Journaled is default). The drive must be formatted as GUID Partition Table to be bootable.
  • Click Apply.
  • See Disk Utility Help for additional info.

When I made my recovery partition, I used my Seagate 2TB that holds my clone backups for old OS X installs. I added a partition by selecting the bottom partition “Virtual” by clicking on the + sign.  If you no longer wish to keep this partition after recovering, you can remove and give the space back to the drive.


Use Search in Apple Mail

Mail uses tokens. From, To, Date, Contains etc are called tokens. More Info under Smart Search

I find that trying to enter multiple tokens in the “Find” box is difficult to see and manage since the search box fails to expand. For complex searches, follow these steps. This will bring up a search that is easier to use. For Entourage & Outlook users this should look more familiar.

1) Enter the person’s name. Select From, To or Entire Message. (you can enter any criteria to get started)  Alternatively, select New Smart Mailbox under Mailbox in the Menu bar.

2) Click on Save. I find this window to be easier to customize.

Continue clicking on the + to add criteria.

This last part is where Mail is not as elegant as Entourage or Outlook. You don’t see results without saving. This results in a smart folder added to the folder list.

If you decide to keep the smart folder,  you might want to create a template so the name is generic rather than a person’s name.

I used from criteria so it would not come up with any results for the template and the name would be search for my sidebar smart folder name.

Entering the from name field does not bring up results like the top search box so you would need the correct spelling for name.


To create a new search select to Edit Search by Control-Click (Right-click) on the Smart folder or select Mailbox in the Menu bar > Edit Smart Mailbox…
