Flash,
There are people who talk about problems and problems.
I want to be informed about the problem and know the solutions.
- This leads directly to the second major security issue afflicting SSDs:
secure deletion. Standard secure deletion software such as the Unix utility
shred is sufficient for secure deletion on modern HDDs, but largely
ineffective for consumer flash media storage devices.
This solution is mistaken. Shred doesn't work well when the data
won't stay still. This happens with our journaled format systems.
It it is an ext3, force mount the partition as ext2, then shred.
If you have sensitive data, copy the encrypted file to a RAM disk. Decrypt
it, use it, modify it or whatever, then encrypt it back to permanent
storage.
To wipe and restore an SSD
cfdisk /dev/foobar
note the partition structure, write down the CHS factory values
dd if=/dev/zero of=/dev/foobar
or
dd if=/dev/random of=/dev/foobar
cfdisk the device as it was from the factory
format the partition(s)
