This is how I Fixed the ZPOOL error afterI Upgrarded 2 new hard drive to do Mirror

[idd]

I install FreeNAS 8.2.0-RELEASE-p1
and was testing Mirror with 2 hard drive so I install 2 160gb sata hard drive and did mirror everything was running fine for month after all the test I did with these hard drive and it was perfect.

Then i decide to go full blown and bought 2 new sea gate 2x 2 TB hard drive hook them up did the ZFS to Mirror
everything look perfect i start to transfer file half way i get error so i formatted the new hard drive again then transfer again
still same problem..


then it clicked i bought a a 16 channel security recorder 2 week before and I had the same problem the sata cable that came with it
i connect to the hard drive switch on security recorder and it would not detect it. for week I try to fix it.

then just as I was about to thrown it in the dump I change the sata cable to new one and the dam thing picked up and is working till this day

so I Decide to do the same to freenas and put in 2 brand new sata cable and the dam thing been working since now
i have no more zpool error all is well and have green light on and healthy hard drive..

so guy if you have problem try it...
