Dear All,
This may sound like a Windows problem, but please read on. I made a
mistake and bought a WD "My Passport" external 350GB disc drive for
use on several Windows machines, on some of which I don't have admin
access, and a couple of FreeBSD systems.
On first use on Windows the disc shows up only as a virtual CD (I
assume this is the firmware), "unlock.exe" has to be run and the
software installed (admin privileges necessary). Once it's unlocked
and the software installed, the big disc appears, the software can be
uninstalled, and the big disc reformatted as NTFS. From then on, the
virtual CD can be ignored and the big disc used on any Windows system.
Now to FreeBSD. The newly formatted (as NTFS) disc appears as two
devices - /dev/cd0 (never seen this before) and /dev/da0s1 (the normal
USB disc drive device). They can be mounted as follows:
freebsd [10:45] ~#mount_udf /dev/cd0 /mnt
freebsd [10:45] ~#mount /usb0
(/etc/fstab describes the NTFS file system type, and the virtual CD is
a UDF file system). We now have:
freebsd [10:46] ~#df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/cd0 582962 582962 0 100% /mnt
/dev/da0s1 311877845 2332729 309545116 1% /usb0
If we look at each device, the virtual CD has the WD software, as expected:
freebsd [10:45] ~#ll /mnt
total 6300

No problem. Now for the FreeBSD problem. If we look at what's on the
big disc (newly formatted as NTFS on a Windows system):
freebsd [10:45] ~#ll /usb0

Information
The only thing that shows up in Windows is the "MyStuff" directory,
which I put there. I can copy anything from "MyStuff" to anywhere
else on the FreeBSD system, no worries. But if I attempt to copy a
new file into the "MyStuff" directory, I get the following:
freebsd [10:46] ~#cp ~/tmp/test /usb0/MyStuff
cp: /usb0/MyStuff/test: No such file or directory
freebsd [11:08] ~#
What on earth is going on? Why do I get the message that "test" does
not exist, on the directory that I'm copying to? I can copy nothing
to this big disc from FreeBSD, but can copy from it OK. Why are those
other files there? Are they part of the standard Windows NTFS
formatting? Can I use newfs(8) to make an NTFS file system on the big
disc? Any pointers to a solution would be most welcome. I'm also
trying to ask similar questions on the WD lists. Thanks for any help.
Cheers,
Rob Hurle
I would use a tool like gparted and FAT32 the drive... It may run a bit
slower but both systems can read and write to it.
