I'm decent enough on the computer but have not encountered this problem before.
I currently have one SSD and two SATA hard drives on my PC. The SSD is the C: drive. Then, I have a D: and J: drive.
I don't always keep my J: drive data cable connected to the drive unless I am using it for data storage or file transfers. Today I had it disconnected. Thinking nothing of it at the time, I did a system defrag on the C: drive.
Afterwards, I wanted to use the J: drive, so, I plugged its data cable in but it does not appear anywhere! I shut the computer down and re-started it thinking it may help the computer notice that it was plugged back in, but again, nothing.
Is it possible that the disc defrag disposed of any memory of the drive, or, rearranged files so that previous locations are now located elsewhere having the J: drive reference? It's a 3 TB hard drive and I had only used about 200 GB on it. If I were to lose the information on it, all would not be doom and gloom. I'm just at a loss for idea's as to what I might be able to do to recover it.
Anyone with an idea I might try before disposing of this hard drive itself?
