About Swap Memory

Hi comunity!
Well you'll see, I will try ro explain the best I can, because I still don't dominate the English language, so here I go.
I'm from Mexico city and I have an Xperia Arc S LT18a when I brought it, the device come with GB 2.3.4 so I read a lot and then I could flash without fear a "clean" firmware and then I could upgrade to ICS so, my device is locked bootloader, but it's rooted and with CWM I've played some time with the Fw 431 and proved mod roms for stock, in this moment i have the Fw 587 and the doubt I have after all the story nobody wanted to read is, that when I was in 431 and I checked the memory status with SetCPU the section with swap total and swap free always was in 0 no matter if I was at stock Fw or in a mod rom, and now I don't know how magically I have data using that status, and the point it's that I just have Fw stock 587, a few apps ported from Xperia S, MicroSD Adata 32GB class 10 partitioned with 29GB fat32 & 1.91GB Ext3 for using with Link2SD (1.87 after the formating process, and 1.74 it's what Link2SD has recognized or assigned after mounting the partition.)
Rooted with the downgrade kernel proces and flashed back the kernel, the same configuration when I was on 431 and never saw any movement on the swap memory. This could be a new benefit of the new characteristics from Fw 587? With this I think could be possible to use swapper for make a 256mb file swap for use it? Somebody had noticed this too or this is normal and i'm a total nooby asking stupid questions? Btw when I was preparing the device to kernel downgrade, flash tool detected that was busybox 1.84.5 already installed, and I was just about to begin to move the guts to my phone.

CM11 and any AOSP-based ROMs cannot have move 2 SD feature because the Nexus devices which AOSP is based for do not have SD card slot. You can use Link2SD and GL2SD. Link2SD requires you to repartition your SD card.

yep try to format it to exfat or fat32..

And how to do that? Never had ext sd issue entire life,just this one only
Sent from my GT-N7100 using Tapatalk

take the SD card out and put it in an SD card reader that you can plug into your PC (usually via USB)... then right click it and format.
PS
good format allocation size for exfat is 128

Can't mount /storage/extSdCard after partition SD Card CWM NOT WORKING AT ALL

Hi, I'm hearkenoath and I have to bear with a Galaxy Fame GT-6810L ;P Not complaining so much recently though.
I partitioned mi 32 GB SD class 4 Card Adata (if the brand helps) using Mini Tool Partition Wizard Home Edition like sayhellotwoheaven posted http://forum.xda-developers.com/showthread.php?t=2126363 I followed his steps and numbers. Even though I knoe that partitions should be only 20% of the total space.
And I know, I know: maybe our kernel doesn't support EXT4. I'm using Corsifame ROM from this forum but the perfomance was pushing me to smash my device against the wall. So I was interested in swapping virtual memory AND I KNOW, VM has a reduced number of R/W cycles and potentially can fry my SD/internal storage.
I used this helpful thread http://forum.xda-developers.com/showpost.php?p=50143050&postcount=101&nocache=1&z=8882311745546758 and set it up to full ZRAM usage and Swap partition (since the other options don't worked for me)
The result was superb, so much better that before or with the 32 GB card not partitioned but the space ended in 9.99 GB only readable trough the phone and with the Kies installed.
My problem is this: the SD card cant mount, obviuosly I can't flash zips from CWM (only using /sdcard0) or backup and that stuff. I tried umount /storage/extSdCard/ and mount/ from CWM. Also can't cd to that directory (but I feel like never can't)
What can I do?
My root was with VRoot if helps. I appreciate all input.
P.S. I followed this tutorial and got Backtrack 5 running in our humble device. I always thought that my device would freeze

Sd card bug?

Hi!
I've updated my z1c to lollipop recently and I've occured a bug. Phone doesn't 'see' (recognize maybe?) my sd card I don't know what to do, it's annoying, but when I put out my card and put it right back in it shows me the access. The funny thing is that I can play songs in Walkman and I can see photos, but when for example I connect my phone to PC it shows me only internal memory. Anyone have the same thing?

I have the same problem , access to internal SD card denied with preerooted 270 rom. I had the same problem with Nordic and Baltic Had to go back with nandroid since phone was kinda useless. I guess the solution is really simple and hope someone smarter can point us in the right direction.

I really hope so, 'cause it's annoying
