USB Transfer Speed from External HD to T61P - SLOW

[onix]

I get slow transfer speeds of large files from an external harddrive to my T61p.  The details:

• External HD: Hitachi DKF23FB-60B
  
• OS: Vista x64 SP1
• Memory: 4GB
  
• Current transfer speed ~8.11MB/s

USB 2.0 is supposed to be able to do ~60MB/s (480Mb/s).  I had to completely format the T61p harddrive and reinstall the OS, as I screwed up installing a dual boot.  The system otherwise is doing great.

Any ideas for diagnosis??

I also am experiencing extremely SLOW transfer speeds of files between an external harddrive and my T61.

The details:

External HD: SimpleTech Model 96300-41001-073

OS: Windows 7 x64

Memory: 4GB

Current transfer speed ~8.80 KB/s

• Machine is setup dual boot.  When switched to Windows XP Pro x86....the slow speeds are not experienced.
• Copying to/from a USB thumb drive is not experiencing slow speeds.
• Find no useful information on SimpleTech website.  Have made two requests for help from SimpleTech with no response.
• Lenovo site does not list this explicit problem.  However a similar problem was noted.  It's fix was made available in a BIOS update which I applied.  The BIOS update did not correct my problem.  (re: http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67989)
• All relevant (as I could determine) fixes listed for the beta of WIN7 Beta have also been appplied.  I find no updates for WIN7 RC.

How to further diagnose? 

Fix to apply?
