My external HDD

Hey guys, I just received my 1tb hard drive today but im having few problems.

I want to install it in Mac OS Extended so I can copy files bigger than four Gigs but it wont let me install, says there is an error but in FAT32 it formats perfectly.

Can someone help me out please.

Why don't you tell us exactly how you're trying to reformat the drive? Are you using Disk Utility? And what kind of an error is it giving you?

Regards.

The partition layout is probably set to Intel, you want to change this to Apple in Disk Utility.

hey guys, thanks for the reply although i managed to get it working.

through disc utility i went to partition, then choose "1 partion" and in the options selected GUID partition table which then allowed me to partition for MAC.

One thing though I wanted to ask:
my hard drive has an input for usb and power but no power switch, so basically im wanting to know if it self powers down when idling etc, or if i need to pull the power cord when im finished with it, thanks guys!

USB power is only present when your machine is turned on. So when you turn off the machine or put it to sleep, the external hard drive will spin down.

Regards.
