Such sound is NEVER heard when shutting down WinXP. I am afraid that this causes excessive stress to a modern HDD. The specification for Travelstar 5K500.B at http://www.hitachigst.com/tech/techlib.nsf/techdocs/013B2CE7D7CBD07586257609007A40A3/$file/TS5K500.B_OEMSpecification_EAmodelRev10.pdf declares that emergency head unload count is limited to 20,000. Possibly there is no emergency unload, but the sound is very unpleasant. P.S. my previous HDD died after 1 year of daily use of FreeBSD-6.3 on the same laptop. >How-To-Repeat: >Fix: Could ata driver issue Sleep or Standby command at power-down as recommended in the above document? >Release-Note: >Audit-Trail: >Unformatted:
