HELP... I have fitted a Maxtor 250GB sata drive to my G5 and it wont read it at all. I sent it back and got a replacement AND it wont see that one either. It runs an 80GB dribve fine. Anyone out there got any ideas?

What do you mean by it can't see it? Have you used the Disk Utility in your Utilities folder and formatted the HDD?

The first thing to do is check that the cables are all connected properly. There should be a power cable and data cable. Check that the data cable is connected to the motherboard properly.
You could try connecting the 250Gb drive to the cables where you have the 80Gb drive (since you know that there isn't a problem with the 80Gb). Just take the 80Gb out and put the 250Gb in its place.
Then you need to check in Disk Utility. You can get to Disk utility from Applications/Utilities in OSX. Or you can boot from the OSX install disk and select disk utility from the pull down menu.
If the drive shows up here, you should be able to format it, without problems.
Hope this helps. If not, give us some more details

I read elsewhere in this forum that some Seagate drives 250Gb and larger have problems on Macs. It can be fixed by putting the drive in a PC and changing a setting. But I can't find the link now. Perhaps a search on SATA Seagate G5 and 250Gb would help?

The problem mentioned elsewhere is high-capacity Seagate drives with SSC enabled. Most Seagate drives don't have SSC enabled by default, but a few do. The SATA controller on board the G5 can't handle these disks.
The solution is to put them in a PC and use a utlitilty to disable SSC.
