34	COPY (or XCOPY) /V results in SYS0031 (Device not functioning) or end of process	Lewis Rosenthal		"The following is observed with r175 (n: is the FAT32-formatted USB stick - primary partition):

{{{
[C:\]copy n:\* c:\SANDISK16GB /v
n:\file1.dat
SYS0031: A device attached to the system is not functioning.
}}}

Going the other direction, no error is observed, but process stops after first file.

The same actions work as expected under HPFS (tested against another USB stick with a similar single partition, same USB stack & settings).

CONFIG.SYS has:

{{{IFS=C:\OS2\BOOT\FAT32.IFS /h /ac:h}}}
