I have a sony flash drive 4GB which I made bootable using Rufus s/w, but after that I formatted it to NTFS, now the problem is it has around 50 MB used space even after formatting, when I try copying any files, the transfer rate is normal but at 5 sec remaining it will take around 2 mins to complete copying.
To check this I tried it with another hp pendrive and the result is same.
Any help?
