I can't see "sdcard" folder in Android emulator

Question

I have worked with the Android emulator and the SD Card without problem, but, I think that anything has happened with the last updates of Android, because, before, I could see the "sdcard" folder in "file explorer", but right now, I can't see "sdcard" folder in "file explorer" and I can't save any file, with the same application and configuration.

In my Android Manifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 <uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

My AVD has the next configuration:

And this is what I see on my "File Explorer". There is no any "sdcard" folder.

If I lunch the avd using the command line tools with the command:

emulator -avd em22 -sdcard C:\route-to-sdcard-image\sdcard.img

I can see in LogCat window next sequence of entries:

11-09 03:41:26.723: D/MediaScannerService(230): done scanning volume internal

However, in my File Explorer I can't yet to see the "sdcard" folder. And if I try to write in the SD Card I get the next error:

11-09 03:43:32.613: E/Functions(303): writeFile: java.io.FileNotFoundException: /mnt/sdcard/DCIM/BasketMonitor/2012-11-09-03:43:32-hola- (No such file or directory)

And If I try to push any file to the SD Card, I get the next error:

[2012-11-09 04:52:31 - ddms] transfer error: Read-only file system
[2012-11-09 04:52:31] Failed to push selection: Read-only file system

I don't understand anything!
