I am using Windows, and the GUI, and v3.00 of the software.
I did see, but the links on the thread are broken, atleast the releases.softpress.org reports an error in chrome stating that an IP address could not be found.
Let's presume this is a problem with the disk spinning freely. Does anyone have advice on how to improve the diskette?
I can puff some compressed air into it. I think that would not cause harm, but I am no expert.
FWIW, these were Xerox media, written in 1988, stored indoors until now and never read.
This is the first time they are spinning ever.
There are a number of different possibilities:
1: There is "gunk" on the cookie surface, increasing friction between the cookie and the head. I encounter this all the time, and if not immediately addressed it may rip up the disk surface. Visually inspect the disk surface. Usually a careful cleaning with a q-tip and water, or if no shedding alcohol, will fix this. Also, run a disk cleaner through your drive to make sure the head is not gunked.
2: The disk jacket is warped, or the jacket edges are crushed. Happens with 5.25" disks that have been stored underneath heavy books. If the physical disk is not important, the best way to address this is to carefully remove the cookie from the jacket and put it in a known good donor jacket. If the physical disk is important, you can try carefully bending/pulling the jacket back in shape. (Although I don't recommend it, very judicious use of a hair dryer can be used to intentionally warp the jacket so it puts less pressure on the cookie).
3: There is a problem with your drive. Using a known good disk, sanity check that it is spinning at 300RPM plus or minus only little bit. (360RPM for 1.2mb, 8" drives, or Mode 3 3.5" drives). Don't use a drive with a belt-driven spindle motor, that is just asking for problems. Make sure the spindle mechanisms are clean and engaging the disk properly. (I have a couple of Teac 3.5" drives that don't like to engage properly when they get dusty).
