Neither do they - they’re just making it up because they have nothing better to do than bitch about zombie threads. 
Hi and wonder if anyone can help
I have the Drobo FS 5 bay with 5 off 2 TB Samsung F4 hard drives about one year old and last month one HDD shows it is faulty via the red light i have sent the 2TB drive back to Scan and was charged £20 as no fault found.
Scan has sent it back and I have replaced it today and drobo is telling me it is faulty so short of ordering another 2 TB HDD to try out is there any thing i can do?
Many thanks
It’s double zombies! All across the sky!
Actually chillypalmer, the particular forum where this particular old thread is? It’s a forum for complaining and bitching, not usually a forum for getting reasonable replies. You should probably start a brand new thread in “General Questions”.
That’s where the smart people hang out. Mainly smart-asses in here.
Even with the snark The Pit is probably as useful as most of the tech message boards I’ve endured.
I feel bad about replying to a zombie thread, but since I’m hardly the first…
chillypalmer, I know nothing about Drobos, but I’ve put in my time in tech support, so I’ll take a stab at this.
If the drive has been shown to be good, but your Drobo is reporting it as bad, it sounds like the new question is “What’s wrong with the Drobo itself?” That is, why does the bay think a good drive is bad? Could it be a connection problem, or an error on the controller car? Does the manual / product documentation / site / support forums say anything about that?
