If you do not see any sectors listed the in any of 4 passes it is highly likely that the drive is operating fine. It will repeat this 3 more times for the total of 4 passes. The badblocks 4 pass read / write test will write a pattern to every sector of the drive then read it back and report (by listing the sector #) every time the data does not match what the drive wrote. Still in this case I would look at the serial number. A second method to simplify the identification would be to pull out the SATA cable on all drives but the one to test. It will happily overwrite any drive you tell it. Make sure that you are absolutely certain because badblocks will not check if you have data or prompt.
I pretty much do the same even on systems that I have 20 hard drives in.Īnyways now you should have identified the drive to test. To print the serial number and other drive info that can be used for identification. Here is an example of a badblocks 4 pass read / write test: One example was years ago I used this method on brand new Samsung F4 2TB drives to find out there was a problem with these drives retaining data that we eventually found out was caused by a firmware bug. I actually do the same test for new drives or drives back from RMA since there is a chance of getting a DOA drive in these cases as well. I normally do at least a 4 pass read write test on each drive that I want to verify it is working. This is a program that executes in a shell booted off of a linux live usb stick like sysrescuecd. I normally test drives with a program called badblocks. At work have seen dozens of drives where when they go bad each full write of the disk the drive is not able to read back dozens of sectors it just wrote making it useless for data storage because it can not be trusted. I asked you about the drive being empty because its best now to test the drive to see if it is retaining data correctly or if there is a serious problem with the heads. There are spare sectors that will be used after the bad sectors are either overwritten or recovered.
