Re: [Freedos-user] recovering a file? (fwd)
Why are you writing me privately for a list discussion? Not sure why these would be plain text either, they are wordperfect 6.0, actually, or why it impacts my use of Norton utilities 8.0 edition of unerace. let's focus on what I am asking, since we may get to the goal this way. plain text lol. -- Forwarded message -- Date: Sun, 10 Nov 2013 13:57:02 +0100 From: Eric Auer e.a...@jpberlin.de To: Karen Lewellen klewel...@shellworld.net Subject: Re: recovering a file? Hi Karen, so the files are on a FAT32 partition and are 12 kB and 125 kB in size, respectively. What type of file are they, plain text? How big are the files which overwrote them, respectively?

Well let me state publicly again that private communications are unwelcome unless I have granted you permission. Told you that before, then simply kept ignoring your private efforts...feel sure you will not make that mistake again. I have just posted a comparative question at the wp for dos forum at wordperfect universe. www.wpuniverse.com Where I am a member. Equally working the discussion through the survpc list where I have been a member for decades. Unless someone knows the answer to my spinwrite question, those lists may be more helpful than here.

Once you have a disk image stored in some foolproof way, you can start working on the real disk again.

Re: [Freedos-user] recovering a file? (fwd)
Hi Karen, please let me clarify: My ignored question was regarding the sizes of the damaged files and the files that overwrote them and the file format of those files. Of course having important files almost lost causes a lot of stress, but asking off-list was not meant to waste your private time. I just guessed that you considered the properties of those four files private, hence I gave it a try to ask off-list, after asking on-list first. Looking forward to hear about the progress of the recovery, of course on-list. If new questions arise, please let the list know... Regards, Eric PS: Given that the involved files are in WordPerfect format, it was a good idea to ask the WP for DOS community as well. Not sure what the link to Survpc and Spinrite is, though. PPS: Apparently Norton Utilities 8 came out ca. 1994, making it sensible that Wikipedia says it had no FAT32 support, but maybe there was an update from Norton for NU 8 owners later. -- November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.
