Then (while booted from your backup), format your boot-drive and THEN perform a "Clear Free Space" which will write controlled data to all sectors which might otherwise produce binary boundary errors that can transmit to another drive invisibly thru the OSX.
If you really need to be quite sure, first perform a bootable backup with "Carbon Copy Cloner" (or equiv). Even then, rare problems might not be caught. This must be looked at by a good quality 3rd party expert repair tool like "TechTool Pro", or "Drive Genius".

Disk Utility (even run from the OSX install DVD) cannot fix your kind of trouble. First, make absolutely sure your boot drive has no problems on it. SO WHAT DOES ONE DO WITH PROBLEMS LIKE THIS?ġ). It cannot be easily repaired after the fact. I realize this sounds like gobbledygook, but while this kind of problem is not common, it MUST be dealt with by prevention. Something is hinky on your boot drive (boot-drive is working because the system was installed without incident, but is not working on the secondary drive because problems that have invaded the boot-drive are now transferred to the secondary drive where the system does NOT exist.) This is why you are running into big trouble with your secondary drives. "Clear Free Space" on a secondary drive, done from a boot-drive tends to transfer any problems on the boot-drive to the secondary drive under test (this problem is quite rare, but it does happen). If you MUST "Clear Free Space" on an existing boot-drive with an existing system first perform a working Backup with Carbon Copy Cloner or equiv, then Format the boot-drive, then Clear Free Space, then Carbon Copy Cloner from Backup to boot-drive.Įven when "Clear Free Space" actually works with a drive that contains a system, drive performance suffers drastically, and one cannot easily get your original performance restored.Ģ).

The mapout table file is now the authority, and it's full of junk).
"Clear Free Space" not only writes clean tracks/sectors, but also tests and maps out bad clusters (that's why the drive becomes unusable if the routine FAILS before completion. This task is the only way to make sure that the newly manufactured drive is cleanly formatted and that all the media actually works (hard errors are trapped out by "Clear Free Space"). One only does this on a clean drive, newly formatted, and only on a drive you have recently bought new. Firstly, it is NEVER a good idea to "clear free space" on a drive with an existing system (anybody that says otherwise, is opening your system for obscure system or media errors that cannot be easily solved, better to stay away from it altogether, except to setup a new drive). Now let's see if we can fix this without getting really depressing !ġ). If your problem is hardware related, you are toast.

Sometimes it is bad media on the Boot-drive, sometimes it is bad software in the OSX, and sometimes it is hardware related.
I am presently the only Macintosh Technician in my town, and I've seen your kind of problem before. I've been doing computing since 1971, and my first decent personal computing ownership experience started with Microware OS9 (a UNIX clone) on a Radio Shack Color Computer 3.
