DriveCleanser: Secure on SSDs?

Thread needs solution

Hello!

I need to send my computer for repair and need to wipe-out sensible data before doing so. So I backuped the data with True Image 2013 and now want to delete the data with DriveCleanser.

The problem seem to be that SSD might store the data in different cells, so the OS doesn't know that there might be a chunk of old data left in some cells unused at the moment. I want to ask if DriveCleanser is a secure tool for SSDs and takes care of that or if I should use another tool for that.

I don't know the absolute answer to your question, but I would think if you wipe and then have the partition(s) deleted afterwards you will be reasonably safe.

The algorithm doesn't check to see where data is, it just writes data to the complete disk in chunks and then deletes and rewrites data as per whichever algorithm you select. Obviously if you are sending your SSD to a government forensic laboratory none of the publicly available cleansing mechanisms preclude a government agency from finding something - that's why government agencies burn their drives after cleansing, but then of course you can't use them again! :)

For SSD's I like HDPARM. This utility restores SSD drives to a factory state and restores maximum read/write capability. Use the Secure Erase command. As Colin states, forensic data recovery is often possible.

Martho,

Use the ATA-secure erase process recommended by your disk manufacturer. Google for secure erase OCZ vertex for example.

Using a rewrite algorigthm will not work since the disk controller will do the best it can not to rewrite on the original data physically.
