Data recovery from flash drive can be performed with the help of software and hardware tools meant for mobile devices, smart phones and tablets. Flash drives are also extensively used in USB connections to laptops and desktop systems as external storage devices. Before trying to understand the data recovery processes from these types of drives, you need to know about their architecture, file system and associated mechanical and electronic components. Most of the flash memory cards attached to mobile and smart phone devices have an electronic PCB on to which the storage devices are mounted. Mobile devices boot their OS through the root sectors in the drive and software tools get loaded into the internal memory unit from the flash drive when the mobile is working. In case of smart phones and tablets working with flash drive, the storage drive is almost similar to the USB based external drive, with tracks, sectors and a read-write head assembly, though it is not an exact replica in its architecture compared to fixed drives.
Flash drive bugs
Most of the logical bugs from USB flash drives occur in the form of unintentionally deleted files, formatting errors, file system crash, root sector failure etc. Software utilities which you download from internet for fixing such bugs need to be compatible with the OS, file system and hardware architecture of the flash drive and electronic PCB on which the drive is embedded. The site from which you plan to download the software will give you most of the information related to compatibility parameters.
Best practice recommended for you when you have significant data recovery in hand is to take the help of professionals who have access to sophisticated hardware tools and OEM & enterprise standard software utilities for data recovery. They will be able to provide detailed scanning, accurate error listing and precise options for salvaging data from critically crippled flash drive devices.
Our established infrastructure of genuine data recovery hardware apparatus and OEM & enterprise standard software utilities along with qualified and experienced technical team ensures flawless bitwise data recovery from flash cards and USB flash drives.
File deletion: – Unintentional file deletion can happen when you are using mobile and smart phones connected to flash drives, especially when the user interface happens through touch-screen. Deleted files are not literally removed from the file allocation tables in the flash drive unless these sectors are overwritten by other files. Undelete option in the data recovery software will be able to restore most of the deleted files even after a gap of few months. You need to connect the flash drive with the main computer in which the recovery software is loaded. Then you can run the application and select the undelete option from the user interface menu. The system will prompt you to select the drive from which the deleted files have to be salvaged. Once it is done the system proceeds to list out the files from the deleted archive and prompts you to choose files for recovery. You may select only a few or all of them by ticking on the check-box to the left of deleted files. All those files are actively restored within the next few minutes by the software application.
Drive formatting: – It is not uncommon for you as a novice flash drive user to accidentally format it. If you happen to format the primary partition from an external system like a computer, the OS will also get deleted from the system and it won’t be able to boot when you connect it to the mobile or smart phone device. In such a case you need to recover files from the formatted partition by connecting it to the desktop computer once again.
When you run the data recovery software application like the one from ICARE, you will be able to see three options in the main menu for deleted files, deep scan and lost partition recovery. You need to select the deep scan option and choose the formatted partition drive name. The system will scan and list out all the deleted files from this part. You can select single or multiple files and restore them by clicking on the Save Files option.
Note: – Once you are aware a specific the flash drive partition has been formatted, don’t try to save any files or cerate folders in this partition as it may overwrite the deleted files permanently. Even physical damages to the flash drive can render the files non recoverable forever.
File system crash: – Flash drives work on FAT-16/32, HFS/HFS+, HPFS and NTFS formats. File system can crash when the partition or data structure table gets deleted or corrupt. It can happen due to accidental dropping of the mobile device, smart phone or tablet. Virus attacks can also corrupt the file systems. When the OS crashes unexpectedly also the file system can get damaged. In such cases the corrupt partition will have a RAW file system, making it impossible to access any data from that partition. OEM and enterprise level software application used by data recovery professionals can recover the file system completely from scratch and restore them to original conditions. It will also enable you to restore all the files from the partition and salvage them onto another external drive.
Partition deletion: – Logical partitions may get deleted by accident when you are working with flash drives on mobile and smart phones. In such cases the system will show only the physical partition and the data within that. Access to the deleted partition and data will be lost. The data recovery software applications have options for partition undelete and data recovery from such partitions.
Hardware issues: – Most of the hardware issues in the flash drives come from electrical or electronic component failure. The data recovery expert will be able fix the bugs with Flash ROM scanning and debugging tools, which also have built in OEM software applications for data recovery after hardware bug fixing. It is always better to restore the files from the hardware failed flash drive onto a working drive.
