On the current rawhide palipsest reports bad sectors on my hard disk. In details window two attributes fails. When I try smartctl -a or smartctl -l on the same disk, it reports no error. So, I do not know whom to believe. Maybe one remark. I tried to read DK-disks sources and to come up with a small test program. I found that sk_disk_smart_get_bad function (which I think is used to check for bad blocks) returns -1 on my disk. Similarly, sk_disk_smart_get_overall returns GOOD, which should mean no bad blocks. I attach the output of devkit-disks --show-info /dev/sda and of smartctl -a /dev/sda. devkit-disks --show-info /dev/sda Showing information for /org/freedesktop/DeviceKit/Disks/devices/sda native-path: /sys/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda device: 8:0 device-file: /dev/sda by-id: /dev/disk/by-id/ata-FUJITSU_MHY2120BH_K434T81257SL by-id: /dev/disk/by-id/scsi-SATA_FUJITSU_MHY2120_K434T81257SL by-path: /dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0 system internal: 1 removable: 0 has media: 1 detects change: 0 detection by polling: 0 detection inhibitable: 0 detection inhibited: 0 is read only: 0 is mounted: 0 mount paths: mounted by uid: 0 presentation name: presentation icon: size: 120034123776 block size: 512 job underway: no usage: type: version: uuid: label: partition table: scheme: mbr count: 9 drive: vendor: ATA model: FUJITSU MHY2120B revision: 0084 serial: K434T81257SL ejectable: 0 require eject: 0 media: compat: interface: ata if speed: (unknown) ATA SMART: Updated at Čt 16. duben 2009, 16:14:00 CEST assessment: PASSED bad sectors: Yes attributes: One ore more attributes exceed threshold temperature: 41° C / 106° F powered on: 92 days offline data: never collected (487 second(s) to complete) self-test status: success or never (0% remaining) ext./short test: available conveyance test: available start test: available abort test: available short test: 2 minute(s) recommended polling time ext. test: 69 minute(s) recommended polling time conveyance test: 2 minute(s) recommended polling time =============================================================================== Attribute Current/Worst/Threshold Status Value Type Updates =============================================================================== raw-read-error-rate 100/100/ 46 good 173680 Prefail Online throughput-performance 100/100/ 30 good 0 Prefail Offline spin-up-time 100/100/ 25 good 1 msec Prefail Online start-stop-count 99/ 99/ 0 n/a 720 Old-age Online reallocated-sector-count 100/100/ 24 FAIL 8589934592000 sectors Prefail Online seek-error-rate 100/100/ 47 good 305 Prefail Online seek-time-performance 100/100/ 19 good 0 Prefail Offline power-on-hours 96/ 96/ 0 n/a 92 days Old-age Online spin-retry-count 100/100/ 20 good 0 Prefail Online power-cycle-count 100/100/ 0 n/a 634 Old-age Online power-off-retract-count 100/100/ 0 n/a 14 Old-age Online load-cycle-count 98/ 98/ 0 n/a 57867 Old-age Online temperature-celsius-2 100/100/ 0 n/a 41C / 106F Old-age Online hardware-ecc-recovered 100/100/ 0 n/a 29 Old-age Online reallocated-event-count 100/100/ 0 FAIL 459603968 sectors Old-age Online current-pending-sector 100/100/ 0 n/a 0 sectors Old-age Online offline-uncorrectable 100/100/ 0 n/a 0 sectors Old-age Offline udma-crc-error-count 200/253/ 0 n/a 0 Old-age Online multi-zone-error-rate 100/100/ 60 good 19949 Prefail Online run-out-cancel 100/100/ 0 n/a 1533207445856 Old-age Online head-flying-hours 200/200/ 0 n/a 0 msec Old-age Online ===== smartctl version 5.38 [x86_64-redhat-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: FUJITSU MHY2120BH Serial Number: K434T81257SL Firmware Version: 0084000D User Capacity: 120 034 123 776 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 3f Local Time is: Thu Apr 16 16:31:10 2009 CEST SMART support is: Available - device has SMART capability.

I think Lennart recently fixed a bug in libatasmart for this http://git.0pointer.de/?p=libatasmart.git;a=commitdiff;h=6afdd8b2c56c09ab6d20d8d53aeee5a2faec44e9 Reassigning to libatasmart since that's how we get this data.
Oh, and maybe I should note that the commit David mentioned does *not* fix the issue.
Jiri, could you please get me the raw SMART data from you drive? Please attach the file that 'skdump --save=mysmartdata /dev/sda' generates.
Created attachment 339917 [details] output of 'skdump --save=mysmartdata /dev/sda' Lennart, here are the raw SMART data.
*** Bug 496153 has been marked as a duplicate of this bug. ***
Fixed in 0.12-2. libatasmart should now parse your smart data correctly (verfied on the blob you supplied). Will hopefully enter f11 soon.
Thanks! I'll follow-up once I ge the update.
Awesome. Looks to be fixed.

David, your disk has 65541 reallocated sectors, so libatamsart is doing everything correctly.
Like David, I have a Hitachi notebook drive that has an apparently high Reallocated_Sector_Ct: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 5 Reallocated_Sector_Ct 0x0033 100 100 005 Pre-fail Always - 131092 The raw count (131092) seems very high. I get a desktop warning (from F11, libatasmart-0.12-3.fc11.x86_64) that my disk is about to fail. I'm not sure that this is accurate since the (cooked) value is 100, which is very good. I notice that 131092 in hex would be 20014. David's raw 65541 is 10005 in hex. So I wonder if the raw number is not a simple integer count of reallocated sectors. This suggests that the bottom 16-bits might be a separate counter from the rest of the number. This drive is: Model Family: Hitachi Travelstar 80GN family Device Model: IC25N060ATMR04-0
