Before installing Mac OS Mavericks I wanted to upgrade the firmware of my about 3 years old My Book Studio Edition II drives. I followed all instructions, but when running WDFirmwareUpdater.app I got the message:
The operation couldn’t be completed. (NSURLErrorDomain error -3003.)
But I could continue the firmware upgrade, so I tried it. Unfortunatel in the end I got the message:
Firmware update failed
Unable to find device to update. Check your cable connection, and then run
WD Firmware Updater again.
Click Exit, and then run the WD Firmware Updater again.
Repeating didn’t help. What can I do? Many thanks!
BTW: 3 things were not clear: During the upgrade:
should WD Drive Manager be running (or quit?)
should the drive be mounted (or ejected?)
should the drive be on (or switched off?)
Where can I show/see which firmware is currently installed?
