The problem with your new WD Blue 1TB SSD that won’t format or mount could be related to several devices, from hardware issues to improper disk organization. Here are some steps to help you understand the situation and possibly get your drive back up and running. 1.Checking the basic connection and power 2. Checking the disk visibility in the system Open the terminal and run: lsblk See if the disk is displayed as /dev/sdX (where X is the drive letter). If the disk is not displayed, the problem is either in the hardware or in the USB interface. 3. Plug in the disk and immediately run: dmesg | tail -n 30 This will show the last kernel messages related to the disk plug-in. If there are any errors or timeouts, this is an important diagnostic sign. 4. Using fdisk or parted If the disk is visible in lsblk as /dev/sdX, sudo fdisk -l /dev/sdX and sudo parted /dev/sdX print If the commands do not respond or give errors, this also indicates problems with the disk. 5. If the drive is not visible or constantly “freezes” Perhaps the USB-SATA adapter or the drive case is faulty. Sometimes USB ports on laptops provide little power - try connecting to a port with a higher power supply or through an active USB hub with power. If possible, remove the drive from the case and connect it directly to SATA in another PC. 6. If you have access to Windows, check the disk in programs such as Victoria HDD/SSD, CrystalDiskInfo If the disk does not appear in the system at all, it is most likely a hardware failure. If the disk is visible but not formatted, you can try “wipefs” and creating a new partition table. If nothing helps, and the disk is new, we recommend contacting the WD warranty service.
