testing. I formatted his drive and wrote a new partition table. Ran Ubuntu from a live USB. Something immediately caught my eye. Now I don't know much about SMART test results, but I know that it's probably not a good thing if the SMART dialog says that the read error rate threshold is 62 and the read error rate value is 1,245,235. Seriously. That's 20,084 times the threshold.

I recently realized that the disk was noticeable slower than before, so I decided to check the SMART data. Everything seemed to be OK. A bit more than a year powered on, head flew for http://superuser.com/questions/867801/high-s-m-a-r-t-read-error-rate 11 months... and all the read errors successfully corrected; no big deals. I decided to note anyway the read error rate, which had a value of 60M (normalized 119, threshold 6, worst 99). Today (3 days after), I checked again those numbers and the read error rate value is at 215M, which seems to me like a huge increase in a little time. The normalized and worst values haven't changed anyway, so the assesment is still OK in the SMART data. Should I be worried? My data is backed up, but should I be already buying a new HDD for my laptop? hard-drive smart share|improve this question asked Jan 21 '15 at 22:09 Peque 551312 It may be simply a loose connection. Try to disconnect the HDD and install it again. –gronostaj Jan 21 '15 at 22:15 @gronostaj: The HDD is mounted with screws, but anyway I will try that. Thanks! :-) –Peque Jan 21 '15 at 22:29 1 There has to be some type of data connection. 215 million errors is not normal.

Capability Enabling SMART Testing a Drive Results Suggested application: GSmartControl Advanced: Running as Smartmontools as a Daemon Actions in case of trouble Utility: Checking all disks at https://help.ubuntu.com/community/Smartmontools once Introduction Smartmontools is a set of applications that can test hard drives and read their hardware SMART statistics. Note: SMART data may not accurately predict future http://serverfault.com/questions/255355/smart-values-high-and-growing-but-indicator-green drive failure, however abnormal error rates may be an indication of possible hardware failure or data inconsistency. This how to will help you to configure Smartmontools to read error do actions such as shut down the computer or send an e-mail when the disk is going to fail. Prerequisites A modern S.M.A.R.T. capable hard disk Setting up Installation You can install the smartmontools package from the Synaptic Package Manager (see SynapticHowto), or by typing the following into the terminal: sudo apt-get install smartmontools Checking read error rate a drive for SMART Capability To ensure that your drive supports SMART, type: sudo smartctl -i /dev/sda where /dev/sda is your hard drive. This will give you brief information about your drive. The last two lines may look something like this: SMART support is: Available - device has SMART capability. SMART support is: Enabled Enabling SMART In the case that SMART is not enabled for your drive, you can enable it by typing: sudo smartctl -s on /dev/sda Testing a Drive You may run any type of test while the drive is mounted although there may be some drop in performance. There are three types of test that can be conducted on a drive: Short Extended (Long) Conveyance To find an estimate of the time it takes to conduct each test, type: sudo smartctl -c /dev/sda The most useful test is the extended test (long). You can initiate the test by typing: sudo smartctl -t long /dev/sda Results You can vi

Now i read that "Disk is healthy". Now i'm not familiar with SMART parameters, but looking at them, there are some insane high numbers and each time i press refresh, they grow. These 3 parameters are high as seen in picture (its really ubuntu, just with mac theme): Read error rate Seek error rate Hardware ECC recovered Should i conclude that the drive has failed? Or may there be problem in controller or cable, motherbord? This is an PATA drive. Also when testing for bad blocks, the test stops ~80%, but it doesn't indicate that any bad block is found. Umm, i checked the ubuntu-drive (which performs good), and those same numbers are high (and growing) for that drive also, but it is connected to SATA controller. hard-drive smart share|improve this question edited Apr 4 '11 at 10:56 asked Apr 4 '11 at 10:49 Janis Veinbergs 88011527 1 If you are having any sort of issues with a hard drive, now would be a perfect time to make sure you have backups of any important data on that drive. The issues might be fixable, or your drive could die tomorrow. –devicenull Apr 6 '11 at 2:30 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted The tests are done by the drive on the drive so your interface to the PC is irrelev
