The card that is recommended is the one that works :-) Nothing over class 6 and I personally have had less luck with 16gb than smaller sizes. For me, a 4gb class 4 sandisk works best. For you, who knows? People are getting wildly different results with seemingly same specced cards.

I'm afraid it's a case of "suck it and see."
[Desire Android Development] RevoWution:
I'm gonna go and get a Sandisk 4gb Class 4 tomorrow straight after work. If that still gives me lag, then I'll be convinced that Data2SD and I just weren't meant to be :)
[Desire Android Development] Droidzone:
I feel for RevoWution.. Such a stalwart!
[Desire Android Development] RevoWution:
:D

Only because your ROMs are so awesome, and the technical support is top-notch ;)

If I get SuperNova working on the Sandisk 4GB Class 4 without lag, chances are I'll be utilising one of your other ROMs though, namely GingerBurst. I'm totally hooked on Sense 2.1 :p
[Desire Android Development] sibere:
Just a quick question. are u getting lags everytime or only when installing apps?

Personally speaking, I get slow responsiveness all the time on one of my "bad" cards. Even loading time goes from sub two minute to plus ten minutes!
[Desire Android Development] RoBy46:
I have 3 memoy card:

- Class 4 16GB sandisck

- Lexar 16GB Class 6

- Original card

date2 with all the rom to me to be slow, even with MIUI, with a good a2sd + go fast.

Excuse my English, I use google translate ;)

p.s: I have no lag in the flow of the home, but when I open applications, take a long time
[Desire Android Development] Droidzone:
I'm not understanding you properly. Are you talking about data2whatever or this particular Rom? What do you mean "Even with Miui"? We never designed anything for Miui
[Desire Android Development] RoBy46:
I mean, with data2sd, I always go slow, even with MIUI.

I hope to explain :(

Your ROM, without the data2 is very very fast
[Desire Android Development] Droidzone:
Miui is an aosp Rom, and all of them have issues with Data2SD. SuperNova/StarBurst ought to be faster.
[Desire Android Development] RoBy46:
Is true, it is faster, but with a2sd + is much faster.

I install more than 40 applications :)
[Desire Android Development] Droidzone:
Sure if you want only 40 apps. I need around 600 apps :D
[Desire Android Development] RoBy46:
You are crazy.....???? :D:D :eek:
[Desire Android Development] Droidzone:
One day I'll take a video of my installation, the number of apps it has and how fast it is! :D
[Desire Android Development] RevoWution:
With both my Transcend 16GB Class 6 & my Lexar 8GB Class 6, I get lag all the time. I'd get lag when scrolling homescreens, when I relocate/add/remove widgets and icons (typically a 3-4 second freeze time), when I open apps, and when I'm installing apps too.

The lag is so bad to the point where the phone is barely usable because everything keeps force closing LOL.

I have noticed very sparse moments where everything seems to "run as it should", and have tiny bursts of "omg this ROM is fast" moments, but that's only about 5% of the time :(
[Desire Android Development] Droidzone:
Visitor map for Supernova-

I'm flattered! :D

Time to take a nap!
[Desire Android Development] Yekxmerr:
Same here, and it happens with several GB roms. And i've tried different Sdcards.
[Desire Android Development] RevoWution:
What other GB ROMs have you tried? I've found the lag issue to be only with Data2SD-related ROMs.

For instance, I'm running LeeDroiD's Desire HD port which is GB as well, and it's fast as hell. No lag whatsoever. Provided it is only Data++ based though, and not Data2SD.
[Desire Android Development] Droidzone:
We've had lag isssues since Data2SD was in its infancy. At the same time, pioneers with good cards reported that it was lightning-fast. If only there was a screening test to seperate these cards, or a manufacturing index..
[Desire Android Development] RevoWution:
Back in business (hopefully) :)

Just picked up my Sandisk 4GB Class 4. What HBOOT do we need for SuperNova, dz? Stock HBOOT? :)
[Desire Android Development] Droidzone:
Ofc

[Desire Android Development] DroidBois:
Why would a larger card be slower?

Swyped from my Xoom
[Desire Android Development] RevoWution:
Many a late night and 3 SDHC cards later, I am still getting severe lag... :(

I guess Data2SD and I (my Desire) just weren't meant to be... Lol...
[Desire Android Development] schalmers:
For everyone looking for a good sd card. I have been using DZ's Starburst rom since it was released 5 or 6 months ago and have never had any lag or even 1 force close.

I have a Sandisk 16GB C4 Ultra, when tested it actually rates faster than most c10. The card is awesome...

