Mac users have questions regarding doing this update on Macs, and MacTech
has secured the answers.

Q: Can I update the firmware on my Barracuda 7200.11 drive if it is
installed in a Mac?

Yes you can, but it has to be an Intel based Mac (i.e. MacPro and iMac –
with Intel inside). There are other models of Macs that have Intel
processors like the notebooks (MacBook and MacBook Pro) and the Mac Mini,
but these drives have notebook (2.5 inch) drives which are not affected.

Q: I have a PowerMac. Can I update the firmware on my Barracuda 7200.11 drives?

No. Older Macs that are PowerPC (PowerMac G3, G4, G5 and iMac G3, G4, and
G5) based cannot boot up to the FreeDOS. FreeDOS is the operating system
that is used when booting to the firmware update CD.
