How to recover deleted files from USB

USB (Universal Serial Bus) Flash drives have made our life on-the-go. USB drives are portable data storage devices which incorporate flash memory and an integrated USB interface. Some of the manufacturers allowed up to 10000 write/erase cycles, depending on the type of memory chip.USB devices had allowed us to transfer much faster, smaller in size and even it is immune to electromagnetic interference and are not hampered by surface scratches.

Although secure, the USB devices are subject to corruption of data or loss of data. Worried about how to recover deleted files from USB?

The software application that allows restoring deleted files from USB drive is Recover Windows which allows the user undelete file from USB, external as well as internal drive and memory cards (Transcend, SanDisk etc.).This software application is compatible to Windows and Mac respectively which is free to download throughout the web.

With the advancement of technology the USB had also transformed. The first USB device was with a storage capacity of 8 MB which was available from December 2000 and nowadays it had gradually doubled and as of now USB drives with a storage capacity of 512 GB and 1 TB which are less frequently available. The flash memory incorporates hardware designed EEPROM technology which can both read and write complex high voltage device circuit. There are five components that make up the complete USB device being:

  • Standard-A USB plug is responsible for providing a physical interface to the host
  • USB mass Storage Controller an advanced microcontroller with a small amount of RAM and ROM.
  • For storing data NAND flash memory chips are used.
  • The Crystal oscillator produces device’s main 12 MHz clock signal.
  • Cover which is typically made of plastic, metal etc for protection against mechanical damage.

If these are displayed on your screen the data is corrupted

  • Code 1 : This error code displayed when no drivers are installed on your computer
  • Code 9: This error code is displayed when the windows cannot identify this hardware as it does not have a valid hardware identification number.
  • Code 10: This error message is displayed when the “FailedReasonString” value string displays an error message defined by the hardware manufacturer.
  • Code 39: USB device is not working.
  • Virus and malwares can also cause files to disappear

The Recover Windows can repair data from RAID partitions (RAID0, RAID1 and RAID5), from files systems such as FAT16, FAT32, EXFAT, NTFS and NTFS and recovers from hard drives being SATA/SCSI/IDE etc.  The “Find” tool allows the user to find for the specific file by specifying the format, date, size, name etc and the “Preview” tool allows to view the recovered files even before the recovery process is over. The recovered files are listed in a ordered manner.

Ways to avoid error!

  • The USB device must be scanned regularly to prevent the device from infliction of Virus and malwares. Transfer of data should be done between secure and protected systems.
  • Eject the USB device according to the system procedure and do not disconnect the device unless the recovery process is complete.
