Does Windows 10 support disk on key 1TR?

it is impossible for you to format flash drive which is larger than 32GB from NTFS to FAT32 by this way

What is a TR? The common term for TeraBytes is TB. And it is true that Windows cannot format FAT32 partitions larger than 32GB but for the purpose I boot to a GPARTED LiveCD and can create and format much larger FAT32 partitions, last 2 I've done were 120GB and 256GB on portable HDDs. When Windows uses a 64GB USB Thumb drive for the recovery it will format as 32GB FAT32 and the remainder of the drive becomes inaccessible, I had to use GPARTED to wipe the partition and set it back to a single FAT32 partition as it was when shipped.

MIKE S, thanks for reminding me, I did miss H2testw
Anyway, I checked on one of the flash drives with H2testw (recommended) and it said that "The media is likely to be defective" , in addition there was this warning "Warning: Only 7834 of 999967 MByte tested." So, I guess this case is closed and I wil return the items to it's vendor.
The flash drive is not of a known brand.

I would like to thank each and everyone of you guys for your time and good will to assist and help. I learned a lot out of this case.

Take care,

Sorry to hear this but, unfortunately, it's what I suspected from first reading of your thread.
The vendor sold you an 8GB drive that was reprogrammed to look like a 1TB drive.
Good luck with the return process!

mike s, you are right of course. Thank you so much.
