If this is the case, yes - RMA or replace the drive. I'd be willing to bet that a look at the "health" tab will show your Reallocated Sectors count is either in the yellow or the red. Windows provides no tools that can display all this data, but something like HDTune can surface this information. The hard drive keeps a count of how many reallocated sectors it's used up. If there are bad sectors, they will be encountered and reallocated from the reserve at this time. One of the functions of a disk format is to mark bad sectors as unusable, but how does this interplay with the reserve sectors mentioned above?īy doing a full (non-quick) format, you force the drive to touch every sector on the disk. When a physical defect on the disk surface is encountered, the drive will silently mark that specific area as unusable and instead write the incoming data to a reserve sector it keeps unused for precisely this occasion. The short version is that modern hard drives tend to not show their bad sectors anymore. What should I do now? Should I still keep using it because it seems to be fine now or should I RMA it and get a repaired/refurbished drive since it is still under warranty? In addition, I used to not be able read the drive at all and it would cause windows disk management, file explorer and sometimes it would cause the bios to hang on my computer. I tested the drive with different software other than seatools to get a second opinion and it passed those tests too. Now the drive somehow can pass any tests I throw at it. All of a sudden after I deleted all the partitions on the drive and reformatted the drive after backing up the data on the drive. When I try to run fix-all fast and fix-all long on the drive to try and fix the bad sectors it fails. I ran these tests from two different computers both from inside Windows 7 and Windows 10 and using sea tool for dos. I could access the data on the drive without any problems. It would however to pass the short generic tests. You can also run CHKDSK /f /r /x in a Command Prompt for your Windows drive then you need to reboot for ChKDSK to run to check for bad sectors on your Windows drive. It will check and repair any bad sectors on your Windows drive. When it failed tests sea tools would warn me about having bad sectors. Seagate Seatools is faster than Seagate Seatools for Windows which is the only advantage to using the bootable version. The drive used to fail the short drive self-tests and the long generic test.
