Im trying to copy a TB worth of files to another hard drive, from a RAID5 array. I select all folders, copy, and paste to the drive. Except nothing happens. It wont do more than 50-70 folders of files at a time. Thats pretty ridiculous.

How big are these files? Have you tried a different program, like Total Commander, or TeraCopy? I'd even suggest RichCopy from Microsoft. –  user3463 Apr 2 '10 at 18:54

yeah stay away from using Explorer for something like this - always seems to have problems. Try RoboCopy, XCopy, or equivalents. –  mindless.panda Apr 2 '10 at 19:28
    
The problem is, my data set is 3.8GB I have to put them on 4 drives (1 connected at a time via esata). So I have to copy portions to each drive. I tried using winrar and simply save to the empty drive, with split files, but it also locks up. –  user11955 Apr 2 '10 at 19:38
    
Tried RichCopy, and its REALLY slow. –  user11955 Apr 2 '10 at 20:34
    
Sorry meant 3.8TB. The files range from 1mb to 15GB each. –  user11955 Apr 2 '10 at 20:52

Normally this should not happen. However if you are interested in getting the files copied rather than getting to the bottom of it, try using robocopy.

1) press Win-R

2) type cmd and press enter

3) in the command prompt type robocopy [src] [dst] (replace [src] and [dst] with source and destination directory paths)

Whoa, there are really Windows 7 users that still use the “Run” dialog? –  Joey Apr 2 '10 at 20:05
    
@Johannes Rossel: oh yeah. I use it all the time! nice and simple! –  studiohack Apr 2 '10 at 20:22
    
@stu: The search box in the start menu is a proper superset of the “Run” dialog, so I never felt the need of using it anymore. –  Joey Apr 2 '10 at 20:41
    
Its fairly slow. In the explorer copy/paste Im getting around 60-80 MB/s. Here Im getting 1/2 to 1/3 of that speed. –  user11955 Apr 2 '10 at 20:54
    
+1 for robocopy although I would possibly use xcopy myself for simpler jobs and include the /v and /z flags for verify and re-startable mode. –  Richard May 5 '10 at 12:51

You can use a 3rd party application until it's solved. I found Total Commander, a shareware file manager, it can do the copy works fast and flawless.

You could also try TeraCopy. I use it all the time to manage copying of lots of large files on Windows.
