I recently posted this question on OnePlus forums and it was immediately closed as if I was out of my mind. One of the respondents posted a link to Wiki which explains difference in HD sizes etc but I nobody really answered my question. So I come back home, and ask those in the know.
I recently tried to install AOSP on my OnePlus but it wasn't going so well, so I restored my phone to stock using Fastboot. I was sure to use Userdata_64G.img instead of Userdata.img but my device is still reporting it only has 54.87GB instead of 64GB.
Can anyone help me resolve this issue ?
If you have an unmodified OnePlus, can you please let me know what Android is reporting as Total Space under Settings > Storage ?
It just seems odd to me that I am missing 10GB as Cyanogenmod 11S is pretty small. I couldn't even imagine what a 16GB model would report if the other answer on OnePlus forum, "Some of that storage space might be required for the OS to run", is really correct.
Thanks for your help!!
Thats intended. If you read closely on the OnePlus box it says, Actual usable capacity may be less due to formatting, system files.
Its the same thing when it comes to hard drives, solid state drives and other mobile devices. Whats advertised is not what you get.

I completely realize that HDs are often sold with different sizes than is advertised. However; 10GB difference ? We aren't talking about a 500GB drive which is really only 485GB...
And if that is true... Does a 16GB OPO report only 6GB Total Space ?

No, the 10GB is not fixed. According to a search on Google, its about 12GB. My N5 16GB has 12.58GB as well.

Yikes, a total noob about everything related to computers?
The bits first have to have a filesystem created, typically ext3 for Android which has overheads of creating directory structures, permissions, users, etc. That often takes about 1% minimum to 5% typical, just to be able to write a file.
My Linux desktop I'm typing this on has a 128GB SSD which has 118929676 1KB blocks so has lost 12% due to the filesystem, and the journaling which allows a recoverable data in event of forced shutdown.
Then there is the partitioning. Here is my OPO's output from the df command
Code:

/dev 1.4G 132.0K 1.4G 4096

/storage/emulated/legacy/Android/obb 54.9G 24.4G 30.5G 4096
Some key areas are /system for OS files is 1.3GB, /cache for performance and temporary files is 504MB.
/data is for your own stuff which you see is 54.9GB.
Hence 64GB - 5% = 60.8GB (minus filesystem) - 1.3GB OS - 0.5GB cache = 59GB , then take away a lof of the other filesystems and you're getting to your 54.9GB.
As to the lesson learned? Well don't buy a small storage phone as the meer running of Android is taking up a lot and what's left is for you and so a 16GB phone would have very little left. So some idiot fool noob might think 16GB has 25% of the space of 64GB. Wrong! It has much less.
My understanding is ART takes up even more space as it pre-builds and has a cache?
OS tend to get bigger too, the constant battle with bloat.

That is correct, ART takes extra space. Kudos to OnePlus for having the difference between 16GB and 64GB in terms of price be only $50 whereas other manufacturers would charge you $100 for the extra storage upgrade.
Not much bloatware on the OnePlus One either so thats great as well.
http://en.wikipedia.org/wiki/Gibibyte
You are bit pf noobs, sorry
Listen carefully guys.
What is usually shown on phones ads and pen drives or hard disks are in gigi bytes(Gib). It consists of 1024mbs. But our phones are actually in gb with 1000mbs.Now the settings app displays it again in gigi bytes.
Now the maths
64gb(remember not gib) is 64000mbs
64000mbs is 64000000kb
Which is the actual space in our phones.
Now if we divide it in gibs which gives
64000000kb into mibs that is 64000000÷1024 is
62500mibs now that into gb becomes
About 59gibs
Now
The rest is taken by the system.

