I have a Western Digital My Passport (external hard drive) and I had been using it to back up my Windows XP machine. The XP machine's hard drive crashed, so now I am left with the My Passport drive.

Will I be able to load My Passport onto a Windows 7 machine? What about a Mac? Does anyone have any experience with this? Was it a bad idea to use the Western Digital My Passport software?

Any input would be great. Thanks!

You won't have any trouble reading the drive using a Windows 7 machine.

You shouldn't have any trouble reading the drive on a Mac either. If the drive was formatted using FAT32, which is likely the default, a Mac can read and write just fine to it. If it's formatted NTFS, which is the Windows standard, it should be able to read, but not write.

    Macs should read NTFS fine; you may need additional software to write to it. see this answer for more: superuser.com/questions/53633/… Oct 15, 2009 at 16:49
  • I actually found a similar question at the same time, and updated the answer to reflect that. Oct 15, 2009 at 16:50
  • But does "My Passport" store the data in its own compressed format? I am afraid that the crappy "My Passport" software will need to be compatible with the OS in order to read the data. Anyone have experience with this?

  • It's very doubtful. I've never used the software myself, but I'd expect it to just be copying data straight over to the drive. If anything, it'd compress it into a known format, such as .zip. I see no reason why they'd reinvent the wheel just to prevent compatibility. Oct 15, 2009 at 19:42

I found that my Western Digtal Passport WDXMS2500 is NOT compatible with Windows 7...I don't know why exactly. But it cannot connect...and who knows if it ever will.

  • That's not possible, unless you've encrypted the WD Passport.

  • According to WD tech support it will not work under Win 7 at this time. I didn't encrypt it either. Not sure what kind of magic they do on those drives...but I have moved to from Vista to Vista box with no problem but it does not work on two Win 7 machines I've tried to use.

    It seems quite unbelievable that an external USB drive would need special (non-generic) drivers. My own WD Passport works very well on Win7.
