Re: OT: corrupted .NEF files


EOF errors generally occur when a file is "incorrectly" created.  This can
mean many things, but the basic idea here is that these errors result when
a file is missing information.  It sounds to me like the PC Inspector
software probably couldn't fully salvage those remaining raw files, for
whatever reason.

I think it's fairly unlikely that third party software will be able to
open the troubled .NEF files, although not impossible (it's worth a try,
at least).  I recommend going back to the hard drive and trying out a few
different applications designed to recover data.

I don't know the extent of your computer experience, but if you (or
someone you know) has any experience with Unix/Linux there are some great
(free) utilities out there for data recovery.  I did a bit of searching
for some open source Windows software that may help you, but didn't find
anything worth mentioning.  Unfortunately, it may boil down to how much
money those images are worth to you.

I'll keep looking; if I find anything, I'll let you know.
