: Yes and no. Delete may have a recovery option.
: However, formatting a drive with flash memory offers no protection
: that I know of, unless the information is cached (backed up) to a
: separate media.
I presume that your talking about a USB key, and not a HD that has a flash
memory cache, right?
: The reason is that flash memory is either there or it isn't, as
: determined by chip/connection logic.
I would have thought with that element to flash memory that there
isn't/wouldn't/shouldn't be a "ghost" image of the
data that had been stored there.
: However, on a normal hard drive or floppy disc with platters, there is
: a magnetic resonance that is left behind, so even if the electrons are
: scrambled, it is possible to still retrieve that information.
Yep, and depending on how badly someone wanted said data it is "always"
: So this leads to a side question: How to keep others from retrieving
: information from one of those media varieties?
: Answer: There are two ways: 1. Destroy the media. 2. Overwrite the
: media with garbage (Although this won't utterly completely keep
: someone from retrieving the information....whoever wanted it would
: have to pay dearly).
How many times of overwriting would it take to decrease the chances of it being
: I am not aware of any tools that do data retrieval from a flash drive
: unless it is being copied to another location...so if anyone knows of
: anything different, let me know.
