If you are testingevaluating a questionable driveused or evaluating used drivesquestionable hard drive, this guide will show you how to do basic hard drive testing. Most'''While these tests are not perfect, most drive problems will be exposed during these tests.''' | | | Many common drive problems include: | * High hours (wearWear and tear) | | * Hidden problems | | * Reallocated sectors | | * Pending reallocated sectors | | === Why should used hard drives be checked? === | '''Most failures are sudden.''' CatchingIf these problems are caught early may prevent a, the drive failurecan be replaced before it fails. SMART plays a major role in this, since the data can be used to check for logs and failure patterns. | | | '''Note:''' Some hard drives (Ex: Seagate 7.01/7200.11) are known to fail. Others fail due to lower quality standards (Ex: WD Blue/Green). | | === Guide notes === | | * '''While Parted Magic can legally be redistributed per the GPL, I will not point to these downloads.''' | * '''The tests used in this guide may not detect all drive issues. It isare not 100% accurate.''' | | === A word on drive remapping === | * '''While [https://support.wdc.com/downloads.aspx?p=2|WD], [https://www.hgst.com/support/hard-drive-support/downloads|HGST] and [https://www.seagate.com/support/downloads/seatools/|Seagate] offer diagnostic tools, these willdo not work in every scenario (Ex: Lots of bad sectors).''' | | * '''Before attempting a sector remap, backup your data.''' | * '''If the drive hasDrives with SMART errors, replace it should be replaced.''' |
