As per old specification (SD Spec 2.0 ) Maximum size of SD memory card is= 32 GB. - We used ext2 file system. By referring the new Specification (SD Spec 3.0) SD memory card size is r= eached upto and including 2TB (Terra Byte) - Block size strictly limited to 512 only (as per specification). My Questions. 1. For 2TB disk with Block size 512, Which file system is preferred (ext3= /ext4) 2. In a 32 bit machine, If I installed the Fedora 10 ( having ext4), am I able to use it as effectively ( for the maximum disk/file size usage). To utilize 2TB or more size hard disk, is this allowable to use 32 bit ma= chine with Ext4 fs? Thanks in advance.
