All,

 

Just wondering if there is a way to test this SATA adapter for problems? I'm getting issues while trying to add a third hard drive to the card... it times out and gives an error.  I have successfully had 2 hard drives on it, but it seems adding a third on any port messes it up...

 

Ugh.

I have two such cards full with drives and they work great! However, I don't know how to test them. Have you tried the supermicro page, there is some software for those cards?

I've also got one of these cards which causes unraid to lockup when used,  My system is based on the Gigabyte GA-MA74GM-S2H.

 

similar sounding problem,  i had a single 500gb drive on it originally and it worked fine,  parity checks were fine.  Decided to remove my 3114 based card and put the drives on the Supermicro card after that point the system would generate lots of errors and periodically lockup.  Pretty sure the errors I had were timeouts of some sort.

 

I need to test the card in another machine to confirm that its OK but haven't had time. 

I called SuperMicro and they said to send it in for a warranty replacement as it's still under the 120 days. I brought the card to my PC and started hooking up drive to the different SATA ports and still had the same problems. I'm hoping a new card will fix these problems...

hmm hopefully I can RMA mine too, assuming I ever get a chance to test it

Update: I received my SuperMicro card back from being RMA'ed (new one sent) and it still doesn't accept a third hard drive. So I was digging around and that is when I thought... you know I've been plugging Samsung only drives into the card, maybe there is something with Samsung's. Sure enough... I plugged in a Seagate and it recognized the HD quickly. It appears there is something going on with the 1.5TB (only one's I've tried) Samsung's and this card.

 

Anyone else have this problem or successfully using Samsung HD's and this card?

hmm funnily enough I had Samsung 1.5gb (HD154UI) drives attached when I had issues with it,  I've tested the card in another machine and it seems fine, not got back around to putting it back in my main box yet.

It would be interesting to see how your testing goes...

Think I have a spare Samsumg somewhere,  maybe if I get time this evening I'll try doing a preclear using the SuperMicro card.

Recently, i had a strange problem with this card on an Asus p5wdg2-ws-pro motherboard and two Western Digital 2TB drives.  When i added the new drive, i wasn't able to format it from unraid web interface, and i also couldn't initialise it from JoeL's preclear script.  In both cases, at the moment of the first write, my server completely hanged, and the only thing that i could do was to press the switch. The result was that i didn't have any syslog to check, so i was stuck.  No cabling change, power change, or another port on the card, helped.  Searching on the internet found conflicting posts on the subject about if this controller supports disks over 1TB or not.  There were people saying they had done it, and other saying that it just can't be done.  Some even got email from Supermicro saying that hdd sizes over 1TB aren't supported, and no new firmware will be produced.  So i thought that there is no other solution, than to use onboard controllers instead of Supermicro for these two disks.  This, worked like a charm, although i was upset that i would have to find another controller that was compatible with large disks. 

Couple of days ago found on a post how to make syslogd to write to usb, so even if the server hangs, something close to the error would be there.  So i moved the hdd back on Supermicro to give it a go and holded my breath. 

And it works like nothing happened since then!  i also tried different ports of the card just in case.

So after all this looong talk, my sujestion is, to format your disk on another sata controller and then move it on Supermicro.  I can't assure you, that it will work for you as it worked for me, but you lose nothing to try.

 

Good luck,

Andreas

Seems others are using this card with these drives without issues :-

Yes, this is one of the many forums that i stumbled upon, with conflicting reports about the compatibility of AOC-SAT2-MV8 with larger than 1tb drives.  There were posts on avsforum, too.  Some people also claimed that this controller doesn't support specifically Seagate drives, or specific models of Western Digital drives, but others reported to use them with no problems.  Initially mine didn't work either, but now - fingers crossed - works fine for a couple of weeks now. 

Forgot to say, that i removed the card from unraid, put it under windows 7 and i was able to format, read and write the drive.  mayby (although doubtfull), something in the implementation of the linux driver / module (excuse my linux ignorance) has a bug

Interesting results there. So my problem start when you boot the server once it identifies the card it hangs there. It will find the first two hard drives that are plugged in, but then the third (which was a Samsung) would not be identified and therefore you would never see it on the unRAID menu. I just ordered another Samsugn 1.5TB from Newegg and plan to see how that goes LOL

 

I might be getting rid of this card and going with the one that Tom uses on the pre-built arrays!

Sorry to hear that.  So it seems that this controller is really more uncompatible (if there is such a thing) with your Samsung, than it was with my WD.  Unfortunatelly i don't have any Samsung nor i have any source to get one just to do a test for you.  Is there any chance that Samsung has released any firmware update for your model?

I tested this again by the way,  a 1.5tb Samsumg,  2tb Hitachi and a 500gb Seagate.  It ran through a full parity check fine and I tried the disks in various positions on the controller (just accessing data on disks) and didn't manage to get it to hang once.  All the same I think I'm going to ditch it, get a 4 port PCI-E card and then upgrade the smaller disks in my system with 2tb ones, that would give me enough room for the next year at least.  Hopefully something better will come along by then.

So, your SAT2-MV8 works fine and it gives you 8 ports but you are gonna to ditch it anyway?

Since it caused my unraid server to lock up every time I used it "working fine" is relative in this case.  All my testing proved is that it worked fine with the 3 drives I had available in a different system.

I got this card with 8 hdds. All WDs.  3x1TB and 5x2TB.  Haven't noticed any problems yet (knock on wood).  I got another one on order to slap onto the same box.  Seems like this card has compatibility issues with Samsung from the reviews I read on Newegg...
