proper way to disconnect External HD with SuperDuper

[Greg14]

Hi;

I backed up for the first time no problem with a external Western Digital pro 500.

I have a laptop needed to take it and I put the HD icon in the trash and there was no problem.

I re-plugged the WD and the Icons appeared.

I needed to take the laptop a few days later and I did the same thing in that I moved the icon to the trash and when I removed the firewire plug a notice came on saying I was supposed to go thru the finder to disconnect the external HD and i may have lost some data.

Can you tell me or point me to a file that shows me the proper way to disconnect the HD
from the laptop


thank You

Greg

In general, I'd just use the eject button in the sidebar of the Finder. When you get the panel that says it's OK to unplug, unplug.
