The wide-band Suzaku spectra of the black hole binary GX 339-4, acquired in2007 February during the Very High state, were reanalyzed. Effects of eventpileup (significant within ~ 3' of the image center) and telemetry saturationof the XIS data were carefully considered. The source was detected up to ~ 300$keV, with an unabsorbed 0.5--200 keV luminosity of ~3.8 10^{38} erg/s at 8 kpc.The spectrum can be approximated by a power-law of photon index 2.7, with amild soft excess and a hard X-ray hump. When using the XIS data outside 2' ofthe image center, the Fe-K line appeared extremely broad, suggesting a highblack hole spin as already reported by Miller et al. (2008) based on the Suzakudata and other CCD data. When the XIS data accumulation is further limited to>3' to avoid event pileup, the Fe-K profile becomes narrower, and there appearsa marginally better solution that suggests the inner disk radius to be 5-14times the gravitational radius (1-sigma), though a maximally spinning blackhole is still allowed by the data at the 90% confidence level. Consistently,the optically-thick accretion disk is inferred to be truncated at a radius 5-32times the gravitational radius. Thus, the Suzaku data allow an alternativeexplanation without invoking a rapidly spinning black hole. This inference isfurther supported by the disk radius measured previously in the High/Softstate.

Is the black hole in GX 339-4 really spinning rapidly?
