Your firmware can not be updated because the hard drive...SMC 1.3

Question

Hi all !
I have a problem. I'm have a macbook pro Santa Rosa =
Model Name: MacBook Pro
Model Identifier: MacBookPro4,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB
Memory: 4 GB
Bus Speed: 800 MHz
Boot ROM Version: MBP41.00C1.B03
SMC Version (system): 1.27f1
This morning I saw the update for the SMC firmware (1.3).
Before restarting, I have this error :

Your firmware can not be updated because the hard drive partition scheme may not be supported. You must be booted from a GUID partiton or RAID scheme.
When I went into Disk Utility in order to check, here is what I have =
Name : FUJITSU MHY2200BH Media
Type : Disk
Partition Map Scheme : GUID Partition Table
Disk Identifier : disk0
Media Name : FUJITSU MHY2200BH Media
Media Type : Generic
Connection Bus : Serial ATA 2
Device Tree : /PCI0/SATA@1F,2/PRT0@0/PMP@0/@0:0
Writable : Yes
Ejectable : No
Mac OS 9 Drivers Installed : No
Location : Internal
Total Capacity : 186.3 GB (200,049,647,616 Bytes)
S.M.A.R.T. Status : Verified
Disk Number : 0
Partition Number : 0
I thought Boot Camp could be involved becauseI know it's the only thing related to the EFI.
I searched on internet, and Ifound nothing. There was a solution in order to reset the partition table, but the tool is no longer available. The link on on the application explains that I have to reformat my macbook pro. I find a bit weird to make this , I can't spend hours for backup / restore just because the SMC update does not work. have you any lead for me ?
Thanks ,

Have you tried this:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
