I want to securely wipe data from my Sandisk USB flash drives
The usual File Shredder and other shred apps which work great for HDD apparently don’t work well on USB flash drives. The repeated wipes wear out the drive’s life, and additionally due to the way the USB allocates each wipe to different parts of the drive (wear levelling), the original data could stay intact in parts of the USB memory.
I know about smashing/incinerating and encrypting data at the outset (that wasn’t done). I want the drive to be useable but have all sensitive data wiped beyond recovery.
There is Secure Erase and Sanitize but they seem to be for SSD cards and I can’t find how to do something like that.
