Hard Drive High Frequency Load / Unload Cycle

[DigitalPig]

Hi~ Recently I discovered a strange sound in my IBM Thinkpad Z60m
laptop. Then I check my hard-drive with smartctl. It seems that my HD
has a park/unpark movement every 30s. When I issue:
,----
| hdparm -B 255 /dev/sda
`---- 

Then the sound disappeared. I am wondering if there is any bug-fix
for this bug? Any patches of kernel or acpi modules for that? Since it
seems a bug for a long time. Thanks
