Bumping this thread because I'm having the same problem with three internal Sega discs that I am trying to dump for Redump.
ice.exe is bugged and won't work for some discs.

I'm going to reference these discs at Dumpcast (I am the owner of the Dumpcast site btw).
System Disc 2
GD Drive Repair Program
DC Checker for Repair

The problem here is that ice.exe is expecting a 4-digit hex value in the IP.BIN header at 0x30 in the descrambled dump. This hex value is a checksum of other fields within the header. On this Virtua Fighter 3tb disc and others, including mine (and other discs I don't possess undumped by Redump like this DC Checker for MP), at 0x30 is the text "SEGA" or "SEGAS" -- which is not a hex value. Instead of failing gracefully, ice.exe crashes before descrambling the dump.

I downloaded DiscImageCreator to use that instead but the unfortunately the functionality to descramble discs dumped by dcdumper has been taken out at some point. The old builds that do have this functionality are not on the DIC github.

Fortunately there was a mediafire link to an old version left over in that thread. I am attaching that file to this post.

In order to use, do:
DiscImageCreator.exe -dec dense.bin <LBA>
which will spit out a "dense.dec" file.
for example:

c:\Users\darc\Desktop\gdroms\VGPC GD-Rom Dumping Kit>DiscImageCreator.exe -dec dense.bin 44990
DiscImageCreator BuildDate:[Jul  7 2012 00:01:08]
Start->Sun 2019-05-05 11:36:54 Central Daylight Time
Descrambling File(size) 1185760800/1185763076
End->Sun 2019-05-05 11:37:29 Central Daylight Time

And if the HD section contains CDDA, also do:
DiscImageCreator.exe -split dense.dec
for example:

c:\Users\darc\Desktop\gdroms\VGPC GD-Rom Dumping Kit>DiscImageCreator.exe -split dense.dec
DiscImageCreator BuildDate:[Jul  7 2012 00:01:08]
Start->Sun 2019-05-05 11:39:24 Central Daylight Time
Split File(num)  6/ 6End->Sun 2019-05-05 11:39:33 Central Daylight Time

This should spit out your split separate track files.
