Windows Not Detecting Samsung 0800 Drive

also i ripped my gears of war 2 twice... I check both in abgx the first one i did at default speed x12... the second at 2x although i think they both ripped at like 2x like you said.

then i checked both in abgx with write disabled. It told me that the stealth xex and ss file combination wasnt in the database but im not worried about that because i know it right since its my own rip.  But when i check the 12x iso it told me the angle deviation was larger than 3 (it was six)... but my other 2x iso was fine... what does this angle deviation do and would it be better if i went into the options and made it fix it so that my angle deviation was 0


I would let abgx360 fix everything wrong including angle deviations over 3 Just make sure to configure it as indicated in the PDF that comes with it.

Also with xbc make sure you choose your TS model from the drop down menu under options.

 I never had any problems with angle deviation yet. One time I was testing a drive that had laser issues and it ripped one of the SS sectors wrong. Lowering pot fixed that.
The abgx360 quick start guide explains

Part of the response to Challenge Types 24 and 25 (Response Types 7 and 5) is a rotational angle between 2 sectors on an original disc. The host's CCRT (which abgx360 decrypts) contains the target angles that would occur on a perfectly mastered disc when read by a perfect drive. There is also a value in the CCRT which only occurs for Challenge Types 24 and 25 that appears to specify the maximum deviation for a given angle. Currently all Xbox 360 games have the same angles (1, 91, 181, 271) and maximum deviation (+/-15). This is a copy protection system based on the fact that we cannot control the location of physical sectors on our backups, and our angles would be hugely different compared to an original. This is a fine protection as long as you can trust the drive firmware to make the actual measurement instead of simply replaying a previous response, which is what hacked firmware does. The default setting in abgx360 is to adjust the replay angles (which only hacked firmwares can see and use) that deviate more than 3 degrees back to their CCRT target values because in real world testing on a normal drive, up to 2 degrees of deviation is quite normal and deviation greater than 3 on any game is rare and could be suspicous (although it's very common to have high deviation on a dying or worn out drive). Alternatively, (paranoid scenario) a game could be intentionally mastered with a deviation far from its CCRT target and adjusting it to the target value would also be suspicious... although this would potentially cause problems for disc authentication on legitimate unmodified drives..
