Anyway, salvation can come at no cost by using the Terminal in Mac OS X (assuming you have administrative rights): /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *250.1 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_HFS Iron Man 249.2 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *1.0 TB disk1 1: 0x EE 1.0 TB disk1s1 Iron Man:~ nbalkota$ WARNING: Improper use of the sudo command could lead to data loss or the deletion of important system files.
For a laptop computer that might be far from home, not having a Recovery Partition was unacceptable to me.
Also note that if you buy a Mac from Apple today with Fusion Drive, it DOES come with a Recovery Partition, so it is indeed possible to do.
This means that you can join just a specific data partition of your HD with an SSD, and leave the Recovery Partition intact.
I like to eject my external drives because they slow down my mac when they spin up, but I want to have an easy way to access them if I need to.
Thank you in advance - I look forward to your reply.
You can also install Cindori's Trim Enabler, available here.
When I click on "repair", it gives me the following details: Verify and Repair volume “disk1s3”Checking file system Checking Journaled HFS Plus volume.
Invalid record count Catalog file entry not found for extent The volume could not be verified completely. Updating boot support partitions for the volume as required. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Creating the Fusion Drive the way these walkthroughs say (including OWC's exceptional guides), destroys the Recovery Partition that exists on the drive.
