TITLE:  Large Capacity HD Interchangeability
 
 
SUMMARY 
 
   The user may encounter an issue accessing a hard disk drive after 
   transferring it from one platform to another.
      
   This condition can occur if the capacity of the hard disk drive 
   is greater than 528MB and a user moves it between platforms with 
   different BIOSes.
   
   BIOS manufacturers use a variety of schemes in implementing the 
   translation geometry to support large drive capacities, beyond 
   the 528MB physical limitation. The incompatibility issue will 
   occur when the hard drive logical geometry scheme between the two 
   platforms is different.    
 
 
NOTES 
 
   AST suggests the following:
   
   1. To prevent loss of data, back up the hard disk drive 
      prior to moving it. 
   
   2. Repartition and format the drive ON TO THE NEW 
      PLATFORM. 
   
   3. Restore the original data to the new hard disk drive.
