I format my Sony Vaio usb2.0 flash drive of 1.9TB .at first when I slot the usb it ask me to format it and when I did with a : system files FAT32. I finally format the flash drive and store my videos or any files in the flash drive the Videos does not play and the same thing happens when ever I open my files in the flash drive it does not open with the same Words that I personally wrote. Can any body please help me?
I'm afraid you've bought a fake flash drive. I know, because I've just done the exact same thing! ¯\_(ツ)_/¯
It turns out I bought a dodgy 2TB flash drive from eBay with a tampered capacity - what was supposed to be an amazingly large drive was in fact only 8gb, though it showed the faked size in Windows and on a sector scan. I've learned there's currently no such thing as a real 2TB flash drive. Not even close.
What tipped me off was when I copied across about 20gb worth of .mkv files. I found that some of them were working fine, and then everything after a certain point was broken. They were broken even though the file sizes appeared correct, and there were no error messages during the copy.
I tried all sorts of things to fix them - scans, chkdsk etc., but came up with nothing. Sometimes after disconnecting and/or restarting it would accept an extra 1gb video, and it would play while it was still plugged in, but then when I ejected it and plugged it back in that file would be corrupted, as if all of the metadata was gone.
I finally figured out that it was the first 8gb that worked, and everything beyond that was faked. I feel like a total idiot for wasting so many hours, when in the end the answer was obvious - it seemed way too good to be true when I bought it, and it was.
It's one possible reason some of your files will work, but others won't, when there appears to be no rhyme or reason as to why. Hopefully this will save you (or someone else) from wasting time trying to figure out why the universe seems so random and cruel. ;)
Hey there abubatoure.
I guess you mean GB instead of TB. Try the flash drive with another computer or device to see if the same thing happens. Try reformatting it with another computer. Some manufacturers also offer formatting tools for their USB flash drives and memory cards so you can try that as well.
You could also try if the flash drive acts the same in different USB ports - 2.0 and 3.0
Unfortunately there's always the chance that the flash drive might be failing if nothing works for you. :(
Please let me know how everything goes.
