[WIP] UMS/MSC storage

First off: UMS/MSC is USB Mass Storage/Mass Storage Class
This is something I've been working on. We don't have UMS. And, I want UMS. Google/Samsung's reasoning was they didn't want to make us choose between internal storage for apps, and external storage for music.
The one flaw that comes with this is that we lose UMS. UMS requires a block device that can be unmounted from the phone and mounted to the host machine (Windows/Linux/Mac).
We can get this back relatively easy I believe without re partitioning our phones. I don't want to play with partition tables, because there isn't an easy way that I know of to restore it to stock.
To get technical: /sdcard on the Nexus is just a symlink to /data/media. We can break that symlink, modify the fstab and init.rc to mount an image file to /sdcard, then modify vold to allow us to mount that image file to windows. The downside: we'd lose what google/samsung thought was an amazing idea: not making us choose between sdcard storage and internal app storage.
I guess why I'm posting this: is anyone interested enough for me to actually do this?

What exactly is the benefit? Could you explain?

Sounds like a ext but to the sdcard instead of the data partition..
Sent from my vzw Gnex.

sounds interesting! the convenience of having UMS is definitely missed. as long as everything functioned "normally" I'd do it.

Yes please! Especially if u can do it so that it'll also work in clockwork, might be easier. It would make everyone's life easier, and I bet a lot of devs would end up baking it in to their roms!
Sent from something, using something, from somewhere!

If I am reading this correctly this would essentially make that folder act like it would under an external SD card meaning once I mounted it to windows I would lose all access until unmounting it from windows?

More options are always good, but honestly I've gotten used to MTP and not having to mount and remount as well as not having to worry about swapping between internal storage and sdcard. I say do it just so we have options as users, but I'm not really sure I'd use it over the current methods.

You got it. You could even use the folder as /sdcard and programs wouldn't know the difference.

This would be very very nice for Linux users as mtp can be a pain to transfer files with. And adb isn't exactly the fastest for large files.

Yes pleaseeeeee!!!!!!!

You should work for Google. I think that's how they should've shipped the phone.

Great idea. That would make device recognition much easier in Linux. It's a real pain trying to get it to pick up GN on Debian. If you get it working maybe I can have your permission to use it in my git for my rom compilation?

Be nice, current method with Macs is painful.

[Q] How can I free up some ram/memory on Windows XP

Yes I know xp sucks arse.... unforturnetly I have to deal with it...
Anyways how would I go about getting some freed up ram or memory because I need to clear out some junk and rather not take a shot in the dark and end something dangerous. So any suggestions other tan get windows 7 will be greatly appreciated I know disk cleanup and defreagment are useful but is there anything else?

I haven't used XP for a while (other than at work, where I am not responsible) but, I think Start -> run -> msconfig.msc might help you out. You can disable anything you want during startup. You can probably also tell what you are disabling because it will tell you the path to the executable. After turning a bunch of stuff off, reboot and see where you are at.

I am sure you already know this, but virtual memory is much, much slower than hardware RAM. That said, increasing virtual memory probably won't speed up your system, but will allow for additional multitasking (running more programs). Windows does a pretty good job at managing the virtual memory and keeping the more accessed information in real memory.
In short, I don't believe that increasing your virtual memory will make much of a difference. 2GB should be plenty. Additionally, if you are using a 32-bit version, Windows can not access more than 4GB of RAM (including video RAM, and hardware RAM) and that limitation may include virtual memory. Typically, 3GB is about all you can use with a 32-bit OS.

The task manager... right click on start bar (not on a button or application) and start taskmanager. All applications have an associated process but not all processes have associated applications (at least applications with a GUI). From the process list, which will have what you want to get rid of, you will probably have to google each process name to determine what it is and how to get rid of it and if it is safe to do so. When I do a fresh XP install with anti virus and a minimal application set, I have somewhere around 40 total processes.

That looks pretty good. One thing to remember is that "cached" physical memory is almost free memory. The operating system has files and other data that is cached in RAM for quick access but can easily be dumped to make room for new information.
So, now the question is, what is the problem/symptoms that you are trying to solve?

