have no brand and model, just "made in china". But a friend of mine have the same and have no problems with it.brand and model of this 4tb portable ssd?
test with another usb port?
It came with sorter cable, USB-C. I'm using laptop.Use a short (1ft/0.3m) high quality USB3 cable and connect the external drive to the rear panel of the computer if you're using a desktop.
Cheap badly constructed long leads (3ft/1m) connected to the front panel ports on a desktop can suffer from excessive crosstalk, causing data corruption and dropped connections.
If the drive is USB-C 10Mbps, they often come with even shorter cables, approx 8in/20cm long. Connect this short cable to the USB-C port on the rear panel of a desktop.
Make sure you've got the latest drivers loaded for your USB3 ports.
Disable Power Management for all USB3 ports in Device Manager.
I think the problem is the drive. I bought it, because it was cheap and in my head it was "It's cheap, so if it's defective, that's not a big deal, I gave these money so much times for so many *** [Moderator edit to remove profanity. Please remember that this Forum is family friendly.] , if you understand me.On the positive side you're using a short cable on a laptop so crosstalk is unlikely to be a problem. Have you disabled Power Management for the USB 3 hubs in the laptop if it's running Windows.
On the negative side, you have no idea as to the quality of your unbranded Chinese 4TB drive. Was it roughly the same price as a SanDisk or Crucial equivalent?
I'd be inclined to clear your 4TB drive and run h2testw.exe to fill the drive with 1GB files and read them back to verify the contents.
You could try swapping drives with your friend and see if there's any difference. If there is, you'll know your drive is suspect. If there's no change, then your laptop needs attention.
I tried everything and same. Decided to open it and then - it's not really an SSD, it's a cardreader with an microSD.On the positive side you're using a short cable on a laptop so crosstalk is unlikely to be a problem.

I realized that it's a fake, but still wondering how I already coppied much than 200GB data on it before this post here.because it a fake.
like these
Ооh, I see now.Although you "copied" 200GB of data to the drive, most of it has been overwritten by newer data. Most of your data written to the drive has gone.
It's the way these scams work. That's why I run h2testw.exe on all new portable media.
