That controller also has a SATA port multiplier, see here for a recommend controller:

 

 

 

Hi thanks for your reply,  

I changed the SATA cables to the ASM1166 ports on the controller, this seems to reduce the ATA errors to just 1 drive (ATA1) this is the emulated disk that im rebuilding. a example is shown below:

 

 

for more detailed info I uploaded the diagnostics as well.

 

 

is it a option to format the rebuilding (Disk 1) remove it from the array and rebuild it using the parity but then on a formatted disk?

 

 

 

btw. Disk 1 (the one that is causing issues) doesn't use the raid-controller but is directly connected to the motherboard as shown on the screenshot below.

No.    The rebuild overwrites every sector on the drive so whether it is formatted or not is irrelevant..

 

You need the drive you are going to use to stop throwing ata errors to get a clean rebuild.

Have you also checked that the power cabling to the drive is OK?    Power related issues can slso cause the symptoms shown in the syslog.

 

Try replacing SATA and power cables for that disk.

Hi thanks all this was the problem!

 

I changed the power cables and the speeds are now as they should be, 200mb/s a second

I want to thank @JorgeB and @itimpi  for your help and patience with me. you guys are doing gods work!
