External hard drive not detected or recognised

[br1anstorm]

My last thought on this is that the drive may be formatted as exfat. This was common a few years back on MS storage devices.

Thanks for your continuing interest!  But no, the paperwork confirms that it shipped formatted NTFS (the user leaflet even includes instructions on how to reformat for use in a Mac).

I think it's definitely R.I.P. for this deceased Iomega drive!
