Manual 3-17: Upward disk compatibility Single sided disks that have been formatted with rev 2.1 software will load on all rev 3.0 units, whether they have been expanded or not. Loading and saving a rev 2.1 disk on a rev 3.0 unit does not change that disk into a rev 3.0 disk. (this is what enables rev 3.0 to be used as a retro fit on an expanded unit) Downward disk compatibility As mentioned above you can load a rev 3.0 disk into a rev 2.1 unit if its A or B side are 128 blocks or less, because in this case only the first side of the disk is used. If a rev 3.0 disk using more than 128 blocks is loaded into a 3.0 system with standard memory, any sample stored on the second disk side will not be loaded, but no error will be indicated. NOTE: Loading the rev 3.0 disk into a rev 2.1 unit will produce an "if" (incorrect format) error. Simply override this error by pressing execute. HOWEVER results are not guaranteed with a two-sided disk if it has data on both sides, or when loading one sample. To prevent the "if" error from occurring each time you load a rev 3.0 disk on a 2.1 system, save the data to a disk which has been formatted on a 2.1 system. You cannot save or compare from a rev 2.1 unit to a rev 3.0 disk. Attempting to do so will cause an "if" error, which cannot be ignored. This is done to prevent destroying important system data which is on a rev 3.0 disk. Determine disk type: If the rev of the disk is unknown, try loading it into a rev 2.1 unit. If an "if" appears, than the disk is a rev 3.0. Otherwise its 2.1. If you have a 4.3 or whatever I guess the same still applies?

If I format a floppy with the first, the second says iF (incorrect format?) when I try to save something on it. But if I save a disk in the first, the second can read it without problems. Then I noticed that there are some disks that are read with no problems with the new drive but not with the old one. And other disks behave the opposite!

I only have 2 original Sequential disks (1986, for the 512K version: #875-01EX REV A and #875-02EX REV A, unfortunately they don't work!).

Today I got an used 2002 and unfortunately I have problems with the floppy drive. But istead of getting the "nD" message I get again and again a bliking "Lh" message. If I i.e. choose to format a floppy I put into the drive, the drive gives a spin, the red light lights for 1 second or so and I get that "Lh" on the screen. > > > > >> > > > > >> Any idea? > > > > >> > > > > >> Thank you! > > > > >> > > > > >> Edo > > > > >> > > > > >> > > > > >> > > > > >> --- In prophet2000@ yahoogroups. com, Rob Miller <dpc318@> wrote: > > > > >>> Well, I replaced the 7406 buffer chip between the floppy controller and > > > > >>> the drive, and while the individual logic is better on the chip, it > > > > >>> did not resolve my "nD" issue. > > > > >>> > > > > >>> My drive seems to be spinning all the time while a disk is in it, > > > > >>> with the red LED on.
