USB flash drives, better known as pen drive are very handy storage devices. When you plug the flash drive in the USB port, it detects it as a removable drive and assigns a drive letter to it. Although these low power consuming drives are quite popular as these are cheap and small but corruption leaves nothing in the world of computers. Corruption of USBs might occur due to virus infections, human errors, power outages, damaged operating system etc. During such conditions, you should consider using a third party data recovery software.

Consider a situation when you have a flash drive comprising of important documents, photos etc. When you insert it after using it on another system, you come across the following error message:

“Disk/drive is not formatted. Do you want to format it?”

Now you decide to format the flash drive so that you can get access to your flash drive again. Since you have important data in your pen drive, you don’t want to format your USB drive. If it had been a hard disk, then this condition could have led you towards an accidental deletion of partition. It is quite possible that the issue is with USB port and not the drive itself.

In order to resolve this issue of USB port, try to connect the flash drive to the motherboard. You see it might just work that ways as at times, wiring between the motherboard USB header and ports does not works properly with the USB drives. But if this doesn’t works too, then use Kernel for Windows partition recovery software to recover your important data. This tool is powerful and reliable and is integrated with algorithms especially to recover data that becomes inaccessible due to various corruption issues.

At times when you start your computer, it may not start successfully due to particular boot up process related issues. When you use fixboot command to solve the boot issues, it might change your file system from NTFS to FAT and might make your entire hard drive partitions and data inaccessible. Such behavior causes partition loss and you need to opt for partition recovery solutions to recover the inaccessible or lost data. In a practical scenario, when you try booting your Windows XP Professional computer, the process might halt with the following error message:

“We apologize for the inconvenience, but windows did not start successfully.”

With this error message, Windows prompts you to boot the system in Normal mode, Safe Mode with Command Prompt and Safe Mode with Networking. When you attach the affected hard drive to another system as a slave, which had Windows installed, the system will assign drive letter to the hard drive. But when you try to access the drive, Windows gives you an error message:

“The disk is not formatted; do you wish to format it now?”

After this error message, when you attach the hard drive with other PC and try to install new operating system using “Leave the current file system intact (No Changes)” option, the process fails because the partition is listed as:

“Partition 1 (Unknown)”

After this behavior, when you use Recovery Console and use CHKDSK command to detect and fix file system problems, you might encounter the following error message:

“The volume appears to contain one or more unrecoverable problems.”

When you try fixboot command to resolve the boot issue, it comes up with the following message:

• “FixBoot is attempting to detect the file system type.
• The boot sector is corrupt
• FixBoot is checking the file system type
• The partition is using the FAT file system
• FixBoot is writing a new boot sector
• The new boot sector was successfully written”

After this process, the system boots properly but your NTFS partitions become FAT 32 and data stored on them becomes inaccessible. All you can do to recover data is use partition recovery software and scan the physical drive to recover all NTFS partition. These recovery software are specifically designed to scan the entire hard drive thoroughly and achieve quick and proficient data recovery.
