Great article- I did want to give some background info.

For Drive Genius 2, we do indeed require that you update to 10.5.3 before working on your SATA-based drives. This is because Apple fixed a known issue in Leopard that was present in 10.5.0- 10.5.2 ..

There are a few mentions of the SATA AHCI problem on developer pages, and there had been a lot of discussion about this for the past few months…The good news is that Apple has indeed fixed this (the fix is in 10.5.3)..

Until that fix was released, we in essence had to put safeguards into Drive Genius 2 that prevented users from coming across this Apple bug. Now that Apple has fixed this bug in the OS, we have released a free update which checks to see if you have 10.5.3 installed, and if so, allows work on the SATA drives… If you have Tiger installed, that works fine too. However, if you have 10.5.0- 10.5.2, you will need to update to 10.5.3 as that has the fix from apple that is needed-

In looking at 10.5.3, it is indeed surprising how many bugs/issues Apple fixed, and those fixes are indeed important for many applications.

If you or other readers have any questions at all, please give us a call or email–
