Syquest Removable Media

[GoodLook]

I have a Syquest Removable HD connected to my amiga.
Some of the HD's are working Fine.
With some of them I receive
"Error:Invalid Rigid Disk Block"

I gess I formatted some of them as DOS. But this it is so long ago... I do not remember how to open DOS formatted HD's on my Amiga.

I have also icons DISK:NDOS

HELP  :-?

I have here SCSImanager where a mount the new cartridge.
after I unmounted and mounted the new device then what to do ?

I also have HArd Drive Preparation
where I can change the Syqeust to:
Syquest SQ5110 ot SQ555 but as far as I remember this is only to chenge to 44mb or 88mb.

On the other hand I have CrossDos and Crossmac on my PC.
but I do not have a scsi in my PC.

This program fat95 can it do anything wrong to my disks ?
