Good day to all nerds.

Again, rather I should call it New USB Flash Device Problem 2,
(but I may end up hijacking my post just from that title.)
But my first problem there...
(which i have said earlier in my problem that
it doesn't have a name or driver in itself.)
That first problem, is maybe, connected to my present situation.
Moderators may modify my post if something's wrong. Danke.

Currently, I was copying my files to my flash drive Transcend JetFlash V30,
but after in a matter of intervals an error message pops out, stating like this:


An unexpected error is keeping you from copying this file. If you continue to
receive this error, you can use the error code to search for help in this problem.

Error 0x80070570: The file or directory is corrupt and unreadable.


Trying and trying again for an eternity doesn't work.
Any answers?

Quick diagnostic workflow and practical fixes for Error 0x80070570 when copying to a USB flash drive (Transcend JetFlash V30). The replies above point at file corruption and Windows copy behavior; below is a step-by-step way to isolate whether the problem is the stick, the PC, or the transfer method, plus safe recovery/workaround commands.

Try these in order to isolate the fault and recover data:

  • Test the stick on another computer and in a rear motherboard USB port (avoid hubs/front-panel ports). Also try a different thumb drive on your PC to see if the error repeats.
  • Copy only a small file to the drive. If that works, try progressively larger files to spot size-related failures.
  • Back up anything still readable on the flash before running repairs.
  • Run an error check from an elevated command prompt:
    chkdsk E: /f /r

    Replace E: with the drive letter. /f fixes errors, /r locates bad sectors. Run as administrator.

If Windows seems to choke on large transfers, use an unbuffered copy to avoid buffer-full issues:

robocopy "C:\Path\Source" "E:\Path\Target" /E /J

The /J switch uses unbuffered I/O and often gets around Windows copy stops when writing big files or many files.

Other useful checks and cautions:

  • In Device Manager, uninstall USB Mass Storage controllers, then replug the drive. Try disabling any real-time antivirus temporarily while copying.
  • Check Disk Management for correct reported capacity (fake-capacity drives will misreport). Tools like h2testw (Windows) or f3 (Linux) can confirm real capacity.
  • If chkdsk finds many bad sectors or the drive fails on multiple PCs, the USB stick is likely failing or counterfeit — stop using it for important data and replace or RMA it if under warranty.
    This approach builds on ’s source-check idea and complements ’s observation about Windows copy behavior, while giving concrete commands and tests to determine the real cause.

well, it appears there's something wrong with the file you're trying to copy.
just trying again won't solve the issue I'm afraid, you may have to go back to the original source (hope for you that isn't the not back-upped original of your file) and download it again, or copy it over your current file.

Windows does this when copying large amounts of data to USB flash devices and thumb drives. I have experienced this frequently on my Windows 7 work system. I think that it is not responding properly to buffer-full conditions on the flash device. I remove the drive, and plug it in, restarting the copy from where it stopped. I had to do this numerous times recently when copying about 20GB of training videos to a USB flash drive for my company. Never had this issue with XP, but then I haven't used it for such purposes for a long time. My main OS is Linux and it doesn't have this problem! :-)

No no, sir. Every file I copy shows the same message,
and it only occurs when I put files in directories, or rather commonly called, folders.

So I doubt the FAT32 is corrupted, so I formatted the disk. To no avail.

You're lucky dude. You just own a Linux ;)
