Then, let's see what could cause an SD card or other external drives become RAW format.

Possible Causes for SD Card or External Drive Turned into RAW

When Windows is unable to read or mistakenly read any of these 3 places, Partition Table, Partition Boot Sector, and File System, it will report the corresponding partition as RAW though all data are still saved there, which is largely because these places store the information of partition.

When partition table, partition boot sector, and file system get corrupted or damaged, Windows can't read them correctly, and the following issues may damage these parts:

• Unplug the drive from a computer without using the 'Safely Remove Hardware' option.
• Power outage or surge appears when external drive is working.
• The SD card or other external devices are attacked by virus. There are viruses aimed at damaging boot sector and MBR.
• Wrong or mistaken partitioning.
• Use inferior partitioning software.
• Your external drive has been physically damaged.

Nevertheless, there are situations where partition table, partition boot sector, and file system are intact but your SD card or external drive is also shown as RAW in Disk Management and Windows asks you to format it before you can use it. Under these situations, the RAW SD card issue might be generated due to malfunctioning card reader/card slot, improper device driver, etc.

Now, you must be clear to possible causes for SD card or external drive turned into RAW, so let's see the next part.

How to Prevent SD Card or Other Device from Becoming RAW

It's not enough to know how to convert a RAW SD card to FAT32 or NTFS, and the issue how to prevent this issue from happening again is also important.

• Firstly, insert and take out external drive using the correct way. To be specific, don't forcibly plug and unplug your SD card or other external drives, and disconnect it using 'Safely Remove Hardware and Eject Media' feature.
• Secondly, don't visit unsafe website and scan computer for virus periodically.
• Thirdly, use well known partitioning software to partition your SD card or external drive, and MiniTool Partition Wizard Free Edition, which enjoys about 20 million downloads, is worth trying.
• At last, always backup important files with MiniTool ShadowMaker, the best backup free software for Windows 10/8/7, which is the fastest way to repair RAW SD card.
