re: [Bug-ddrescue] various issues with ddrescue and probably ntfs and cygwin

[Lance Colton]

I confirmed the permission denied and hard drive turning into a raw
device is an ntfs bug.
I started getting the error again when the image hit 300GB, so I tried
decompressing the file in windows, at which point I got a new error to
google: "The requested operation could not be completed due to a file
system limitation"
Found this article with a promising looking hotfix after some
searching: http://support.microsoft.com/kb/957065
Installed it, same problem. I then tried running Diskeeper on the
volume since they specifically advertise being able to defragment
compressed and sparse files. It refuses to touch that file, however.
I can't think of any easy or fast way to fix this now so I'm just
copying the 300GB image to a spare drive and going to put it back
again later. I wish I could bill Microsoft for support instead of the
other way around. It's sad I've spent more time copying the image
around my working drives thanks to filesystem bugs than actually
recovering the data. That drive is so near death it only works at a
certain angle now!
