Assuming we are talking Windows machines, EaseUS has reasonably priced software to migrate applications from one computer to another.

Assuming you are running Windows 10 on a machine with a UEFI Bios, you will always have at least 3 partitions and, if this is a migrated drive from another machine, having more than 3 partitions is not at all surprising. If you are cloning this drive and plan to have the clone be a boot drive, do not unclick and of the partitions.

It is easy to move your user folders in windows 10. Here are some easy-to-follow instructions on the web. https://www.dummies.com/computers/operating-systems/windows-10/how-to-change-the-location-of-user-folders-in-windows-10/
After following these instructions for the following folders: Documents, Pictures, Music, Videos, you would be wise to check your preferences in Lightroom to make sure that it is storing its catalog fileson the correct drive.

This was fun but I am not sure that my view is an improvement; I original is so good to begin with. I used Photoshop, Landscape Pro and Topaz Adjust AI to play with the image.

Assuming the larger drive is less than a quarter full, you can clone it to the SSS. Macrium Reflect does this, as does software from EaseUS, MiniTools and others. Google "clone to a smaller drive" for suggestions/instructions.

You do not need to reformat the drive to make it bootable. If you have a Windows 10 disk you can boot from it and go to install. Then select repair an existing Windows application.

But your problems will not end there. Windows is tied to your old machine including all the drivers for devices in that old machine. This means that you will have to fight your way through installing new drivers. At least you won't have to reinstall your software.

Finally, Windows will recognize that this is a new machine and will need to be activated. If you have got this far, you can go online to Microsoft. Start with https://support.microsoft.com/en-us/help/10738/windows-10-get-help-with-activation-errors.

Note that the issue with activation will probably apply even were you to reformat the drive because the Activation Server at Microsoft will recognize that the activation code has already been used.

You didn't mention the camera brand (or I didn't read the post carefully enough), but if it is a Nikon, you might consider California Precision on 28th Street in Sacramento (http://www.camrepair.com/). They have done a lot of work for me and I can recommend them. You can call or email them if you are using non-Nikon gear.

I hesitate to stick my nose in here, but what the heck.

Before trying a fix, you should try to figure out where the problem is by examining the logs: Control Panel>System and Security>View event logs (under Administrative Tools). You may have to hunt around here but I would suggest checking the Windows section, looking for a red circle with and exclamation point in it. That may point you in the right direction.

Then make sure the Registry is in good shape. There are a number of tools to do this; I use the free version of CCleaner (Google it). But before running your tool,create a Restore Point just in case (Google "Create restore point in Windows 10," if you don't remember how to do this).

Incidentally, for those whose systems slow down after an update, you might want to run the usual tools on your drives--Right click the drive and select Properties. Click Disk Cleanup. After this has run, select to Tools tab and run the two tolls listed there, top to bottom. Remember to create a restore point before doing any of this.

Good luck.

I use an Acratech Universal "L" bracket. Not inexpensive, but it includes an ArcaSwiss compatible clamp for quick attachment and removal. The design gives easy access to the ports on my D800e and D3. You will need a camera plate. As I said, not inexpensive but in this case you do get what you paid for.

I use the Acratech 1138 L Bracket. It is a little pricier than the Chinese special but includes a clamp so you can use the Arca Swiss plate on your cameras. They have 2 versions so check out their web site.

Are you willing to sell the 24-120 separately. If so, how much? And could you post a picture?

Thank you all for your advice and suggestions. I settled on a Benro Adventure 4. And I ordered the inexpensive Amazon monopod for my Granddaughter (to be shared with her father).

I have been looking for a new monopod. If I had the dollars, I would probably get a Gitzo or RRS. Has anyone had experience with Feisol or Giotto carbon fiber monopods? And, in particular, is there a good reason to avoid either brand?
