Review on 💾 Seagate ST4000DM000 4TB Desktop HDD (Renewed) – Reliable SATA 6Gb/s 3.5-Inch Storage Solution by Steve Harris

This is an internal drive, but I bought an external case. I formatted it on Mac and PC and even on PC it still shows 800GB. Will not read 3TB even after formatting on a PC. The seller explained that you would need a PC and a SATA to USB 3.0 hard drive enclosure, but I can't get it to work. They offered a refund, not sure if I will do it again or not. Even with great computer skills, I've never had this problem and can't figure it out. The drive is marked 3TB, I have never seen or heard of this issue. The seller said it was the hard drive, maybe I just hadn't heard of this problem, but I've never had such a hard drive and bought it. My understanding is that the hard drive just made it faster, but that's beyond my knowledge. If you only use a Mac and want a 3TB drive, don't buy it!
