[comp.sys.cbm] 1541 Disk Drive Help

gandalf@spock.UUCP (Mark Halstead) (03/02/90)

Help! My 1541 thinks there is a permanent write protect tab!  I can read
files fine, but I cannot write anything to any disks, it gives me a 'write
protect' error.  Does anyone know how to fix this?  I think it is a software
problem turned hardware problem.  I recently got the newest version of Kermit
from a friend, who neglected to inform me that the 'kermit-boot' file was
for C128's.  So I loaded it and ran it.  It gave a 'no block' error. THEN
I listed it and found it was for C128.  Ever since that point I have been
unable to write with my disk drive. PLEASE HELP!

thanx in advance.

The likely reason that your 1541 can't write to a disk is because the the write protect sensor is covered with grunge. Use a good disk cleaner.

     Open up the 1541 and clean the little LED that senses the write-protect
notch (clean with alcohol or diskette cleaner).  This is the most obvious
hardware problem (also check the connecting wires for shorts).  
     There also could be a problem with the drive ROMs, which someone with
more expertise might be able to check.  But check the obvious hardware problems
first.

     A disk cleaner doesn't go near the write protect notch.  The
cleaning must be done manually.
