We get all sorts of memory cards as donations.
Some of the more common types:
- Secure Digital (SD)
- MiniSD
- MicroSD
- CompactFlash (CF) I, II
- MemoryStick (MS), Pro, Duo
- MultiMediaCard (MMC)
- xD-Picture Card
- SmartMedia (SM)
How to erase memory cards:
- Find a card reader
- Plug card reader into system
- Open up a terminal
- Insert a memory card into the card reader
- Unmount memory card - sudo umount /media/*
- Identify where card is listed in /dev - dmesg|tail or dmesg|grep sd*
- Start badblocks - sudo badblocks -wvvf -c1024 /dev/sd[whatever this letter is]
- Wait until badblocks finishes
- Remove and label memory card (write OK on card with a sharpie)
- Store card in TARDIS
Things to be aware of:
- The more memory cards you have connected to a system, the trickier it
gets to tell them apart in dmesg
- The more memory cards you have connected to a system, the longer it'll
take to test and wipe them concurrently
- You may need to wait for all cards in a card reader to finish testing
and wiping before you can add cards to other card
