This is supposed to make your hard disk access faster. It works very well for me on both my 7200 Ultra ATA 66 drive at home and my sh!tty 5400 Ultra Crapper at work.

Configure the Contiguous File Allocation Size (Windows 9x and NT)
This setting optimizes the contiguous file allocation size for the file system. This is especially useful for disk intensive applications.

Open your registry and find the key below.

Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem]
Value Name: ContigFileAllocSize
Data Type: REG_DWORD
Data: 200 (hex) or 512 (decimal)

Create a new DWORD value named 'ContigFileAllocSize', set the value to equal '200' (in hex).

Close the registry and restart the computer for the change to take affect.
