Is it good or not? What I need to do?

I change the cable but it's same as before.

If I chagne the 184 value -151 the HDD is ok.
Whats wrong? CPU, RAM or something else fault?
Whether it is repairable or do I have to throw away the disk?

Can I update Firmware?

Ultra ATA Error Count can be due to a bad data cable, but sometimes faulty motherboards can cause same issue if data channel is not working well.
If Ultra ATA Error Count increase more even with new data cable then MB should be replaced.

I'm not sure, but i think also oxidation on HDA contact can cause Ultra ATA Error, if you see oxidation on the pcb just clean those with a pencil eraser.

The End-to-End Error count reflects problems in the data path through the drive's cache RAM (SDRAM). It appears that Samsung doesn't treat this attribute as seriously as other HDD manufacturers. Seagate, for example, allows for only one error before this attribute falls below its threshold.

See http://en.wikipedia.org/wiki/S.M.A.R.T.

The UDMA CRC Error Count may reflect a compatibility problem with the motherboard's southbridge. For example, certain SpinPoints wouldn't get along with AMD's SB850 chipset and required a firmware update. Intel's P67/H67 chipset was afflicted with a bug that would result in the slow deterioration of the SATA port.

Some drives have a jumper that limits the SATA link rate. Others can limit the interface speed by way of a utility provided by the manufacturer.
