USB Hdd Problems

I have a USB harddrive that works on mac 9.1, but as soon as i switch to mac OS X it says that it cannon read it. What do i need to do?!

Is the USB port built in or an add on card? What is the current format of the drive?

You may need to reformat the drive on OSX to make it work with both.

I reformatted it now, it was formatted for windows, but now it cannot be read by windows. it doesn't show erase disk to DOS, only MAC Standard and MAC Extended. I really need it to be legable by both.

Are you formatting it in OS9 or OSX?

Use a PEECEE to format to FAT32 then it can be written to and read by OSX and Windows. Don't know about os 9.1 though.

How big is the drive in question and what version of Windows are you using?

It's 80GB, i managed to partition it as free space to its full (74.5GB) using mac OSX, and then format it to DOS as "74.5GB, but now when i plug it in, it is 10.5GB. the computer can read it, but such little space is useless...

Try reformatting it with OSX and see if it gives you an MS-DOS option this time.

To be able to format it as DOS i have to partition it as "free space" first, and when it is in this state OSX cannot format it.
