I had this same problem. My memory card suddenly getting corrupted, but I managed to solve it. I believe the source of the problem is the Remote Lock and the Device Lock of the unit. I have an E63 unit (same as E71).
The problem started after I enabled the Device Lock and Remote Lock of my E63 unit. After a couple of hours, I tried to manage my apps in the memory card. To my surprise, it’s corrupted! I didn’t panic because I believe I could retrieve the files with my PC. But when I inserted my memory card to a memory reader into my PC, the card is unreadable. I had a feeling that the card is really corrupted. But how? I just got this unit almost a day ago. I didn’t do anything odd. I’m an OOP-Design Patterns oriented programmer so I’m not newbie when it comes to best practices.
As I searched the web, I found that there are cases too that had this same exact problem. And their guess is also the Device Lock.
So what I did is I disable the Remote Lock and the Device Lock. I checked my memory card and it’s still corrupted!
So, I turn off my unit and turn it on again, it’s still corrupted!
I removed the memory card while the unit is on (Make sure you use the remove memory card feature of your unit!!!) and then reinserted the card, and it worked.
In summary, to solve this memory corrupted problem: try disabling the Remote Lock and Device Lock. To disable the Device Lock, revert the password to “12345″ (Do not type the quotes). Remove the memory card (Use the remove memory card feature of your unit!!!). Re-insert card and problem fixed.
