UW SCSI Drives!

[mdivancic]

I been slowly using up my supply of SCSI drives over the years. However I've got an almost unlimited supply of UW SCSI 3 drives as work phases them out for newer drives. Some are even new as they were kept around for backup. I got one of these:

SCA 80 to SCSI

It works! As long as the SCA 80 drive has a jumper to switch it to narrow the drive mounts and can be formated! I've been living with small drives for years, now I've got 9G and 18G drives at my disposal.  What partitioning schemes do you guys recommend for such large drives? I'm not planning to boot with these (yet), but I've got tons of backup space all of a sudden!

Try SFS ..?

Or do the Ethernet/NFS thing  :-D

[matthey]

Yea, those UWSCSI drives are cheap. I picked up a 16GB 15k drive that claimed to be new for $10 off e-bay. I get 30MB/s now on my CSMK3.

I also recommend SFS. You should have AmigaOS 3.9 also. Keep your boot partition under 4GB. 1GB or less is most practical. All the other partitioning is just preference.

You should use the old version of SFS:

http://www.xs4all.nl/~hjohn/SFS/
http://www.xs4all.nl/~hjohn/SFS184.lha

With it you are unlimited in partition size and location because it supports SCSI directly. Direct SCSI support has been removed from later versions of SFS.

This Thomas dude is way cool, just had to say it  :-)

I'm a fan as well :pint:
 
@ easy_john

The old version of SFS you want could be in his link above :-)

these remarks always make me wonder - what kind of things are some people doing with these "large" drives ?
I have never been able to fill up a 2gb drive on my Ami - not even half of it.

I'm really curious.

I do have games at least 20GB.

24Bit is bigger still.

RE your Boot Partition, keep it as small as possible & only install your choice of OS there. It's easier to maintain/defrag/repair if you install programs & utilities to other partitions. Thomas might be able to extrapolate a little further here & I recall boot Partitions need to be in the first 4GB of drive space (maybe 1 GB) irrespective of File System used. 120/150Mb should be more than ample for a boot partition with an A4KD running OS3.9 & maxxed out using PCI, Zorro Cards, etc!

lol I have 3 GB on a DVD that is just for Apps and things i need to install after OS3.9..... not to mention all the WHDload games and others easy 15GB+.....

HMMMMM i have a bunch of new 74GB i "Aquired" after i upgraded our server............. maybe its time to use them.....

A little bit offtopic, but will this adapter work on a Blizzard ppc with Scsi, it got scsi:

Fast SCSI2 controller (NCR 53C710)
MiniDB50 internal, Centronics 50HD external SCSI connector

Sure is alot of these drives floating around now...

I also have purchased several of those adapters and have used them to connect to a few SCA 80pin SCSI drives and the 50pin controller on my WarpEngine accelerator and they have worked well.

A bit off topic, I have purchased a 68pin CDRW drive and a 68pin 73.7gb hdd from an A.org member, as well as several 68pin cables and terminators from other members here, but have not been able to get the hdd setup to use with either of my CSPPC systems.  The CDRW is seen in the CSPPC early setup menu, but not the hdd.  A friend thinks it might be because the drive is an LVD device and I don't have LVD terminators.  Can anyone confirm what types of 68pin hard drives will work with the CSPPC controllers.  My goal is to have ONLY 68pin devices on the cable connected to the CSPPC SCSI controller so that it will run at the fastest speed allowable and not be slowed by any 50pin devices on the chain.  I would like to have one 36gb or larger hard drive plus the 68pin CDRW and that is all on the CSPPC SCSI controller, so if anyone can explain to me all the differences between Ultra 160, Ultra 320, Ultra Wide, Ultra Narrow, LVD, SCA, will 80pin to 68pin adapters slow the data rate possible if I use an 80pin hard drive and the 68pin CDRW as the only two devices on that controller?  Should I just give up trying to use the 68pin SCSI controller on the CSPPC card and waste a Zorro3 slot to put a FastlaneZ3 memory & SCSI2 controller card into?

Trying to build one ultimate Classic Amiga with all the bits and pieces I have collected over the years, plus the Deneb and IndivisionAGA 4000 I just purchased a month ago.

All suggestions gladly considered.

I use a 300gb U320 drive on my csppc. I have an active terminator on both ends of the cable. I have a bunch of scsi1/2 devices too including cdrom etc. The main drive runs at full speed. Only problem I had was when I had two U320 drives and I had to remove the active terminator from one end to get it to work correctly with both (although this was only the case with a certain combination of drives). No idea why. The csppc termination stuff seems to be quite random sometimes ;-)

Thanks for the quick reply, can you describe your SCSI chain now?  Do you have only the one drive on your CSPPC controller, or do you have multiple hard drives plus the CDROM connected to it with the 300gb U320 being one of them?

I have tried several different active terminators and tried putting them in different locations, plus I have tried to use the active termination jumper on the drive itself and still I have not been able to get the drive recognized yet.  The drive should be good, as I got it from a member here and he assured me that it worked on his system, which I think was also a CSPPC system.  But, I have pretty much resigned myself to getting a different hard drive and trying again.  I have even tried it in a second CSPPC system with the same result of no results.
