Hi Tim,
I'm currently using a Quantum 105MB SCSI drive with my HardFrame 2000
and have had similar Read/Write errors occasionally as you do. Originally,
I had the Drive Partitioned into 2 Logical Drives and didn't have any
Read/Write Problems. But ever since I made 6 Partitions on my Drive, it
occassionally gets the Read/Write errors especially in very large files.
Clicking on the retry usually fixes it.
The Hardframe will autoconfigure your hard drive when you boot up so
that no mountlist entry is needed, though it is possible to use a mountlist
entry to manually mount the drive. As long as you use the RDPrep program
to configure the Rigid Disk Block area on your drive, you won't need the
Mountlist entry.
I agree that the documentation for it is terrible !!! The documentation
on the Installtion Disk called HardFrame.UserGuide should be enough to get
you through it. That is, if you accept the default parameters that it
SUPPOSEDLY reads off of your harddrive. Someone here in AmigaTech could
probably get you the Specs on the Miniscribe Drive, the same way I got mine
for the Quantum.
I hope you get your drive up running 100% like i'm trying to get mine!!
P.S. This weekend i'm going to backup my entire harddrive and reformat it.
Fun, Fun, Fun…….Here we Come ……

Kerry,
I'm at the same stage on my Quantum 105 meg HD. How are you going to set
up the new formats?
…Dave
Dave: I left a message earlier trying to get some information on the
Quantum 105 such as the number of cylinders, number of heads, blocks per
track, etc., but nobody answered so I'm still in the dark on getting the
drive preped and the mountlist ready. I'm using a 2090 controller.
Hopefully you will have
better luck than I did.

John,
Try calling Quantum. Phone # I have for them is:
(408) 262-1100
Don
Thanks Don for Quantum's phone number. I did find some info on Genie today
concerning the 105s so I was able to get the drive up and running. I like
the extra storage space and speed compared to my old reliable 8425S.
John
Don, I tried calling the number for Quantum that you posted. No luck,
recording said the number was out of service. I've been using a Q105S for
months and would very much like to get my hands on a Tech. Ref. manual for
the beasty…

Julius,
You might want to check with some of the others who have a Quantum
and see if they have a newer address or phone number for them.
Don
Hi John.
This is the information that I got from a recent Computer Shopper Mag for
the Quantum 105S Drive:
Name: 105S
Type: SCSI RLL
3 Platters
6 Heads
6114 Tracks per Drive (1019 Cyls x 6 Heads)
1225 TPI
20050 BPI
1019 Cylinders
3662 RPM
2MB/Sec Asy. Transfer Rate
19 ms Average Seek
8.2 ms Latency Average
If your looking for what to enter for '# of disk cylinders' question I
believe you should put 1019. At least thats what I had used in the past.
Good Luck with your HD. If you have any other questions, I'll try to answer
them.
Kerry
Kerry: Thanks for the info on the 105S. As I mentioned to Don, I was able to
get some information on Genie and this is what I used to set up my 105:
.
.Number of Heads: 2
.Number of Cylinders: 3203
.Blocks per track: 32
.
So if you figure 2 * 3203 * 32 * 512 = 104.956 megabytes. This might be lying
to the 105 drive but from what I understand about SCSI its very forgivable as
long as the total number of sectors come out the same. So far the drive seems
to be working just fine, knock on wood.

John,
I'm just flying pretty blind myself but that's ok, I don't know what I'm
doing anyway. Using a Hardframe 2000 controller, sure is great to have all
that storage space, ain't it?
…Dave
Yep, the extra space is nice along with the speed boost. See the message I
left to Kerry Foster concerning some info I found on Genie about the 105S.
Maybe this will help you get set up if you haven't already done so.
John
I got it, great stuff. I'll use it.
…Dave
Hi Dave,
I don't even know where to start on my Quantum 105MG HD. I had reformatted
it earlier to take advantage of the varying number of sectors per track on
the different parts of the hard drive and was actually able to get more
room out of the drive. Apparently, ADos doesn't seem to like the way that
I set it up. Running something such as DiskSalv doesn't pick up any errors
on the HD, but ADos has problems with relatively large files. I think it
has something to do with when the file crosses a track boundary perhaps. I
may try to find out what the problem is first before I reformat.
But as soon as I reformat I can go through the fun part, deciding on how to
set up the partitions. I had it originally set up with only two partitions
and had trouble keeping track of all the subdirectories. Now a days, I
have six partitions; 1 for the system stuff, libraries, etc.; 1 for the
utilities I use; 1 for term programs and downloads; 1 for a few games of
which I play very little of; 1 for experimental stuff, new programs that I
play around with; and the last partition I want to put my C compiler stuff
in as soon as I buy it.
Any suggestions on how I should reformat it ? BTW, do you have any idea on
how much room Lattice C takes up so I can make a big enough partition ?
Well, it looks like theres fun times ahead for the both of us !!
Kerry
Kerry,
I wish I knew enough to answer some of your questions, but I'm learning
slowly but surely. I'll be watching to see what you come up with. The one
thing I have picked up is that you should have one fairly small partition
that is for your Workbench set up and then others that are fast file
formated.
…Dave
Dave,
My first Partition which is used for the WorkBench System Stuff is about 5
Meg which is currently about 50% full. However, it does use the Fast File
System like the other partitions. The MicroB. HardFrame allows it to use
FFS, that is, if you have a HardFrame. Don't forget, you'll want the extra
room for any additional libraries and also commands that you want to add to
the c: Dir. My Libraries, Handlers, etc. size has more than doubled since
I first got a Hard Drive. Alot of prgrams these days come with their own
libraries that get added to the system.
Kerry
Kerry,
I've got the Hardframe and I'll use the info you are giving me.
…Dave
Another thing about partitioning that I learned from experience. If you
make multiple partitions it's better to reserve one as a scratch partition
that's at least as big as the biggest partition on the drive. This way if
one of the partitions starts giving you problems or goes bad you can run
disksalv on it (after backing it up) and send the files to this scratch
partition to recover them easier. Just a thought. I'm No genius, just
repair several types of big 300MB Hard drives all the time for a living.

Kerry
Kerry,
Good idea! I'll incorporate that into my final set up. Getting close now.
