Hi all,

I just saw that smartctl gave me the following report for my SAMSUNG HM160HI:



ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
1 Raw_Read_Error_Rate 0x000f 100 100 051 Pre-fail Always - 7

5 Reallocated_Sector_Ct 0x0033 252 252 010 Pre-fail Always - 0
9 Power_On_Hours 0x0032 097 097 000 Old_age Always - 1764

199 UDMA_CRC_Error_Count 0x0036 252 252 000 Old_age Always - 0
200 Multi_Zone_Error_Rate 0x000a 252 252 000 Old_age Always - 0


There seems to be some scary stuff there, such as the insanely high values for Start_Stop_Count and Reallocated_Event_Count and the high value for Offline_Uncorrectable. My laptop is a Dell Vostro 1400 and only a couple of months old. I didn't notice any failures and both fsck and badblocks report no problems at all. How worried should I be?

Guys?

Sorry for bumping this, but I'm very worried.

I think its likely those numbers are incorrect for some reason or another. The start/stop on my 6 year old desktop is 1067, and my laptop is 4882, and its only a year or so old. Neither of my computers have the other number. I'd do some googling and look for some information on what these counts are before I get all worried.

Thanks, Whiffle.

By the way, I'm also wondering why there's no Load_Cycle_Count listed.
How can I know if I'm suffering from the infamous head parking problem if it's not listed?

Can someone shed a light on this?

Okay, I'm getting more and more confused...

If I understood correctly, the VALUE field is nothing more than a normalized version of RAW VALUE. So why the RAW VALUE of Reallocated_Event_Count, Current_Pending_Sector and Offline_Uncorrectable are increasing quite rapidly while VALUE stays unaltered?

Need some help from a S.M.A.R.T. expert...
