Problem with SD Card Shield V4 with Arduino Uno R3

I have installed your SD Shield V4 on Arduino Uno R3.
I have installed arduino IDE 1.6.5-r5
I have loaded CARDINFO SKETCH (example in IDE) with
const int chipSelect = 4
but SD card initialization failed.
I have tryed your SKETCH on WIKI page (note) but it was the same thing (SD card initialization failed).
I have tryed four different SD formatted in Fat 16 or Fat 32 :
SD 1 Gb; SD 2 Gb ; MicroSD 2 Gb; MicroSD 4 Gb; but SD card initialization failed too.
I think that the problem is the SD library SD.h and SPI.h on IDE 1.6.5-r5.
Have an idea? Thank you!

Sorry for the delayed reply.There is no problem with the library.

We have tested it and it worked perfectly.

The arduino IDE 1.6.5 r5 previously had some bugs which has been cleared recently.

Please try using previous version of IDE or the same IDE which has cleared the bugs.

Thanks and regards
