To keep the number of driveletters to a minimum, have
the same directory structure on the instances and do
something with disks and performance I tried this:
MSSQL$I1\Data
\Data1 <- mount point
\Tlog
\Backup
\Backup1 <- mount point
MSSQL$I2\Data
\Data1 <- mount point
\Tlog
\Backup
\Backup1
MSSQL$I3\Data
\Data1
\Tlog
\Backup
\Backup1
And ran into the SQL Setup does not support mount points
bug or feature. So I added driveletter to the mounted disk.
I am still thinking off using the mount points next to the drive
letters. Are the any other issues or disadvantages I should be
aware off?

Hi
Have you looked at http://support.microsoft.com/kb/819546/en-us "SQL Server
2000 support for mounted volumes"?
On non-clustered systems, the base drive needs a drive letter.
