I have an iBook G4 which started crashing with -50 error codes last week, and has giving me heartache ever since. I had an issue with my internal drive performing a dissappearing act, and naturally replaced the drive and reinstalled Tiger.
That unfortunately did not fix the problem. The new drive installed fine, but the problems continued. I have since performed many tests, including TechTool, Drive Genius, memtest, and Apple's Hardware Test it provides directly to Apple Service providers, and have not had any indication of failure. I also have NO trouble when I boot this machine off of a firewire drive.
After much testing, i found that intermittently, once the computer has gotten a bit hot, the Apple Hardware Test that ships with my Mac has given me the following error code:
2STF/1/4: ATA-100-6-MASTER
My question is this: It seems clear there is something wrong with the ATA bus or controller in my iBook. Is that part integrated into the logic board or is available seperately? Is this what is to blame? According to the Apple Test, the logic board is fine, but it fails on the Mass Storage test and gives me the above code.
