Sure?

Also, is it a bad dump?

Yes, that (1) there is a definite problem. Also, track 03.bin does not match the verified TOSEC dump. IMHO a definite bad dump.

@MajorPBX: I am fairly sure the offender is the 1st section, which took a while to match. I have seen this on some of my dumps too, dcdumper getting a match after struggling with a segment, only for ice.exe to spit out an error afterwards.
If you have kept the partial dumps, delete section 1 044990-055278 and let dcdumper try again. This will save the hassle of reading the entire disc again. Worked for me several times.

if that doesn't work, then just use the tosec method for the hd area. if there's one track in the hd area hashes will be the same as redump method (when redump method works)

I believe it will work on a repeat dump, I had this scenario with ice.exe throwing an error after dcdumper had difficulties dumping a specific segment several times while dumping my stuff. Trying again later generally resolved the problem.
Majorpbx already said the disc is in good condition, so my expectation is that it will be fine after a redump.

Redumped and Track 3 now matches TOSEC results. Section 1 was the culprit.
