I've used PFS for years (PFS, AFS, PFS2, PFS3) and never lost a file due to filesystem problem.
It supports drives upto 2 terabytes, providing the device interface (.device) support that large disk. Maximum partition size is about 100 gigabytes. I have a 96.4GB partition on my 120GB hard disk.
Another great feature is that PFS3 has working repair tools (not that I've really had to use them often).
However, the filesystem itself has nothing to do with partitioning the disk. You need to have working tool for that. For example Phase5/DCE SCSI interface has its' own tool: SCSIConfig. AmigaOS has HDToolBox, but it is known to have some problems with large disks before AmigaOS 3.9 version.
Also, NEVER try to low-level format a modern hard disk. NEVER try to format a partition >4Gig area without QUICK option. Always use QUICK.
