In the History section of the SFS_OLD.guide in the current aminet distribution (1.277), it says that from version 1.58 BETA, SCSI direct is turned on or off automatically:
"There is no seperate SCSI direct version of SFS anymore. SCSI
direct will be used automatically when no NSD 64-bit or TD64
support is found (SCSI direct users: please let me know if this
works correctly for you -- use the SFSquery tool to find out if
SCSI direct is being used)."
I know this was an old beta version, but does this still apply to the present versions 1.277 - 1.279?
I'm currently fiddling around myself with installing an 80GB on my other 1200 (68040/40/16MB WB3.1/3.0 ROMS) and it appears that using SFS 1.277 and frap
http://aminet.net/package/disk/misc/frap_v1.0 I am able to utilize correctly the full drive. Only requirement for frap is that ROM is in RAM.
I made two partitions of 1024MB, and a third of 72GB. This must be using scsi direct right? It seemingly works, but I'll have to do more testing within the next few days when I get the time. Check4GB says it's okay...
I also tried the scsi.device 43.24 instead of frap, but that appears to half the RAW read transfer speed in sysinfo to something like 1.1MB/s from 2.1MB/s where as FRAP seems to give a nice boost to about 2.3MB/s. Does anyone know why scsi.device 43.24 is running slow for me?
I'm aware of the cosmos scsi.device for use with PFS3, so I might give that a try as well at some point.
