I am having the same problem with my external hard drive. DAE error 9060 will not let me work pro tools. If anyone knows what the problem is I would be grateful.

Have you guys checked the Digidesign Answer base yet?

I´m not usre now, but are you guys using old drives? I used to have this with older slowwwwwwwww drives.
Also: are you guy into heavy edits? Try consolidating, bouncing jammed tracks.
Go to preferences and reduce the maximum recording time. This will reduce the time it gets to access the HDs. For example, if you plan recording a song around 5 minutes, set this parameter to 6 minutes or so.
Defrag your Hds weekly also
Hope it helped ya
( Who would say I would be...) -lol
