In this page, we discuss what is RAW partition, why a partition becomes RAW file system as well as how to recover files from RAW drives on hard disk, external hard disk, USB flash drive, etc.
What is RAW partition?
Windows allows users to divide computer hard drive into several divisions for efficiently managing files and improving performance. And these various divisions are called partitions which should be formatted before storing files and folders. Partitions under Windows usually adopt NTFS and FAT file system, which may become RAW if file system is damaged or corrupted. In such situation, users cannot access the partition and files in the partition. If you do not have a recent backup of the partition, then RAW drive recovery should be performed as soon as possible. RAW partition can be accessed and reports errors when you trying to open it, and here lists some error messages:
“You need to format the drive before you can use it. Do you want to format it now?”
“The disk in drive F is not formatted. Do you want to format it now?”
“E:\ is not accessible. The file or directory is corrupted and unreadable.”
Meanwhile, the partition shows as RAW in Disk Management, and the command chkdsk cannot be conducted.
Reasons of RAW drive and partition
The role of file system is organizing data on hard drive and telling operating system detailed information about each file, for instance, file size, type, name, beginning and ending sectors taken by files, etc., so that operating system can locate and access partitions and files.
When file system gets damaged, Windows cannot visit the partition or files, and uses cannot open the partition either. Since RAW is a kind of error of file system, partition that turns out to be RAW is no longer accessible.
Many causes can lead to a RAW partition, such as virus, improper ejection of USB disk, corrupted partition table, bad sectors, sudden power failure, etc.
