Now I am lost too.  You say"went to format /d3 and got error msg "221." The
error translates as MODULE NOT FOUND.  If you were to do an MDIR I suspect that
you will not find a module by the name od D3.  This means that you do not have
a descriptor for a drive called /d3. (normall

- ooh - butcher job of editing. (normally /d3 is the fourth drive  ie /d0 /d1
/d2 /d3 and unless you want to become a hardware guru stsy away from trying to
have more than 3 double dided drives ) Remember - you can only format drives
for which the computer has a descriptor in your system right now you have
probably got /d0 /d1 and /dd yes?  /dd is usually an alter ego for /d0 but can
be the hard disk or anything else. what do the descriptors you have contain? 
they must correspond to the physical hardware - ie if /d0 is single sided then
the descriptor has to say so if /d1 is double sided likewise.  Please remember
- double sided OS9 disks are NOT like under RSDOS - there is ONLY ONE DISK.  ie
/d1 being double sided 40 tracks will have 1440 sectors (decimal) arranged
alternately fron one side to the other on the diskette.  The drive can read and
write and format single sided diskettes (to format you first use dmode)9 to
read or write just stuff it in. Does this make sense to you? re error and help
- in the /d0 SYS directory do you have the files ERRMSG and HELPMSG? do you
have the commands error and help in your commands directory?  What happens when
you type error 221 ?
