Intel SSD 520 Series Disconnecting/Reconnecting, what to do?

Abount an year ago I bought an ASUS Zenbook UX32VD with an Intel SSD 520 Series 480GB.

I got rid of Windows 8 (that ended up inside Virtualbox) and installed Linux, that time was Linux Mint 14 Nadia and now I have Linux Mint 17 Qiana, since the beginning I noticed occasional crashes that the logs ended pointing out the culprid was the SSD drive.

The kernel keeps logging that several times a day:

kernel: [15833.344939] ata1: exception Emask 0x50 SAct 0x0 SErr 0x4090800 action 0xe frozen

kernel: [15833.344952] ata1: irq_stat 0x00400040, connection status changed

kernel: [15834.109697] ata1.00: configured for UDMA/133

kernel: [15834.124335] ata1: EH complete

It says it needed to hard reset the sata link.

Occasionally it keeps doing that, downgrading the link speed to 3.0 Gbps then try with 1.5 Gbps, never stops and the system crashes.

I readed a ton of claims of people with the same problem principally with lenovo computers and the solution is always the same "I ended up exchanging my Intel 520 SSD for a Samsung 840 Pro" and now I don't have any problem.

I have a Samsung 840 Pro SSD with 512 GB that doesn't do that. Another interesting thing that happens with my Intel 520 and not with my Samsung 840 Pro is that if I put them in an external USB 3.0 case (I tested with a 2.0 USB case of another brand too), the Samsung works fine, but the Intel SSD keeps disconnecting and reconnecting all the time at a point to be impossible to use it, no matter what the computer/system I connect it to, Windows/Linux.

Is that normal? An Intel 520 Series 480GB SSD be unusable through USB, and only be usable because the kernel can handle its disconnections when connected through the SATA connector, and still ocassionally crashing?

I was considering buy another Samsung 840 Pro as the Intel 520 one will not serve me even as a backup drive.

Found other complaints about this same 520 Series SSDs here in the community. Seems I just bought a known crappy Intel product with a Sandforce SF-2281 chipset. Known to be a chipset with a crappy firmware even here.

Hi edmundo_vn, there are some steps that may help:

I hope the above suggestions help.

My BIOS is already the latest one for UX32VD (214).

If you see the link you gave me and the above SMART information, I'm already using 400i firmware since I received the SSD. issdfut_2.0.13.iso don't have any update.

If I do a secure erase will it work inside an USB case and stop powering off/on by its own? Besides loosing 2 or more days of work to reinstall everything and not pretending to mess with the host protected area (that I don't have sure if helps with wear levelling) I don't see the point.
