Bootcamp Uninistalling Error-- can Disk Utility Solve it?

Question

... my adventures with trying to uninstall bootcamp partition (32gb) continue. Made the mistake of not using the BootCamp Assistant and tried to do it manually with Disk Utility... have had problems and errors with trying to 'verfy disk' or expand HDD partition back to original size.
Funny enough my partition works as a separate drive-- see below, but my initial drive still won't be verified properly... error messages below... DOES ANYONE HAVE A SOLUTION FOR ME PLEASE? Very much appreciate it.
Disk Utility Verify process (Mac1 is original partition; Mac2 used to be bootcamp).

Thanks for the response, but your suggestion didn't work:
With the CD inserted, three CD icons appear in the left pane of Disk Utility:
1) 48.8 MB MATSHITADVD-R
2) 42.5 MB Untitled 0
3) [name of CD]
According to the information panel at the bottom, #1 is 48.8 MB, Partition Scheme: CDpartitionscheme; #2 is 42.5 MB, Partition Scheme: CDROM_Mode1; and #3 is Format: ISO 9660 File System, Number of Folders: 0, 42.5 MB, and Number of Files: 0.
When I select #1, File:New offers only Blank Disk Image or Disk Image from Folder...; Disk Image from (Select a Device)... is inactive (greyed out).
When I select #2, File:New:Disk Image from Disk1s0 (name of disc) is available.
When I select #3, same as #2.
When I try to make a disk image (DVD/CD Master) from either #2 or #3, I get the same result:
"Unable to create "[name].cdr" - Input/output error."
Could the disc be copy-protected somehow? Seems unlikely, it's a pretty simple disc, with some dictionary software on it. Or is Disk Utility unable to deal with an ISO disc? I know that the Windows/Linux equivalent to a .dmg is called .iso, but apparently Disk Utility can't make such images?
I tried the freeware utility Burn, which "Failed: There was a problem creating the image." Says it uses the same Apple engine as Disk Utility.
However, the shareware CDRevolution did manage to make an image file (its own ".cdrev" format, unreadable by Disk Utility), and did burn what appears to be a perfect copy of the CD. So my initial problem is now solved.
I'm still wondering why Disk Utility couldn't handle it.
