Questions follow dots. The rest is history and system hardware/software.
It is an internal 3TB Hitachi drive that has 5 reallocated bad sectors on my:
- MacPro 5,1
- 3.33 GHz 6-Core Intel Xeon
- 24 GB memory
- OS 10.6.8
- Boot 200 GB SSD
Have prepared new drive - zeroed out, 1 partition, Mac OS Extended (Journaled), GUID, (also 3 TB 7200rpm Seagate Barracuda)
Currently: Me Read & Write, Admin Read & Write, and Everyone Read Only
- Want to add System - Read & Write. Is this necessary? Is best way via terminal or simple alternate way for non-geeks?
I don't rely on Time Machine, do frequent data backups, and clones of Boot Drive, and backups of User Folder; however still use Time Machine, just in case.
History: When SmartMon Tools told me 5 bad sectors, I panicked and thought maybe I should delete some of the older backups, as I saw drive was filling up; mistake #1.
When I realized it was a mistake, I tried to put back one of backups in Time Machine; but aborted that and managed to delete 3 backups from trash holding down option key.
Given this erratic behavior on my part and the failing (5 bad sector) Time Machine HDD: Is it best to start with fresh prepared HDD and just do a new clean Time Machine backup? (rather than cloning questionable old Time Machine HDD with CCC)
From research: Doesn't seem to be easy way to verify data (current backups) as it seems in 10.6.8 asking Time Machine to Verify Backups (with option key) only verifies that the Disk image is not damaged.
My new Time Machine HDD is currently in external bay. Plan to replace "failing" HDD with new one - internal on Mac Pro, once I decide how to proceed.
