Please don't use a front-end for this request -- I'd like to see the full, verbose output. I can help from that point going forward. (Wow, I sound like a CSR or something...) And no, you cannot reset data stored in SMART. The only data that's possible to reset -- and only on very specific models of specific vendor drives -- is the SMART error log. -- Making life hard for others since 1977.

And no, you cannot reset data stored in SMART. The only data that's possible to reset -- and only on very specific models of specific vendor drives -- is the SMART error log. Upon a second look, it appears that the number of sectors that have been reallocated would make up a 4 PB (4,000 TB) hard drive, when my drive is only 160 GB! I just assumed the number would match the sector count of the entire drive, since it was so large, and should technically be at 0.

If Selective self-test is pending on power-up, resume after 0 minute delay. I ran all 3 tests, and they all passed. Even the "Reallocated Sector Count" claims to have no issues, which contradicts the raw value of 8589934592000. GSmartControl says "NOTICE: This drive has a non-zero raw value, but there is no SMART warning yet. This could be an indication of future failures and/or potential data loss in bad sectors." Here is where another problem lies. If I am to accept that this is just a glitch in the calculation, and that I do not have any bad/reallocated sectors, then what about in the future? How would I ever be able to use smartctl to know when my drive has reallocated some bad sectors? (A sign that the drive is failing.) -- CampaignForLiberty.com Educate yourself.
