If you use digital cameras, or any other device that uses Flash cards for storage, you should always have a program like CardTest on hand. If you don't have it, sooner or later that dreaded moment will come when you lose data and have no way of recovering it.
CardTest is a utility that allows you to check and recover bad sectors of the flash card memory of digital cameras (or any other device). These cards, like any hard drive or storage device, can be corrupted. When a sector is defective, the card may stop working and it will be impossible to access it. And we are sure that it will not be funny to throw a card and give up everything you have stored in it only for a broken sector, right?
CardTest can check and recover Flash cards of any type: CF, SD, XD, MMC, and others. To do this, keep in mind that you will need to have a card reader at hand, or unless your PC has this option. In addition, CardTest is capable of scanning RAW file systems and recover lost JPEG images. Very useful, and it is also free and does not take up much space on the hard disk so ... we recommend that you have it on hand just in case.
You can free download CardTest 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
