I have a disc that has errors on it. In fact, when I put it in my scsi plextor drive, the drive goes nuts and spits it out. Another drive it won't show a TOC. Another CD-R drive and it will finally show audio tracks on tracks 2-6 but no data on track 1. I need to back this disc up in hopes to get a working copy. Any suggestions? Alcohol 120% doesn't touch it becaus e the drive doesn't recognize it (my DVDR drive). Maybe I'll try alcochol on my system with the plextor.
I can't in case the disc gets ruined. It's one of a kind. (There's no scratches on the disc either. Is it disc rot??)
I feel you man especially when it's a GD-ROM, what ever the case might be. I, personally, would use a lint-free cloth and a small amount of alcohol to gently clean the disc. I hope it all works out for you!
1. Try another PC, CRC errors can be caused by misconfiguration of ide. If it is the disc, does it have noticable flakes if it's an old cdr? Does it have "holes" when you hold it up to the light? Is it pressed (hk) disc? If so, it may be designed to be uncopyable. First thing would be to see if the surface of the media is the problem. If you're having errors due to the dye in the cdr.. that is another matter. You have to remember with scratch doctor, the type of scratch is what matters. It can come out looking fugly, but if the laser can read the data, it'll work. You can have one small scratch that follows the curve of the disc make it unreadable.
I tried three different PCs with different CD drives. This PC has a DVD-R drive and it's not recognized. My other PC with a plextor scsi drive that spits it right out after a few seconds. That pc also has a CD-R drive and it will accept the CD, but CD-Rwin shows track 1 as nothing (not data and not audio), and tracks 2-6 as audio. On my other PC with a CD-R drive it's not recognized either. There are no visible scratches and I don't see holes in the light. It's sort of a blue dye (it's not a hk pressed cd and not a gd-rom). If I can get a CCI image burned correctly then I wouldn't have to worry so much about this disc. Also, when I put it in an audio player I can hear the music tracks fine (ie. on a playstation I can pull it up on the audio menu but it doesn't boot). It's imperative that I get the CCI file (or CCS files) burned or this CD fixed. I need to return it.
Read it with something that doesn't care about a bad sector and try to rebuild it... (use ISOBuster & CDMage)
I tried the disc in yet another PC with a HP drive. ISOBuster actually found a structure on the CD. I'm trying to extract all the tracks but it's going very slow. I'm replacing bad sectors with zeros. As long as it keeps the structure and records as an image, I think I can rebuild it with CDMage. (Hopefully) I haven't used ISOBuster before so hopefully I'm doing this right. I'll leave it working all night. If this works, I owe you one. If not, then I'm back to square one....trying to convert a CCI image to an iso. I'm crossing my fingers! UPDATE: It has been over 10 hours and ISOBuster is only 7% done. W T F?! I know there's errors on the disc, but that long just for 7%? This will take days.
There's no way CDMage can rebuild a "zeroed" sector, if it could, why would we need user data at all? You need to try to read the corrupted sectors even if they're corrupted, and hope CDmage can rebuild it, if it can't, hope that they're data and not code. ISObuster doesn't seem to be making any progress, I'd try something else before you wear out your drive, can CloneCD back it up? What you want to do is get a list of every unreadable sector and try to read those specific sectors with another few drives, you may have to splice an image together If you have a mysterious image file, KEEP IT! There's a high chance it can be easily converted to a well-known burnable image format if you can make an (even corrupted) image file of your bad disc to compare it to.
I refuse to recognize that statement. I am retrying ISOBuster and I'm willing to wait 3 days for it to finish. I don't care if the CD-Rom drive burns out. If I can get this fixed it will be worth it.
I have no clues as to why the disc has errors. I know what's on it, I even have the backup files but I need the disc image to be able to boot.
Ok, I used ISOBuster and it finally ended...24 hours later. I now have a bin/cue. The image doesn't boot most likely due to the errors on the disc. If I have the data files on my HD, how can I exchange them for the ones on the image? I tried CDMage to import but it gives me an error (probably because of different size or something). Is there a program available that will let me force a file into an image???
I'll try it! I'll try anything. I'm about to offer a reward ($5, that's all I can afford) to anyone who can successfully help me fix this disc or burn/convert a CCI or CCS image to a working bin/cue. Boy, that's swell. The MAgic ISO (Trial version) doesn't let you save over 300 mb. Freakin great.
I understand you don't want to give out details, but can you give us a little more information about what you're trying to recover? At least the platform it's on? Also, you should also register over at cdfreaks and ask them. If they don't know, I'm pretty sure nobody online will. You should ask your source where the iso originated. You might want to try renaming a copy of the big file (the .cci?) to .iso and seeing if it'll mount in daemontools.
Ok, I think I was able to do a work-around. Music tracks aren't on this image for some reason, but I think I can fix that. I think I'm getting somewhere now. I'll check cd-freaks too! Thanx! Ok, here's what I did. I made a CCI file (a large image from CD-Rom Generator). I used MagicIso to burn it as a Mode 2 XA disc. This is a PlayStation game. I tested it on ePSXe and it booted! For some reason the music tracks are all on the first track which isn't good. But I might be able to fix that. More importantly, this game won't boot on a PlayStation though. So something didn't work right in the translation, but at least I verified that it works. Now to somehow get CD-Rom Generator to work with my burners. Maybe if I can get it to burn from CD-Rom Generator it will be a working copy with music. Has anyone successfully used CD-Rom Generator with a burner? If so, which drive did you use and was it SCSI? (If SCSI, what adaptor did you use as well). I have version 1.30. Does this work on Windows XP? Is there a newer version of CD-Rom Generator that will work with more drives?
