disc erase failed with error invalid request
HI,
I'm trying to get a new 2.5tb external wd hard drive to work with both my mac and my old pc - so i can backup my old data from the pc.
i have tried using disc utility, and erasing the disk and reformating to ms-dos (fat) format and recieve the following error message:
Disk erase failed with the following request: invalid request
i have also tried partitioning the hard drive, and recieve the same error message.
Any ideas on how to re-format this device?
Thanks!
