DaveLembke,
I trued off index for all drives and it still has a short flash
Yes, if it is playing music I don't think about the drive light. When it has a resewn to flash, so I don't worry about it.
Otherwise when it is flashing and I don't know why, I become concerned.
My next guess would be the *censored* HP software is snooping around to see if I want to scan something or get an update or send a fax.
So I could either un install all the HP software, or listen to some soft music.
