copy large file to USB drive hangs

When I copy large files to my USB drive, it hangs. I've done some
checking and found there is a problem with Win2k that is fixed in
SP2. But I'm already using SP4. Any idea what could be wrong ?

I don't think it's a hardware issue. I've use the drive on a XP
machine and I can copy large files.

Thanks for your advice.

Petrform a complete CHDSK on the drive.
 
I've done chkdsk /f /v /r /x. No errors. I have the same problem
with another external USB HDD. I don't think it's a problem with the
hardware. Something is wrong with my Windows 2k.... any advice ?
Thanks.

Try doing it from a Command Prompt and report
what happens:

copy "d:\My Files\Some File.doc" F:\{Enter}

Perhaps then there is a problem with either the USB drivers or the chip-set itself.

Is there a common file size that causes the problem? What is the format
of the USB drive (FAT32, NTFS?) USB1 or USB2? How are you copying
(Explorer, command prompt, other program?)

How big a file? How is the USB drive formatted?

There is a file size limitation of somewhere around 2G (I think) for FAT32.
 
After some time, the USB HDD light will go RED in colour and my
computer will hang. I have to unplug the HDD. There will be an error
thrown about not able to save all the data....etc
 
How do I trouble shoot this ? How do I get the USB driver ? Is
there a website for me to download ?
 
1. It's NTFS
2. USB 2.0
3. I've tried all methods: dos prompt, explorer, Total commander.
Allway Sync, xxcopy, ycopy.... hang
4. I've also tried to use NERO Backup. But NERO breaks the file up
after certain size.
5. My files are > 1GB in size. Also happen for < 1GB.
6. I did some research and found some info on the Windows function,
CopyFileEX and CopyFile. I thought these utilities are all using this
function. So I thought I can try using a Unix port of CP command to
copy. Hey it's worked... but it does not eliminate the problem. I
did once encounter a hang (HDD red light) but I manage to copy many
files over. I'm just thinking that the Unix CP is using read to
buffer and write from buffer... but it still hangs, so I don't have a
conclusion at the moment.

Does this machine have USB2 hardware?

I had this trouble on an older machine with
USB1.1.

Examine the USB setup in Device Manager.

It would be based upon the chip-set. For example, if it is an Intel chip-set then you can
get the software from Intel.

What brand/model external drive or enclosure (if you put a normal drive
in a case)? What does a RED light mean?

Should have also added: Is the drive powered by the USB port, or does it
have it's own power supply?
 
I have 3 external USB HDD. 2 made in China (no name). 1 made in
Korea (Sarotech). All experience the same problem.

No activity. Continous green light.
Activity, red/green light.

Seldome get continuous red light in normal operation. But that's what
I'm getting now when the PC hangs.
 
The Korean one is 3.5 inch and requires external power supply. The
other 2 China made ones are 2.5 inch and draws power from the USB but
it has a Y cable, meaning it plugs into 2 USB: one for signal +
power, the other for power only.
