#65 errors on mounting and formatting

[Anonymous]

With a LG H58N I get error on mounting:

Can't read superblock

kernel log shows:

kernel: pktcdvd: write speed 0kB/s
kernel: pktcdvd: bb 00 00 00 00 00 00 00 00 00 00 00 - sense 00.00.00 (No sense)
kernel: pktcdvd: pktcdvd0 couldn't set write speed

I can mount and write to it without packetwriting.

formatting with mkudffs:
trying to change type of multiple extents
