Clone one machines drive for use in another ???

no problem having different size drives

gpt is an option if you want it, but at just 2TB I'm not sure its worth messing with, and your bios may or may not support it. Here's a write-up of cloning from an mbr drive onto a gpt drive if you wanted to..
How to Clone MBR to GPT Disk in Windows 10/8/7

there are many cloning tools but I prefer macrium.

its possible/likely that your new drive will come with software that will do everything you need. But since you mentioned a usb to sata adapter (and your specs are not specific in your profile) it might be best if you detailed exactly what is your hardware setup, specifically:

what is your exact hardware machine right now, dell machine model and hard drive brand/model.

what is your target machine and what will be its new hard drive brand/model

and is the usb>sata adapter just for cloning, or is it a permanent part of the new machine.

Dell Optiplex 780m mini-tower, E8600 3.33ghz, 8GB RAM, 500-GB hard-drive (I haven't yet found time to identify the exact brand of the drive), Windows 7 Pro 64-bit

what is your target machine and what will be its new hard drive brand/model

Exactly identical in every aspect to the other machine.
The new drive that is coming is a WD "Blue" 5400-rpm 2-TB

and is the usb>sata adapter just for cloning, or is it a permanent part of the new machine.

This device is a handy tool that is never permanently connected to any one machine:

I got this hard-drive adapter a couple years ago and have used it to rescue pictures from numerous computers that various family members had relegated to the attic for one reason or another.

Although they always say "the hard-drive crashed", I haven't connected it to a drive yet that I wasn't able to access the folders and rescue the files.

I am assuming I will need it to connect the new drive to the source computer in order to do the cloning.

Thanks for the links and info.

you might as well use the WD-prescribed cloning method...

Thanks; ... alas, I am not having any success in that particular download; it failed the first couple tries; and, when I finally did get a downloaded zip-file, Windows would not extract it; 7-zip did extract it and there was nothing in it except a portion of a pdf manual.

I got the drive in the mail today; I would already be flying in on this cloning business, except that there is a storm front coming through and it would be about my luck to get head-and-ears into this and the power suddenly go out.

hm-m-m. I just tried it and it worked, after extracting to a folder I just clicked on the Acronis True Image exe file and it installed...

I will give it another go in the wee hours of the night; we have DISH internet service and I suspect that as being the reason for downloads not working so well some of the time.

Hi Buckskin,
Id just use macrium create the image from your good machine and install it on the new SSD.

I do NOT believe you will have a validation problem as
Machines are both Dell W7 pro
1) OEM licence - it will pre validate and activate against the current Dell bios slic table
(Internet connection is not relevant, can be on/off)
2)Retail licence - 2 different keys if so perform the install OFF-line, then change the product key

Totally agree that this is the way to go,

MISSION ACCOMPLISHED ! ! !

I really appreciate everyone's input and giving me the confidence to get this done.

As I already had it installed and the learning curve for cloning seemed to be a lot less steep, I used AOMEI BackUpper to perform the cloning operation; I figured if something went awry that I could just wipe it clean, install Macrium, and give it a go; thank goodness, AOMEI was pretty much idiot-proof and so far seems to have copied everything flawlessly.

I discovered that the 500-GB drive that got replaced was a WD-Green WD500AUDX, mfg-date 31-Jan-2014.

I did chkdsk (and repair) and defrag on the source drive just prior to the procedure.

Once I got the disc cloned and installed in the other machine, it immediately booted up (puzzlingly) in Safe Mode; maybe that is something AOMEI does for the first time boot; a restart put everything to rights and we were up and running.

I had a moments trouble getting the wireless Logitech MK270 mouse and keyboard to respond properly, but it seemed to fix itself without any interference from me; the wireless keyboard/mouse on the host machine is a Microsoft brand, hence the conflict.

I checked everything out and made sure we were good to go and then I used EaseUS Partition Master to customize the space on the new drive; I shrank the C: partition to 100-GB (it had 73-GB of contents); I made a partition A: and sized it to 900-GB to be just a shade under the 931-GB capacity of our 1TB external drives; and, I made the remaining 800-plus GB partition B:

I moved the wife's "Pictures" library from C: to A: and intend to synchronize it with one of our 1TB externals; the only files that will go in A: will be her meticulously organized photos; and odds and ends or temporary photos will go in B:, thus to not clutter up A:

I moved all the rest of the libraries to B:


So far, this operation seems to have cured the many ills that the machine was experiencing prior to this procedure.

I really don't know just what happened to corrupt things on that O/S, but it just steadily went from bad to worse; it finally got to where it would freeze up and the only thing that would regain control was a forced shut-down; in the mean time, many features had ceased to work and no matter what I did it would only have a single restore point from ages ago. Many times, I would have to resort to the repair disc to get it to boot.
It is the second of two identical machines that I bought from the same place a few weeks apart; the first one has been through combat and never flinches; and, the second one started having problems within a week of getting here.
I believe it is finally fixed now.

Thanks for reading and thanks everyone for your help.
