I do think it's valid to prevent idiot customers from installing drives that use too much power or run too hot, or desktop drives that don't support fast-fail reads, thus driving up Dell's support load, but it sounds like this is more of a lock-in attempt.

This is kind of a dumb move on their part .... most enterprise buyers will buy drives through them anyway for support reasons, and the low end guys who are price sensitive will just take their business elsewhere. I'm not sure who thought this would increase revenue materially.

Cheers
Dave

In the post to the dell mailing list (
http://lists.us.dell.com/pipermail/linux-poweredge/2010-February/041335.html
) It was pointed out that the user had installed Seagate ES.2 drives,
which are enterprise class drives that have been around a while and
are kind of the standard SATA enterprise clas drives and are listed so
by Seagate:

http://www.seagate.com/www/en-us/products/servers/barracuda_es/barracuda_es.2

These drives were marked as BLOCKED and unusable by the system.

The pdf linked to in the dell forum specifically states that the hard
drives are loaded with a dell specific firmware.  The PDF seems
otherwise free of useful information, and is mostly a marketing tool
as near as I can tell.
