So I presume that at this point, you have tried swapping the cables so<br>
that the bad drive is on cables that are known to work with one of the<br>
good drives. Have you then tried using those same cables on a good<br>
drive, and plugging them into different SATA ports to ensure you do<br>
not have a bad SATA port? Or more than one bad SATA port, as they are<br>
usually paired and a pair of SATA ports uses the same hardware inside<br>
the motherboard chipset, so if one port goes bad, usually both of the<br>
ports in the pair will be bad.<br></blockquote></div></div><div dir="auto">There are only four sata ports on the "Elite Group" mobo, all in use with on OS and three recordings drives</div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Have you tried physically swapping the drive positions in the case, so<br>
the bad drive is in the place where a good drive works?<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">It has been in the box, and out of the box</div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
You mentioned having a PCI card with extra SATA ports. Is that<br>
actually a PCIe card? I would hope so, as a PCI card is not fast<br>
enough to run a single SATA port at full speed, and modern drives need<br>
a 6 Gbit/s SATA port. If it is a PCIe card that can do 6 Gbit/s, you<br>
can try swapping drives to run from there instead of the motherboard.<br>
The PCIe card will likely have a completely different SATA controller<br>
and may work differently, so if what you are up against is a SATA<br>
controller device driver bug in the kernel, you will be using a<br>
different device driver that may not have that bug.<br>

What is your motherboard? There are known bugs in the device drivers<br>
for old Nvidia motherboards that make some drives do bad things - I<br>
have an old Nvidia board where my Samsung 1 Tbyte drive will not work<br>
- I have to run if from a PCIe SATA port. I bisected the kernel and<br>
reported the changes that caused this, but to date it has not been<br>
fixed.<br>
<br>
Physically, how are your drives arranged in the PC? Are they in a<br>
drive cage that has them crammed together? Do they all get reasonable<br>
airflow?<br></blockquote></div></div><div dir="auto">They are in a cage with empty slots between each</div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

One thing to try is see if you have enough room to operate the problem<br>
drive outside the case. I have three drives running like that and<br>
they all run cool just by being outside the case and standing on their<br>
sides, so they cool well by simple convection. To make that work, I<br>
used an empty card slot in the case to allow me to pull out a SATA<br>
power cable and got some longer SATA data cables. Leaving off the<br>
backplate that normally covers an empty card slot allowed me to pull<br>
the cables through easily and just sit the drives out the back of the<br>
PC.<br>
<br>
I have put some photos on my web server to show how it works:<br>

<br>
The old blue rag underneath the three drives is to prevent noise - the<br>
wooden table underneath picks up the drive vibrations and amplifies<br>
them enough to make it quite annoying. With the blue rag, they run<br>
almost silently.<br>
