Most every plug-in uses some kind of metadata and evms seldom makes it up.
The dos plug-in uses MBR and EBR sectors for creating dos partitions.  It
will also maintain os/2 drivelink-address-tables (dlats) if they are found.
It didn't create any new metadata because it would not be compatible with
any other dos partitioning utility like fdisk.  In short ... the MBR is LBA
0 and OS/2 dlats are the last sector of every MBR and EBR track.  An
extended partition is specified in the MBR partition table and the very
first sector of the extended partition (cyl alligned) will have an EBR that
anchors the EBR chain ... and so forth.

i will install my testdisks and check it out as soon as possible.
