Title: how to recover backup from split iso data track?
Post by: wawrzon on July 01, 2009, 04:40:19 PM

i just lost my system partition almost completely. damn sfs! (never again):/
the title says pretty much what i want to know. i have made an iso image with frying pan (unregistered, so i cant burn it atm) some time ago so maybe i could use this backup. is there some possibility?

btw i have here an install cd of pfs2, is it any good, safe to use? i have a second total sfs crash within half a year and am getting tired of it.

I never had a complete loss with PFS2 / PFS3 but there are still some bugs in PFS2 compared to PFS3 which was always completely stable for me.

What is a "split ISO data track" ? Can you make a non-split ISO image from it, i.e. can you join the parts ? If you have a complete ISO image (one file) you can use whichever software you like to burn it. For example MakeCD is freely available now. http://www.estamos.de/makecd/

yes if it was an iso image it wouldnt be that much a problem. im just not sure how to join the parts.

there is a .sii file acompanying the parts with the following content:



   
   


you think i could just use a join utility and then rename the file to iso?

Messages like "index block nnn has an invalid id" with the partition remaining write protected. Most such errors could be fixed by running the DiskValid utility or RemoveDirEntry followed by DiskValid. Sometimes I had to backup / format / restore. But as I said I never lost a complete partition. Files were always readable at least.
