SAS Smart self test results confusing.... Help needed

[nasnice]

Hi all,
I am currently in the process of building a new NAS and was doing the hard drive burning in procedure per our forum guide.
Encountered some strange results and since this is my first SAS build I am at a loss wat to do...
System is a Non ECC motherboard with the latest Freenas release 11.2-U7. Using a Dell HC310 SAS controller flashed to IT mode and here is my first question.

During startup this controller is identified as follows

Code:

Nov 28 06:16:22 freenas mps0: <Avago Technologies (LSI) SAS2008> port 0xe000-0xe0ff mem 0xdf140000-0xdf14ffff,0xdf100000-0xdf13ffff irq 16 at device 0.0 on pci1
Nov 28 06:16:22 freenas mps0: Firmware: 20.00.07.00, Driver: 21.02.00.00-fbsd
Nov 28 06:16:22 freenas mps0: IOCCapabilities: 1285c<ScsiTaskFull,DiagTrace,SnapBuf,EEDP,TransRetry,EventReplay,HostDisc>

So the Firmware is @ level 20 and the driver is 21 is that a problem?

After the first smart test I checked for results and got the following (the output of the smartctl -a/dev/ad0 came in little chunks and took 3 minites to complete...)

This drive is definitely bad or is it?

This is so different from the SATA Smart results that I have problems to interpret this information... what is important... and what not... Looked around but did not find a definite answer... did find many more confused user topics...

Specifically what Correction Algorith invocations mean... is that a normal value?
Thanks in advance for any insights...

HBA drivers often don't match the firmware so I wouldn't worry. Although I don't have that card I think the general feeling is that you should try and have the latest firmware unless there is a known reason not to.

Regarding the drive then I have LOTS of SAS drives and can confirm that drive is bad.

'Failed in segment' is a common failure in HGST drives and as I have more than a thousand I speak from experience.

Just found out that my new drives are not eligible for the HGST warranty... HGST suggest to resolve this with the supplier... Bought them (6) through Amazon... Will return the lot and order really NEW drives... Found a remark on a German forum that these drives may be reconditioned or OEM surplus... My bad...
Still confused about that smart test result... Could anyone post here a good or perfect smart report on a SAS drive... just for reference..?
