I have a disk, that gets me kinda weird smartctl output. I have never seen such large nubmbers on other disks.

Does anyone now how to interpret these ? Is the disk likely to be faulty ?

According to this useful table on Wikipedia, the only critical value in your case would be

188 Command_Timeout  0x0032  100  100  000  Old_age  Always  -  4295032833

The count of aborted operations due to HDD timeout. Normally this attribute value should be equal to zero and if the value is far above zero, then most likely there will be some serious problems with power supply or an oxidized data cable.

I would also check if your file system detected anything out of the ordinary and do a full scrubbing of all disks if possible (assuming you use file systems with integrity checking, like ZFS or btrfs) to catch any hidden problems. SMART attributes are useful to see when you should start ordering replacement disks, but it can't answer the reverse question "Is everything alright currently?" - except for a "Probably yes, but who knows...".
