Disk Write (5) Error; Ce Mode - IBM 3741 Data Station Reference Manual

If a write error does occur after pressing record advance,
the sector is probablY defective. Reset the write error and
perform a delete record operation. If the delete record
operation is successful (no write error), add the record to
the end of the data set.
If the delete record operation is not successful, or if the
record cannot be added to the end of the data set, the copy
operation can be used to copy the surrounding data and
then manually key in the record. Be sure to write the track
and sector address on the external label of the diskette on
which the error occurred. The diskette should be initialized.
Disk Write (5) Error
A write error occurs when a record is not written on disk
correctly. When a write error persists, perform a delete
record operation. If the delete record operation is success-
ful (no write error), add the record to the end of the data
set.
If the delete record operation is not successful, or if the
record cannot be added to the end of the data set, the
copy operation can be used to copy the surrounding data
and then manually key in the record. Be sure to write the
track and sector address on the external label of the diskette
on which the error occurred. The diskette should be
initialized.

CE MODE
CE mode is used by the customer engineer when testing or
troubleshooting the equipment. This manual does not
describe how this mode works or how it is used but merely
points out how it is entered and how to get out of the mode.
Pressing FUNCT SEL lower, NUM shift, and C puts the
machine in the CE mode. The status line displays CER in
positions 38, 39 and 40.
Pressing RESET several times returns the machine to the
index mode with the label from sector 08 displayed. After
the machine leaves CE mode, the program buffers of the
3741 may be changed and therefore should be checked.
The CE mode may modify the EOD field and the verify
indicator field of the data set label for the data set being
used when CE mode was selected. Therefore, those fields
should be checked and corrected if in error.
