[Bug 1598868] Re: growisofs bug

Regrettably it does not tell the additional info numbers ASC and ASCQ.
But SK=3 means that the drive cannot write to the medium because of
unexpected problems. I.e. not because the DVD would not be writable by
its type and state.

"220h" means that the drive raised protest after growisofs sent it the
first 544 blocks = 1,114,112 bytes. This is well within the size of the
drive buffer. So one may assume that the drive was not able to write
any data with sufficient quality.

If other burn programs (e.g. my libburn) yield better success, then this
would either be because mere luck, or because a different write method was
used. Write methods depend on the DVD type, e.g. DVD-R offers DAO and 
Incremental, DVD+R offers writing with or without track reservation.
The growisofs run did not require DAO. But it is not obvious whether DVD-R
or DVD+R was in use.

Whatever, a first try of remedy would be to buy some new DVD media of
the other type as the one used before. E.g. DVD-R if your failure was with
DVD+R. If this helps, try newly bought DVD of the type and manufacturer
that failed before.

If not the failing old DVD media turn out to be just bad while all newly
bought DVD work fine, then it is time to consider replacing the burner drive.

Have a nice day :)
