Review on Avolusion HD250U3 1TB USB 3.0 Portable Gaming PS4 Hard Drive - Plug-and-Play Storage Solution with Pre-Formatted PS4 Compatibility, 2-Year Warranty Included by Brad Bryant

Connected to the network (had some setup issues but couldn't fix anything), downloaded over 250GB of games on it in 2 days. Everything went well on the first day. I could use stuff I downloaded there. Then on the second day I turned on the PS4 and it said there was an error in the extended storage and I needed to restore it (which was one of the problems that used to happen before I downloaded everything). I tried restoring it but it said it couldn't be restored and the only way to use it was to reformat (meaning everything on it must be erased). I'm starting to pump everything now, I hope it doesn't happen again.
