Re. PR kern/48316. I recently got myself a 300 GB USB disk (which is
mine, wohoo!). And I figured I'd look into this again.
Now, I formatted the whole disk with one big NTFS partition in Windows
2000 (all recent service packs included). The result of "chkdsk c:" is
attached.
But if I now try to write anything on this filesystem, I only get error
messages. I have attached a transcript where I show some data about the
disk/partition, and what happens if I try to mount and copy a file to
the partition. Why can I not copy anything to this NTFS partition? Is
NTFS writing a no-go?
PS: I only tried the new disk + NTFS partition in FreeBSD 5.2.1 (using
FreeSBIE actually) this time, let me know if you want me to try another
version of FreeBSD or anything that can be of help.
Cheers,
--
Anders.
