External HDD can be seen in Disk Utility but not in Finder I've been using my external HDD a lot of times before on my Macbook Pro 13" OS X version 10.9.5, but it doesn't seem to appear in my Finder anymore. It can be seen in Disk Utility, though. Can anyone help?

I've already checked the Finder &gt; Preferences &gt; ... And, I've already run Repair Disk and clicked on Mount, to no avail. I don't want to reformat the disk because it has years of files and pictures.

This is the info on my external HDD:

Name :  HW Drive
Type :  Partition

Disk Identifier :   disk1s1
Mount Point :   Not mounted
File System :   Windows NT Filesystem (Tuxera NTFS)
Connection Bus :    USB

Writable :  Yes
Capacity :  320.07 GB (320,071,884,800 Bytes)

Bootable :  No
Supports Journaling :   No
Journaled :     No
Disk Number :   1
Partition Number :  1
This fixed mine:

In Finder:
 Finder>Preferences>Sidebar>DEVICES>
Then I unchecked and re-checked (deselected and then reselected) "Hard Disks" and they came back. (even though they were external) Basically try unchecking and checking them all.

I'm also now running disk checks.
