Windows 7: Windows 7: Corruption in large file transfers to USB drives

Have you tried a clean reinstall to see if the behavior continues? I'd clean reinstall without any tweaking or SFV to see the difference.

As a last resort you could also try a Repair Install, but if you have corruption in the SFV program or from tweaking it might let it back through.

Tips for getting a baseline purrfect reinstall - use the ones which apply: re-install windows 7

There's some Ms Hotfixes that might come soon with the SP1:

I have already tried a complete fresh install on a separate hard drive but the same thing occurs. I have never done any tweaking on my Windows 7, I left it on default settings. As for SFV, I downloaded a fresh copy of Quicksfv each time so I doubt it was corrupted itself. I have been using Quicksfv for over a decade now and it has never let me down.

I have looked at these hotfixes, but none of them apply to my situation. My motherboard has an Intel P35/ICH9R Chipset not Nvidia. I have Windows backup turned off so the other two patches won't do much good for me either.

I have tried copying with Robocopy, but I still get the same random corruption.

I have moved to Windows 7 Ultimate x64 for almost half a year, recently my hard drive was getting full and I decided to move some of the data to usb external hard drives. Both the externals I have are IDE hard drives and both are NTFS. I always use Quicksfv to make a CRC check file before I transfer the file and then run the CRC check after its been copied over to the external drive. I have used these externals in the past with Windows XP and had no problems.

However, on Windows 7 when transferring large files (usually over 1GB in size), I get corruption in the files. The corruption occurs randomly, if I recopy the files again it might be corruption free. This only occurs when copying files from internal to external, if I copy files from the external to my internal there's no corruption at all.
I have tried changing the usb cables, power cable of the externals, using different usb ports but none of it helped. I scanned both externals with chkdsk and I used memtest+ for over 24hours and all the tests passed fine.

Regards,
Pleco
Can you split those large files into smaller segments? If video files there are free splitters available. This one, for example. If no corruption occurs when large files are split it might help to narrow down the problem. If corruption still occurs it might point to a problem within the files themselves.

The corruption occurs in all file types, and I have copied many different files so they are not the same ones that are getting corrupted. It just happens to be that the larger files have a higher rate of being corrupted.

Corrupted Admin rights might have corrupted aswell your files rights. Humm, looks a repair somewhere!

But how long have you used SFV on Win7? If you've reinstalled to the same problem, then I'd try running for awhile without it. In fact I would not use any file copying program or anything like it at all until you elminate this as causing this as it is otherwise unheard of in Win7.

You should also wipe your HD of all code before trying reinstall as Infection or other corruption cannot be ruled out yet.

I actually tried testing this myself on a video I had. 9 gigs of video copied over. Reported as corrupted. I played the video start to finish. There was not so much as one tiny sound hitch or out of place pixel in the entire video. If corruption occurred it was not anything that could be detected by me or the media player.
