Happened to me 2 years ago and righted itself, although I don't know how - Happpened again over the weekend.

External drive is a Seagate Freeagent connected via Firewire. PE7 will only work if the Seagate is turned off which is a pain as I hold all my source material in that drive.

Currently importing source material into the C Drive as a work around

Anyone else experienced similar?

Thx R
