Memory Cards

We get all sorts of memory cards as donations.

How to erase memory cards:

1. Find a card reader
2. Plug card reader into system
3. Open up a terminal
4. Insert a memory card into the card reader
5. Unmount memory card - sudo umount /media/*
6. Identify where card is listed in /dev - dmesg|tail or dmesg|grep sd*
7. Start badblocks - sudo badblocks -wvvf -c1024 /dev/sd[whatever this letter is]
8. Wait until badblocks finishes
9. Remove and label memory card (write OK on card with a sharpie)
10. 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
