October 1, 200817 yr I've been playing with the unmenu drive management page, and I've noticed high numbers on my Smart Statistics on a couple drives in my system. I have a 500g PATA in my system that I originally pulled from a WD external USB enclosure, and it's getting the following numbers: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 110 095 006 Pre-fail Always - 53456328 3 Spin_Up_Time 0x0003 093 093 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 580 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0 7 Seek_Error_Rate 0x000f 081 060 030 Pre-fail Always - 164049987 9 Power_On_Hours 0x0032 096 096 000 Old_age Always - 4029 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 0 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 98 187 Reported_Uncorrect 0x0032 100 100 000 Old_age Always - 0 189 High_Fly_Writes 0x003a 100 100 000 Old_age Always - 0 190 Airflow_Temperature_Cel 0x0022 068 038 045 Old_age Always In_the_past 32 (Lifetime Min/Max 31/32) 194 Temperature_Celsius 0x0022 032 062 000 Old_age Always - 32 (0 21 0 0) 195 Hardware_ECC_Recovered 0x001a 055 051 000 Old_age Always - 161501831 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 200 Multi_Zone_Error_Rate 0x0000 100 253 000 Old_age Offline - 0 202 TA_Increase_Count 0x0032 100 253 000 Old_age Always - 0 SMART Error Log Version: 1 No Errors Logged I noticed that Hardware ECC, Seek error & raw read error rates are quite high, but there have been no sector re-allocation. Should I be particularly worried about this drive? I also noticed that my 2 other PATA drives are also getting high numbers there as well (as is my cache drive, lol). I am definitely planning on moving the PATA's out of the box, but I and just a bit concerned about the error rates on the drives (they are all high-hour drives, and I'm sure could use replacing, just didn't want to do it quite yet, lol). Of all 4, there has only been one drive that had any re-allocated sectors (just one). I'm also wondering if the errors on the 500g above could be from overheating in the external chassis that it was in previously.
October 1, 200817 yr Those numbers are not always in decimal. In fact it could be a bit mask or hex value being displayed as decimal. There are no reallocated sectors, no pending_sectors, and no offline_uncorrectable_sectors. When these start to go up then it's time to consider retirement. smart LONG test on the drive just to be sure.
October 1, 200817 yr Author Looks like with the new beta, the smart tests through unmenu aren't working (except on the cache drive for whatever reason). I've tried to do a short & long test, and neither go through.. Must have been some temporary glitch, it's running a long test now.

I've tried to do a short & long test, and neither go through.. Must have been some temporary glitch, it's running a long test now. One of the libraries needed is not on the new beta2. See this post: http://lime-technology.com/forum/index.php?topic=2533.msg20174#msg20174 Tom has the new version of smartctl installed, but not the library it requires... Should be in the next beta, but in the interim, you can download and run installpkg yourself. Joe L.
October 1, 200817 yr Author I did that right after installing the b2 build, it's just for whatever reason the drive kept kicking back and showing that no tests were running, although looking at it's log now it appears it actually was running the short tests, just not showing the results.
October 1, 200817 yr All of my Seagates report similar numbers. It seems to be normal for them. Since that is what Error Correction is all about, checking and correcting every bit on the fly, I have to assume Seagate drives are configured to count every slightest hiccup.
October 1, 200817 yr Author I've got that particular drive running a long test at the moment, and I do also notice the drives that are showing the most ECC corrected errors ARE Seagates, the only other drive showing any ECC errors is one of my 300g WD's, but it shows around 6400 or so, instead of the massive numbers both seagates show.. Eases my mind at any rate, although I still want to replace anything less than 640g in my system with at least a 640, or 1tb...
October 1, 200817 yr All of my Seagates report similar numbers. It seems to be normal for them. When the 1TB drives first came out and we put them on our webservers we sorta freaked seeing these numbers. Overall the drives did not give us any issue and it seems the seagates report high numbers in this range, but never really fail the health tests. As I remember reading, the numbers are not always decimal counts, but could be some internal count that is merged with other statistics.
October 1, 200817 yr As I remember reading, the numbers are not always decimal counts, but could be some internal count that is merged with other statistics. You did mention that above, and I had already forgotten it. That does make sense, they are raw values after all. Could be verified by monitoring them for changes, what kind of changes.

Without knowing the protocol for updating the value, it's hard to monitor for for changes that are meaningful.
