How to Format SD Card on Mac without Losing Data?

无论你部y a new SD card or want to change the file system of the card, or the data stored on the card is no longer needed, formatting is the way forward. You may also need to format the card even when the SD card is inaccessible or corrupted, incompatible with the device used, low in storage space, etc.

Formatting the SD card on Mac wipes the data stored on it, so you need to back up your SD card data before formatting to avoid losing your precious files. But how do you back up data from an inaccessible or corrupt SD card? For that, you’ll need help of a photo recovery tool.

Here, we’ll discuss how to recover your photos, videos, and other media files from both accessible and inaccessible SD cards, and then format them using Disk Utility or Terminal on Mac.
