Very important file overwritten, need help.

I tried ShadowExplorer, it didn't even see the removable drive oh well.

Try this Free Memory Card Recovery Software - Freeware file recovery for Compact Flash, SD (Secure Digital), SDHD, Memory stick & most digital memory cards.

Right. Smartrecovery doesn't like me.

While trying to recover an accidentally overwritten file, I found this excellent free program that worked, even on a USB. It found the overwritten versions, plus some deleted ones.
