Can't format external HD

[gavsko]

I was given a 2.5" USB Sumvision SATA drive by a PC friend of mine. On
the box it says it will work with OSX. When I plug it in it appears on
the desktop but I cannot format (the options are greyed out in disk utility) or copy to it. It's currently in Windows NT format (which I know the Mac can't copy to). I don't have anything like Norton that could possibly help.

I run a G4 quicksilver 10.3.9 (old I know).

Am I missing some software or is my kit to old to run SATA?

Should I just give him his disk back and say thanks but I don't really
need it?

First off, Quicksilvers only have USB 1.1 @ 12Mbit/s so a newer USB 2.0 to SATA adapter would drop to the old speed from 480Mbit/s.

It's too old to run it in the original configuration.

 

[Cave Man]

In Disk Utility, click on the hard drive (and not the Windows volume that is below and indented), then click on the Partition tab and select your number of partitions from the pulldown. If you want to boot from this drive, you have to select GUID for Intel macs or Apple Partition Map for PPC macs from the Option button.

All sorted, had to get it formated again on a PC, then all OK to format on the Mac. Why? Who knows.
