tsvn and the mbr

Just an update and my analysis.

1) svn does generate a lot of disk access (and also for large
repositories : thousands of small files are on disk making the Master
File Table much bigger than it was)
2) a power cut occurs during high disk traffic
3) may imply that the Master File Table gets messed up (The disk
partitions are still visible but appear empty)
4) First got most files back using 'getdataback'
(http://www.runtime.org/gdb.htm), which was good.
5) Tried, fixboot fixmbr of Windows Recovery Console without success
(logical they don't touch the mft).
6) tried various other tools from web : failed.
7) reformatted and copied back files from 'getdataback'.

So svn does not seem at fault but because of its nature and the nature
of large repositories it makes the mft more vulnerable should you be
unlucky to experience a power cut during heavy disk updates (i.e. when
the mft is being written to)

regards,
chris
