Patch for 1gb and larger disks
2007-12-25 7:53:00
Most of you gave the correct answer. There is no patch for 4.1. Thus I will be upgrading to 4.1.1 and install the patch 100343-05.

> Using the format "repair" function I reassigned block # 2676800 (28D840x). The Flexstar tester reports block # 576648 (08D840 hex) to be reassigned.
> Using the Ancot bus analyzer I verified that the driver is issuing a

> User data will remain intact, but since the block in error is not being
