For the IBM's it depends what the problem is. Spontaneous bad blocks
appearing during power off appears to be fixed by the firmware update

Thats up to the owner. There are lots of uses for such drives - /tmp,
swap, in a raid array, etc

Mind you I collect drives that have nice properties like "hangs the

Very good question... 

the DFT has finished it's work, and tells me no more bad sectors are 
present... for how long?

To the swap guru's: what does linux do if it attempts to write to swap, and 
gets an error code returned from the ide layer?

Be careful of these even in a RAID array; they will go bad silently.
I had one array (software RAID5, 8 75GXP drives on a 3w6800 in JBOD
mode, one hot spare) that was going fine until one drive died hard,
wouldn't spin up, etc.  I replaced it, but during the RAID resync
three other drives were found to have errors.  The array was trash,
but luckily all drives were dead just at the tail end, so I could copy
the data out during the RAID resync.  Some of the failed drives had
the updated firmware.

3ware has background integrity scans now; I don't know if software
RAID has any equivalent besides an occasional 'dd', but even that's a
good idea.

Having two of such notorious broken drives in a RAID array is also
not an option in many cases. Mirroring is meant to increase data
security in case a drive fails spontaneously; using particularly bad
drives for that purpose is a way to work against the reason.

You probably should keep a DeathStar as the worst drive ever made.
Heck, if my latest replacement drive from IBM ("serviceable used part")
starts failing again I might as well ship it to you instead of IBM.

I am sorry, what part did you not understand?

IBM == Big Corporation of decoupled divisions equal to "Two Zaks" by Dr. Seuss

The communication is going the same direction.

I simply wondered why ibm moaned about supporting linux loads, yet don't have a decent linux flash update for their drives. If their stuff is written in C# why don't they port it to Ximian Mono?

Hell.Surfers,

Because when I was booted out of 2.5, effectively, the API for DFT was
deleted.  So you take away the means to make it work, and they stop moving
that direction.  Now that -AC series has the API, and 2.5 will see a full
return of it, I now have to restart the process to motivate them again.
However since Hitachi may end up buying out IBM's disk manufacturing
business and their product lines, I now have to go an try an court (old
dating term for the post 70's crowd) Hitachi.

Now, what do you want?

Why don't IBM do a Linux version? Don't they have a linux firmware utility? I thought IBM had a campaign to support linux...

The firmware update is for many more drives than that, My own

     Model=IBM-DTLA-305040, FwRev=TW4OA60A

is also recommended, as well as many with a FwRev=xxxOyzzz with zzz<66A.
Now i have to find a windows machine to try it out on...
