I cant figure out, whether disk is failing or esxi has problems with disk driver.
I am using Asus ASUS M2A-VM
Disk controller shows on esxi as: SB600 NonRaid 5 SATA

It looks like one of your disks, a Western Digital i'd imagine, may be having physical issues. There are diagnostics available from WD you should probably run against the disk. Might be a good time to take a backup as well.

I sincerely doubt this is an issue with the "driver" as there are little to no configuration options there to be misconfigured.

Recovering ESXi datastore

Buy a new drive then, using a linux boot disk, dd the old drive (from USB) to the new drive:

dd if=/dev/sd<olddrive> of=/dev/sd<newdrive>

Because VMFS, the ESXi filesytem, is proprietary, you will not be able to find any drivers, or mount the drive to copy your vmdk files. This may change, and you can use adapters, but your best bet is to transfer your old ESXi disk to a new one, bit for bit.

ESXi add datastore without partitioning

You don't want to add a datastore (which is used to store virtual machine images and ISOs, not data files as seen by a guest OS), you want to add the disks as Raw Device Mappings to the VM in question. In the VM hardware settings, click Add, Hard Disk, then choose Raw Device Mapping rather than a new or existing virtual disk.
