Yes, there is. (And I already reported it at least on the Debian bug
tracker, see links in the initial message.)

f3 reports overwritten sectors, i.e. it looks like the pseudo-random
test pattern is written to wrong position. These corruptions occur in
clusters whose size is an integer multiple of 2^17 bytes in most cases
(about 80%) and 2^15 in all cases.

The frequency of these corruptions is roughly 1 cluster per 50 GB written.

Can others confirm this or do they observe a different characteristic?

Regards Stefan
