Detected increasing uncorrectable error count
Detected increasing uncorrectable errors[88] on disk 3 [ST2000DM001-1ER164, W4Z2EH1R]. This often indicates an impending failure. Please be prepared to replace this disk to maintain data redundancy.
I got these on one drive, replaced it and it works fine. 1 month later the other drive give the same message. Replaced it with a new drive and now while synchronizing i get the messege on the new drive as well..Any ideas?

My main advice is to get NAS purposed drives in the future (WD Reds or Seagate VNs).
I'd exchange the new drive with the seller - if you return it to Seagate they'll replace it with a recertified drive, not a new one. If you can, get an st2000vn0001 or WD20EFRX instead.
In case this is useful:
Reallocated Sectors, Pending Sectors and Offline Uncorrectable are errors due to the drive itself, they're not caused by the chassis.
ATA Errors can be caused by either the drive itself or the chassis.
So if you have drive errors, as StephenB advised, you should contact the drive seller or manufacturer depending on your warranty.
Using NAS drives (WD Red, Seagate NAS HDD) would help, making sure they're in a good environment as well (not 80°C, chassis not on a vibrating area, don't move the chassis while powered on, etc.)
