THE OUTPUT YOU RECEIVE
HOW TO HANDLE ERRORS
EXAMPLE
4-4
GC34-0070
This utility produces an initialized diskette in basic exchange format (one that is
interchangeable with other systems). If any defective cylinders are encountered, the
utility issues this message, one for each defective cylinder, in the following form:
IlU140IDEFECTIVE
CYLINDER cch
I
where cch is the number of the defective cylinder and h is the head number. The utility
prints this message to indicate that it has finished:
RIOOlI DISKETTE INITIALIZATION
COMPLETED
If the utility encounters a recoverable error, it prints an error message and reissues the
prompt. Recoverable errors are:
• Device address not valid
• Device at specified device address not diskette device
• Invalid VOLID/header name
• Cylinder 0 defective
• Unable to initialize because there are too many defective cylinders (two cylinders is
the maximum)
If the utility encounters an unrecoverable I/O error, it abnormally terminates. To
reinvoke the initialization utility, you must relPL.
The following example shows a typical initialization, where the diskette device address is
002, the user's new VOLID is VOLOOI, and the old VOLID is VOL999.
