Secure erase SSD it get the speed back WITH Windows still installed

post #1 of 9
Thread Starter 
This is a method I have developed to secure erase your SSD and get the speed back like when windows was freshly installed. Only this is done WITH windows and all your programs still installed! It is non-destructive. A 64GB SSD will only take about 10 to 15 minutes for the whole operation. No more messing about uninstalling windows, erasing, then re-installing windows, or messing around with images! It’s a step by step guide, make sure you follow it to the letter so to speak, do not wipe windows by mistake! Make sure you select the correct partition to wipe and do not use this method unless you are certain of the procedure .

The procedure here starts with a pretty messed up C300 64GB SSD scoring a paltry 7.3 in WEI a few minutes later it's back to 7.9 and getting good benchmarks smile.gif Ive used it with good effect on other drives but had probs with the videos. It's also good this drive is so bad to start with...as it demonstrates how good this method is.

Ive put two short video tutorials on youtube and will follow up with text when ive had some sleep! Also the benchmark results....

That's pretty clever, now I'm thinking win7 is supposed to trim when it does a full format, I'm wondering if that would be enough on the new partition in disk management.

No it wouldnt be the same that would just mark files to be overwritten (or whatever it does) and not fully erase them. If I had stopped there I would have got 7.5 or 7.6 in WEI not 7.9

Well new at 11am when you've been up all night:) glad it stopped instead of paused as the 1st took 100 mins and the second 150 to upload lol

Parted magic

That's not a Secure Erase. That's just running TRIM commands across a large chunk of the drive.

With a Secure Erase, what happens is...
1) Erase command issued.
2) Every cell erased.

Then you restore a backup onto the SSD, and some percentage of NAND cells are filled with your OS and data. The rest are empty. (and in a large contiguous block)


What you're doing is...
1) Writing data across a large chunk of the drive.
2) Relying upon TRIM commands to signal the SSD to erase the data after it writes it.

This relies heavily on your OS supporting TRIM, or your SSD controller figuring out what's going on. Neither is foolproof.

Your method works, but it's definitely not as clean as doing an actual Secure Erase. (which should take about 30 seconds from start to finish, and leave all NAND cells in an erased state) If I were to analogize, yours is more like a HDD defrag. (which misses some Windows system files and NTFS crud, and doesn't have quite the same impact as a fresh Windows install)


Now, I have a question - since Windows 7 supports TRIM, could you skip the bootable stuff and simply run a CCleaner zero-pass over the new partition you create? That'd be truly time efficient. tongue.gif

CCleaner does not work the same ive tried it.

Ive put the tread to help people who dont want to go through all the hazzle of reinstall etc etc. Most SSD's now work on the internal erase command.

An actual secure erase yes, as you say takes about 30 seconds, and ADD all the imaging, uninstalling and reinstalling windows which is WHAT this post is about AVOIDING! Why remove windows when it's not needed.

The method works PT2 proves that from 7.3 to 7.9, if it didnt work the drive would have scored 7.7 not 7.9. if it dont work for someones particular drive no big deal just take aeons performing a secure erase....

Its worked for me on C300 64gbx2, + 128GB, Vertex 2's two of them, Vertex3 and Force sata3......

Thanks for confirming.

Must be something to do with Linux. I've noticed that a zero-fill in Linux triggers reallocating sectors on HDDs, so that zero fill must be doing something more than it seems to be.

Forgetting this actual method for a bit. If doing a proper secure erase with partedmagic using option 4 which will use the drives internal controller to do the erase. If the drive has been placed in a frozen state another option pops up before I new how to avoid the frozen state I would choose that. The drive would not then get tops in WEI.

There is something about that option 2 when applied to the free space partition adequately wipes it. As I say Ive tried many ways and its the best Ive found... The more modern drives have better GC now so secure erasing in any way wont be needed unless the drive is well caned, simply logging off here and there should suffice.


Ive just been digging a bit deeper evidently nand ram writes 1's not 0's that may be why CCleaner dont work too well. But ive found a program FreeSpaceCleaner that writes 1's I may DL that and try it CCleaner fashion, there again its going like a goodun so may wait untill ive nawsed it up a bit!
