I've been talking to somebody in my dorm who has a 250GB Samsung 840 EVO that he wants to sell to me. I asked if I could take it for the night and see if it works properly before actually buying it.

It came in a case, so I plugged it into (every) USB 3.0 port on my MSI GT70 2OC 059US - Intel Core i7 4700MQ, GeForce GTX 770M, 16GB DDR3 RAM.

After plugging into my computer, the disk did not show up in "This PC" in Windows Explorer, but did show up in Disk Management and Hard Disk Sentinel, in Disk Management, most of the options are grayed out so I can't format or assign a path/partition.

I can't find anything online and appreciate any help I can get!
Thanks in advance,

There is no drive letter assigned to it. Right click on it and Add a drive letter. make sure it is the big part in the middle you are trying to add and not the EFI partition.

Also unless you actually use it. as in install windows etc, just plugging it in does do much. yea it powers on but how well it works is a different story. I would wipe all partitions and then make one big partitions, make sure it is either plugged into a USB 3.0 port or a SATA III port on your motherboard and then use Crystal Disk Mark to test to speed and then use Crystal Disk Info to check the smart status to make sure it is a healthy drive.
