Hey guys, before you attempt to even start this process, make sure you are using a decent SD card. I would NOT reccomend getting one from auction/ chinese based websites. These include aliexpress, wishapp, ebay, ezbid, etc etc. Get your SD card from a local store or shop, or go to amazon direct. Do not use their marketplace. I bought a 256 GB Adata SD card for 29.99 off of ebay, it was SEALED, new in box, with the official adata printing and everything. Well, it was counterfeit, a 16 GB SD reprogrammed to act like a 256 GB. This resulted in 20+ hours of my time wasted, from reformatting, thinking content manager was faulty, using FTP, etc etc. I'm still convinced how ever, that most of the titles on the VPK torrent have been messed with, as I still get errors installing a few of them. (Dangoruppa, Dynasty warriors, Dungeon alliance, MGS 3 to name a few) So the main reason and really the only part you need to read.
Check your SD Card's true capacity, by using this : https://www.raymond.cc/blog/download/did/77/
That, is called H2. Its a simple SD card write and verify program. If your SD is a fraud, you will know. Select target (location of SD card), All available space, and write+verify. If you have a 256gb, no lie, this will take over 6 hours. You will know after about 4 hours how ever if there is faults, probably. It verifies at the same time it writes over. After 14.9 GB for me, the errors were steady climbing. Anywho, Good luck to you all, this process of getting vpk's moved over and installed is not hard... So don't make it hard on yourself!
