I have been getting a lot of computers in within the last week with disks that have bad sectors.

To test for that, I frequently use the gnome-disks tool from a liveboot of #LinuxMint.

Note that it says "Disk is OK" but then goes on to say that there are 4312 bad sectors.

If there are any bad sectors, the disk should be replaced. #Microsoft #Windows will start to choke, slow down and give errors even if there is only one bad sector.

Linux is a little more tolerant of bad sectors, but I still recommend replacing the drive if you rely on that machine at all.
