ST340823A disk size issue - Revisited

[Eddie Atherton <stunnel@attglobal.net>]

Hi,

I found the above thread while searching for the reason I was getting 
lots of errors while trying to build out a new server.  Yes, I am using 
an ST340823A drive.  However, I am getting slightly different results 
for the drive capacity, which I'm not sure if that could cause issues 
with the patch.

I actually have 2 of these drives.  One is in a WinBlows machine, and 
the other is in my new server.  Using an Ubuntu Live CD, I was able to 
verify that the drive in the WinBlows machine is behaving exactly the 
same as the original problem report.  However, the drive in my server, 
running Slackware 11.0, reports a different "current capacity", as shown 
here:

And a diff between the 2 disks:

48c48

---
 >       not     frozen
52c52
<       CBLID- below Vih
---
 >       CBLID- above Vih


I also ran the Ubuntu Live CD against the server, and it reported 
exactly the same values and errors as Slackware, so the difference in 
kernel level is not an issue.

I'm quite happy to try and build a kernel with the patches, to see if it 
helps/fails with this different capacity, as long as someone can point 
me at which level to download, and which patches I need to apply.

Cheers,
Eddie
