Can I use the Kanguru Duplicator's Disk Wipe function to securely erase the data off of my SSDs or flash drives?
A recent study finds that approved methods for sanitizing traditional, mechanical hard disk drives are not as effective in securely erasing the data from flash memory based storage devices like solid state drives or flash drives.
"The core of the problem is that unlike magnetic media, SSDs save data to physical pages but erase from logical block addresses (LBAs), a process which is managed through a flash translation layer (FTL). This creates a mismatch between where the ATA or SCSI drivers think the data is and where it physically resides which the drives compensate for by copying data around. It is this copying that leaves insecure traces littered around the drive." - excerpt taken from MacWorld article published Feb 22, 2011, click here to read the full story
Currently there is no guaranteed secure method for erasing data from your drive. If your SSD or flash drive contains sensitive information, the best method to ensure that your data doesn't become exposed is to apply some form of encryption.
