sorry to be a pain but i doubt you'll get that tool by asking it here. I doubt that a public available tool that performs this function exists from intel.
i guess you're in the same boat as all of us. you'll just have to zero out the drive completely.
but i don't understand why you are worried about the zeroing out not writting data completely to the drives. true that SSD do come with spare sectors that get remapped in case a normal sector goes bad, but there is no reason to use these spare sectors unless an atual sector goes bad. (same with normal HDD, which have a grown defects list).
Just to clarify, "zeroing" an SSD drive certainly destroys data, but it does not necessarily clear (or attempt to clear) the bad sectors or any spare blocks. Also, using a data overwrite will never 'reset' the flash blocks so the firmware knows they are immediately available for overwrite (as opposed to executing the read/erase/write event for blocks which contain data already).
I ended up speaking with Intel and they recommended HDDerase, but they could not 1) guarantee it erases everything on the X25 and 2) they could not verify it would do the "SECURE ERASE" procedure specified in the ATA standards. I'll experiment with it and see if it can be accomplished, even if the system's BIOS ATA settings needs to be tweaked a little to succeed. If I learn anything, I'll update this thread.
Considering the Government and Military might be one of the largest users of flash drives initially, I find it very lazy on Intel's part not to supply this kind of utility to clear sensitive/classified data, especially should any SSD need to be RMA's for replacement. Who wants to send in a drive with potential sensitive data on it to an repair center?
To answer my own question, HDDErase does work and it works quickly on the X25-E drives. However, what Intel didn't mention before was that version 4.0 isn't compatible. HDDErase 3.3 is required, and the following page explains the situation in more detail:
So, for those of you looking for a secure erase (also helpful to remove pesky rootkits), this should help.
