|Can but echo phil22 overall re' data safeguarding.|
Wise(r) to have two sets of any important data at any time. Minimum two sets of DVD and if possible another (usb) hard drive drive - at least. Absolute minimum two sets of DVD; or one set of DVD and an external hard drive. And rather than "backup" - which means it's in code... - simply duplicate/copy data to the external storage media. Straight copies will thus be immediately available on any working system (providing it recognises the file system of course).
Equally as they're cheap enuff (for many pholks although perhaps not for all) a simple SOHo NAS is wise option too. A two drive NAS is not much cash; and set up as simple mirror system is the basic and easiest to employ. I have a QNAP TS 210 which has stood me well over the last few years. And even with an NAS - back it up to an external drive regularly... If one drive dies in a Mirror system, one simply replaces it and rebuilds the mirror from the good drive... BUT always one has an external drive backup for the server as well. I have WD Elements for mine - 1TB; and critical stuff is also on DVD.
Never having come across " .nsf " file format before... I dun a wee look-see "out there (Skully)" and discover it's usually a Lotus item?
I then dun another trawl using the string: - recover access to nsf file - and this list appears... Possibly something there may assist?
And this is list of possibles found using the string: - recover access to nsf file from R&R
There are few recovery routines in the list...; these being some of them
And this list - using the string - recover access to nsf file from R&R backup - may have a few possibles?
And a "very loooong shot..." With the drive connected via usb to a working system - and ideally another drive also connected via usb... try some of the other assorted recovery utilities; if only to get the data onto a decent disk?
Mind you that four backup on the same disk all have problems with the same file does have me more than a little curious... I'm inclined to think this not simply a damaged sector issue; rather a dodgy (at creation?) file; and if so then some of the recovery routines specific to .nsf files may be helpful (see the link above for some of those).
Save any recovered files to the second usb connected drive; and then copy them to DVD - immediately. Ideally make two sets of DVD as above... and even get another good hard drive too...
You might even mail the files to yourself; and leave them on the mailerver - perhaps on two email accounts. A simple/free form of cloud storage...
Recuva is on that gets regular recommendations here, by those who have used it.
I got into this post more as a learning curve for me; as the look-see/research may be useful at some future time. I have at least one chum who has Lotus stuff around...; and other still uses Corel - which is real pain at times if/when I have to access stuff from there (unless he manages to export it successfully into a format I can access via Word etc.).
