Hi, the answer is no. The disk space you configure for your database is never returned to OS. If you specify raw devices, the devices are to be used by SAPDB only. If you use normal files, the files are preformatted (filled with zeros) to make sure disk space is as contiguous as possible. This takes some time during first time initialization... But it is done to minimize seek times. SAPDB does not use the underlaying file system, but has its own file system implemented which is database page oriented...
