Page 2 - Problem copying files to USB memory stick

[work around suggestions]

another option is creating a shortcut in the right click "send to" menu and see if it makes any difference on the larger files...

if you have a file that constantly corrupts you might try zipping it up and see if it makes any difference

Is it the same files that you are constantly trying to copy or are you just choosing any large files to test this at the moment ?

Did you try another USB stick for the testing purposes?

Also when you safely remove the USB stick, is it successful? or do you get some errors?

I have had the problem with more than 1 stick

When I 'safely remove' it is usually without errors, but I've noticed sometimes when removing a 'real' external hard disk [one that spins..] that it may take 3-4 attempts to safely remove it, getting a 'device cannot be removed at this time' error

tried sendto on a folder with a 900MB AVI & a 16kB JPG; the JPG copied OK but the AVI won't play

the first time I noticed the problem was with a 100MB part of a RAR'd archive. Its not 1 file I keep having trouble with, its mostly bigger ones tho. I can't imagine zipping would help.

It is not the same file all the time. I have noticed it particularly with big files; when I am trying to replicate the problem I usuually pick a big file

Try plugging you USB drive. Right click on the drive and click properties, goto Hardware tab and click properties.

On the properties, goto Policies tab and choose Optimize for performance and click ok.

Can you give it a shot and then test 700MB+ files?

It is already set for Optimize for performance

Can you try copying in safe mode?

Is it always a case of the large file not being there when you move the thumb drive to a second system? or are you trying to actually run/play the file from the USB drive?

Also....I say again, have you tried archiving large files and then loading them?

This seems to be motherboard driven problem and not specific to the OS or the Drives themselves. I have formatted and used different OS Ubuntu and XP etc.. Same devices and same problem is persistent. I have used different USB drives and the problem persists. Anything under 2 GB drives do NOT have the same problem on the same hardware. I do not have 4 GB to test if that would make a difference, I have used 1 GB 2GB and 16GB but the 16GB are corrupting the files after copy. Some files work, some don't. Usually the larger files are not retaining their data upon copy. This may be a copy.dll issue or something like that but it's not the USB drives. I have seen many of the same issues being reported by multiple threads on different sites. I use the USB to transfer footage to my Blu Ray player to watch for editing purposes and to watch d/l video that I don't need to burn to disk. But the files will function from source and play with no codec problems etc... Then after copy to large USB platform they become corrupt. It's absolutely not the drives as some people have suggested. This seems like the USB interface motherboard or CMOS and BIOS related issues. Perhaps Virus related or Antivirus program related.
