New page

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
