Files corrupting when transferring to flash drive usb stick

[NoviceWithTech]

When I transfer mp4 films from my laptop (windows 10) to my usb flash drive stick (FAT32 500gb) only 6-8 films transfer accross and the rest say that they are currupt and unable to play. I don't understand why only a small amount transfer ok and the others don't. How do I fix this problem?
The USB is for my TV which only supports FAT32. The flash drive was originally ExFAT.
Any ideas on how to solve this issue?

What size are your files? Fat32 can't have single files bigger than 4 GB
Also how many gigabytes of data are you putting on?

How big are the films?? FAT32 has a file limit of 4 GB

The files are no bigger than 2gb each and I'm trying to copy about <50 files in total

Most mp4 films (at least in 1080p) are 2 GB or less. Most likely there's a problem with the drive itself or the USB port.

Can you try a different USB port and see if that works better?

If it doesn't, can you try transferring something else big and see if that copies correctly? (To make sure, do a SHA checksum on your computer's drive and the external drive and make sure they are the same thing.)

There might be something wrong with your memory stick, try checking for errors

I've tried the other ports with the same results. The first 6 or so transfer not a problem but the others won't which is what I can't understand

That sounds like a bad chip/sector on the disk. Can you clear it, then try just one or two of the problem ones? That way we can isolate it's a sector problem.

Alternatively, you could just do a disk check where you test and mark bad sectors on the external and see what it finds. It's will take some time to do that, so I'd set it and leave it.

How do I clear it. I'm a novice at this kinda stuff

I should mention I have 3 flash drives and they are all doing the same

Oh, I meant clear the drive (quick format). Then we can see if the first part of the drive is good with any file (expected) but once we get farther along in the spindle, it starts having problems.

Is the external a new drive, a repurposed drive, or something else? I tried 10 and didn't like it so I went back to 7, so I can't give a step-by-step.

What I'm suggesting is:
wipe (delete everything on) that external drive (back up anything on it that you don't have elsewhere!)
Copy a few of the files you are having problems with
See if those work while they are the only things on the drive
IF THEY DO
-- Most likely some of the flash chips aren't working quite right. This may happen on older or poor quality stuff, but rarely on expensive stuff. You'll have to find the way to check flash drives in Windows 10, it was "right click on the drive in Windows Explorer -> Properties -> Tools (tab) -> Check Now.. (button) " in Windows 7, it's something similar in 10 I hope. Then say something to the effect of "Scan for and attempt recovery of bad sectors". It isn't exactly traditional sectors on flash, but close enough.
IF THEY DON'T
-- Most likely something on the files themselves aren't compatible with whatever you are trying to play them on. This could be codecs issue, but it could be others too.

I hope this gives you a starting point!

Whoa, three? That sounds like a media issue instead of a medium issue. The files themselves must be not compatible. What are you trying to play them on?

I've had better transfers (no errors) with TeraCopy. Turn on "Always Test After Copy" does a CRC check.

I've loaded up two of the files which were problematic and they are running fine. I've error checked the drive and no errors found. Any ideas?

I have the same problem. I converted all my Yellowstone mkv files to mp4 for my Phillips TV to accept. They played okay on my desktop but when I formatted my MADE IN USA usb drive to fat 32 and transferred them to it. they won't play. So I reformatted and only transferred 4 out of 9. Two of them played. So I go to my laptop and transfer all 9 files to it using direct transfer,,,,they all play. Reformatted a different usb made in usa to fat 32 and about half or more would play. Rest would not. Re converted them to avi files. Worked fine on both computers,,wouldn't work on 4 different usb sticks fat 32. Finally after re copying them back and forth between two computers and 4 usbs I got all 9 series on one stick to play on DT/Laptop. Then while playing the series on my TV, one that played before "Blood the Boy" on usb in DT/laptop now wouldn't play in TV. Tried 3 different TVs.,,,same results. no files over 2.5 gig.
I've been working with computers since the early days of dos in the early 80's and the problem has thus far eluded me. I'm never to proud to learn if anyone has the answer. BTW desktop computer win 10, laptop win 7. Formatted on both machines fat 32 and went thru all the steps on both. Some videos say file corrupt can't play. VLC, WMP, etc