I have yet to move to the new GB rom as I am on vacation but I don't expect any issues. I highly recommend the card to anyone looking for good performance and plenty of space with DZ's roms.

Aah..

No guarantees indeed haha... Thankfully those SD cards didn't cost TOO much here in Australia :P
[Desire Android Development] P0yraz:
hey guys again me!

I bought a new SDcard today and I partition it and now I put Supernova zip file in it but when I want to install it from phone it says No files found!

what should I do?! any idea?

it doesn't show even the folders :(
[Desire Android Development] booce:
Repartition the card, put the files on it again and try again.

Booce
[Desire Android Development] P0yraz:
I should install new windows and dot it then! thanks mate!
[Desire Android Development] atuladhikari:
U dont need to install "new windows"...

Use Gparted to format card to FAT32 n EXT4...

That's all...
[Desire Android Development] jigners:
Using Samsung SDCard 8gb class 4, initially fully formatted (fat32) with Panasonic SDFormatter 2.0 (IN PC)

then partitioned (in Device) using 4EXTRecovery = Very fast and stable ROM:p
[Desire Android Development] Droidzone:
Cool :)

[Desire Android Development] emanuel12:
I have installed it, working good here =)

One issue though. I didn't get the unlimited sd space... In other words I'm already out of space to install new apps =/

Did I do something wrong? Why isn't A2SD working for me?
[Desire Android Development] Droidzone:
I have nothing to do with A2SD!

If its Data2sd you mean, then use this to post:

duplicate post, sorry
[Desire Android Development] octa_amide:
I have been using Droidzone Rom for a long time.

Upgrade my SD card from 8GB Class 6 to 32GB class 10.

Transfer everything from old card to new card. Then just plug and play.

Been using the 32GB for two months now.

So far no problem.

Although I had the issue of Desire not detecting the card when I first plug it in.

Speed for Class 10 is not as fast as I thought. But it is still fast.
[Desire Android Development] Droidzone:
What brand is your card?
[Desire Android Development] black_astral:
thanks..nice rom u got..
[Desire Android Development] emanuel12:
So before installation I need format the microsd into 2 partitions.

How big should it each big?
[Desire Android Development] emanuel12:
Yes I mean Data2sd.

It seems I need to format the card before installing. I'm gona do it on Windows so I downloaded Paragon Partition Magic.

Any advice on the partitions size? Is there a minimum or recommended size?

Thanks Droidzone
[Desire Android Development] Droidzone:
It seems that you havent read the installation instructions at all. Read it fully before installing. I certainly wouldnt advocate partitioning on Windows..

http://supernova.droidzone.in/category/installation/
[Desire Android Development] RevoWution:
Don't partition in Windows...

Download the GParted Live CD, burn it onto a CD, and boot from it, then use that :)

SuperNova 2.0.2.0 on the anvil

SuperNova will be updated today!

===========================

11/8/11 SuperNova 2.0.2.0

===========================

[*]	Critical Patch: Bug which would cause system stalling with a Pink LED fixed-This Should fix first install issue that some users reported

[*]	Newer and better Wifi Update: Thanks to Myshkinbob for building, and Alex-V for sharing

[*] Typhon Updated to new version
[Desire Android Development] RevoWution:
Of course :) Lurking around, hoping you and/or sibere somehow conjure up a magical fix so that I can finally run SuperNova lag-free :D
[Desire Android Development] Droidzone:
Hmm..Maybe I could disable journal for you. Are you upto doing some manual edits. And you're finally S-off arent you?
[Desire Android Development] sibere:
No journal will give a little extra performance but may not resolve completely the issue.

Most important thing is to get an aligned fat32 and aligned ext4 partition, optimized fat32 format (see my thread op for this) and a well formatted ext4 of max 2GB.

This has always stated since the bigining of Data2SD.clearly explained in my thread op and in Droidzone installation instructions and faq.

Unfortunately some people don't take time to read completely those instructions, skip important informations and steps and then come and ask for support here. I can understand their eager but please read carefuly instructions and follow step before asking for support!

[Desire Android Development] booce:
I understand where you are coming from sibere, but I have read and followed all your instructions and I still have problems on 2 different phones and 3 different sd cards. Some cards just don't work well with your script and no amount of partitioning will fix that.

[Desire Android Development] Hilton.Swart:
Hey Dz, thanks for the awesome update,

Im just busy restoring all my apps now so will update you on how its all gone,

the only problem so far is the radio link on your site > the zip is somehow corrupt.

