FS#11840 - PANIC* SD Xfer read err:0x8 Disk1 with uSD 32GB in Fuze v1

In my Fuze sansa V1 0781 74c1 Sansa Fuze (MSC), when I turn on the device, I get a lot of *Panic* always i made something on the sd card.

The error:
SD Xfer read err:0×8 Disk1”

my uSD Card: kingston 32GB microSD HC Class 4
Rockbox 3.7.1 and r28903-101226.

No problem with Sansa software up to 2GB and it is ok on windows xp.

Appears to have been fixed by r29746. See also /index.php?topic=26852 . If not, please request a re-open.

Can you try these patches?

Patch amsv1_sd_normal_speed.patch disables high speed mode. It looks like the command sent to the sd card to enable high-speed mode is not done completely properly.
So if this patch works, we probably know what is causing the problem. This will probably cause the sd card throughput to drop by 50%.

Patch amsv1_cmd6_delay.patch keeps the high-speed mode, but adds a 100 ms delay as a workaround. This will have no impact on the sd card throughput.

Patch amsv1_cmd6_delay.patch has been committed and fixed usd detection problems for someone else.

Please try the current build and verify that this fixes your problem.
