I think that's potentially FUD.  Its all about 'Dell qualified drives'.  
I can't see anything that suggests that Dell will OEM drives and somehow 
tag them so that the drive must have come from them.  Of course they are 
big enough that they could have special BIOS I guess, but I read it that 
the drive types (and presumably revisions thereof) had to be recognised 
by the controller from a list, which presumably can be reflashed, which 
is not quite saying that if some WD enterprise drive model is 
'qualified' then you have to buy it from Dell..

Do you have any further detail?
