Syquest PC formatted
« on: December 25, 2018, 12:36:41 AM »
A friend gave me his old Syquest SCSI drive and a bunch of old disks, since he have no computer with scsi anymore, and I easily got it up and running on my old A500/GVP HD8+ setup

But, how do I read these old disks of his, he wants to see what's on them before I format them for Amiga use. It's been so long since I did something like this so I have completely forgotten how to do this.

Only thing I can think of is needing Crossdos 7 but where can I get that these days?

You don’t need CrossDos, Fat95 should work and it runs on kick/WB 1.3. It can be found on Aminet.

You might have to write a custom mount list to get it to work but there are tools to help you with that on Aminet. Start by reading the Fat95 manual.

This tool might be useful, if I understand it correctly it can read the MBR from a DOS disk and create a mount list automatically.

Ah, thanks. I'll have a look at that.

No, I can't make it work. I don't know what I'm doing wrong. I have the syquest configured as #2, HDTOOLBOX can see that the drive is there but that's as far as I get. I have also put a terminator at the passthrough on the syquest.

Even got hold of CrossDOS 7 Gold (Yeah, I'd love to pay for it if I only knew to where.) but that didn't make any difference, I still cant make the OS find the syquest disks.

Fat95 or giggledisk isn't all that clear as to how to go about making a syquest disk readable. I can't figure it out. I'm sure I'm doing something wrong but since I have no clue as to what I really don't know.

I guess giggledisk works fine if you know how to configure it but I can't find anything in the readme that tells me how to make it read the syquest so I'm completely lost.

Just do add. All the disks I have for the syquest are 88MB so I only need one mountlist for all of them.

You should read the documentation of FAT95. It describes step by step how to build a proper mount file.

This one should work:

Code: [Select]
Device = gvpscsi.device
Unit = 2
Flags = 0
BufMemType = 1
MaxTransfer = 0x20000
Mask = 0xfffffffe
Filesystem = l:fat95
StackSize = 4096
GlobVec = -1
Buffers = 200
Control = "+s -d -D +l"
Activate = 1
LowCyl = 0
BlockSize = 512
HighCyl = 1
BlocksPerTrack = 1
Surfaces = 1
DosType = 0x46415401

Problem is I had no clue as to what numbers would be valid for a disk. I did read but didn't quite figure it out anyway.

Thanks for the help though, much appreciated.

Fortunately FAT95 and I think also CrossDOS have the capability to read the PC partition table and adjust the numbers accordingly.

Without that feature you would have to enter proper values for LowCyl, HighCyl, BlocksPerTrack and Surfaces.

I can't seem to get it to work.

Using the mountlist from the post above doesn't help I'm afraid.

I've tried with Crossdos 7 and using the ConfigDisk program it detects the disk and the partition on it. Just don't know where to go from there because moving on it says the partition will be deleted if I continue. Since I don't have the manual I can't read on how to go on about this.

THough, it might of course be because something isn't right, the computer is rather unstable so I might have to address these issues first. Strange that I can see the partition though if that's the case.

You would get better help if you would present some of your test results here. You alwys only say "can't get it to work" or "don't know how to proceed", but you never give any details, numbers, messages, screenshots, whatever you got.

You're right.

Though, I've figured out a part of the problem. Haven't really had the time to try out more since I've been working hard with my 4000 instead. Will note what messages I get when I try again.

But I would love to know how to use Crossdos 7.04 to make the mountlist since I don't have the manual and the readme isn't very helpful, it just says look in the manual on how to.

So. Using the CrossDos program "ConfigDisk", managed to figure out how to interpret what it said, to create a mountlist. It sees the disk and a single partition. It says it's an "MS-DOS Floppy"

I've tried with fat95 and with CrossDosfilesystem and managed to mount something with the correct size but it's all empty, nothing on it. Found another filesystem on Aminet, FATFileSystem, and with that I managed to mount something with the correct size but the result was kind of opposite. 100% full but couldn't see any files here either.

I've tried a few different settings for DosType, stack, buffer but the results are either the same or nothing at all.

My friend knows there are files on the disks, they aren't empty. I really don't know where to go from here. Yes, I know it isn't all that much information but I'm not getting any error messages. Maybe it's just not possible to read them at all. I haven't tried CrossMac though, but since ConfigDisk says "MS-DOS FLoppy" I doubt they're mac formtted, or?

All but one are 88MB, the last one is 200MB.
