Can I run more than one version of PFS-2 ?
Some people want to try a new version of PFS-2 on a single partition to ensure that all is well. This is possible for the Pro version. The user version will think you are trying to get around the imposed limits !
Before you attempt this you should ensure that your RDB is large enough to hold two versions of PFS-2.
You should follow the instructions for installing PFS-2 as given in the manual except that instead of specifying the ID 0x41465301 you should use 0x41465309. For each partition you want to use the new version you should go to the partition window in HDToolBox. Select advanced options and then select change. Clock on the file system button at the top until AFS\09 appears. Select OK. Select OK. Save changes to drive. You will get a warning about trashing the data. HDToolBox assumes that you are installing a new file system. You are not. It is safe to ignore this warning. You will have to reboot for changes to take effect !
When you are happy upgrade PFS-2 you should delete the 0x41465309 file system and upgrade the 0x41465301 version. All partitions should be switched back too.
