I have a 1TB Seagate (FAT32) and 4TB Seagate (Mac OS Extended), and the 1TB works perfectly fine under USB while my 4TB just shows up in disk utility. I have 2 external drives that do not mount. And my apple usb wired keyboard doesnt work either. My WD external hard drive will not mount and does not show up anywhere. I restarted my MacBook Pro (OS 10.11.6) in Safe Bit mode, but it did not mount that way either. It did not shop in Disk Repair, and WD Utilities crashed in Safe mode. AldyWaani April 23, 2017, 2:45pm. Quit Disk Utility and, if necessary, the installer software. Restart your mac and see if the My Book appear now. If not, you might want to try Disk Warrior from Alsoft but make sure you get the very latest version if you are running under Snow Leopard. Disk Warrior may be obtained from here.
Sep 28, 2018 Connected the external HD to my Mac but it won’t mount. I tried mounting with `diskutil mount /dev/pathToDisk` and `diskutil mount readOnly /dev/pathToDisk` but it won’t mount. The disk is formatted in the Mac OS Extended (Journaled) format (HFS+). I downloaded WD Drive Utilities software to check the HD and it passed WD checks.
From the WD board:
'Here’s a link to the WD security download for Mac: https://support.wdc.com/downloads.aspx?p=172#ctl00_WD_rpSoftwareMac_ctl03_lbtnExpand 2.4k
Install WD security and run the app. When prompted, plugin your Passport. It will then prompt you to enter your Passport password. From there, you’ll be greeted with options to update your security settings which include options to (1) remove your password, (2) set a new password, (3) add auto-unlock to your computer, and a few other items.
Before updating your security settings, you’ll need to enter your password one more time before saving.
I just did this and my drive works again on Catalina!'

A question of how – Mount, Find & Recover DATA in HDD outside of Synology Box
[With] a Synology … run into issues or Hard Drive corruption/ error in sectors etc. where I have had to pretty much remove the Drive which Synology refuses to read or work with. The question is, assuming I am able to detect the Hard Drive and assuming that hardware is still kind of functional, what way can I LOAD/ MOUNT the Drive (under Windows or Linux OS etc) on a PC/Laptop? (What tools/ software should I used to do that?)
Home NAS Recovery will work for you. Syngle-disk Synology is pretty standard setup. I have to recommend a PC, not a laptop. When the drive is suspected to have bad blocks, the common wisdom is that USB is to be avoided, and laptops are mostly limited to USB.
I’ve used several Partition Management tools and I can see 4 partitions inside the Disk as created by Synology.
That’s normal, and does not provide any significant additional information.
Wd My Cloud Customer Service
[various ext4 reading programs] none of which have been able to recover data (geeksnerds, stellar phoenix, linux reader, explore2fs, ext2explore, none of which allowed me to copy, recover or even see data files).
Wd Book Reset
That depends on how bad the disk is damaged. Also some of these programs may be not quite compatible, especially if we are talking about modern Synology with EXT4. While EXT3 is identical to EXT2 in all respects concerning read-only driver, EXT4 is different.
Wd My Book Not Mounting Mac
[also] a Linux / RAID based solution that worked for someone, but not for me.
Wd My Book Not Mounting Mac Pro
If Synology with its own, specifically adapted Linux, refused the disk, then most likely any stock Linux distro will also refuse the disk.
