Hi,

 

In the automated process of copying cache to the raid, I'm getting a whole bunch of these errors

 

Mar 6 10:05:01 Tower kernel: ata7.00: exception Emask 0x10 SAct 0x0 SErr 0x780100 action 0x6

The cache drive is on a separate 2 change pcie x1 card, with the main array using the motherboard drives. Is this indicative that the pcie card is faulty?

 

The card is a generic JMicron JMB363 based card.

 

Any help most appreciated.

The bad CRC (Cyclic Redundancy checksum) Handshake indicates the communications between the disk and the controller is faulty.

 

It could be:

A bad/poor quality cable

A loose cable

A cable picking up noise from another it is tightly coupled to.

A bad disk controller (or controller port)

A bad disk drive

A bad (marginal/noisy) power supply.

 

I'd try a different SATA cable first, then a different port, then go from there.

Hi Joe,

 

Thanks for that, given me quite a list to check through

 

Cheers
