Recently tried to clone a 160GB external to a 40GB internal. Dumb!
The internal is a Seagate ATA ST340016A that was SMART enabled before I clobbered it. Seagate has some diagnostic and repair software thar is, unfortunately, totally PC oriented. Otherwise, their attitude is they're not into repairing drives as much as selling replacements.
I found nothing helpful at Apple's Support and Downloads web pages. My blunder seems to be a rare one.
I re-installed and upgraded to Mac OS 10.4.5 and then did a Firewire Target to get the drive running correctly - except that it imposes itself as startup drive upon Shutdown (Restart and Cold Start properly result in boot from external) and there are conflicting data about its SMART status. To wit:
Disk Warrior and TechTool Pro report that SMART is not supported. But when TechTool's Report SMART Messages is turned on, it periodically reports "Threshold Exceeded". Micromat's tech support says that said message is generated by the drive's SMART [!] firmware.
OS X's Disk Utility simply reports that SMART is not supported. But SMARTReporter shows the disk as verified (in text and with a constant green icon).
Most interesting, Mac HelpMate shows that SMART is not supported but its Extended Test yields:
smartctl version 5.33 [powerpc-apple-darwin7.5.0] Copyright (C) 2002-4 Bruce Allen
Smartctl: Device Read Identity Failed (not an ATA/ATAPI device)
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
The reference to smartctl and your being listed as home page led to this email. I didn't find my precise situation in the FAQs. Obviously, I'm a novice in this area but, since the drive appears to working fine (with the above non-fatal problems), I think some part of the drive firmware got overwritten in my misguided clone attempt, and, what needs to be done now is to re-install/restart/update/modify that firmware.
If I'm correct, can you tell me how to do that? If not, can you tell me what else I should do?
