Sorry for the delay in Posting the Summary

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.

Here's the response from uunet!ebu.ericsson.se!Mike.Rembis

> format functions are limited to 1GB (2^21 bit address). Reassign of a
> block beyond 1GB wraps around to the lower 21 bit address.As a result,using
> a 1.3 GB drive ,for example, the top .3GB will be inaccessible
> without this patch.
>
> 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
> reassign block command for block 08D840 hex, indicating that it is
> truncating the most significant bits of the address and supports only a 21
> bit address in this section of the code.
>
> User data will remain intact, but since the block in error is not being
> reassigned it will continue to fail, which could eventually lead to loss
> of data. Good blocks will be reassigned unecessarily, which can adversely
> affect performance.
