Is my HDD falling?

Question

I tested my HDD with command:

smartctl -t long /dev/sda

I checked status of test with command:

smartctl -l selftest /dev/sda

This is the output:

smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.18-348.3.1.el5] (local build)

You seem to have only 3 bad sectors. I had 36 reallocated sectors on a hard disk and it worked fine for about 9 months or more until I replaced it with something else. Though, this is only anecdotal, there are disks and disks. The safest thing to do is replace it. — Cristian Ciupitu, Apr 07 '13 at 03:09
Only "3" Offline_Uncorrectable is **the beginning of the end**. Listen to [mdpc](http://serverfault.com/a/496914/140016) and @CristianCiupitu, and replace it ASAP. — Deer Hunter, Apr 07 '13 at 05:46

Yes, your hard disk is failing. I'd replace it relatively quickly.

Your Seagate Drive has only done 6,5 K Hours of work and is starting to fail, this is rather unusual.

SMART is however telling you to replace it.

Normally HDD's are designed to last at least 10K hours, so you might still have a chance to replace this under Guarantee, but I would not waste too much time on this.

Doing a fast search on the Net came up with some complaints with this Drive. Seems like Seagate bought Maxtor, and since then have produced rather questionable SATA Products.

If you buy a new one, rather go for Western Digital. If you have the money, I would suggest a Intel SSD drive.

Whatever you do, now is the time to make backups of your DATA

I had bad lucks on these two brands (SMART #5 error occured in less than half a year), maybe it's because of I bought HDDs from internet (newegg China), you know, bad things can happened in logistics/delivery step. Then I bought a Hitachi HDD **from local market**, good luck is back now (more than 1 year) — LiuYan 刘研, Apr 07 '13 at 08:19
