No, but it is also NOT known to have 100% bug-free firmware.

My own system has a 5GB MAXTOR drive. Very nice, very fast,
but if Linux chucks too much data too quickly at it (something
that Windows is unable to achieve), then the drive reports an
error just like the one you are seeing.

In both of our cases, the Linux IDE driver correctly just retries
the operation. No harm done.
