Seagate External HDD won't show up.

Okay, I seem to have similar problem, yet nothing of the described here methods seem to help:

1) I am running Macbook Pro Retina (late 2015)

2) my Seagate drive is 1TB Backup Plus portable drive that I had previously used on both Windows and much older Macbook, hence it is formatted in FAT32

I am fairly certain that I have used this drive on my macbook, yet right now when I plug it in, it doesn't appear in neither Desktop / Finder / Disk Utility / System Report (USB). The cable is connected, the light is on, I can feel the drive working. Also, I connected it to my windows laptop and it is working without problem there. I don't have the Paragon NTFS drives installed at all and I am not sure if that is supposed to be an issue since, as I mentioned, the drive is FAT32.

Any suggestions are appreciated!

This process does not come up in my Activity Monitor. However, I noticed that immediately after restart the drive is showing up without ANY problems and works perfect. But if I eject it (through the command/button) and try to reconnect it at a later moment, it is no longer recognized. Any clue?

I too had this problem. My fix was to update my NTFS Paragon Driver for Mac on the Seagate website.

Follow the instructions then restart and it showed back up. I was having all the same problems where the HDD would not show up anywhere. Now it works fine.

SOLVED for me! I couldn't see Seagate external hard drive in my finder. I had to go to Finder > Preferences and ensure CDs, DVDs and iPods was checked (and make sure Hard disks was a checkmark, though this wasn't the solution). For whatever reason, my external drive fell into this category!

By far the best 'solution' that I found from this list of posts was the one that said to make sure your computer was powered on and plugged in. Obviously on older macs (and perhaps new ones) the drive takes quite a bit of USB power. Worked like a charm (not immediately, but after about 1 minute).

Whew. :-)

I had this problem and thought my drive was damaged or "dead." And then I searched for "Seagate" on my Mac and found the "Seagate Dashboard" under applications. I didn't realize that was even installed when I first used my hard drive. It recommended updating the software. I ignored the "you may lose everything" message, because it meant you will lose your previous dashboard info. Anyway, after I updated and restarted my hard drive worked and I could see it on my desktop! What a relief!

"For me, the solution was to not connect the USB connector all the way into the USB port. Just put it all the way in, and then pull it out about a millimeter or so, until you see it appear on the finder."

This worked for me!

So I have a seagste back up plus slim 1tb the light comes on solid, I feel the drive spinning no beeps. My mac book pro doesn't ever read the drive not even in disk utility I know if there is a beep or flashing light it means the drive is corrupted but I have no idea why it isn't working just stoped one day please help

Greetings lllaass,

What does my System Report mean?

I found the next solution:

1. Connect the HD to a Windows PC and run the Start_here_Win.exe.
2. Install Paragon NTFS for Mac on your iMac
3. Plug in the HD and voila it'll appear in Finder

Any other other will not work

External drives do not show an Icon on the dektop unless you have changed a setting in Finder preferences:

Finder > Preferences > General

.

Note that this setting is not in System Preferences, but a setting on the Finder Menu.

Does The drive appear in the sidebar of Disk Utility?

If it does, what kind of drive does it say it is?

PS: there is no software incompatibility reason, in general, for it NOT to show up.

One day my external drives stopped showing up under "Devices" -- all of them. They showed up in Disk Utility, thank goodness. I worked around it by going into Finder Preferences / General / Show these items on the desktop (checked the box next to "External Disks").

I tried turning computer on and off. No luck.

Figured it out -- In the Finder window, if you roll and hover with the cursor over "Devices," to the right, in grey, the word "Show" will appear. Click on "Show" and those external drives show up again. If you hover with your cursor over "Devices" again, the word "Hide" appears in grey. Click on "Hide" and the drives disappear.

I had accidentally clicked on "Hide." Duh...

I have this same problem, too. For weeks this drive kept giving me occasional error message like "Disk failed to eject properly, etc., etc." even when I didn't even touch it and was still using it! It is one of those Seagate wireless jobs with bluetooth, 500GB. Now it won't work, mount, show up, or even pretend anything on any computer it's connected to. It doesn't show up in Disk Utility, or my Finder to the left, and I've tried the Hide/Show trick. No luck.

Can anyone help? I have that little HD packed to its 500GB gills with stuff.