Tested atleast 3 different downloads and none will install, all have an error on line two.

Winzip also cannot read the file, saying that some data is damaged, CRC check failed.

Is there another mirror available?

Thanks again mate
[Desire Android Development] Droidzone:
I removed the radio link from my site after I found that it was not Edify compatible. You can get it at AdamG's radio thread
[Desire Android Development] Droidzone:
@booce, did you align your Fat32 too as per the instructions on Patriotmemory and linked by Sibere?
[Desire Android Development] emanuel12:
Nice :cool:

I read the instructions, I just couldn't follow it given that I'm on a Windows... I will give the live CD a try now

Thanks for the nice rom and prompt answers

well for incompatible SDs, there's nothing I (we) can do...
[Desire Android Development] emanuel12:
Where's the language Portuguese (Brasil)?
[Desire Android Development] sibere:
A more interesting test can be done with a (good) card reader and ATTO.

What is your card speed with small bits of data like 0.5Ko to 32Ko ?

Your phone will spend most of it's time at writing small random amounts of data than sequential writings like this test does. That's why some C4 or C6 cards are better for Data2SD than C10 cards.
[Desire Android Development] RevoWution:
What exactly is the journal? Haha.

What sort of editing am I tasked with? Hehe because if it's some sort of code, then I'm extremely limited, as I have no idea what's going on.

And yes, I S-OFF'ed with Revolutionary.exe a couple of nights ago when I had to RUU :)
[Desire Android Development] Droidzone:
I did make a patch for you, which has to be flashed just after Rom install, and before the first reboot. But if Sibere says it wont make much of a difference, he's right. You could try aligning your fat32 with the post from patriotmemory forum that is in his data2sd op. Plus making an MB aligned ext4 from Gparted. Then flash rom, followed by restart. Then restart again

The patch is attached here.
[Desire Android Development] RevoWution:
Thanks for taking the time to conjure up that patch for me, dz :) Appreciate it. Will give this a go some time this weekend.

And I'll also have a read about aligning Fat32. This is the article you're referring to right?

I'll probably try this method out with the Lexar 8GB Class 6 card first, and see if that helps.
[Desire Android Development] octa_amide:
yes, it will be interesting to find out. Will post the result for comparison after I am done. Its good to share this with other. Many people are not getting the right card and blame it on a good ROM(s) and "sibere???"
[Desire Android Development] sibere:
To keep it simple, Journal is here to guarantee data integrity in the event of a sudden loss of power like battery removal, hard reset or system crash.
[Desire Android Development] sibere:
I've done everything to optimze the Data2SD bit of code. I can take my share tho if it's not working but there is so many parameters out of my controls that I'd rather blame the SD or the installation process :)
[Desire Android Development] Droidzone:
True.. I still remember the time you first released, and there were posts all around the forums warning average users not to install it.. People have become so flash-friendly that they dont like to read anything more than a couple of lines! Not aimed at you Revowution.. We all know the pains you went through! ;)
[Desire Android Development] booce:
Ok, done some more experimenting with partitions on one of my slow cards. I formatted it with SD Format (https://www.sdcard.org/consumers/formatter_3/eula) which apparently aligns fat32 partitions if you turn the optimise to size option on. I then gparted and reduced the primary fat32 partition by a GB and created an ext4 in that GB. Stuck Supernova on it, flashed the phone, restored a nandroid of Supernova and the performance seems stellar!

Once SD Format has had a go at the card, I found that it had created 4mb of slack at the beggining of the card as well as a little slack at the end. I left these alone as I think they are what is aligning the partition.

Revowution, fancy trying that process with one of your known poor cards? It seems to have worked wonders for me.

Sibere, I may have spoken too soon, my humble apologies!

Hope this works for someone else.

Booce.
[Desire Android Development] sibere:
No worries ;)

The process of partition alignment AND filesystem alignment is essential and paramount on flash memory devices. From SD to SSDs.

The tool you posted is close to the Panasonic SD formatter to. It's optimizing the 1st partition and the FAT32 FS. You have to do the rest manually tho for the ext4 partition and filesystem :)

Happy that you're getting now good experience with the ROM :)

you can read quickly this post if you wanna go a bit deeper into things and understand what we're talking about .

ATTO Results

Well, here is my result of playing with ATTO.
[Desire Android Development] sibere:
Did you reformat the SD or is it still stock?

If you reformatted it using windows, you should do it again with the tool posted above and try again ATTO.

What is the block size on you SD card? 32K? 64K ?

