#31 Hardware/Media/IO/sendcmd error

[Mark K.]

Hi,

I get random errors burning DVDs. Maybe one out of every 10th try.
When I try again it works. Not sure how to even start to resolve this:

Are those bad media? Bad drive? OS incompatibilities? Bug?

Correction, this was a BD-R, not a DVD.

[Mark K.]

Same problem again.

12 times it worked now since the last problem in May with the same kinds of blank disks. And on the 13th try today I am getting

[...]

Then after restarting cdrecord it magically starts working again with the same drive and same Blu-Ray disk.

Any ideas?

Oh, I just found the bad news about the author, never mind. RIP
