COPY D:\TIFBAK\*.* L:\TIFBAK /U /S
Oops, I think you're doing this wrong - you're copying all files
in your D:\TIFBAK\ directory into one large file (TIFBAK) in
L:'s root directory (which isn't very usful)!
Perhaps . . . . XCopy will do.
#1 - Get in the habit of using XCopy & quotes:
XCopy "D:\TIFBAK\*.*" "L:\TIFBAK"
#2 - use switches to copy what is appropriate.
I use "/s /c /i /d /y" (no quotes) in my batch b/u's.
i.e:
XCopy "D:\TIFBAK\*.*" "L:\TIFBAK" /s /c /i /d /y
lookup XCopy in help and see if these and/or other switches
apply.

I have a Vipower USB mobile rack with a 300gb IDE drive enclosed that's
formatted NTFS, used to backup important files off-site. Once per month I
update the files using a batch file (4NT) using this context:
COPY D:\TIFBAK\*.* L:\TIFBAK /U /S
The problem is that it hasn't updated the files since 09/2007 even though
it would show file-copy progress and lots of disk activity as if it was
being done. Thus, I thought I was backing up the files but in fact was
not, and it seems to be unable to hold more than 118gb in that folder.
After an update, which appears to be adding files, the total used capacity
of the drive does not change, suggesting that no files are being added.
However, if I repeat a given copy command manually (e.g., COPY
D:\TIFBAK\FILENAME.ZIP L:\TIFBAK) I'm told the file exists and asks if I
want to overwrite it. It in fact doesn't exist, as it doesn't show up
using DOS DIR command, in Windows Explorer, or Windows file search.
This problem persists whether using the batch file, doing a COPY command
in DOS, or using Windows Explorer to copy the files. OTOH, if I move all
118gb existing in the \TIFBAK folder to the [u]root[/u] of that drive
(L:\) there is no such problem going beyond 118gb and all files are copied
successfully.
My D: drive, a 500gb SATA drive in the computer also has a \TIFBAK folder
which is the first-level storage device for these files, and there is no
such limitation--so I'm convinced it isn't an NTFS capacity problem. Is
there a USB interface or driver issue that prevents >118gb in a folder
under the root directory? I've solved the problem by changing the
batch-file commands to L:\ as the destination folder, but I would like to
know what's going on with this. I've been thinking I've been backing up
my files and for five months have not!
