6 The problem is that the CLOSE TRACK/SESSION command is appropriate
7 for the end of burning BD-R, only if it is unformatted or if it is
8 formatted to SRM without Pseudo Overwrite.
9
10 As soon as it is formatted to Pseudo Overwrite, the command is
11 inappropriate, which the burner indicates by the ILLEGAL REQUEST
12 error code (which one would see if K3b would not swallow it).
13
14 The bug of growisofs is that it formats the BD-R to Pseudo Overwrite
15 but omits to memorize this new state.
16 If the BD-R is already formatted to Pseudo Overwrite when growisofs
17 inspects it, then its state gets memorized and the inappropriate
18 SCSI command is not issued.
19
20 My patch proposal just sets the memorizing Pseudo Overwrite flag
21 after the medium has been formatted. So growisofs treats it the
22 same as if it had already been formatted when growisofs first
23 inspected it.
24 This avoids the error.
