I don't think, he does say that.
Of course, interrupting a firmware programming process has a high probability of killing the device. But such is not normal software operation, isn't it?
But back to your initial question:
Could be also a matter of the blank media you are using. Or a dirty lens system.
My question is:
I may damage my cd writer flashing the wrong firmware ?
Yes. But the TSST firmware update mechanism is protected against flashing a firmware version that does not match the drive.
And, a virus could be damage my cd writer making a fake firmware flashing with the aim of damage my writer ?
What for? Malware is used by criminals who want to make money. They are not interested in damaging their victims' computers.
In theory, a skilled programmer can build such a TSST drive killer. But such would be only successful if you permit its execution.
Those question come up from the following facts:
I have a tsstcorp cd writer on my macbook, but it does not work.
I bought a new i7 with 16 giga ram and a working tsstcorp and after some weeks it has stopped to work.
I substitute it with a new one that it worked but after few weeks it has stop to work.
Hardware still covered by warranty? Then contact the vendor.
So it's very strange.. I suspect to have a virus that damage my cd writer.
So it is theoretically possible ?
Theoretically possible but in real life unlikely.
There had been some malware around that accidentially damaged the ability of Windows software to access optical drives. Nothing that couldn't have been fixed by flattening and rebuilding the OS.
There are other reasons why your drives are malfunctioning.
