SATA: ERROR: Giving up on I/O, Reliance Not Supported on Certain Models?

[PCorcs_DMC]

Hello All, 

I did not want to latch on to a resolved post, but I find the solution a bit under explained. I have a PXI System (8102 Controller, 1078 Low Power Chassis) that encounters the following errors after about 3 days of continuous run time:

SATA: ERROR: Giving up on I/O [0x25] transfer 0

SATA: ERROR: Giving up on I/O [0x35] transfer 0

I have read through this post, seemingly the only other documented instance of this behavior:

http://forums.ni.com/t5/PXI/SATA-ERROR-Giving-up-on-I-O-0x35-transfer-0/td-p/1992475

Proof that this is happening: 

I am going through the process of reformatting to see if FAT32 will stabilize the system for longer run time; however, I would like to know if there are limitations on the use of Reliance as a RT file system? Are there specific models that are not supported? 

The failure modes that indicate this error has occurred are not consistent. I have seen full system crashes when this error occurs, and I have also seen the system in a partially functional state (network communication interacts with my main application; however, the controller cannot be discovered by MAX). Is there any more detailed understanding of this error (and avoiding it), other than 'Something somewhere is corrupt'?

During the troubleshooting process of this issue I have reformatted the system multiple times (though never to FAT32). Is there a fundamental known issue with Reliance or CAR related to this behavior? I will begin FAT32 testing now, but have a few days of testing before I can share results. 

Any insights on this issue are greatly appreciated,

Hello Patrick,

Reliance system, should be compatible with all PXI systems. This is an odd issue that has been observed a couple of times in the past, a few CAR´s has been created, the service requests I checked, all of them ended up in a RMA process. The only workaround among the CAR´s I found is to disable the RAID option if present in the BIOS, however from a technician perspective I would recommend you to perform the FULL FAT32 formatting process ( not a quick format) in order to detect possible bad sector on the HDD, another option will be get a tool like HDD regenerator, that can check and most of the time, repair bad sectors

Hello,

Thank you for the reply, and research. After a Full FAT32 format, the system has been functional for 4 days now (longer than it ever had lasted before). During the formatting process, I discovered no bad sectors; however, I did not seek out a thrid party tool to do further testing. At this point, I am keeping an eye on the system performance, and if I see the behavior again I will start the RMA process. 

Thanks,
