Can anyone help me to understand exactly what disc arbitration does or how it works? I have lost my recovery partition twice now, have no idea how. Disc arbitration was listed on my Mac book pro system logs, lion op system, and someone said the using disc arbitration could hide the recovery partitions. Any info would be greatly appreciated.

Well, let's start with this: what third-party disk utilities, or partitions, or Windows VM environments are currently set up on your machine?

Surely you'd know this?
As for your original question, "disk arbitration" has to do with auto-mounting other disks (like when you plug in an external disk and after a moment it shows up on the desktop -- that's disk arbitration). There's someone else in one of the other sub-formums (switcher's, I think) having the same issue ... or maybe that's you? |

I am curious about Windows VM environments though. And your reply makes perfect sense!! Thanks.. Its just like an external disc is storing all my data on it therefore my recovery partition isn't visible since its being over road by this new disc ..... this is what my computer says, Hitachi HTS5450B9A302 Media Verifying partition map for “Hitachi HTS545050B9A302 Media” Checking prerequisites Checking the partition list Checking for an EFI system partition Checking the EFI system partition’s size Checking the EFI system partition’s file system Checking all HFS data partition loader spaces Checking Core Storage Physical Volume partitions Checking storage system Checking volume. disk0s2: Scan for Volume Headers disk0s2: Scan for Disk Labels Logical Volume Group 460F1631-38BF-47E5-BF5A-2DEAFC9B556E spans 1 device Logical Volume Group has a 16 MB Metadata Volume with double redundancy Start scanning metadata for a valid checkpoint Load and verify Segment Headers Load and verify Checkpoint Payload Load and verify Transaction Segment Incorporate 0 newer non-checkpoint transactions Load and verify Virtual Address Table Load and verify Segment Usage Table Load and verify Metadata Superblock Load and verify Logical Volumes B-Trees Logical Volume Group contains 1 Logical Volumes Load and verify 96C0CD19-B8F9-4F6B-8103-948A88C52893 Load and verify 33D7DDFE-B7A5-4EB8-9C3A-9D81AE3EEE02 Load and verify Freespace Summary Load and verify Block Accounting Load and verify Segment Cleaning Newest transaction commit checkpoint is valid The volume 460F1631-38BF-47E5-BF5A-2DEAFC9B556E appears to be OK.
