dear gail shaw

thanks again

but it was my mistake and i m extremely sorry that i told u that its only one physical drive ,but actualy there are 3 physical drives of 36 gb each. but we get the 80gb only for use rest gets occupied with raid controller 5.

E drive is with practice databses and one full backup file everyday come on e drive in evening and gets zipped.

now my tempdb is on c drive but both log file i.e ldf file and data file i.e mdf files are on d drive.

and there is no other application except sql on this server.

please kindly suggest me the next!!!!