EDIT:

Here is my SD which came with the Desire.

It's probably exceptional because my C6 doesn't get those hi scores tho.

I'm gonna test my C6 card and compare...

So 1st image is the C2 and the 2nd is the C6 card (the one i'm using ATM into my phone). This is tested obviously on the FAT32 partition and the C6 has 32K block size. I haven't found an EXT4 compatible bench yet ;)
[Desire Android Development] octa_amide:
@Revowution.

If you have the spare SD cards. I think is will be worthwhile to try the official SD formatted from the SD org or something.

My desire could not detect my new SD card when I first got it out of the box.

My 32GB Class10.

I found from the internet about formatting it with the tools. It is now version 3.0.

It found errors with my SD card which I did not expect.

My windows and Gparted were working fine. Using card reader, no problem or whatever. Detection and file copying were perfect.

BUT MY desire just cannot detect the SD card. "No card found"

Not even with fastboot or CWM USB mount.

I think I was cheated. But after I formatted it once. Or error corrected the SD card once. I formatted it again with Gparted. No difference felt.

BUT MY desire can detect the card. The full 32GB of it!!!!

I am using it right now in my phone. FAT32 with 1GB ext4.

Tried it and feed back please.

I hope can help a lot of people who are having problem with their card.

https://www.sdcard.org/consumers/formatter_3/
[Desire Android Development] Droidzone:
Great to hear that things are shaping up quite well!!

I'll have a go with the tool when I'm back home. My laptop's 40GB HDD is almost full and doesnt allow me to backup my 16GB card, lol... :D

Hope it works out for Revowution too!
[Desire Android Development] octa_amide:
Hi sibere,

so how do I interpreted the data?

I format the SD card with SD formatter.

It will take time for me to back up my SD card before I can format it again.

But will try again.
[Desire Android Development] octa_amide:
if the tool helps.

I think you should advice people to use it once in your guide.

Less unknown error so you can optimise your ROM better.

Thanks for your ROM.
[Desire Android Development] Droidzone:
Oh I almost forgot to say...

Latest Supernova is online..Fixes and new wifi driver are in..
[Desire Android Development] sibere:
The tool helps for the FAT32, but I'm not sure for the ext4, which is more important ;)

I still do prefer doing it manually honestly with the guide given in my post. But I'll post a link to this tool if it can help people :)

The data given is the R/W speed of your FAT32 partition. I doesn't reflect the speed you're gonna get on the EXT4 partition but it's a good indicator of your SD speed anyway.

I have posted an update on my previous post with ATTO comparisons.

Atto results of using SD Format tool

Hey all, here are the atto results from the same card, a Transcend class 6 16GB. The first results are obtained from the card being partitioned and formatted with gparted, 15gb fat32 primary, 1gb ext4, both mib aligned.

The second results are from the same card but formatted as one large fat32 with SD Format which was then resized with gparted. Reduced the big fat32 by 1gb with no alignment and then created an ext4 in the slack created, mib aligned.
[Desire Android Development] Droidzone:
I'll have a look
[Desire Android Development] RevoWution:
How does the card run with SuperNova? Any lag at all?

I've got the exact same card as you so it should be good indication as to how much improvement I should see compared to the first time I flashed SN :)

Thanks DZ :D Donor link works :D
[Desire Android Development] sibere:

[Desire Android Development] Droidzone:
Esp for read speed > 32K

Now to see how it translates into real world data2sd performance!

Booce, what about your incompatible cards? Is this on one of them?
[Desire Android Development] sibere:
Yep. But usually the bottleneck is write speed for small files, and his card is looking pretty good even on small files. above 1mb/s for 0.5Ko !
[Desire Android Development] Droidzone:
It seems as though post sd formatting, his speeds of 2-32K blocks seem to increase, while the ones more than that seem to decrease! :)

But of course his card seems to be great from the beginning.. I wonder if Atto on my card would be masked by the USB 1.0 port on the laptop.
[Desire Android Development] booce:
This will be the second incompatible card I've "converted" into a working one :D I've already converted my "bad" Sandisk 16gb class4 and that is running like lightning now on Supernova, which it wouldn't before. Before the SD Format revelation, I was getting startup times of 6+ minutes on the sandisk. Now it's slightly over 3. The ROM is now fluid and responsive on this card where as previously it was slow and laggy. SD Format has been like a miracle cure so far.

I'm in the process of moving to the faster Transcend I used in the tests I posted, I'm hoping that will be even quicker! I'll let you all know when I've tried it out.
