ffs and large partitions

Can ffs from os3.9 handle partitions over 4 gigs, or do I have to go to sfs or pfs
thanks

Yes, no need to change filesystems in order to go over 4GB.

although it would be fair to say

1. SFS would be faster (as would PSF2/3) than FFS
2. You cannot use FFS tools like ReOrg or DiskSalv
3. Drive can suffer the Validation issues of FFS -

(validation errors on 4GB is pretty horrendus - but on somthing like 8GB is not a good experience!!! imagining a larger partition than that .... hell thats gonna take like a week to validate!

If you are running OS3.9 I can only suggest that you change your booting from FFS to SFS, its better in all respects that I have found.

Currently my A4000 is running CWOS3.9 - this is housed on a CyberSCSI 2 with an U2Wide 18.1GB SCSI HDD thats been partitioned and formatted for SFS.

Raw Speed Controller Performace - test (RSCP) designed by Russel Miranda - benched my system at 4MB per second 86% CPU idle running from "cybrscsi.device" and surprisingly 2.7MB from Native IDE "scsi.device" although the CPU was hammered with under 40% idle.

I will say that RSCP is an old program so it doesn't take into account newer CPU's or cache on Harddrives.
