hi guys, I really should be working on a big work deadline but dammit I decided to get my SCSI2SD-v5.0a board working in my A4000:idea:
so set it up fine with the latest firmware update and setup 2 4GB partitions in the utility program, saved and all fine. My A4000 and CS-MKIII finds both new partitions (using FFS) BUT I can only setup and partition the first 4GB. The 2nd 4GB partition is seen but it's parameters are blank? tried messing with the lowest cylinder and highest cylinder numbers and kept other parameters the same but was getting all kinds of conflict errors.
Basically is there a way to just setup the 2nd partition automatically based on the 1st partition on the SD card? did I forget to click on something as I'm assuming this is all from the SCSI2SD utility setup side & nothing to do with AmigaOS?

You might want to go back and verify the obvious stuff: 3.9 or 3.1 with the necessary patches to use larger than 4GB disks, latest version of HDToolbox, etc.

@ Oldsmobile_Mike
ya I think I'll just format the whole 8GB SD card as one partition as I've got OS3.9 with all the updates and I've already got a 'real' scsi drive plus and IDE CD too so this is just more storage.
So whats the best file system for these scsi2sd boards ??

I wouldn't do that, personally. Make a small partition (<500 MB) for SYS:, that way you'll maintain compatibility with any older software that tries to write to it. Then maybe a little bit bigger partition, call it WORK:, or whatever, since many Amiga programs expect that. I'd also create a separate partition to keep your games, and maybe one for backing up stuff, as well.
I use PFS, personally. Others swear by SFS. Good luck! :)
Edit: disregard that first paragraph if you're not using this as your primary drive. ;)

That will *not* work, not with 3.9 at least. The problem is the following: The ROM FFS and the ROM scsi.device will not be able to address any byte beyond the 4GB barrier, and hence will not be able to boot up your system, and hence will not be able to load the patches to actually *get* access to the additional space.
Chicken and egg problem.
You need a small boot partition that contains at least the ROM-Updates (or equivalent, e.g. scsi.device in DEVS:) and SetPatch (or equivalent, e.g. LoadModule), boot from there, and *then* once the system is booted, you will see the remaining partitions just fine.
Also, please make sure that you place the v45 FFS in the rigit disk block (HDToolbox can do that for you), otherwise the system will even attempt to mount your second partition with the old FFS, and will by that invalidate data on your first partition (outch!).

I just set up my 2 A2000 with that thingie, though I only use a 4 GB SD card, configured as *one* SCSI HD. Prepping and setup were flawless.
I'm not sure, but what youncall "partition" isn't an "partition", but a complete hard disk - for your Amiga! It doesn't know that those two 4 GB hard disks are indeed two parts on one physical SD card.
Are you sure you gave those "HD" each an own SCSI ID?
I must admit that I don't know how the usual Amiga SCSI controller work with *one* physical device at the connector that show up as *two* SCSI devices with *two* separate SCSI IDs. I always thought this kind of setup should work with *one* device ID and different LUNs.

Can you post a screenshot of your HDToolbox? Typically one hard disk = one device ID, unless it's something like a multi-slot card reader (in which case it would still be one ID, but use LUN's to differentiate the different physical card slots in the single device).

@ Thomas & Mike
guys this isn't my boot drive so no worries;) got her working great as one 8GB drive now using HDToolbox with my cybppc.device and right now just backing up some files and it seems quite quick but will check the speed once it's done copying

How did you go with the speed tests ?
I just got one of the new batches SCSI2SD V5 for my A500 with A590. Works well (so far). 7 and a bit GBs of HD space is handy on an Amiga 500.
I just want to get rid of the 40 Second boot up scan. Anyone got a way around that?
And mod the A590 to use the Amiga 500s power.
I've uploaded a blog of the setup narration here: http://amiga.org/forums/blog.php?b=4022
I get 1.02MB/Sec on a vanilla A500 with A590 KS2.05, WB2.1. I'm using a cheapy SANDisk 8GB Not sure if a different MicroSD card would make any difference to that.
My Aztec SCSIMonsterCF gets 1.4MB/Sec on the same Amiga Config.. But it has capacity limitations at 4GB and above. 2GB CF Cards seem to be the sweet spot for the monster.
Got to get around that 40 sec scan on start-up though. It only takes 8 Secs to boot WB2.1 once it actually boots.

from SysSpeed:
CreateFile 1.87 Mb/s
WriteFile 1.77
ReadFile 2.00
RawRead 2.12
nothing compared to my 'real' scsi drives connected to my onboard CS-MKIII UW-scsi but I'm quite happy with the speed/ no noise/ no crazy heat aspect of this scsi2sd card ;-)
btw, nice blog

you need to make the partitions slightly smaller then 4gb.
On my machines I make a boot partition usually in the 100-200 mb range, then a 800-900 mb partition for my apps (really oversized) then do the larger ones.
I never go over the 4gb since I don't do video and 4 gigs on an amiga is like 4 tb on a PC

There is no SCSI on board on Amiga 4000
So what kind of controller you tried first? I think that only FFS on kickstart 3.1 will limit partition size.

Anyone found a way to get around the 40sec startup delay. Its not the A590/A500 as the Aztec Monster only has a 10s delay on the exact same config. BTW. Pretty confident I've RTFM.
