Using hdparm --make-bad-sector to simulate read error.But I did not find way of simulating write-error. I tested md-faulty module, it can do this.But it is not provide the function link hdparm --make-bad-sector,which did not set lba. Using hdpamr --make-bad-sector to simulate read error can cause some problem. It will cause ata commnd reset,disk reset and so on.It take too log time. So I think add a function in md-faulty which can set read/write lba. How about ? -------------- kedacomkernel 2012-05-14
