Suitable software for checking PS1 CD integrity?

I've tested dvdisaster for this with a few (original) games, and no matter if the CD is scratched to hell or looks mint, it always throws out the same pattern: first sector red, then about 33% of the CD reads out green and the rest red again, with a "illegal mode for this sector" message, suggesting that the tool has an issue with how these CDs are laid out. Of course nothing can be deduced from these results. I did try the "read sectors raw" option, no difference.

Also gave CDCheck a quick test, that one seems to read every disc without errors but gives a smaller number of read data than what is actually on the disc... again, doesn't seem to be very reliable.

 

hi Xan , if i'm correct you can read the PS1 disc to an image then compare it with the MD5 etc on Redump.org. There's a ripping guide on the site on what software to use to dump the disc.

thanks for the confirm and backing me up Mord........appreciated

 

hehehe great response Mord , made me laugh this morning

 

Using dvdisaster on PlayStation CDs isn't going to work for a couple of reasons - the first is that a lot of PS CDs have broken EDC/ECC in the first 12 sectors because of a bug in Sony's mastering software. The second is that they use a mixed-mode CD-ROM XA format, and dvdisaster only supports mode-2 form-1 for XA. The result of this is that any sectors that are in form-2 (basically, XA audio or STR files) will be flagged as bad.

 

I've been aware of redump.org, never gave it too much thought though due to how their dumping tool needs one of those old Plextor drives. Might be a good time now to pick one up now for future archiving...
