DriveCleanser: Secure on SSDs?
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.

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.
