content: Went to the scrapyard yesterday, and in the ewaste pile were a few DVR units, basically just a rack mounted PC case with hard drives and a capture card inside.Capture cards were Geuterbruck LP)/JC pci cards, with a rear panel mounted 16 input board.Hard drives in 2 of the units are Hitachi deskstars, made July 2004. Powered up the one, and it powers up, and still works. too bad it was half of a RAID, so no easy recoverable data, and after 30 seconds I just reformatted it.Powered up Smartmon, and this drive has done 55555 hours of power on. Pretty impressive, it has been running essentially 10 years without any issue.Did it's first self test, and no problems, so went for the full surface scan, and this 11 year old drive passed perfectly, though it runs so hot I have placed a 120mm fan blowing air across the drive, just so it does not act as a room heater.Code:smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-37-generic] (local build)Copyright (C) 2002-13, Bruce Allen, Christian Franke, [url=http://www.smartmontools.org]www.smartmontools.org=== START OF INFORMATION SECTION ===Model Family: Hitachi Deskstar 7K250Device Model: HDS722525VLAT80Serial Number: VN69TECFDG2WRAFirmware Version: V36OA6EAUser Capacity: 250,059,350,016 bytes [250 GB]Sector Size: 512 bytes logical/physicalDevice is: In smartctl database [for details use: -P show]ATA Version is: ATA/ATAPI-6 T13/1410D revision 3aLocal Time is: Sun Sep 27 13:14:19 2015 SASTSMART support is: Available - device has SMART capability.SMART support is: Enabled=== START OF READ SMART DATA SECTION ===SMART overall-health self-assessment test result: PASSEDGeneral SMART Values:Offline data collection status: (0x00)Offline data collection activitywas never started.Auto Offline Data Collection: Disabled.Self-test execution status: ( 0)The previous self-test routine completedwithout error or no self-test has everbeen run.Total time to complete Offlinedata collection:( 5552) seconds.Offline data collectioncapabilities:(0x1b) SMART execute Offline immediate.Auto Offline data collection on/off support.Suspend Offline collection upon newcommand.Offline surface scan supported.Self-test supported.No Conveyance Self-test supported.No Selective Self-test supported.SMART capabilities: (0x0003)Saves SMART data before enteringpower-saving mode.Supports SMART auto save timer.Error logging capability: (0x01)Error logging supported.General Purpose Logging supported.Short self-test routinerecommended polling time:( 1) minutes.Extended self-test routinerecommended polling time:( 93) minutes.SMART Attributes Data Structure revision number: 16Vendor Specific SMART Attributes with Thresholds:ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE1 Raw_Read_Error_Rate 0x000b 100 100 060 Pre-fail Always - 02 Throughput_Performance 0x0005 100 100 050 Pre-fail Offline - 03 Spin_Up_Time 0x0007 101 101 024 Pre-fail Always - 347 (Average 344)4 Start_Stop_Count 0x0012 100 100 000 Old_age Always - 2115 Reallocated_Sector_Ct 0x0033 100 100 005 Pre-fail Always - 07 Seek_Error_Rate 0x000b 100 100 067 Pre-fail Always - 08 Seek_Time_Performance 0x0005 100 100 020 Pre-fail Offline - 09 Power_On_Hours 0x0012 093 093 000 Old_age Always - 5555710 Spin_Retry_Count 0x0013 100 100 060 Pre-fail Always - 012 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 211192 Power-Off_Retract_Count 0x0032 098 098 050 Old_age Always - 2485193 Load_Cycle_Count 0x0012 098 098 050 Old_age Always - 2485194 Temperature_Celsius 0x0002 166 166 000 Old_age Always - 33 (Min/Max 17/49)196 Reallocated_Event_Count 0x0032 100 100 000 Old_age Always - 0197 Current_Pending_Sector 0x0022 100 100 000 Old_age Always - 0198 Offline_Uncorrectable 0x0008 100 100 000 Old_age Offline - 0199 UDMA_CRC_Error_Count 0x000a 200 200 000 Old_age Always - 0SMART Error Log Version: 1No Errors LoggedSMART Self-test log structure revision number 1Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error# 1 Extended offline Completed without error 00% 55557 -# 2 Short offline Completed without error 00% 55555 -Selective Self-tests/Logging not supported

content: That drive is in perfect condition, no reallocated sectors or any errors.The "Deathstar" (75GXP) was made around 2001; yours is newer than that.

content: That's really impressive for a constant write application. I expected one of the heads to have failed by now.

content: Nice find - especially as 250G is still a usable size (and was large for 2004)Quote from: SeanB on September 27, 2015, 12:23:29 pmOf course it will be just as much of a room heater, probably even a more efficient one, with a fan to distribute the heat.I'm slightly suspicious of the 55555 hour run time - a bit too "neat" and only, if fact, 330 weeks or just over 6 years 4 months.I wonder if it stopped incrementing the runtime when it hit that count.

content: Quote from: PA0PBZ on September 27, 2015, 05:37:06 pmYeah but 55555. That must be like winning the lottery with 1,2,3,4,5,6 as the numbers. I mean what are the odds on that?

content: After a little thrashing of it gently it still is happy, and now has 55565 hours on it. Been using it as a scratch disk, copying ( slowly using a USB dongle) 120G of data to it. now to copy it back to null and see if it has kittens.

content: Quote from: SNGLinks on September 28, 2015, 10:02:09 amYes, but most people don't think like that. If they did they probably wouldn't bother doing the lottery. There are some people who think they are being clever by deliberately sticking to 1,2,3,4,5,6 just to wind people up (in their syndicate for example). It's actually foolish to do that because there are many likeminded people doing the same. So if the numbers ever do win then the prize will be shared by 100's, 1000's evenWhen I was cajoled into a workplace lottery syndicate I considered it, but then decided to choose numbers over 31 instead as so many people choose birthdays for their numbers and I've enough people in the syndicate to share £20,000,000 with as it is
