Quickpar question –
I got a couple of games I want to backup. But my point here is not really to make a functional ISO like with ESR. But I want to make sure the possiblity for the game on the DVD disk to get damaged is reduced. What I know is that quickpar is a pretty good utility but I'm not sure I know what is the best thing to do. Would appreciate any comments.
Should I just break up the ISO into 100 pieces with HJsplit then quickpar them? Is it even possible for quickpar to repair a clean iso with the par2 files? Hope you are familiar with quickpar here=)
just make an ISO using IMBURN ..
I think I see where your going with this, you want to make a backup of the actual .iso, instead of straight burning, purely for achiving purposes? With some par files, just in case the disk gets damaged.
If that's the case, quickpar can make a par set for a single file, so no need to split really, just make the par set, then burn the iso and par set to a disk.
Thanks adey you get what I mean.
Still need to ask. Well I guess In my case quickparing wouldn't be of an issue if it wouldn't be comman fact that DVDs deteriorate. In my case I have an unknown brand, it has a code but I don't remember it. I have had it for more than I year I think. So far I cannot say that I had any trouble with it.
So by this I need to ask when an ISO gets damaged because of deterioration. How many bytes usually gets damaged in generall?
For example if 10 % of an iso gets damaged generally within 2 years. It's good to quickpar the iso so it can make up for these 10%. What settings would be the best in terms of redundancy or block size?
Disk durability i'm pretty sure varies greatly between high and low quality media, so i think your guess is probably as good as anyone else's, but if you can get the media code, a few people around here i'm sure could give you a good indicator of how long certain brands wear over time.
My personal thought would be this, if you make an .iso, fill the rest of the dvd up with par files.
Hello so I got my disc ID code now CMC MAG-M01-00.
Would appreciate what you have to say about this then.
Would also be happy if you could tell what is the common or in my case optimal settings in quickpar to ensure the ISO can be rebuild.
I dont know what ISO you ever had that deteriorated from being stored, but i have stored all mine on the same 500GB HDD on the PC and for many years now. Ive never used anything to preserve the ISO files and they still all work just fine.
I recently been testing some game ISOs with a new USB Loader app in development and some of them are original backups straight off my discs from 2002. The discs also are still working good as new and is the best way to create a new ISO, should the one you have go bad......which is of course why i backed them up in the first place.
Its your choice of course, but its really not necessary to use a program such as Quickpar. In my opinion, its just as likely to deteriorate as well as any ISO not quickpar'ed.

Thank you for your opinion JNABK. But I have not yet had any detoriation. The whole point with this thread is to come to the conclusion what is the safest way to store if you have to use a DVD+R that I have. I'm also storing ISOs on my 500GB but soon the space will run out. Would be awesome if adey would continue his help.
Why don't you try it like this.Archive your ISO using Winrar to rar and enable the recovery record(and maybe set it to 10%).In this way if for example the ISO has false LBA or it's full of dummy files,ones you archive it,the ISO will become a lot smaller and in that way you can add more than one game to the disk and because of the recovery record even if the disk is damaged in some way you'll have better success of restoring the archive of the game.
btw I too have really old backups of my games and they are working just fine.Also why do you care so my about the backup,just put your original in some safe place and use only the backup.If the backup got damaged just burn it again using the ISO on your 500GB hdd or just create the ISO again using your original disk.
Since I have PS2(3-4 years)till now I have more than 120 games and none of them has any problems
Thanks vsub. I just get a little OCD about stuff sometime. What you can and can't do.
Still brings up some questions. How good is the recovery record?
adey told me there where some people that could give a qualified guess on my type of media, still waiting for that.
But my goal is actually putting an untouched ISO but still having some good safety incase the disc would deteriorate unexpectedly. That's why quickpar interests me more.
I'm mean for example lets say my media is known to deteriorate by 10% (10% of the iso gets damaged) after maybe 3 years then it would be good having proper settings with quickpar files that could deal with this situation when it occurs...
