Hard drive size problems

[theEclipse]

Hello,

I have dealt with this problem on pcs before but have not been around macs enough to have to handle this yet.

We bought an external hd for video editing. Its a maxtor 250Gb and the computer is a G5 imac. I know its os x but I am not sure which version (nor do I know how to find out).

The problem comes in when trying to partition the drive. OSX only seems to want to see 127.28Gb of the drive. On a pc I would check the bios to make sure that the drive is not configured improperly. Near as I can tell there is no customer accessible bios.

The other thing that is sometimes needed on PCs is a registry setting that allows drives larger than 127G.

I looked on maxtor.com for drivers but no luck. Hard drives dont usually require drivers to get the full size from the drive.

Thanks for any help

Did you first format the drive in HFS? Could it still be in NTFS or FAT32 format?

jimoblak-

thanks for the reply. To start with the drive was unformatted (brand spankin new).

After afew hours on the phone with maxtor and then apple I think I have the problem figured out. We are using an external inclosure and its firewire. Problem is that its firewire 400. Firewire 400 is unable to use 48bit addressing that is required when refrencing data storage > 127.78Gb.

I ordered a new enclosure, we will see what comes of it.

Thanks again.

I have a 250GB external drive (partiioned) on an older iMac with Firewire400 so I am not sure if this is right. Hopefully the new enclosure helps.