A month ago I ordered this item:
http://www.amazon.com/Lexar-MicroSD..._m=ATVPDKIKX0DER&pf_rd_r=1PQ8JS4R3GMEAF3KKA5X
Yesterday it arrived, a 32GB, Class 10 MicroSHDC.
Previously I had a Sandisk 16GB Class 2.
Today I'm gonna try it on my Nexus One and keep this thread updated regarding my experience with this card.
Let me post ATTO test result screenshot first
4 May 09:10am Partitioning it, 256MB swap, 2GB ext2, rest = FAT 32
4 May 09:24am Done an ATTO test on my old Sandisk 16GB Class 2 and upload screenshot
4 May 09:27am Preparing for a complete wipe on my Nexus One. Re-format 32GB card using 32KB allocation unit size. Using Windows Explorer to copy and paste music into it, speed is around 9.9MB/s
4 May 09:33am Writing is very steady, at around 9.85MB/s. Finger touched on the card, it's very hot I'm using Lexar card reader (which came with the card).
4 May 10:19am Just cleaned my phone (physically ) and copied lot of music into the card, gonna put it back into phone and do a clean wipe
4 May 10:59am System boots fine, configuring settings, no noticeable boot speed improvement since I have not installed any app yet.
4 May 11:13am Noticed that the phone's speed of installing & downloading multiple apps at once has increased significantly.
4 May 11:29am Installed about 30 apps system runs smoothly, no any problem so far.
4 May 05:19pm Has been running the phone for half a day, noticed no battery consumption difference, the SD card is stable.
5 May 18:25pm Today I installed more apps (185 in total), and started experiencing serious performance problem, system stuck when listening to music and installing multiple apps. Re-partitioned the SD card into 0 sawp, 1.2GB ext 4 and rest is Fat32, still using 32kb as allocation unit size. I'll see if the issue gets solved. By the way, the battery consumption of the new card seems to be equal as my previous Sandisk one.
6 May 08:47am After re-formatted the card last night and updated to the latest CM nightly, IR's kernel and Gapps, the issue seems to be little better, although it is still laggy to install more than 10 applications at once however the phone does not freeze anymore (so far). Probably 2GB ext partition was too big for DT app2SD?
8 May 10:03am Everything seems to be very stable and fast, partition configuration is: 1.2GB Ext2, 0 Swap, rest = FAT32 using 32KB file allocation unit size, have more than 200 apps installed now.
9 May 15:47pm Well, after installed totally 300 apps yesterday, the system has been not very responsive, applications often lose response and come back after a while, Market app sometimes lose response and crashes, system is pretty unstable. I was on Nightly #64, IR's 0506 kernel and Gapps 0503. I have just re-partitioned the SD card again, trying 1GB Ext2, 0 Swap, rest = FAT 32 and use 16KB as file allocation unit size. This time I'll use CM stable 7.0.3, IR's 0507 kernel and Gapps 0301, see if everything becomes OK.
10 May 13:15 Really tired of re-installing system for more than 4 times in just one week. The card initially performed well but now it just can not handle App2ext, Market app keeps crashing, application forces close and system reboots automatically multiple times every hour. But I don't plan to give up and go back to my old 16GB card yet, I'm seeking for a solution and I'm confident that Nexus One can handle a 32GB sd card.
11 May 09:00 Yesterday I thought about changing the partition characteristics. Eventually I formatted the card into 1.2GB Ext3, 0 Swap, rest = Fat32 using 64KB file allocation unit size and now the stability issue seems to have been resolved, no more force closes or system reboots. Is it the key that 64KB allocation unit size resolved the issue?
11 May 20:00 I've just re-installed (I can't remember how many times I've done this in the last 10 days) system, did a clean and complete wipe and re-partitioned SD card into 1GB Ext3 and rest = Fat32 using 64KB file allocation unit size. I feel like the reason of instability is now determined. Now I'm installing apps and will report back later on stability and make a conclusion with this Class 10 32GB card.
12 May 20:03
Now I can make a conclusion on how to correctly use this card on Nexus One.
There are two factors, which contributed to instability of my previous installs, one is CPU voltage, another is partition layout.
The new card seems to use a bit more voltage to work, that's why my phone became unable to use (reboots and FCs) after I applied my own voltage table (undervolt 100mV at each frequency compare to default table) with IntersectRaven's kernel. The card works fine with the default voltage table of IntersectRaven and CM's kernels.
However, that's not all.
Why the system was very unresponsive when installing many applications, and simple multi tasking would completely freeze the system? Another factor contributed to the issue: File allocation unit size. From the speed test screen shot we can see that the card achieves its best performance when block size is 64KB, that indicates that the card internally is formatted into 64KB blocks. I am still not sure why using 16KB or 32KB file allocation unit size for its FAT32 partition will cause system to be very unstable, however after using 64KB as file allocation unit size, the system runs very smooth and stable, now I'm happy with the card's speed and quality.
Current partition layout:
1 GB Ext 2
0 Swap
Rest = FAT 32 using 64KB as file allocation unit size
18 May
Re-partitioned into 1.5GB Ext2 (1GB was not enough for 400+ apps) and rest=FAT32, still using 64KB as file allocation unit size.
The card has been stable and noticeably fast with more than 400 apps installed.
9 Aug
This card has corrupted for about 7 times due to rapid random accessing by phone, and proven unstable for daily use. Do not use this card on your phone if you have more than 200 apps installed on Ext partition!
See this post for more details:

