replace a hard disk

It is a Seagate 2Tb 7200rpm SATA II

All bets are off

The problem is since I changed by accident all de privilages, including the systeem files

I changed the system harddisk to a new Seagate 2Tb SATA II; install OSX 10.5.8

The PowerMac is like reborn by running the start-up disk in the "B" postion (lower)

Then I replaced the second disk too with a same, new Seagate 2Tb SATA II

The hard disk in the "A" position of the plate rack is not recognized by the Power Mac and remains invisible.

I changed both disks; withe the same result

What to do?

Yes that's right, it is more strange, when I change the position of both egal hard disks from A to B v.v.

Both drives come with OSX 10.5.8

Both drives appear in Disk Untility, but not together

Always that drive, wich is moutend in de "B" position (lower)

With "System Profile" the same result; only the disk in de "B" postion appears

How to inspect the cable connection to on the Logis Board ?

Is it possible the probelem has something to do with the change of all de privilages during the situation with the old standard drives ?

Thanks

Tomorrow i try to inspect the cables

In Holland it's now 22.50 PM

Thanks for all the instructions.

I have inspected the connectors (off and on)

No change, still the disk in the position "A" does not apear in the finder.

I still do not understand, what's the reason of the problem with the disk in postion "A"

This will take some time.

That's no problem, but tomorrow I will give you feed back.

Solution of the replace-problem hard disks PowerMac G5 Quad

It turned out that only the new 2TB drives were not recognized in position "A" or the "B" position.

The original standard 500Gb (Hitachi) were well recognized in the positions "A" and "B"

Also a 2TB drive in "B" and a 500Gb in "A" are visible in the Finder;vice versa, it was only the 500GB disk is visible in the Finder.

AnyFix (www.anyfix.nl) found that:

* The PowerMac G5 Quad (late 2005) has an outdated SATAcontroller, which supports only specific hard drives

* The Seagate hard drive was thus not recognized by the PM G5,

Solution:

The new 2TB Sata drive has been replaced by a Western Digital hard drive.

Thanks for the support via the forum
