I have a 1.67GHz Powebook (rev E, later 2005) running OS 10.4.11 which I use to run video mixing/playback software. To improve playback performance I want to run the video files from an SSD and I happen to have a 128GB Kingston SATA drive in a USB enclosure available. However, the Powerbook refuses to see the drive. I have tried it with a Macbook Pro (OS 10.6.6) and it's fine but with another Powerbook (1GHz, 2003, OS 10.4.11) it also fails to be seen. Kingston claim the problem is that Powerbooks are too old to work with SSD technology but this would appear to be rubbish as other people talk about using SSDs with Powerbooks. So, has anyone else successfuly used an external SSD with a Powerbook G4? Or, has anyone actually used an internal SSD successfully for that matter?). If the answer is 'yes' then is the problem I am having likely to down to the specific SSD model, the OS I'm running or the fact that it's in an external USB enclosure?
