Note that the block numbers in the bad block list must be generated using the same block size as used by mke2fs. If this option is specified twice, then a slower read write test is used instead of a fast read-only test. For example mkfs.ext4 has these parameters:Ĭheck the device for bad blocks before creating the file system. You can also pass a list of bad blocks when you format the disk (partition). Yes, if you're willing to take the risk of losing your data. If not the above, can I just create partitions before and after the part of the drive with the bad LBAs? After moving them, you could allocate a logical volume (LV) on the affected PEs to make sure they don't get used again. If you're willing to take the risk of losing your data, you can try moving the affected physical extents (PEs) with pvmove, but figuring out which PEs correspond to the bad sectors is going to take some grunt work. ![]() If not, since I'm using LVM on top of RAID, is there a way to tell either of these to just skip the bad area? Also some of them manage to relocate (remap) the bad sectors when you write to them again, but in your case it seems it didn't work. By the way, most drives happily write the data without checking that it was really written correctly, which can lead to silent data corruption. Seatools said it has some bad sectors, so obviously you can't use the whole drive. ![]() ![]() When running certain scans, a dialog box will appear asking if you would like to perform block-level repairs on your Seagate drives.If the zero fill succeeded, and the short test passed, can I still use the whole drive? One very important one to consider is the ability to attempt fixes on drives found to be failing. If you are testing a Seagate hard drive, you will have additional options available in the SeaTools menus. This is a great tool for IT consultants as well, it gives a simple and concise Pass/Fail for hard drives that can be shown to customers if they have concerns. Some malfunctioning drives will pass the “short generic” scan but will fail the “long generic” scan depending on where the faults lie and if the malfunctions present themselves spontaneously or if they’re a constant problem. Typically, I will run a short scan before attempting hard drive recovery and a long scan after an initial recovery sweep. The “Long Generic” and “Short Generic” scans can be performed on any hard drive, regardless of manufacturer, and are extremely powerful in finding hardware issues with your drives. If you check the box all the way to the left of the drive you want to run a scan on, additional options such as the “generic” scans will appear in the drop down menus. These can be (P)ATA, SATA, SCSI, or USB drives. SeaTools is a free utility provided by Seagate and can be downloaded from the Seagate Website.Īfter loading the Seagate SeaTools software, you will see a list of hard drives that your computer has detected. data, but it’s hard to beat a utility made by one of the largest hard drive manufacturers, Seagate (I mean, c’mon, who knows hard drives better than those that create them). If you believe your computer may be experiencing hard drive failure or if you would just like to make sure the hard drive you use to store all of your data currently is in good shape, you should test your hard drive for errors! There are many free utilities out there that perform some basic tests or read the S.M.A.R.T.
