Hi, I need some help. I noticed the server was in recovery mode. It
had just dropped a "faulty" drive. I checked the drive and it
looked like it was working. When the recovery was done I added the
drive back, after recreating the partition.

As soon as I did it, mdadm informed me that it redropped it and
dropped another drive at the same time. I removed both driver and
added a brand new drive (second is on the way) which the system
accepted and started recovery.

What I don't understand is that I plugged the drives on another
computer with sata-USB adapter and performed a full smart checkup
which returned successful, minus a few bad sectors and some
warnings of pas over heating. What is going on? Thank you for your
help.

No one replied?  I felt sure someone else would.

No one else saw it.  The message you quoted is not in the archives, and
I never got one directly.

Maybe you  have a problem with your driver card, or with a cable, or 
something.

Or normal UREs.  Dragos, please also share your smartctl reports (with -x).

Normally if md stops a driver there will be messages in the kernel
log about access failures.  Do you still have all the logs from when
this  happened? Are there any messages from the kernel?
