HDD is "Mounted On" multiple times

I’ve got an external HDD that I can’t seem to fix on my ubuntu machine. It auto mounts when I plug it in but then mounts at about 30 different points (I can access and view the drive properly from any of them).

Mounting too many times

I’ve tried formatting/removing partitions (I believe I did that correctly in the GUI) on both a linux machine and on a windows machine, Please see attached image, any suggestions on how to get this back to it’s original state?

fdisk -l output:

Post this in question: `sudo parted -l` if only a few lines. And `sudo gdisk -l /dev/sdX` where sdX is first drive or what external drive should be. May be sdf or sdb?

`sudo parted -l` prints out what looks like hundreds of entries.

Is this drive really 14.6TiB? If so it must be gpt, not MBR although some vendors do a proprietary sector size and create all sorts of issues. But it looks like you have standard 512/4K sectors. Better to post output in question, so you can preserve formatting. IN comment it becomes difficult to read. Does fdisk or gparted give any errors like linked logical partitions? Or just show many partitions.

You have to post in question, not in comments. Then you can maintain or do formatting. You show a Microsoft reserved partition. Microsoft does that for all new drives as it is required before an install partition. But gparted or gdisk do a better job of creating gpt partitioned drives

Got the fdisk output posted in original question now. I ran a few gparted commands to format, remove/add partitions. The disk is working and accessible but still showing around 30 or so /dev mount points (if that's the correct term). No idea why.

Not familiar with Apple TV Recovery. Or is the type not correct?

Not sure why it is saying that now. I don't really know what I'm doing :(

Using gdisk, and listing all the 4 digit codes it uses I found this: `af04 AppleTV recovery `. Never seen it, but not an Apple TV user. Is this drive for use with an Apple TV? Or formatted from a Mac?

No never been used with an Apple TV or plugged into a Mac. Only windows and Ubuntu.

If you have good backups, I would just run gdisk and a write to see if that fixes anything. Or try changing type to a common Linux type. https://askubuntu.com/questions/460233/cant-restore-my-gpt-data-with-gdisk My Linux partitions: `8300 Linux filesystem ` See example on changing to 8300: http://www.rodsbooks.com/linux-fs-code/index.html

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
