[Q] - Issue with /dev/block/mmcblk1p25

---

Hi xda community,

I've an issue with my Defy. My actual Rom is the last stable MIUI 2.3.7a.

The error is that the /data partition is always in read-only.

/dev/block/mmcblk1p25 on /data type ext3 (ro,relatime,errors=continue,data=ordered)

So I can't use any applications. ( lot of crash due to read only partition )

I have some errors like this one in the log :

Buffer I/O error on device mmcblk1p25, logical block 86151
lost page write due to I/O error on mmcblk1p25

I already try to re-install the rom and other roms included stock rom. And I always have this kind of error.

I have no idea on how to resolve this.

Can I move the /data to sdcard ? or use tools like fsck ? Or perhaps the defy internal memory is dead.

Thank you for help or advise.

Did you try full flash via RSD lite?

I'm late in my answer but this topic is always open in my mind.

Yes I try this several times, The flash work. But after a little time of utilisation (with stock rom or miui or cyanogen, the error occurs again.

I think that I have bad block on internal memory, my goal is now to create a partition on sdcard and use symbolic link to this one in order to bypass the internal memory. Or an easy way is to mount /data on the sdcard.

Actually I'm not familiar with Android, but I'm very familiar with Linux. In theory it should work if I can mount the sdcard early in the boot process.

Anyone have already try this ?

Hi,

Sorry to revival your post.

I have a similar problem (details in this thread). For some reason my Defy will not mount the /dev/block/mmcblk1p25 and I guess that's the reason why after each reboot all my settings are lost.

I've already try to Fix Permissions (under Recovery Menu > Advanced), but it didn't help.

I was hoping to learn with your experience. Did you could manage to fix your problem creating a symlink or something else?

Merci.
