When transferring a few videos between the SanDisk 64GB Ultra Dual Drive USB to my apple ipad Air and Google -pixel 4, the copy has been interrupted and files had been then missing from the USB.
After going through some online advice appears they are now in DROPPED. DIR, but still may be recoverable. I did download DiskDrill plus use the free trial to try to identify the video files, and it seems they are still there. Nevertheless after reading some undesirable reviews of Data Recuperation SW in general, and seeing it seems the best route may be to drop the flash drive off with a data recovery company and have them make an effort to recover (many of which also seem suspicious).
Looking for some advice on which usually approach to take that gives myself the best chance of recovering our files.
