Re: More 240gb drive issues

Hi,

(fullquoting because the thread is nearly 1 year old ...)

I just did that, and noticed that for the MK2431GAH, MAX_PHYS_SECTOR_SIZE
needs not be set. I commented it out and just defined HAVE_LBA48, such as:

--- rockbox-r24769/firmware/export/config/ipodvideo.h 2010-02-19 08:59:36.440434460 +0100
+++ rockbox/firmware/export/config/ipodvideo.h 2010-02-19 09:17:25.908432186 +0100
@@ -213,7 +213,9 @@

 /* define this if the hard drive uses large physical sectors (ATA-7 feature) */
 /* and doesn't handle them in the drive firmware */
-#define MAX_PHYS_SECTOR_SIZE 1024
+/* #define MAX_PHYS_SECTOR_SIZE 1024 */
+/* #define MAX_PHYS_SECTOR_SIZE 4096 */
+#define HAVE_LBA48

 #define BOOTFILE_EXT "ipod"
 #define BOOTFILE "rockbox." BOOTFILE_EXT

The patch works fine against a recent SVN snapshot (r24769). The iPod Video
5G I have has no probs with the large disk USB-wise,

Now if that works for everyone I don't know (and can't check) but you folks
with a desire for large disks may give it a try.

Hope this helps :-)

Ciao,
Harald
