I do remember seeing it as a 500gb drive when I opened the Disk Utility the first time I successfully reformatted the drive. I don't understand why this is as it is a 500gb drive. the drive comes up as '2.0 TB WD My Passport' in the Disk Utility. It should also be noted that when I first connect the drive it makes about 6 clicking sounds as it is trying to boot and then sounds like it turns off when the 'The disk you inserted was not able to be read by this computer' comes up. I then tried partitioning the drive (with 1 partition) and clicking on 'GUID Partition Table' in the Opitions dialogue box and received this error: 'Partition failed with the error: Input/output error.' I tried formatting with each volume format from the drop-down and got the same error.

Switching back to Mac OS and opening the Disk Utility I figured I may as well try again to reformat the drive again, this time receiving the error: 'Disk Erase failed with the error: Input/output error'. I did not use the drive until a few days later when I connected again running in Mac OS, but this time an error message popped up: 'The disk you inserted was not able to be read by this computer.' The drive did not appear in My Computer when I switched to Windows. Things appeared to run smoothly, and I even copied about 10gb from my old external onto the My Passport. So I followed the advice of a few forums and opened the Disk Utility and reformatted the drive for 'Mac OS Extended (Journaled)'. When I connected the drive for the first time in the Mac OS it was recognized in the Finder but was not writable.

Since I run both Windows and Mac OS Version 10.4.11 on my MBP I wanted the drive to be readable and writable for both operating systems.

I recently purchased a 500gb Western Digital My Passport Elite external hard drive for my MacBook Pro.
