Title: SFS / Partitions
Post by: Magicthise01 on February 14, 2013, 05:57:41 PM

Hi folks,

I have a bit of a noob question I'm afraid, and I can't seem to find a answer on the forum.

I have set up an 8 gig cf card in WINUAE and created a 400mb partition for ClassicWB and a 7.6gb partition for WHDLOAD ect. I used the SFS file system, followed the guide,set the transfer speeds, buffer & mask on both partitions and used the SFSformat command on both. In WinUAE, everything works fine - data on both partitions are accessible, but on the real machine (a1200 ks3.1) only the small bootable partition with ClassicWB appears. HDTools and HDInst can see the large partition, but I can't access it.

I was hoping somebody could let me know where I am going wrong?

Many thanks.

Shortly said, you have to patch scsi.device too to support bigger drives or use filesystem which supports direct-scsi.

Thank you all very much. I hadn't patched the scsi.device. :)

Thank you all very much. I hadn't patched the scsi.device. :)

Sorry to borrow your thread, but can anyone tell me why the patched scsi.device is much slower than the standard device? This is not terribly important to me as I use FastATA on my main A1200, but in the past when I've played around with the patched scsi.device on my spare A1200 I found it to be slow.

Has anyone else came across this?

There are several to choose from.  I found the one that Bloodwych demonstrates in his Video to not work at all with a Kingston 8gb CF, just causes it to guru and repeatedly restart!

So I guess you need to try a few and see which is best :)
