Hello,

I have from the topic this hard drive in my arrey with this LSI Card in IT mode "HP LSI SAS SATA IT Mode 9205-8i" every time I plug these hard drives into this LSI card i get lots of UDMA errors I'm guessing this card cant handle the 8TB hhds, if I'm correct what LSI card in IT mode will support these cards fully? I currently have them plugged into the motherboard which is a word around I have 2 6TB & 1 4TB plugged into the LSI card with no problems.

 

Thanks for the help on this odd quest.

Make sure you don't have this situation:

I also looked at your Diagnostics file.  You have 4 WD 8TB drives in there.  They have 33, 11,937, 1337 and 0 CRC errors on them.  The drives also have about 12,000 hours on each of them.  You do know that CRC errors are never reset and, if the drive never gets another one, the count will remain exactly what it is today forever.  So, are these errors happening now or did they happen in the past?  (As I recall on the DASHBOARD page, you can turn-off the CRC warning for a HD until a new error occurs.)

 

They are also relatively harmless as the data will simply be resent until the CRC is received correctly.  The only damage is to the data rate when the error occurs because of the retransmission time.  By the way, CRC errors can be generated by cross-talk between cables if you tie the SATA data cables into a tight bundle to make things look 'pretty'!

Hi thanks for getting back to me quick, I'm an IT guy should have gave you more info on the topic at hand. My Server case is this "Rosewill RSV-L4500U" it has a hot swap back plain that the Sata Cables do not touch I uploaded the picture of the backplain I will have no time untill 6am AST time 5am EST time to shut the array down to pull one of the 8TB hhds to see what option it has the 4/6TB i can say has shroud. I'll follow up in the morning time with my finding on the back side as i can't find pictures online of the hard drive.

Good morning Frank1940,

 

Here is my is my finding on the back side of these 8TB hhds, attached is a picture showing that it does have a shroud. With this said now and the back plain being that it touchs first does it still mean WD is saying to use Sata Gen 2 cables that do not have the lock on them? Or is it an LSI card upgrade to the 9300 8i which fully supports the 8TB hhd?

 

As you can see the picture of the 8087 SAS to Sata 3 cables goes from the LSI card to the back side of the black plain again the sata side does not touch the 8TB hhd only the back plain could it be the back plain causing this? Or an very out dated LSI card?

 

Thanks

See if the drive is detected with a Molex to SATA adapter, that will confirm if it's the 3.3v issue.

Hi JorgeB,

 

how do I do this in unraid? The only thing I see is this "SATA version:SATA 3.2, 6.0 Gb/s (current: 3.0 Gb/s)"

Use one of these top power the disk, for testing only:

 

Hello JorgeB,

 

I have the molex to sata power thing attached to one of the 8TB with the Sata cable diect connected, where do I do in unraid to find out 3.3V power? Or is it an app i need?

Nothing.   If it spins up using that connector and does not spin up without it then you have the 3.3v power issue.

Um ok so what does that mean? Is a major problem how can it be fixed if possible? So a hard drive should be using 5V to be powered why is it taking 3.3V?

As far as I know the only "fix" is to buy a drive model that does not have this issue (or to avoid it by continuing to use a power connector such as the Molex->SATA power adapter that does not have the 3.3v line connected).   The other possibility is to mask off the 3.3v pin on the drive SATA connector

@Cobragt88, Google     3.3V hard drive problem    for details on what the 3.3V issue is on certain drives.

So i tested 1 of 8TB hhds by using sata power it spins up at 1st power on too so basicly i'm not sure but its running without problems now hooked up to the mobo, also my friend google says that the LSI 9300-8i will give full support to thoses 8TB's with 12Gbps vs the current 6 that my LSI card does. i'd say this can be closed thanks for all the advise.
