thanks.
that's a convenient tool.

however, it keeps producing:

$ bonnie -d /media/tmp/
Writing a byte at a time...done
Writing intelligently...Can't write block.: No such file or directory
Can't write block 478518.
$ bonnie -d /media/tmp/
Writing a byte at a time...done
Writing intelligently...Can't write block.: No space left on device
Can't write block 474393.

i checked the default parameters. nothing seems wrong.
i was benchmarking a kingston 4GB microSD card, connected with a usb adapter.

any help will be appreciated.
