LATEST REBUG FIRMWARE - Updated AUG 2ND 2013

[Xtreamst]

I have a problem recently I'm in Rebug 4.46.1 REX CFW I bought new 2.5 HDD & check in PC & use EASEUS Partition Master if it is detected & working properly, it has unallocated disc drive try to reformat it to NTFS to access it & transfer some files & it transfer as normal no issue then deleted again the NTFS so it came back to unallocated disc drive. Then I put my new 2.5 HDD to PS3 & plug my USB stick w/ Rebug 4.46.1 REX CFW near PS3 BR Drive then everything's goes normal as formatting & installing the firmware but after PS3 reboot & asking press PS button its load as normal but after that it say The data is corrupted (8002F325). I checked again the MD5 of Rebug firmware to see if the code are match & it says yes it's match so I do it all over again but always failing after rebooting so what is the problem did I do it incorrect? please help.
