Today I faced serious issues about my laptop external SSD harddrive suddenly failed. oops I don’t have backup of recent data. We are tried to restore from windows automatic recovery and tried many method and also we used to remove the SSD and inserted again but still we have same issue and HDD not detected.
So We thought it SSD Failed and data gone. But luckily One of our IT support guy (named Rasheed) helped to recover data using with external drive like below image, the issue was that Laptop slot which is pointing to SSD hardrive insert.
Once we inserted the SSD Harddrive to external drive, the SDD drive detected.
