I ran s.m.a.r.t and came up with some weird errors, although the disk is pretty fresh Power_On_Minutes 427h+41m

I'm curious, are these the errors of previous hdd?

Error 1 occurred at disk power-on lifetime: 13729 hours (572 days + 1 hours)
  When the command that caused the error occurred, the device was active or idle
Error 2 occurred at disk power-on lifetime: 23300 hours (970 days + 20 hours)
  When the command that caused the error occurred, the device was active or idle.

Here is the output

# smartctl --all /dev/sda

Does this HDD may fail soon and needs to be replaced?

    It's a $30 drive. IMO, it's not worth the time and effort trying to investigate it when at the end you may determine you need to replace it. Just replace it, move on. –  Dec 01 '16 at 00:43
  • It's a small atom dedicated server so I'm not able to replace it myself. Need some opinion based on the output i posted. The HDD says it has ~400h on while those errors indicate x,xxx hours messages – Chris Dec 01 '16 at 01:05

    The drive failed some time ago. And I don't know why you call it "pretty fresh" as it's clearly well over two years old. The Power_On_Minutes attribute plainly does not reflect the drive's actual service lifetime. – Michael Hampton Dec 01 '16 at 01:07

    If by dedicated server you mean it's rented from a service provider, then my opinion stands. Only stronger. You're paying for functional gear. You shouldn't be paying gear with potential issues (I don't anyway). Contact your provider and tell them the errors. They should offer you a replacement or an explanation. –  Dec 01 '16 at 03:03
  • Thanks for the help guys, the HDD will be replaced by the service provider. – Chris Dec 01 '16 at 13:03

When you poll for SMART data you're not getting it from some cache, but directly from the drive. It will never show you the results of an old drive. In this case, your drive is failing and it's time to chuck it.

I on the other hand don't see anything even remotely suggesting that the disk is falling. There's no common symptoms of dying disk in counters like:

  • Reallocated_Event_Count - 0
  • Current_Pending_Sector - 0
  • Offline_Uncorrectable - 0

But instead you're seeing this:

  • UDMA_CRC_Error_Count - 2

I would not bother with that. Cyclic redundancy check (CRC) is a method of verifying and correcting data after it is sent. What this warning is telling you is that at one point, data being sent/received by the drive failed this check. The most common cause for this is a faulty cable or disk controller. Noise or resistance may cause a bit to be flipped.
