Have your USB drives become corrupt or deleted your files or formatted your USB Pen drives accidentally without knowing and thought that all the files in the drive are gone forever.But in the actual case the file is still alive and it’s recoverable only if the disk hasn’t been overwritten.Only the pointer to that file is being actually deleted and the windows thinks that there is an empty space and writes over them.When a file is deleted, it is removed from the file system. However, the actual data is not erased.Sometimes after unsafe eject of your USB drives it might show that “Drive not formatted.Format it now”.Doing so will destroy all your data that moment itself and you are forced to recover that deleted files.
According to Lexar tech support, there is a bug with Windows 2000 (that MS never bothered to fix) and can corrupt the drive when it is removed without proper eject. They recommend EasyRecovery Pro for data recovery which did allow me to recover some files (> 500) using their RAW data recovery program (all other tool failed because usually said “no recognizable file on disc”).
