When Do You Need an SD Card Repair Tool?

Generally, you need an SD card repair tool when your memory card gets corrupted. An SD card can be corrupted in various ways. You can divide this corruption into two categories: logical corruption and physical corruption. If your SanDisk SD card is physically damaged, no repair tool will help and only manual repair services should be applied. If your memory card is logically corrupted, see if your SD card fits one of the following situations:

• The SD card shows no files, but there are files on it
• The memory card shows the RAW file system
• The SD card shows "Missing", "No Media" or other states in Disk Management

Of course, there are other situations in which your SD card is inaccessible. But, these are the most common situations in which you need an SD card repair tool to fix your corrupted SD card. An SD card repair tool is able to repair logical corruptions like file system errors, wrong formatting, reading errors, and more. However, since some SD card repair tools work to fix a corrupted SD card by restoring your flash drive to its factory default settings, there will be data loss after the repair. In this case, you will need to first back up your data before using the repair tool.

If the files on your SD card are still available, you can copy the files and folders from it to somewhere else to make a backup. However, in most cases, when your SD card gets corrupted, you cannot open and access the files on the device. This is when you need the SD card recovery software - EaseUS Data Recovery Wizard to recover your data before the repair. It will easily recover data from a detectable but inaccessible SD card, be it from SanDisk, Toshiba, Sony, Kingston, or other brands.
