>The 30 would likely migrate into an old PowerMac 6500/275 that needs >a new drive. This is the only question I have any experience with. When I replace my drives in my Quicksilver 733 and tried to install the original G4 40 GB drive in my Performa 6300, it didn't work. After researching the IBM drive, I found out that it would only work with a G3 or G4 Mac. You might check out the mfg. specs on the model of the HD you're planning to transplant and find out if it will work on the 6500. HTH Fred
