This is serious - Do not use this product without first doing a full
backup of the file system in question.  Do not expect to use this product
without some QA testing.  

A customer of the company I work for recently installed this product, with
disasterous results.  At first 'AIM Disk Tuner' appeared to be working as
advertised, but after several days operation, the super block of the file 
system in question was effectively scrambled.  

Let the guru beware on this one!
