<p>created a Disk Mode page</p> <p><b>New page</b></p><div>Disk Mode is a binary that serves two purposes: first, it exposes a USB Mass Storage and SCSI device to provide access to the iPod&#039;s filesystem. Second, it facilitates the recovery functionality of the iPod. On the Nano 3G, it is stored on NOR Flash.<br /> <br /> This page currently focuses on the Nano 3G&#039;s Disk Mode unless otherwise noted.<br /> <br /> == Memory Layout ==<br /> The memory layout of Disk Mode is far simpler than that of Retail OS. See [[RetailOS#Analysis_.2F_Memory_Layout|analysis of Retail OS&#039;s memory layout]] for more details about how this relocation process works. There are only two sections that get relocated:<br /> <br /> {| class=&quot;wikitable&quot;<br /> |-<br /> ! Name !! Memory Address !! File Offset<br /> |-<br /> | sram.text || 0x22000000 || 0x00000000<br /> |-<br /> | dram.textdata || 0x08000000 || 0x000051f4<br /> |}<br /> <br /> == Known RTXC Tasks ==<br /> There are several tasks in Disk Mode that RTXC manages. These are inferred by the presence of string names for these tasks:<br /> * HostOSTask<br /> * USBDeviceTask<br /> * ATAWorkLoopTask<br /> * ATAWorkLoopIRQTask<br /> * CNATask</div>
