As we reported a few days back, PS3 gamers that had installed the v3.41 firmware update were having problems after trying to upgrade their hard drives. Good news for those of you that were having problems as Sony has since released a fix.
The new v3.41 firmware adds very few bug fixes and addresses the issues with the hard drive upgrade problems.
The update is now ready for download, but don’t be fooled as Sony have kept the same name (or version) as the previous update. So just redownload v3.41 and it should solve any issues you still have.
