Did it have a positive effect on the Solaris machine ? > On solaris I used this command for burning > # growisofs -Z /dev/rdsk/c3t0d0s0=image.iso According to Andy's text i assume that the media was formatted automatically and thus would at most be written at half its nominal speed. 4.5 MiB/second. But the reported performance was less than one third of that half. Still very mysterious. > To use SRM with no spares on the CentOS box > would I try a command line similar to this? > # growisofs -Z /dev/scd0=image.iso \ > -use-the-force-luke=spare:none -speed=2 That's what i read from the text. (I have my own burn programs to test. Thus i use them at any occasion i have with BD media. One year of BD burning strengthened my opinion that at least my drive and my media work well with full nominal 2x speed.) I would omit the -speed option and let growisofs negotiate that with the drive. Afaik -speed is rather intended to slow down poor media.
