[Q] sd card questions - Fascinate Q&A, Help & Troubleshooting

I'm a total noob to the fascinate, so i have a 3 part question about the SD card that comes with the fascinate.
1. Is there any improvement to, be found in upgrading to a class 10 card?
2. Can the SD card be formatted to say ext4 or is that what it is already?
3. Can I use windows to make a mirror copy of my old card onto a new one?

1- speedwise you would probably only see the difference IF you did an ext4 apps2sd (and the speed isn't that noticeable in such application)
2- i dont believe (but could be mistaken) that the roms designed for the fascinate untilize ext4 partitions for apps2sd
3- directly in windows you cannot clone an ext4 partition but you could buy programs to do so or just make a bootable Linux CD or jump drive.
btw I'm basing the ext4 reasoning as you wanted an apps2sd partition if not then there's no reason for an ext4 partition on your sdcard.

Thanx for the response.
I was mainly hoping that a class 10 micro SD would be better than the class 2 it comes with. If I go thru my apps and move them to SD, there is a noticeable slowdown on my phone, especially multitasking. When I move the apps back to phone it runs better.

[Q] Brought a new memory card, Now d2sd/Darktremor a2sd/swap?

Ok, so I brought a new 16Gb Class 4 microSd card and I am going to partition it. I was wondering how much should I allocate to each partition type?
1. How does 14gb fat32, rest ext2 sound?
2. Should I leave any space for swap?
3. Also, out of Darktremor a2sd and Data to sd with dalvik-cache to ram, which one should I use?
4. In case if I upgrade my rom, do I have to re-enable them and copy the stuff again? Hows their compatibility with regard to upgrading?
5. Performance/drawbacks?
Thank You.
Also, does it make a difference which one is partitioned first?

It's mentioned that EXT2 is to be partitioned first but,
Here: http://forum.xda-developers.com/wiki/index.php?title=SD_card_partitioning
Fat32 is partitioned first.
make Fat32 first if you want sd card to be recognized by Windows... if ext2 will be first, you cant access second partition on the SD card...
What about Swap?
Guys I made the partitions as said but the phone says damaged sd card. But if I format by phone, it runs ok. Any idea?

[Q]How to partition SD?

I've read a lot about Ext2,3 and 4 partitions, Swap, Fat32 primaries, etc.
I don't understand any of it and I can't seem to find any explanations.
Right now I'm running Vipermod's ROM but I was going to flash Synergy until I saw that it seems to require partitions to be set up in some particular way?
Any help would be appreciated.
you can do fine with the way your card is set up now, no extra partitions required.
If you have a fast card, you can partition it to have what most call SD-EXT. my understanding is that its used to store applications automatically with A2SD ( apps to SD ) you can also move swap and dalvik-cache to the SD card, but only if its fast enough. Class 4 is recomended. but most say you shouldnt waste it on a class 10 since the evo doesnt use that much speed.
EXT 4 is supposed to the format for sd-ext or the dalvik. fat and fat 32 are for everything else, so windows can read the SD card.
ext 2 and 3 are the previous formats, but ext 4 is faster, but not always supported. ext 3 is the most common

[Q] EXT2 format partition on SD card

i want to change my sd card partition to ext2.
i already did, matter of fact, but the phone did not recognise it.
i am on stock GB bb 71.
how can i get the phone to recognise the card in that format?
i thought that GB enabled the use of ext partitions natively.
r u tryin to format ur sd card to ex2 to use link2sd?
not really.
i just prefer having ext filesystem, as i am a ubuntu linux user, and i know that performance wise, ext2 will be better than FAT.
i would also want to discourage my brother from plugging my phone into his windows laptop in the name of getting stuff and leaving viruses on the card.
Or you will use link2SD with 1st partition in Fat 32 (more 2go) and Fat (2go or less). The 2nd partition in Ext2.

Request/Search For SD mod

Ok so far Ive found the mod to swap the internal and external sd,
The ideal mod for me is to merge all the 16gb internal into one partition and mount my sd card as a normal sd instead of external sd.
If anyone knows of the mod to do it the way ideal for me please link me. If you are a dev and like this idea would you take the challenge to make this happen? I will gladly beta test as long as a fastboot is available.
You want volume management on a phone?
Just get a big honking SD card. I have a SanDisk 64GB sdxc.
The 128GB cards will probably be available by October.
That said, you can probably get LVM working under Android, but you'll only be able to work with it from the phone itself (no browsing from a PC or putting stuff on the microSD directly w/o totally breaking the logical volume).
You can also format the SD space as ext3, then set up /etc/fstab to mount the external SD on a folder on the internal SD eg, /mnt/sdcard/Music Library. You won't be able to read/write that space from Microsoft (no, e2fsd won't do it), but any other OS can browse it like any other disk drive. Also, the drives will still appear separate from outside the phone.
the ext3 sounds nice but I like my idea better, my idea is pretty much the way samsung/htc/lg formats their storage, one is phone storage, other is sd, not the phone, sd (other internal) and extended sd(actual sd card)
and sorry for some confusion for anyone I meant Extended sd not external, kinda a noob in here coming from a sammy prepaid android.
Iirc in ICS the internal memory is counted as one part. So the 4gb and 8gb will be 12gb or whatever. Android 2.3 and below use the partitioned method.
Sent from my XT910 using xda premium
Edit; therefore wait till ICS comes out

[Q] SD Card Partition Problem

hi guys,
I partitioned sd card ext with 1GB with FAT32 using mini partion tool
when boot ON the Phone & using with LINK2SD Main sd card & ext sd card showing the same size of 1GB ....
is the problem with ROM ??
I tried with another sd card but the issue is same
i'm using stock rom & 16 GB Sandisk C10 sd card
Pls help me......
Link2SD
The XPERIA X10i running GB 2.3 is a bit problematic with partitions.
The OS only mounts the first partition it finds and that's normally the second partition. Doh!!
The following patch may be of some help to you
SE2.3.3-link2sd-patch.zip
It is assumed you have formatted both partitions as primary.
Everybody should use Link2SD if they have an XPERIA X10, just because most quality class6/class10 cards have better read/write speed than internal flash and with a 1-2GB sdext2 partition more space too.
Considerations
I'd format the second partition as ext3 and 2GB if Link2SD is to be used, especially if a gamer.
I would only use a class6/class10 'quality' 32GB microSD card or greater.
Copy the contents of the /data/sdext2 partition to a NAS/external server
(1) I'd format the partition to be used with Link2SD as ext3 ( I've found on my builds I can't use ext4, but would, if I could ), just because it'll give better performance. In a gaming environment 1GB can be used up pretty quickly if libraries and data are linked too.
(2) The cost of quality class6/class10 microSD cards has really dropped in price now that extreme and extreme pro cards (50MB+ write) are all the rage. It's just a pain having to rebuild a working Link2SD environment onto a larger card at a later date, when a lesser card, no longer meets needs.
But given I'm using a 64GB card, I would say that.
(3) If you copy the contents of the second partition to a linux system /folder it makes a great recovery, as you only have to restore the Link2SD second partition and you get all your apps back, data and all. I copy my /data/sdext2 partition onto my NAS every now and then and it has saved my bacon a few times when microSD/SD cards have gone belly up.
