I have been trying to copy photos and video files from my laptop to a flash drive. Every flash drive I've tried seems to corrupt the same said files.

I've tried three flash drives, all of differing file systems (exFAT, Fat32, NTFS), and brand quality. The thing is, it transferred all the files successfully to my external hard drive and they are able to be opened and viewed, both from the laptop and external hard drive.

I thought maybe I needed NTFS since that's my external and laptop file system. So I tried to format both of the low-end flash drives since the high-end brand is not mine. It went for almost 19 hours, only to end in saying it cannot format the drive.

I have read many different posts and have tried many things. These same files have given me the "might be corrupt" and "cannot copy with properties" errors. But, as I said, they are able to be viewed and opened from the laptop and external hard drive.

I haven't tried TeraCopy yet, but will try that next. Still, any help or advice or questions would be appreciated.

Using Occam's razor, I would guess that the files themselves are corrupted on the disk.

To check, run the chkdsk C: command (if the disk is C:). If it finds errors, then you have the problem that fixing these errors might destroy the files if you don't have any other valid backup.

You should first use a S.M.A.R.T. tool to verify the general health of the disk.
See for example this answer of mine to get you started.

If the disk comes up as healthy, you may attempt to repair it using chkdsk. See for example :
How to Fix Hard Drive Problems with Chkdsk in Windows 7, 8, and 10.

Notes :

  • Another system check is sfc /scannow.
  • Image repair tools are found here, most are commercial but have trials.
  • VLC can be used to repair video (link).
  • For repairing video, see these articles : article1, article2 and this tool. Other commercial services can be found by googling for "recover damaged videos".

Since the files are view-able, I would open them with a program that edits pictures and then save them (one by one) to the flash drive. You might have to make a small change to a pixel in order to save a picture. It is also possible that you will get an error message when you open one of them in the editing program which can give you a clue as to what the problem is with them. Whatever it is, the copy is misinterpreting something about the files.
