Full version of professional data recovery software tools can salvage any type of files from pen drive. Since most of the pen drives work with single partition, the fear of partition deletion or corruption is practically non-existent in these drives. The other issues could be related to file and folder deletion, corrupt file system, virus attacks and physical damages to the drive. Sometimes the files and sub folders within the pen drive may be just hidden by Trojan type of virus. In such cases you will not be able to access of these hidden files from windows OS. You need to open the DOS command prompt and change the attributes of hidden files and sub folders.
If you have used the computers during DOS era, you will be familiar with the attrib command. For this you need to open the command prompt window by typing in “CMD” at the run option of windows. Once the command prompt opens up you need to switch to the pen drive from default c:\ drive prompt. Just type the drive letter followed by: and \. If your pen drive letter is f, you can simply type in f:\ and press the <ENTER> key. Now you are taken to that drive.
Key in the command “ATTRIB –S –H /s/d *.*” and press the <Enter> key. It will unhide all the hidden files (*.*) and sun folders (/s/d) even if they are empty. –H is used for removing the hidden attribute and –S is used for including system files. If you wish to exclude the system files from being unhidden you can omit –S from the command.
When the pen drive gets affected by virus attack, they can corrupt or delete the files. You need to install and run powerful antivirus tool like MacAfee antivirus, Norton disk doctor or AVG antivirus to remove the virus completely from the pen drive. Before that you need to ensure that the computer hard drive from which you are running the antivirus application is free from virus. It can be ensured by getting the fixed drives scanned by the application and setting the virus removal into auto mode.
Corrupt file system restore
File system in the pen drive gets corrupt due to virus attacks and physical damages like bad sectors. If you are using windows 7 or higher versions of OS, you can try to fix the bad sectors in the pen drive after removing the virus.
- Type FDISK at the run command and press <ENTER> key.
- Disk management utility will be opened in a new window with detailed volume and disk information. This window will display file system type, disk space occupied by the partitions, their health condition and other related details.
- Select the pen drive letter from the “volume” section, right click on it and choose “properties”.
- Select the “tools” tab and you will be able to see three options in that for error checking, defragmentation and backup. Click on the “Check Now” button and you will be able to see another window for check disk.
- You can find two check boxes with options for automatically fixing file system errors and data recovery from bad sectors. Chen both the boxes and click on START.
This utility will scan the complete pen drive for file system errors and fix them, besides restoring data from bad sectors. Once the scanning and fixing is complete you can access all the files from the pen drive.
Most of the times you may not try to fix the physical damages suffered by pen drive apart from repairing and recovering bad sectors. It is because you may have a copy of the data in your fixed drive and hence you don’t bother about taking your pen drive to a data recovery expert for fixing hardware failures. But when you carry critical data in this device which may not be available otherwise, you will be forced to get it repaired by a hardware technician. Our cost effective services ensure complete salvaging of data from critically damaged pen drives and their restoration into another external drive which is in working condition.
Accidental fall: – When the pen drive falls off accidentally or hits hard surfaces, it may suffer internal hardware damages. In such cases data can only be recovered from the device by using hardware data extraction tools.
3-D data recovery is one form of extracting data from the pen drive. The procedure followed in this method is similar to that of FDD, but the repairing methods used for drive restoration could be slightly different, owing to the variation in the internal architecture of the drive.
The process consists of 3 stages, starts from Drive-restoration. Hardware tools are used restore the electronic components which are connected to the drive and its components. PCB ROM data is restored with the help of a donor board ROM which makes the connectivity with the pen drive possible. Other electronic components in the board and chip level are also replaced with the help of PCB card swapping tool.
In the second stage data is mirrored from the failed Pen drive onto a secondary storage medium. All the data from sectors get mirrored into the target disk.
In the third stage the technician uses OEM data recovery software application for regrouping and repairing files. It is always better to let the system perform a complete scan before fixing the files. Auto repair and data recovery tools provide best of solutions for maximum data recovery.
File systems in the pen drive could be FAT-16/32, NTFS, HFS/HFS+, HPFS or other format, depending on the OS in the main computer to which the pen drive is connected. The repair tool used by professional data recovery expert is able to provide compatibility for all file formats and extracts data to the bit level. However 100% data recovery in case of physically damaged drives cannot be guaranteed as the data tracks and sectors in the drive are highly sensitive in nature.