Good review!
Nice review.. I'm thinking of getting 32GB class 10 myself this'll help me lots.. hey can you tell me what speeds you get on usb mounting in android..not through recovery..Its frustrating to have USB writes less than an MB/s and have a class 10 card..
yeah that speed is very slow, no matter how good the card is, so i never use that way to transfer files i always take my SD out and put it into a card reader.
I actually tried pershoot's kernel right after the first post and then found it to be extremely good at USB transfers..even idling current is at an all time low..iR's and Redstar's used to give me about 105-115 mA on idle and screen on but pershoot's is giving 80-90!! and ROCK STABLE too!! no hiccups or jerky scrolling on any screen.. hell of an improvement..
may i ask if there is any difference in performance if the app partition is set as ext2, ext3, or ext4?
Thanks for the post. It got me going in the right direction.
32k clusters have mostly corrected the crashing and locking up my phone was doing with a new Wintec 32GB Class 10 card.
strangely If I create a file system in linux with
mkfs.vfat -s 32 -S 512 -n "Sdcard" /dev/sdc1 it results in 16k clusters..
mkfs.vfat -s 32 -S 1024 results in 32k clusters but windows XP can not access this file system and asks me to format
mkfs.vfat /dev/sdc1 results in 16k clusters
I had to use fat32format.exe on a windows machine to get 32k clusters with 512 bytes per logical sector that work both in Windows and Linux
so my question is how would I use mkfs.vfart to make a file system with 32k clusters that windows can read as well?
edit: my opinion on the ext question is that ext2 has a leg up on speed because it does not journal data and spends less time writing. however most people care about the integrity of there data and fsck is a terrible use of battery.. it seems the best of both worlds is ext4 with the mount options noatime,nodiratime,barrier=1,data=ordered as most roms now use

I'm so glad i came across your post, I have the same sdcard as yours and had exact same issues as you had post. I was starting to believe my phone is faulty until reading your post pin pointed to the problem.
So i Formatted with 64KB allocation size, 27GB FAT32, 2.5GB Ext4 and 500MB Swap. I can already tell the phone is snappier, gone the reboots , app freezes ..etc.
UPDATE:
So i jumped the gun. Having not done anything about the voltage table i'm seeing the Freezes/Reboots time and time again. @houzuoguo Where can i find a voltage table that will work with my SGS II KE7 CF-Root?

do you know... idle current should normally be below 20mAh, otherwise it means that your phone doesn't "sleep", something prevents it from sleeping... nightmares probably.
my phone uses about 4-9 mAh when idle.

i've read a lot of posts, people don't recommend using ext4 for flash storage since ext4 read/write more while enhance file system integrity, however i have not read anyone who says ext 4 runs slower.
these file systems are very much compatible with each other so basically i can say that their performance is very close.

