Is your memory card really the size it claims?\n\nCounterfeit cards advertise a big capacity but really hold far less, then quietly corrupt whatever you save past their real size, right when you need those photos most. HearthCardCheck writes a verifiable pattern across the whole card and reads it back, so you know the truth before you trust it with your memories.\n\nWhat you get:\n- A clear verdict: genuine, or fake, and how much it really holds.\n- A health check: if the card is starting to wear out, you find out before you lose files.\n- Real speed: write and read speed, the speed class, and IOPS, so you know if it is right for 4K video and burst photos.\n- Repair a fake: turn it into a smaller, honest card you can actually trust, instead of throwing it out.\n- Works on SD cards, microSD cards, and USB flash drives.\n\nGood to know: to test the whole card honestly, the check erases it first. Back up anything you want to keep before you start.\n\nCompletely private: 100% local, no account, no telemetry, no cloud. Nothing about your card or your files ever leaves your computer.
