Rebuilt server in new case using new cables getting some errors

[Maticks]

Can anyone help we work through these error problems.

I have 16 Data Disks and 2 Parity disks

before I did the case move one disk Z300RXT7 was doing  udma crc error every now and then i assumed it was the SAS to SATA cable.

So i've rebuilt it in a new case with new cables for all the drives.

I had some read errors and UDMA CRC Errors on one drive WCC7K5FREDXX doing a party check after so i changed out the cable assuming it was faulty. That seem to get rid of the errors messages.

but shortly afterward i started seeing  reallocated sector ct on one of my disks ZGY04GN9 went from 1000 to 14000 within an hour or two so replaced it with a new disk and rebuilt the array. That disk is now stable.

 

But overnight the disk i mentioned that was doing the udma crc error is now on fresh cabling and now doing reallocated sector and the odd offline uncorrectable and current pending sector label Z300RXT7. This disk unlike others is part of a cache pool so wasn't under stress when i was rebuilding my array.

 

Is all this a coincidence and moving the system and drives around for some these 4 year+ drives just too much and they have died?

Or is there a possibility of something more and the disks are actually fine?

Reallocated sectors are not a SATA/SAS cable problem, either the disks are failing or you have a power problem, insufficient or intermittent power issues can reallocate sectors.

I am now seeing UDMA CRC errors not sure if it is a cable issue now its on that same drive i was seeing the reallocated sectors on before.

Those are usually a SATA cable problem.
