All data goes to sapdata1 during installation

Question

I was about to install IDES ECC6.0 in default, but it turned out to be an error saying like out of space in sapdata1 directory. Even if we allocate the data into several directories, all the data goes to sapdata1 direcotry. 
does anyone know the workaround?
i have been successfully installing the same version but not IDES one with the
same procedure.  btw, we have 300gb space.
any comments would be highly appreciated.
regards,
yu

HI,
Boot from your 10.5 disk while holding down the C key and check the startup disk for errors.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
Check available disk space.
Control or right click the MacintoshHD icon on your Desktop. Click "Get Info". Under the General tab you will see Capacity and Available. Make sure there is at least 10% available disk space, 15% is better.
If you cannot boot from your install disk, try booting in Safe Mode
What is Safe Mode
