A USB flash drive is a removable and rewritable storage media. The data stored in USB flash drive is less susceptible to loss than a floppy disk.
However, like other storage media, such as hard disk, USB flash drive can also be encountered with data loss due to the following reasons:
- Accidental files deletion from USB flash drive
- Malicious virus infection
- Accidental formatting of USB flash drive
- Corruption of USB flash drive
- Power surges
- Application Failure
- Physical Damage
- Other Unknown Reasons
Due to any of the reasons mentioned above, you can lose your valuable data. Therefore, it is always suggested to maintain a backup of the data stored in USB flash drive on other storage media. Most of the cases can be solved with the help of manual or automated methods, but to recover data from a physically damaged hard drive is nearly impossible. That’s why taking precautions is always recommended.
When a USB flash drive is corrupted, your computer system finds it unable to read the data stored on it and displays the message; ‘Drive could not read. Needs formatting.’ After reading the message, most of the users format the USB flash drive, which results in data loss.
On the other hand, sometimes, when you attach the USB flash drive to your system, anti-virus/anti-spyware installed on your system marks some files suspicious if they contain any information that can harm your computer system. At that time, anti-virus/anti-spyware prompts to quarantine/remove the file, which also results in the data loss.
Whatever is the reason for data loss whether virus infection, accidental deletion, or formatting, you can easily recover the lost data. The files removed from USB flash drive are actually not deleted but just marked as deleted because of which you cannot view them. Until the files marked as deleted will not be over-written by other files, you can recover lost data from USB flash drive with little efforts.
