My Mac OS X doesn't recognize my Maxtor One Touch

You need to determine whether the drive is OK. I suggest trying the drive on another computer before you move on.I trust that you have re-booted the mac? Also try a different cable and USB socket just to be on the safe side.
I hope I have been of help but please do not hesitate to ask if you have any further questions.

FORMAT AND CONNECT TO PC IF NOT RECOGNIZED MAY BE BAD HARD DRIVE . OR NOT COMPATIBLE

Yes, macs and pc's use different file systems.
You would need to reformat the drive to fat or ntfs for it to work on the PC.

Probably not the right answer for your problem. Mine is an external 1 TB Simple Drive. Mine wouldn't respond at all. I unplugged the power cable from the back of the hard drive and replugged it in and instantly it worked. I had tried rebooting the computer, plugging/unplugging over and over into the computer and that didn't work.

go to my computer proeprty then uninstall usb driver and then right clik any driver then clik on scan for hardware then it searches usb and install automatically.

To isolate the problem, please try the steps below:

1. Make sure that the USB ports of your PC are working.
2. Try to connect the device into different USB ports.
3. Try to connect it into different Windows based computer.

Question: Did you reformat this device using your Mac? If yes, there could be a possibility that the device was reformatted using the Mac OSX (Journaled). This type of format would only recognized by Mac computers.

But if it's formatted using the DOS based system, it would work on both Mac and PC.

check to make sure the drive is formatted to the FAT file system as NTFS file system is not recognised on Macs (check the drive on a PC and have the PC format the drive to the FAT file system)

take ur device and throw it in nearby river

If files you are trying to restore are encrypted you will have to use same software to retrieve them.. If not, any file in the external hard drive should be viewable with your windows explorer.

And U do not need drivers for external hard drives. They just plug into your usb port and work with modern OS after the unit is recognized.

Does Windows recognize that there is anything plugged in at all?

If not it could be your USB interface (on the Maxtor) is shot.