I in fact have noticed that lowering voltage still works fine with the card, however previously i could lower voltage by 100mV, now i can only lower it by 75mV, and the card still runs stable.
i don't have a SGS2 (i really want one ) so i'm afraid that i don't know much about android development of the phone.
Voltage table is built into kernel, some kernels support you to modify voltage table, while some others do not. First you need to make sure that the kernel you're using supports customizable voltage-table. then i suggest you to look into your phone's kernel's code, find out the default voltage table, and make changes accordingly.
I've got the same card. I haven't noticed any bad issues. Phone is noticeably faster than with a class 4.

I am using Lexar 16GB Class 6 MicroSHDC. Transfer rate from PC by USB cable was ~ 1Mbyte/sec. Some days ago I installed CyanogenMod-7.1 for Nexus One and transfer rate dropped to ~700 Kbyte/sec. So you can try another ROM.
Well I just bought an ADATA 32GB class 10 and I’m having issues. It’s formatted fat32 w/the 32kb (did try 64kb) cluster, but any time I move data into the EXT3 or EXT4 partition that’s when the issues come up. I can use my ADATA 16GB class 10 without any problems. My ADATA 32GB class 4 just went bad, so that’s RMA. There were never any issues with that card. I did have a Patriot 32GB class 10 for a while, but lost it & that one never worked out either. If anyone has any other ideas I should try before I return this card, I'll try it.
UPDATE: Official response from ADATA “ split partitions are not guaranteed, EXT as a secondary partition is very complicated..”

anyone have try this one maybe? I am thinking of getting this one but have not gotten any review from here.
any help would be appreciated.
Class 10 sd cards are no good for smart phones so you'll always get sub par results. Class 6 is the highest you should go for best results

64kb cluster size?
What tool are you using to adjust the cluster size to 64kb? I've got a couple SD card formatting utilities but I don't see that option anywhere, and they seem to default to 32kb.
Thanks
I understand that hard drive sizes are somewhat less than advertised, but 25% seems excessive. Mine is reporting as only 11.66GB instead of 16GB. Is that the same for others of you?
Thanks, JCHP

I'd be willing to guarantee, the reason it reports as 11.66GB is because the remaining internal memory is being used for android itself and of course, touchwiz.
My Note reports something similar, as I believe the last time I looked at my applications manager, it showed about 9-ish GB free with 2-ish used. That's about 11 and some change in total.
There's 16GB total storage. kernel, recovery, system, cache all take chunks from that.

Hi!
I wanted to try nativeSD for my HD2, and have tired to partition the card.
As a result the card can't be partitioned/formatted correctly any more.
What I did:
Started with a regular fat32 formatted and working Sandisk Ultra-1 32gb microSD card.
Booted Ubuntu 10 (and 12 later on) in VMware (connected the usb card reader to the VM), tried partitioning with gparted and the built in disk utility.
After applying the new partition layout (4gb EXT4, 25gb FAT32) gparted and disk utility both stalled.
I tried multiple times, even tried to go back to just one FAT32 partition, no luck.
Then I turned to windows tools Easeus Partition Master and MiniTool Partition Wizard. They will erase the partitions, but just stall when creating the new one.
My Nikon d90 will happily format the card to 32gb, but I can't write any data successfully to it. Same with Windows disk management.
I tried 4EXT recovery, and I get a bit further, but it also hangs on creating one of the partitions. I can see that the new partitions in miniTools/Easeus.
What do I do? I'm sure this is a soft error, but how to get the card back in working order?
TLDR; fudged partitions, how to get a working card back?
how bout regenerate da sector bit by bit again, seems like some sector damaged leaving da sd a 'scar' to rewrite data,try using regenerate software such as hdd regenerator or others. but... it ll take some....not some, but much of ur time to wait, but maybe it worth it

Erm, it's flash memory, there can be no 'scars', at least not ones made with software. HDD regenerator is useful for physically damaged hard drives, not flash memory.
In the mean time I used linux fdisk to start from scratch, deleted all partitions, made new ones, used mkfs, etc. Similar results.
I'm trying the official SDCard.org application, it seems like it hanged but it's now reporting 7% done. Will leave it overnight.

