I'd like to use disk drive on pegasos 2, so I downloaded trackdisk.lha from aminet, but it does not work at least under mos 3.15
I recompiled also sources with very latest sdk, same issue floppy isn't recognized.

Any way to resolve? ..I already know amiga floppies can't be used, due hardware limitations, but this is not a issue for me.

Sorry, no solution for that issue. But maybe an USB Floppy drive could be useful.

What fdd cable? twist?
How is the ds0 or ds1 jumper set?
What happens when you run a mountlist?
Fdd does not have diskette autodetection.
Did you read the documentation?

Yes.
Fdd usb is working fine.

Sonic made trackdisk.device for Pegasos

https://sourceforge.net/projects/unmorphos/files/Pegasos%20trackdisk.device/trackdisk.device%2041.3/

and you can also use LS120. Zips, Syquests also work (with SCSI controller, i didnt check with ide).

Yeah I used trackdisk.device from Sonic and downloaded also fat95 from aminet to use fat filesystem.

here is my mountlist as suggested by Sonic in trackdisk readme

/* MS0: fat95 PC file system for floppy #0 */
/* $VER: fat95 file system 3.06 (08-Aug-2002) by Torsten Jager */

FileSystem = l:fat95
Device = trackdisk.device
Unit = 0 /* change drive number here */
Flags = 0
LowCyl = 0
HighCyl = 79
Surfaces = 2 /* bootblock values have priority over these */
BlocksPerTrack = 18
Buffers = 20
BufMemType = 1
BootPri = 0
Stacksize = 4096
Priority = 5
GlobVec = -1
DosType = 0x46415400

MS0; device is not mounted, on startup mos ask me to assign/mount the device.

@Flash
At least you can use the built-in FAT...

How can I do? Floppies are fat so it’s ok for me

I found also an old thread on morphzone, same results..
Is there peg2 owner to have internal floppy working?

Yes, floppy works on my Peg2 (MOS 3.15) fine!
You have to use trackdisk.device V41.4 (built 19.8.2010) and mountlist above. If change floppy you need diskchange-command for Ambient to recognize. Only high-density-floppies supported!
If you dont find trackdisk.device 41.4 send me your mail via PM.

Thanks a lot, you have pm.
It could be very useful spread solution on morphzone if any other is or will be interested

I have this in backup - it works for me fine years ago: trackdisk.device 41.3(2007-20-08)
Unfortunatelly I don't know with what MOS version I used it.

Because I stoped to use FDs many years ago, I remove FD drive from case when I upgraded my Pegasos 2.

It seems do not work, amigaharry2 have written about a newer version 41.4 of trackdisk.device built 19/8/2010

You have PM!
Unfortunately I don't know where to download that newer device - can only send it directly to anyone interessted.....

Thank you very much, I received you mail and tested new trackdisk on my peg2.
Sadly it does not work!
Really I don't know why, it should have been an easy task and I followed all steps, checked all 10 times.
On startup MS0: device seems to be mounted but when I try to access it I got a requester to assign, mount, retry, etc..

I noticed on mountlist filesystem is set to "FileSystem = l:fat95", do I have to download fat95 archive from Aminet?

Under Linux at least floppy led goes on and starts reading tracks, soon later system crashes and I have to reset machine via hardware reset.

My Peg2 board is latest rev b5 with 2gb ram - MOS 3.15
Do I have to check something in smartfirmware?

Yes you have to download FAT-filesystem. I thought you have that installed allready.....
There is nothing to do in OF.

For testing: Take a new floppy and try to format it.

>> do I have to download fat95 archive from Aminet?

> Yes you have to download FAT-filesystem.

Isn't the FAT handler MorphOS comes with to be preferred, or doesn't that work with trackdisk.device?

Fat95 from aminet does not work, at least for me.
It’s all 68k asm code native os3 binary, I don’t know if it’s compatible with mos.
Any others repo to download fat handler for mos.?
Does mos have some internal handler I can use for fat filesystem?

68K-versions works well on MorphOS (MOS has a built-in run-time 68K-compiler). There seems to be another issue.
I use (68K) fat95 3.11 form 10.08.2003 by Thorsten Jager.

Check following:

After booting system insert a disk. Then type in a shell

diskchange MS0: (notice: MS0 not MSO!!)

Can you see now flashing the busy-LED from the floppydrive? If yes,device works and MS0: is mounted.

If not:

What happens when starting MS0-mountlist manually by typing in a shell mount DEVS:Dosdrivers/MS0 ? If message MS0: Allready mounted appears, then mountlist works. If not, you should look for propper setting tooltypes in MS0-icon! Have you set anything to MS0-icon, as I wrote you in PM (as shown in picture)?

Actually, the MorphOS provided FAT Filesystem should work with floppies as well, even though it uses FAT12 there afair. This sounds like a bug in the MorphOS FAT FS, there should be no need to use another filesystem for FAT formatted floppy discs.

MorphOS fat Filesystem works with USB Floppy drive for sure.

Ok thanks LL four your interest.
what's the name of MOS filesystem?
What I have to replace in following mountlist line? FileSystem = l:fat95

..Why me and Amigaharry2 got different results?

For old MSDOS floppydisks you may/can only use l:fat95 (as I do), or MOS-built-in FATFileSystem (which I never tried till yet). If you wan't use it, mountlist should be changed to:

Filesystem=FAT (hope that's the right name.....)
and
DosType=0x4d534400

Nevertheless I have to ask: Do you really use a HD-floppydisk? DD-floppies are not supported by trackdisk.device!
Have you done,what I wrote above? Did you see the buzzy-LED, when executing Diskchange-command?

Tried all you suggestions.
I have only HD floppy on diskchange ms0: drive led never light on.
As last hope I want replace floppy drive with another spare one (samsung), I want to change also floppy cable.
Maybe tomorrow I'll be able to report you results.
Thanks to all involved.

I used to use Catweasel Mk.3 for accessing floppies of all kinds - FAT, FFS, HD, DD, etc. (Not DiskSpare unfortunately - never could get that to work. Hardware-banging driver.)

It worked quite well, except that there was something up with either OpenPCI, the driver, or the FFS2 filesystem that locked the machine every so often on mount, which meant I couldn't put the mount file in DEVS:.

I never even tried to connect up the internal floppy at the time. I was told it just wasn't supported because time was best spent on something else. And to be honest, it was true. I never got much use out of the CW3 except to load old floppies which I'm sure these days I can find on the internet in DMS or ADF.
