I am still having problems with my Seagate 2TB external disk my and back up 
regime as I mentioned in my email of 3rd June.   My usual method is to have 
Carbon Copy Cloner run an incremental backup daily.  The initial backup runs OK 
but 24Hrs later the incremental backup does not run with an error message 
saying "Could not find BU"  BU being the name I have assigned to the external 
disk.   The disk then failed to eject when requested saying  "cannot eject BU 
as a program is using it"   I presume this was CCC still trying to find the 
disk.   I managed to force eject the disk.   I have done all the obvious 
things, reformatted, run repair disk etc and I noted that when I tried to 
reformat initially I had a "could not Unmount" message which I overcame by 
clicking on the Unmount button.

I have tried running a Super Duper backup system and a similar problem 
occurred.   The initial backup ran with no apparent problem but the incremental 
the next day failed with the message "could not establish ownership of BU"

Can anyone spread any light on this problem or point me in a suitable 
investigative direction?

Thanks

Barry