Tried it just now and it hanged on formatting, stuck at 0%. Damn.
The official SDCard.org application did finish eventually, and it seemed all was well. I could even copy and read small files, but hanged on bigger (>1mb) ones.
I'm on the verge of giving up and returning the card, which is a hassle as I bought it from the UK.
Have I really damaged the card with partitioning?
This is the fdisk info on the card:

I beg experienced devs to give me some clues.
Is the starting sector ok?

Well that's the only sensible explanation, but I did use the card for some time in my DSLR. I put at least a few GB on it successfully.
Also it's my second UHS1 card, the first one turned to be defective from the start with the same symptoms
Weird.
Could be a bad batch of chips, or they might be knock-offs.

seems so.
I had 16+ microsd cards with no faults whatsoever. Until I wanted a class 10 card.
After this I'm afraid to partition the other cards :crying:
If it was a SanDisk class 10 card, and you bought it off the internet, then it's almost definitely a fake.
Don't be scared to make partitions. Just be aware that most partitioning software will not preserve any data, and that that writing any data to the card shortens it's lifespan. If you trust it more, you can partition your card from within the Advanced menu of your recovery (e.g., CWM).

Out of curiosity have you tried to return to amazon? They are very good about it in US, so you usually won't be charged for return shipping.

The first UHS-1 card, yes, very easy to do. This second one, which I have for more than 30 days, not so much. Can't find clear info on returns.
If there's anyone from UK reading this and has experience with Amazon returns, please chime in.

I advise that you go here : http://www.sandisk.com/about-sandisk/contact-us/
(sandisk contact us part of the website)
And contact technical support. tell them you cannot format the card and tested in several devices.
They will send you a semi-automated response, with a link to a form where you need to register the product and you can use their warranty.
There is a product code / serial field. Don't know if it's required for an sdcard.
You should be able to return the product to them, and they'll replace the card,
I have a defective card too, coming from amazon as well.
I think amazon removes the possibility to return a product after a few weeks.
I've been able to return mine to amazon.

Ha, got my RMA authorization from Sanisk, will be sending it on Monday.
Partitioned two other class 4 cards. working fine, my HD2 is finally running smooth.
Hopefully the replacement card will work.
I have the prepaid verizon 8gb one. It only has 5.52gb for the partition, and even when new it had like 1gb taken up.
If I installed CM or something would it take up less space?
you can either install a rom that uses less space or repartition and expand the userspace partition
Hi! I bought a sd card on internet, it said "64gb sd card. 8gb real bla bla bla" It was at good price so I bought it. When I had it I saw 64gb, but when I wrote data it dissapeared. So I try a few programs, like:
"mi sd (mb): 63999.96875
The media is likely to be defective.
7.4 GByte OK (15709801 sectors) 8043418112bytes-7670.80127mb-
54.9 GByte DATA LOST (115327383 sectors)
Details:7.1 GByte overwritten (14905344 sectors)
0 KByte slightly changed (< 8 bit/sector, 0 sectors)
47.8 GByte corrupted (100422039 sectors)
15 MByte aliased memory (30720 sectors)
First error at offset: 0x00000001ce6cd200
Expected: 0x00000001ce6cd200
Found: 0x0000000000000000
H2testw version 1.3
Writing speed: 8.87 MByte/s
Reading speed: 10.8 MByte/s
H2testw v1.4"
So I bet it has 7.4 GByte OK.
My question is how do I format it to its REAL capacity, I'd like to know if there's a specific program to do that, 'cause I've tried with normal programs but I always did it and experienced problems, I'd love to format it so it KEEPS ALWAYS at its real capacity. Thanks!
