I've never had any drive report anything other than completion even when the drive had known bad sectors. There was no status of anykind, the hdparm command has no progress reporting at all, so it just seems to hang, and then it returns. And for drives with bad sectors, they were still bad sectors after ATA Secure Erase suggesting that while they're zero'd the firmware does no confirmation read and as such isn't checking for persistent write problems for the purpose of sector remapping. It's pretty much just a fast way to zero out a drive. To ascertain bad sectors and cause them to be remapped means using dd or badblocks with the proper blocksize (a multiple of 4096 bytes). -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
