FAT32 has several limitations, including a 4 GB per-file limit. Now, I am trying to use it on my MacBook Pro, and it lights up, its also recognized by my mac, I can see it on Disk Utility, but I can't open it.įor a hard drive to be able to be read and written to in both a PC and Mac computer, it must be formatted to or file format. I have a 2TB external drive called 'WD My Passport for Mac' It's been over a year since I last used it on my iMac. I set it up for my Quicken backups and so far have had no problems.


It was very stubborn and I resorted to formatting the drive. Hi there, JoeySmyth, just wanted to let you know that I first tried to delete the data that was on the WD My Passport. Most WD Drives come formatted in the NTFS (Windows) or HFS+ (Mac) format. This is useful if a drive is being used under both to move files between the two environments. This allows the drive to be used on both Windows and macOS.*END A Western Digital external hard drive can be used on both Windows and Mac OSX.

This answer explains how to format a drive in the exFAT or FAT32 file system.
