Did you try just rebuilding the desktop on the CF card after the copy? (Restart with cmd + option held down)
Could be just an icon display issue. I don’t see how a simple file copy could bork the type/creator, though I thought the same thing (pretty sure it’s zsys/MACS)
Solved, probably an issue with MacOS X, using the Clamshell and MacOS 9 had the icon looking fine.
Moving the System file in and out blessed it for good.
The PowerBook 1400 is booting from the CF card… hard drive is dead in this unit.
I missed the hard drive noise, so in the end fitted another drive and made a copy of the CF card to have a working unit.
But as i had another CF card in a drawer, made a copy of the Clamshell drive.
The 1400 can boot 8,5 or 9,04 if needed.
