Hello :) I've got an issue with drive - current "current pending sectors" count is equal 15. I think that it might be only a result of a broken sata cable, which I've got rid of today. Long story short - drive was attached to faulty cable and sectors become counting. After adding another disk cable was swichted to another disk and the 2nd good disk started to become missing in disk manager and finally volume become broken. I've ended with 2 "faulty drives" in 3x 4Tb raid5 volume and tried to repair my raid. Finally it started to repair, but it became clear that disk with pending sectors was choosed by windows to use as one of two source drives... 3rd drive with good smart was cleared from raid nad dynamic drive at all
But, despites my afraid, whole volume resynched without any issue within a few hours with speed of 200mb/s read from both drives (including that with pending sectors) and write of 200mb/s to new drive.Smart in that faulty by smart mesures is the same as before, 15 pending sectors, not even one relocated, doesn't that means, there when it was rebuilding it was already fully readen and should easily get clean smart after zerofilling? By my expirience, when I've got job with access to many defected drives, which I have repaired from such pending sectors conditions and could simply get them for free, I've tried many times with many successes and long working disks,so i'm quite sure that indicator is result of that faulty sata cable :)
But there is a question - is it possible to somehow get rid of those sectors by for example chkdsk /r /f ? or is it another way? I don't want to be forced to connect yet another disk, unplug that "faulty", resynch again, zerofill drive and again unplug that 4th drive and another resynch... I don't want to do so mainly because my 4th drive is 6tb 5200rpm with 23k hours, and all 3 of my 4Tb drives are matching size and, what is even more important, they're 7200 with around 7k hours. And even, when i'll get rid of those sectors I'll have to resync volume to that 4tb which was missing few times, but has clear smart, but with method to clear them without zero-filling i'm way closer to desired state of 3x same 4tb as before got issues with that cable :)
