On Windows 7 RTM, moving a file over an existing file can cause a
ERROR_FILE_CORRUPT "The file or directory is corrupted and unreadable." error
where older Windows version used to give an access denied error.
This error is indirectly caused by using specific other applications
at the same time. Most likely
* Windows Search (indexer)
* Virus scanners.
After this issue is triggered you get an error popup on your start bar
indicating that a disk corruption was detected and that you should check
your disk for further errors.
Last but not least Windows schedules a full "CHKDSK /F" for the next reboot.
(Luckily it never finds errors after experiencing just this issue)
This is NOT a Subversion issue, but an issue in Windows 7. We can't work around
this issue inside subversion as we can never resolve the side effects mentioned
above.
(And handling catastrophic disk failures as 'access denied' will make you loose
more data if there is really something with your disk)
In all user cases reported on the AnkhSVN support list, running svn cleanup
fixed everything. (No data was lost).
