macOS – What Does ‘Initialize’ Mean for a Micro-SD Card?

macsd card

The micro-sd card is used as the storage of my dashcam. It works fine before. But today when I connected it to my Mac, as usual, there is a popup saying:

enter image description here

It seems my sd-card has broken. But what does "Initialize…" meaning? If I click it, what would happen?

Will I lose all my data?

Thanks,

'Initialize' means 'Format'

The ellipsis … following it is standard 'computer speak' for "this won't happen before you see some more options."

So, for whatever reason, your computer cannot read the existing format on the card & wants to attempt to erase & start afresh. That would lose all data already on the card.

Re-test it in your dashcam, but be prepared to bin it & buy a new one. They're really fragile structures & easily fail. You could try data recovery software if the data is valuable.

It would also be worth removing & reinserting the card & rebooting the Mac, just in case it was a one-off glitch, dirty contacts, etc.
