Very late to the party, but, if you can't seem to find the locked disk in Finder, you can use the Disk Utility program from the Applications > Utilities folder. The drive, once attached via USB, will be listed there, select it, and select "Mount". The password prompt will be triggered, enter the disk password and you should be set.
I'm using the monitor USB hub as a connector, could it be an issue?
Yes, that's probably the problem. Based on the speeds you're seeing, I suspect that the USB hub in the monitor is a USB2 device; connecting your drive through that hub is slowing down the connection to USB2 speeds.
Connect the SSD directly to your computer, or use an external USB3 hub.
There have been reports of problems when the internal drive is missing or broken, that High Sierra (10.13.4 and above) and Mojave won't install onto external drives, because it wants to update the EFI firmware partition on the internal drive.
Third-party internal replacements, which are 'blank', are also affected.
installing MacOS onto ...
You must have an EFI partition (aka firmware partition) on an internal drive for the installer to accept that. You have not provided the model of your iMac, so that might be an issue. Basically, if you have one of the older iMacs, you could replace the hard drive with an SSD. 256 GB SSD are pretty cheap, have a little room for stuff and are nice and fast.
From what I can tell the drive from an iMac G3 is an IDE type. HDDs running Mac OS System 8.6 ought to be running on the HFS+ disk format.
If you get a USB HDD enclosure with internal IDE connectors you should be able to plug the drive into it, connect the enclosure to a modern Mac and see the disk contents.
If you don't have access to a modern Macintosh ...
If your G3 has a Firewire port you can connect that directly to a more modern Mac (FW400->800 or FW400->400) and run dd in Terminal to make a full 1:1 disk image of the drive's contents. Boot into Target Disk Mode on the G3 when doing this (Boot and hold down T).
Alternatively, I believe Finder can natively view the contents of the disk. Then you can just ...
This site is littered with very detailed, yet very arcane methods of achieving this, written by people far smarter than me.
I still think the simplest & safest way is to buy Paragon Hard Disk Manager & do it from a GUI.
If disk drill won’t show you the directory structure, you’ll need to try a tool like Data Rescue it Disk Warrior so you can find the folder with one specific date to navigate and then restore those specific files. That would copy off at full speed.
use the folder named Latest unless you’re sure you want to go back to a specific point in time
However, if ...
Assuming your directory is correct, you have the following folders to move off the drive or to thin out:
558 GB photos library
67 GB Windows 7 disk image and files
If you have a good backup, you should be able to simply copy those to an external drive, train them and see that all the space you expect is freed.
The virtual windows files runs great on an ...
The /private/var/vm is the macOS virtual memory. It's a special type of file, which is mapped on your Macbook's 234 Gb (formatted capacity) SSD. In short, virtual memory is used when your RAM is full of apps and portions of it is "swapped" to the SSD.
So, your Macbook Pro has only one SSD drive.
If you have Homebrew installed, you can install ncdu with this ...
The Disk Utility application probably can not be use to fix your Mac. Below is a alternate procedure.
Start up the Mac from macOS Recovery over the Internet by restarting and immediately pressing and holding the the key combination Option-⌘-R.
From the menu bar, select to open a Terminal application window.
Enter the following command to get the GUID ...
If you wish to do this in the GUI, you can do advanced hard disk editing with Paragon Hard Disk Manager.
Not "merge" merging the containers, but most likely you'll need to remove a containter and then resize main container where the macOS resides. It can be done on the fly - i.e. you can edit the same partition/container from which you booted the system. ...
Since your drive was hybrid partitioned, I will assume Windows was setup to legacy BIOS boot. You can confirm this by enter the following command in a Terminal application window.
If Windows was set to BIOS boot, then you will get the following response.
Otherwise, you will get the response shown ...
Assuming your info is correct & there is going to be room on the 250, this should be simple in a Pro.
Put both drives in the Mac Pro.
Boot from the one that works.
Format the other [just to be certain] in Disk Utility as a single volume, GUID/HFS+ [Don't name it exactly as the other, to save confusion]

According to everymac.com, your Mac is a 2006 model which was discontinued January 8, 2008. (I made the assumption 2.66QX means 2.66 GHz Quad Core Xeon) This model originally was designed to run OS X 10.4.7. Since the
Mac OS X v10.6.2 Update is dated Nov 9, 2009, I doubt the disc you have is the correct one for this model Mac.
The OS X 10.7.5 (Lion) was ...
I would guess 10.6.2 would be just fine to boot most MacPro with that model, so you might have a hardware issue or bad DVD.
More specifically, there are 8 models with A1186 - so you might need to try OS between 10.4 but most of them would work with 10.6.8 - so I’d start with any 10.6 media you can get your hands on if you can’t get a serial number or more ...
I presume you’re running diskutil list from the Recovery environment. These disks are not real disks, shown by the ‘disk image’ phrase appended to the name of the disk. They are used to support Recovery as temporary read/write areas separate from the main HD.
Just boot back to a normal OS installation and running diskutil list will not show these disks as ...
Spinning disk drives fail, and its clicking-then-silence and invisibility to the host computers both indicate that this one has given up the ghost.
Expensive disk-repair software such as DiskWarrior might be able to repair it, or to retrieve the data. Given the clicking noise followed by silence, however, this is very unlikely. I wouldn't expect ...
Below is the procedure to fix the partition containing Mojave.
Reboot to the macOS installation disk. I assume this is a Mojava installation USB flash drive. Next, you need to preform the following steps.
Remove partition 2 from the MBR partition table.
Add partition 2 to the GPT.
Restore partition 2 to the MBR partition table. (This is an undo of step 1.)...
Time Machine is the way to go. You'll need a spare external drive for it. First you need to backup your system onto the external drive using Time Machine:
Back up your Mac with Time Machine
Once you have the backup ready, connect the new hard drive in your MacBook, boot into recovery and restore from the Time Machine backup.

I'd say you'd need to clone it.
Clones survive with all pre-registered software still intact. I've been doing this for years across several Macs precisely for this reason.
I'd recommend Carbon Copy Cloner [just because it's the one I'm used to] which is capable of cloning to any drive large enough to fit all the data on; it will be bootable & it will ...
This is just to notify everyone that after many days of waiting, I have decided enough of waiting, time for next plan. I had hope that someone would be kind enough to guide me through the steps required to fix the corrupted MBR (that that's the case) and maybe I won't have to go through the tedious steps of doing a full disk scan using tools like TestDisk or ...
Besides trying with another computer and OS, as mentioned before, a disk repair program might be able to help here. If your files are important, you should first make a copy of the disk by copying a block-by-block image of it to another disk. Then you can experiment with different repair options or, if all fails, try to extract the most important documents ...
Before doing any more scans and operations on the device, it is worth connecting the drive to a different device. Mac/Windows just see if it works. It could be that the physical drive may be damaged or shocks could've damaged or corrupted the controller/data.
The fact that it is only recently that it has suddenly changed state would indicate that there may ...
Sorry to say this but not very likely.
Especially if the HDD was used after the deletion for any period of time. The problem is that once files and directories are deleted there locations are removed from a table that maintains where they're located on the HDD. When these items are deleted, it's often the case that the data will remain on the HDD but just ...
Encrypted Core Storage and macOS 10.14.4
macOS 10.14.4 changed the behaviour of auto-mounting Core Storage/HFS+ formatted encrypted drives. These drives appear to no longer be automatically mounted.
Please let Apple know this change of behaviour in a minor macOS update is causing you problems. The more people who provide feedback, the better and the better ...
