Re: dd to thumb drive, W7 permission problem

The following works on Windows XP, but fails on Windows 7, apparently because of some permission setting (even in Administrator mode).

I would be grateful for suggestions of what to change and where to find it.

Here's what I had to do to get any usb drive to be accessible on Windows 7
in fstab:

e:/ /mnt/e ntfs noacl, nouser, binary

obviously pick your own mount point(/mnt/e), source(e:/), and filesystem type (ntfs).
I put four of these lines in for e:/, f:/, g:/, h:/ to cover all (hopefully) eventualities.
May not be the only, best, approved, etc way but it got me going.


HTH,
