Question [Q] CWM cant mount external sd

I'm on Thunderzap kernel 3.0, with CWM 6.0.3.5. Whenever I try to make a backup to external sd, or try to mount ext sd card, cwm says its cant mount external sd. I have done this earlier on old ROMs. Currently on 15.3.A.0.26, (android 4.2.2). Phone is rooted, BL unlocked.

Given below is the recovery.log after trying to access "Backup to External sd" and "Mount external sd".

I think the primary reason for failure is log claiming that the filesystem on sd card is non-vfat. However, the sd card was formatted by android itself. So it must be must be fat32, and yes, it is - I mean, I didnt touch the card's partition or format it outside the phone.

Weird thing is that Gparted shown my 32 GB Sandisk Ultra (Class 10) card as Unallocated space (while it was mounted). Yet the phone mounts the card in mass storage mode and I can read/write.

Code:

DONATE TO ME
I guess that option is not available to our CWM yet. I couldn't mount it too , even formatted the mem card once. Just place your stuff in INTERNAL STORAGE or just SIDELOAD FROM ADB

Yup There's a THANKS Button Hit IT!
