[Solved] Replacing disk failed...

I've donwloaded logs... on "disk_smart.log" I see:

=== START OF INFORMATION SECTION === Device Model: [No Information Found] Serial Number: [No Information Found] Firmware Version: [No Information Found] Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 1 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Fri Aug 19 11:35:07 2011 CEST SMART is only available in ATA Version 3 Revision 3 or greater. We will try to proceed in spite of this. SMART support is: Ambiguous - ATA IDENTIFY DEVICE words 82-83 don't show if SMART supported. A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

and on xraid_config.log, I see:

PHYSICAL_DRIVE:0:number=0,device=hdc,major=22,minor=0,raid_id=0,state=online,present=1,size=625121968,r_model=ST3320620AS,r_size=625121968,r_fw=3.AAD PHYSICAL_DRIVE:1:number=1,device=hde,major=33,minor=0,raid_id=1,state=faulty,present=1,size=625121968,r_model=ST3320620AS,r_size=625119855,r_fw=3.AAK PHYSICAL_DRIVE:2:number=2,device=hdg,major=34,minor=0,raid_id=2,state=online,present=1,size=625121968,r_model=ST3320620AS,r_size=625121968,r_fw=3.AAD PHYSICAL_DRIVE:3:number=3,device=hdi,major=56,minor=0,raid_id=3,state=online,present=1,size=625121968,r_model=ST3320620AS,r_size=625121968,r_fw=3.AAD

What is "r_size"? Why on new drive is 2113 (625121968-625119855) small then other disks?
In other disks, "size"="r_size" but on new Seagate "r_size"<"size"
Could be the problem?
