Bug#594753: Do we know which, and what proportion of drives and if so how do we know this?

[Simon Waters]

Old DELL shipped DVD/CD drive has this issue:

description: DVD reader
product: RW/DVD GCC-4480B
vendor: HL-DT-ST

This could result in loss of user data if the user naively accepts that
writing without "obvious" errors means it worked, should the default
behaviour not also verify data written to media since the software is
unreliable.
