Actually i had SQL server 2005 in window 2008.

First, detached the Database.

Second, Uninstalled sql 2005 and installed sql 2008.

third, Attached the Database.

I could attach the first mdf file....

Yes G and H are local drives.

We have reported the problem to the windows team. They are working on it.

I will keep updated when i get any updates...

I m receiving below error when I am trying to copy the backup file from H:\Full to G:\.

Error: Invalid MS Dos function.

Thanks for looking into the problem.

the answer for the question is:

Yes. It has admin access.

Thanks.

Yes .you are right.

I would keep the instance directory in C:\ Drive and use the 2 other drive assigned for data. am I right?
