- Mac Pro 3,1 Dual Quadcore 2.8GHz 12GB Snow Leopard / G4 PowerMac (AGP/Sawtooth), 1.4GHz 2GB Leopard
A few days ago, my 2008 Mac Pro 3,1 suffered a totally unexpected flash-bang power supply failure as soon as I switched it on. Haven't had a chance to get the thing repaired yet (assuming there's anything left in there to repair - sob!), so for now I'm back to using my trusty, faithful 13 year-old G4 "AGP Graphics" machine that has NEVER LET ME DOWN (can you tell I'm a tad peeved, folks? ) This machine has two versions of OSX onboard: Panther 10.3.9 and - on a separate internal drive - Leopard 10.5.8
Eventually I'll get rid of Panther, but for now it's useful to hang on to, as I occasionally need to use some older apps that won't run under Leopard etc.
Now to the problem...
I have 2 external SATA HDDs in docking stations attached to the G4 via a USB2 card: one is a 640Gig that was formatted HFS+ (non-journalled) under Panther on the G4, and the other is a 2TB that was formatted HFS+ (non-journalled) under Snow Leopard on the Intel Mac Pro. This latter drive is also split into two 1TB Partitions.
If I boot the G4 into Leopard, it recognizes and mounts both drives.
If I boot it into Panther, it will mount the 640Gig drive, but when it detects the 2TB one it puts up the "You have inserted a drive that OSX cannot read" message.
As both drives are formatted HFS+ (and both show up as completely healthy under Leopard's Disk Utility), I'm wondering what gives here? Is the HFS filesystem as used in Snow Leopard significantly different from its previous incarnation, such that Panther can't understand it? Or does Panther perhaps have a ceiling on the maximum size of HDD it can recognize?
Can anyone enlighten me? I'd appreciate any ideas. Keep in mind that we're NOT talking drive corruption or loss of data here. Both drives and their respective file systems get a clean bill of health under Leopard.
