I've seen similar questions on here but I'm asking anyway because it's starting to annoy me..
Here are some things to try: #1 - The absolutely best situation. External drives are powered by the USB port. The blinking light may just mean that its not getting enough power for it to work. Seagate drive is not detected by MacBook? I have a Seagate backup plus portable 2TB drive and when I plug it into my MacBook via USB the light on the drive turns on but I can't see it on my MacBook, I can even unplug it and my MacBook doesn't report back that I didn't remove it properly. For the sake of Seagate, I certainly hope not. If there is a way around their password it's useless as a form of security. Unless the volume is encrypted (which would be rare especially on a consumer level device) yeah, it can be gotten around. Most devies you just pull the drive and mount it on a POSIX OS and you're good. Re: Seagate 4 TB backup plus not being detected October 24th, 2017, 0:21 Unfortunately i have laptop, i know none who has PC, although i dismantled my laptop and directly connected hard drive to SATA port and ran Ubuntu via USB, it did not detect hard drive, ran different commands but could not find hard drive. Did it work somewhere else? In Windows / Linux? It may be that it is formatted with a filesystem which Mac doesn’t have installed. I know older OSX versions didn’t come standard with capabilities to read/write NTFS discs (i.e. Windows’ standa.

I have the newest Macbook Pro 13' Retina Display (2015). Processor: 2.7 GHz Intel Core i5, Memory: 8 GB 1867 MHz DDR3. It's running on OS X Yosemite 10.10.3 Steam 64 bit mac.
I bought a Seagate Backup Plus for Mac external hard drive and the computer was recognizing it just fine, all I had to do was plug it in and it lit up. The icon showed on the main screen, and it was automatically backing the computer up.
Spontaneously that has stopped. It is still plugged in and lit up but Finder does not recognize the hard drive. It isn't showing up on my screen. Time Machine says it isn't here.
I already attempted to try different USB ports since it is USB connected, in case those were damaged. But I don't think there is any damage to either end of the USB connection because it is lighting up when I plug it in.

Around the same time that the computer stopped recognizing the Seagate drive, it started moving slower. My internet crashes pretty frequently while other computers in the house are running fine on the modem, videos become choppy and the audio is sometimes off, and things take longer to load, or sometimes it just gets stuck loading. I don't know if this is part of the problem or not.. I did opt for the smaller hard drive which is why I am using an external.
