1) i no longer have access to CD-rom. what could it be??
probably the instalation of os3,9 keep the old cd driver for mounting a cdrom but because of scsi.device conflict it can't run properly. do you have any extra scsi or ide hardwear on the amiga? if not in the startup-sequence the setpatch must be configured like this: C:SetPatch Quiet
if there is a cd driver in Devs directory check if it is configured to use scsi.device unit=1 and CacheCDFS from L: directory.
2) MY 3 partition is actually SEEN on the WB screen, but i get a message saying: HD3 is UNRECOGNIZABLE. If i try to format it, after 1% i get a "scsi.device bla bla bla ERROR". So i cant use it!!
I tought that using together 3.9 & SFS i would be able to get full use of a 20 GB hard disk
you can have full access to all these even with os3,1 with the use of nsdpatch and a patched version of FFS. anyway the combination os3,9 sfs works fine on both my amigas, i install it recently and i don't have ffs anymore on the rdb of my disks. i format the partitions in full mode with the os format, in 1200 ide and in 3000 scsi hard disks and there wasn't any problem. the defrag tool of sfs works fine too. maybe the problem is from scsi device, if so the solution is the same to both of your problems.
