because the _disk_ sda doesn't house a filesystem, the _partiton_
sda1 does.  You need to find out where that partition started and ended
on the disk sda.  My thought was maybe windows would format it the same
way twice, in which case you can format and then get the partitioning
information out of the device, reformat, write the part of /tmp/r1 that
coincides with the partition, cross fingers, and try mounting.
