I have a 64GB USB stick that works correctly in Windows and Linux but not
in FreeBSD. The problem is during the write.
In FreeBSD I have tested the stick with the command:
# dd if=/dev/zero of=/dev/daX bs=1m
and, after some time, I received these errors in i386 and amd64:
Hi,
Hi Hans,
thank you for your answer.
Are you sure the disk is of the size advertised?
In Linux I obtain:
$ uname -a

$ sudo dd if=/dev/zero of=/dev/sdf obs=1M seek=8100

Hi,
What does "dmesg" say after these errors? Maybe you have a bad sector?
Did you try to add "conv=noerror" to dd ?
Did you try "bs=65536" or "bs=512" ?
