Shockwave Assault dumping question

[Specialt1212]

I've been trying to dump Shockwave Assault for the PSX and have been getting mixed results. I dumped it the first time on each of my four drives. The Plextor & TSSTcorp came up with the same results, the Light Scribe was showing something different, and it was undumpable on the Samsung drive.

Light Scribe GSA-H55L    track01.bin size 723414048 crc 6d84d5fd md5 eac64ce84a79ac0aca32ff737b37b343 sha1 b3ad6dbcbc9daf9c457ccf465baa655e6d8662d4

TSSTcorp SH-S223L        track01.bin size 723414048 crc d1b262cd md5 52d1ebb22bad17ecd250a7eea6159f84 sha1 e285eeeab6827396b6fec653cf1490de1abfdf99
SAMSUNG DVD-ROM SD-616F  Sector Errors (wont dump correctly)

So since I got errors on one drive and different results on another I decided to redump in on all four drives again just to make sure it's be dumped correctly. I came up with similar results, the Plextor & TSSTcorp came up with the same results as they did before, the Light Scribe was showing something different and it was even different when compared to the first dump from the Light Scribe drive, and it was undumpable on the Samsung drive again.

so just for curiousity's sake I redumped it again with the Light Scribe drive and came up with a complete different result again.

Why am I getting a different result every time I try to dump the game with the Light Scribe drive?

Also since I was able to get 4 identical dumps with two different drives should I assume that the game was dumpped successfully on the TSSTcorp & PLEXTOR drives?

Before I submit the this as a newly dumped disc I'll wait for feedback here first.

i guess CD have some scraches or fingerprints on it.
you could try to clean it and set lower reading speed, before dumping with IsoBuster.

does data track have EDC for Form2 sectors?
if it does, you could run it through CDMage and likely 'Light Scribe' image will report some errors.
repairing those probably will make it match to the other images.

I cleaned the disc before dumping, I didn't see any scratches of finger prints.

I haven't tried this because I'm not sure how to change the read speed in ISOBuster

How would I be able to tell if this game has EDC?

if it does, you could run it through CDMage and likely 'Light Scribe' image will report some errors.

I ran the image through CDMage and it stated that the image had 3 corrupt sectors which it was able to fix.

But when I ran the image back through clrmamepro it came up with a new with a set of hash calculations that were completely different than the other results

I've been having problems similar problems when trying to dump Tron Bonne & Mega Man Legends Demo
