Help Odd Pattern of Problems transferring files

[Trupod]

I want to move videos and photos from my SG2 to my windows PC.

1.
When I try USB cable connection, the Windows Eject Device icon in the system tray correctly shows that "SAMSUNG_Android" is connected, but its Removable Disks F & G are greyed out; and Windows File Explorer sees those drives but won't open them ("Please insert a disk into...").

2.
When I connect via FTP (using Filezilla as the client on the PC, and Shuttle FTP as the server on the GS2) I can transfer only small files. Videos over 200 MB don't transfer completely or without damage. Furthermore, FTP can't delete any files on the GS2, even the small ones.

3.
When I connect via Kies Air, it cannot delete any of the photos or videos on the GS2; and it also can't transfer the large videos (same problem as FTP described above).

Can anybody clarify what this pattern might indicate?

Or suggest what else I could try to get those videos into the PC?

Thanks for your attention.

I discovered that USB debugging mode had been checked in the Applications settings. I unchecked it, and that enabled Windows File Explorer to see the GS2 and to drag and drop between it and the PC.

HOWEVER...that did not fix the problem transferring video files:

One file that is 273 MB on the phone truncates at 150 MB on the PC. Another that is 223 MB on the phone truncates at 37 MB on the PC.

This is exactly the same behavior as when using Kies Air, and same as when using Filezilla with Shuttle FTP.

Both videos play fine on the GS2. The trucated files on the PC can't.

What can I do?

I also want to transfer photos and video from my phone to my PC. Everyone I ask seems to have problems. I notoce you posted this a while ago, bur recieved no response.

Have you discovered how to get the photos and videos onto PC. I would like to save mine by burning a DVD, and also I want to edit them, and perhaps post on Youtube, or on my blog? Have you found anyone who can help with this?
