I'm sorry to hear that there may be a bug in this installation.
But I could not tell you where this behavior may come from.
Don't have any external SD's in the phone so I couldn't back check this.
As this is an stock kernel with a already known recovery and nothing special in it that could create such situation, I'm a bit out of answers....
But I will comment this for security reasons in the first post, to make sure that there are no more accident's like this.
To the point of CWM.
I choosed the Odin Setup for a simple reason.
It should be a good starting point for a stock user.
As a user without cwm recovery etc. you have to do quite some step's to come to the point where you can install the CWM version.
With Odin Version, you do only one step: Flash with odin, that's quit simple also for beginners.
And for the Recovery itself:
There are quite a bunch of different version out now.
I've choosed the one that I thought would be the newest one.
One may prefere FeaMod, some even Acro's Version (because he want's to test CM9 etc.).
You never can make everybody happy so I don't begin to try and did the Rom my way.
If you want to, you can use it, if not, im not angry.
Somebody here in the thead wrote, he has his base rom, it would be blaze-rom.
I'm fine with it, use what you want. I've done this rom for me and my wife in first place, so even when nobody other want's to use it, I'm fine with it
