I deleted a folder with about 30 gigs of stuff in it from my 500 gig external hard drive about a week ago. I haven't done anything else with the drive since then. The folder was too large for the recycle bin so windows just automatically deleted it. I've tried recovering the files with Recuva and Puran File Recovery, but neither of them have been able to locate the files. Does this mean I will not be able to get them back, or is there something else I can try?
