Don't understand what you mean by this, can you please explain???

Below is what I found about "Capacity Clipping" etc on the Hitachi/IBM
website.

Feature Tool (v2.01)
This is a DOS-bootable tool for changing various ATA features. The
Feature Tool allows you to control some of the features of our Deskstar
and Travelstar high performance ATA hard disk drives and supports 48-bit
addressing, so it will work with the new large capacity drives.

This version adds support for our latest drives. Changes include:

Enhancement of SATA support
Enhancement of Capacity Clip Function

The Feature Tool allows you to:
Enable or disable the read-ahead or write cache.
Change the drive Automatic Acoustic Management settings to the:
Lowest acoustic emanation setting (Quiet Seek Mode), or
Maximum performance level (Normal Seek Mode).

Change the predefined capacity of the drive.
This option can be used in situations where there is a BIOS limitation
and the drive is not recognized.
See the Users Guide for specific details.

Switch the Ultra DMA mode
Change Advanced Power Mode - allows you to change between the lowest
power consumption and the highest power consumption (maximum performance
level).
Show Drive Temperature - shows the current drive temperature in Celsius
and Fahrenheit.
Configure SATA interface - adjust maximum speed and enable/disable
Spread Spectrum Clocking.
