Hi Everybody I'm sorry if my question sounds absurd to some. I've found out through web sources, for the following reasons/features we need libata, [1] libata is a library used inside the linux kernel to support ATA host controllers and devices. [2] libata provides an ATA driver API, class transport for ATA and ATAPI devices and SCSI<->ATA translation for ATA devices according to the T10 SAT spec. [3] libata causes each SATA to appear as a SCSI bus. [4] It controls how the low-level driver interfaces with the ATA and SCSI layers. [5] libata supports the necessary "lba48" ATA addressing extension starting with kernel version 2.6.5-rc2. [6] libata has hotplug & random task file submission(thus enabling SMART support). SOURCE KEY:[1][2][4]libata.pdf [3][5][6]http://linuxmafia.com/faq/Hardware/sata.html But still at the back of my curious mind I'm looking for the most appropriate answer to this question that can come only come from the experienced linux kernel experts of this group. Now some info about myself, i'm a software engineer in india and developing GPL'ed (open source and Linux Kernel 2.4 based) SATA low-level driver for a SATA/ATAPI-6 Host Controller on a ARM 920TDMI based chipset. Looking forward for your replies and guidance.
