I'm a bit worried. I'm running Photoshop CS on my iBook G4 and couldn't save a file to the hard drive. Popup says "can't save file, "disk error"." File isn't crazy big -- 41.8 MB, just starting a project and doing a routine save. I repaired permissions as a start and still go the same response. Do I need to reboot after repairing? But I'd lose the file...... My temporary work-around solution was to plug in my iPod and use it as an external drive -- file saved perfectly. I then dragged it from the iPod over to my desktop. Cool, no problem, and the file re-opened beautifully. I'm glad I didn't lose the file but something is wrong and I'm worried.... any suggestions? Do I need to reboot after repairing? Running 10.3.7, 30GB hard drive, 256 ram. Hard drive is pretty full, but 8 GB are still free.
