Check your file system for logical and physical errors. Right-click on the drive letter in File Explorer, Properties, then Tools, Error Checking - Check or use the PowerShell:
chkdsk c: /f /r /x # /f fixes errors on the disk. /r locates bad sectors and recovers readable information. /x Forces the volume to dismount first, if necessary.
Windows will complain that the drive is locked. It will ask you to execute ScanDisk on next reboot.
Check your hard drives on MacOS. Launch Disk Utility (/Applications/Utilities), select the hard drive from the left side menu (e.g., Macintosh HD), and smash the Fist Aid tab.
diskutil list # List your disks. diskutil verifyDisk /dev/yourDisk # Verify the partition map layout of a disk intended for booting or data use on a Macintosh diskutil repairDisk /dev/yourDisk # Repair the partition map layout of a disk intended for booting or data use on a Macintosh
sudo apt install smartmontools # Install the smartmontools package for your system. If you are an Arch user, sudo pacman -S smartmontools. lsblk # List your hard drives. sudo smartctl -a /dev/sda # Check the health of your device
