I'm having a LOT of trouble with reading disks in CP/M mode on the C128.  A
friend of mine gave me a disk which was formatted Kaypro II on a dedicated
CP/M machine and I assumed I could read it.  When I try to read it, it (CP/M)
states that the disk is Kaypro IV and then gives me an I/O error.  I have even
tried formatting Kaypro II with my 1571 but it does the same thing.  In fact,
ANY format that I try to read gives me an error (I have tried EPSON QX10,
Osborne DD,Kaypro II and IV, and IBM - all of which seemed to format fine - I
used the parameters given in a previous article for these formats.).  However,
I HAVE been able to read an IBM disk formatted on an IBM PC, although I
imagine the dir setup is different - the dir listing was blank but I didn't get
any errors.

I was also wondering if the 1571 also sets up the directory after formatting
using the burst format MFM command from the manual, and if not, could this be
the cause of the I/O error (ie. all sectors empty)?

Incidentally, I think the I/O error from the disk my friend gave me may have
been caused by the fact that one side was Kaypro II and the other side was some
other format.

Any help would be M U C H appreciated. After all, what good is CP/M if you can't
use it?