Msconfig is really meant as more of a trouble shooting tool. It's not proper to use it as a maintenance tool. If there's anything that you want to disable at startup you really ought to handle it in that particular programs options. Or consoder uninstalling tje program entirely.
Better than the stock windows defragment is a program called defraggler.
Also, you might try a windows XP forum. I think they would be better help.

Well according to y'all its not my memory I guess I'm running the cpu more than it can handle its a guitar program in basic terms it turns my computer into an amplifier if you need to know its POD Farm 2 and when I try to add a "dual" which is like using two different amp setups it chops the sounds and won't work correctly and was thinking it was my memory not being able to free up the needed ram but I guess my lil 1.3ghz cpu isn't cutting it

There's 'natural' fragmentation of files that happens over time that a defrag'er can't always fix. A clean install is kind of like the ultimate defrag'er in that sense.

Since I had such good results last time I posted about a pc I was wondering something else.
My mother uses her pc for work and it requires certain system files that work like a network or a passage to her works servers. Something in system32...idk anyways... I was wondering if it were possible to image her pc and flash it onto the new pc I'm going to be getting. If not She really just needs xp on it and needs internet explorer 6 and her word 2003 it has a lot of auto corrections/ shortcuts in it. The system files can be put on it by her tech support. Basically she needs xp on her new pc with her internet explorer 6 and word. What would be the easiest way to do so?
I know I could find internet explorer 6 somewhere.
Also for the word I could transfer the auto corrections to the newest word 2010 but I hear it has to be done for each auto correction and she has upwards of 500 hundred.

USB file transfer from pc problems

Hi all, I have been having this problem for a while and now i am tired of it. For sometime, when transferring files from my pc with win 7 to the my phones external sd, its moves really slow. the progress bar, time remaining and speed all moves very slow. When using any other devices it works correctly so i know its something with the epic. For instance, it may say its going a 1mb per second but it sits there and about every five or maybe even more seconds, it updates the speed or time remaining but shows barely any progress...

Do you have the official drivers installed? And dumb question is it a high speed USB port (2.0+)
Sent from my SPH-D710 using XDA

It could be related to the speed of your card, the quality of your cable, and even which usb port you use. Or a combination of the three.
Try changing one of these, especially the cable or usb port and try out an app called sd tools. It will give you more information about actual read write speed to your card.

System memory

I've been curious about this for quite some time now. Our phone has 768mb of total ram space. I've noticed AOSP roms allow 602mb to be used and Sense gives 573mb. Is it possible to substitute system memory for ram enabling more free ram for our device?

Substitute system memory for ram? You mean like a pagefile on windoze? Or just freeing up more ram? Not really following what you mean.

Ok I know "x" amount of ram is required to run a rom. What I wanna know is can any of that be transferred into say the system memory so that instead of having only 573mb of 768mb we could have something like say 625mb of our 768mb? I guess I should of clarified earlier.

Yes like vm in windows. So it wouldn't speed up our phones if this was done? That is what I was trying to accomplish by all of this in the first place. I figured if I was able to make the RAM larger in size overall that would in turn allow bigger apps to run smoother. I know there's a lot more at play like processor speed and kernel but its just a thought

Haven't really looked at it, but it depends on whether we use up all the RAM often, and I don't think we do.

I think NO.. we can only adjust CPU frequency though

My knowledge of linux is very limited, but I think that you are thinking of it too much like Windows. In Windows more free ram means better performance. That is because Windows doesn't kill processes that aren't being used when ram is needed, instead it uses vm to allow the program to run.Android will kill processes that aren't in use if additional ram is needed so vm is not necessary. This means that performance isn't really effected by free ram.
Someone please correct me if I'm wrong here.

No worries. I think most people here think the same way because most of us use Windows. I wouldn't have known differently if I hadn't read it previously on here. That's the same reason why task killers are bad.

Android puts background processes that arent running in the foreground in cache memory, that way it's not eating up ram like if it was still running but since its in the cache, if you open the program though it will still come up quickly since it is cached, only certain programs that are frequently used are like that though...
