It does this automatically before writing begins. BD-R formatting does not last long. Other than with BD-RE the drive cannot write and checkread all blocks just for a test. growisofs_mmc.cpp emits a message in function bd_r_format() fprintf (stderr,"%s: pre-formatting blank BD-R for %.1fGB...\n", ioctl_device,(f[0]<<24|f[1]<<16|f[2]<<8|f[3])*2048.0/1e9); This undocumented growisofs option can suppress BD-R formatting: -use-the-force-luke=spare=none > Have to wait for payday to buy another (which is sad). And i am too thrifty. Shame on me. My only excuse is the usual reason that i am an unpaid volunteer. (This saves me from implementing UDF, too.) I just had a look at the market in germany: My usual hardware provider wants 37.85 EUR for 5 pieces Verbatim 100 GB, or 25.63 EUR for 5 x 50 GB. But there is some hope: 25 x 50 GB no-name for 44.80. 50 x 25 GB single-layer Verbatim are at sale for 26.94. So double-layer is now just twice as expensive per GB. Ridiculous: 5 x 100 GB Verbatim M-Disc for 71.70. Have a nice day :) Thomas _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
