Dummy sectors, I guess.

Please also check by IsoBuster. /c writes the protected sector number to file. /f deletes the drive cache when reads the disc.

Or developer may hide some file intendedly.

So... this is possibly the weirdest issue I've run into so far. With the last few builds, there is a single CD game of mine that will get to about 56000 sectors and then the drive pauses and then reboots. When the drive comes back, it doesn't recognize there's a CD inside anymore.

The reason that I'm even posting this here is that I have NOT had this issue (same drive, for clarity) with either IsoBuster or ImgBurn. I can attach the logs, if those would be helpful, but I was wondering if anybody else ran into this before and if there is any ways to get around this.

Nexy screamed about the similar case from /viewtopic.php?p=23509#p23509 to /viewtopic.php?p=23525#p23525

Ah interesting. Never ran into this before, so thank you for the second link. I will try the power cycle multiple times and see if that works. I had only let it reset once between attempts.

Another problem (sorry I didn't check entire topic, I may repeated problem already mentioned).

When I use command like:
cd D:
D:\DICnew\DIC.exe cd w GAME 32 /c2 /sf

program crash when "Creating bin, cue and ccd..."



EDIT. Ignore it, works like this nicely:

cd D:
DIC.exe cd w Game\GameDisc 32 /c2 /sf

DIC should work on Sega Lindbergh games? They're DVD...

I found one on eBay for cheap http://www.ebay.com/itm/SEGA-Arcade-LIN … Sw3YNXYtxa

Thinking about buying.

If there isn't any protection, it'll work. Please try and report.

Have you done anything with regard to the above copy protection. I have several Original releases from that publisher, which always seem to use the same protection scheme.
