don't have external drive that big
Merely copy your Windows files to a NTFS drive volume. Not sure of your internet speed, but uploading 400GB would likely be very slow.
drive options though you don't give your physical location or any other useful info:
$60 at Amazon.com WD 2TB Elements Portable External Hard Drive HDD, USB 3.0, Compatible with PC, Mac, PS4 & Xbox - WDBU6Y0020BBK-WESN
$110 at Amazon.com SAMSUNG 870 EVO 1TB 2.5 Inch SATA III Internal SSD (MZ-77E1T0B/AM) with a USB adapter if needed.

If you're looking for a Swedish counterpart for Amazon it's Cdon.se I personally dont buy there that often. It's cheaper elsewhere most of the time. To find which websites are cheaper we just prisjakt.se / Pricerunner.se
But here's an example. The WD 2TB portable external harddrive on amazon . com seem fairly eh the name is extremely long but on the Swedish amazon they've now got serial numbers that no one wants or needs to know.
They've somehow decided to push ever option onto that same page even when the "Styles" are named the same thing while not being the same thing which is extra confusing and one untranslated option...
But on Cdon it's cleaner the name isnt long af or include unnecessary stuff that isnt a part of its actual name. Does also add that other sellers on Cdon sells it for cheaper and you also got a "Price History" tab below so you can see well its price history how nice of them.
If you're buying electronics in some shape or from you got komplett.se inet.se netonnet.se dustinhome.se
Want specifically audio stuff? Hifiklubben.se
Looking for gym stuff? Gymgrossisten.se Mmsports.se
The list goes on and on, there's a lot to choose between really, some of varying level of quality but it depends on what they are selling really. But I picked the ones that I would say look better. Inet looks the most bare bone Ig, but it's mostly for geeks and what not so.
Curious if it was this one? https://www.amazon.com/Western-Digital-Elements-Portable-External/dp/B06W55K9N6/ref=sr_1_3?crid=1OD87GLBOL1PI&dchild=1&keywords=western+digital+external+hard+drive+2TB&qid=1592269245&sprefix=Wester%2Caps%2C141&sr=8-3 Tempted to jump on it given the markdown.
I purchased the 2tb Western Digital USB drive last night and plugged it in. No more disconnects! It's working great now. Looks like it was a user error by not reading the manual - completely. Thanks again for the support.
