Many of us have encountered file inaccessibility issue once or twice, by an error message "X:\is not accessible. The file or directory is corrupted and unreadable", or with another form of warning "you need to format the disk in drive X: before you can use it. Do you want to format it?" As we clearly know that when such an error arises, the direct result is then file loss if we choose to format or reformat the drive under Windows operating system.
Is there a possible way to maintain data and files while trying to repair "the file or directory is corrupted and unreadable"? In certain cases, the answer is positive. At this moment, by clicking the hard drive's property, you'll soon find that the drive has become RAW instead of showing in correct file system like NTFS or FAT32. Next, let's see how to repair RAW disk and recover files in all posibility.
When a hard drive, external USB flash drive, pen drive, extenal HDD or SSD or memory SD card is showing in RAW file system, it makes Windows misinterpret the storage device is just manufactured and has not been formatted yet. So it's unusable right now. In this case, all the contents on the drive can not be reached unless you fixed it to normal, or take advantage of the best data recovery software.
File system (NTFS, MFT, FAT) corruption, virus infection, bad sectors and abrupt removal of external USB are the main causes that lead to incapability of accessing to data there. You can fix the problem by running Chkdsk to check and repair file system error, or send the drive to professionals to remove bad sectors.
