Android on sd can't access through USB! - HD2 Android Q&A, Help & Troubleshooting and Genera

Hi all thanks for any previous help I now have android on my sd. I have a small problem when I connect to usb lead that my phone shows as a drive but is greyed out can't access it? any ideas.

it's ok I sorted it.

How did you fix your problem as I can't access my phone through USB either.

Have the same problem.
Apparently the drive letter in Windows is attached to Ext2 partition and not FAT32.
I can't change the letters in Windows and can't activate FAT32 partition.
Any ideas?

It's interesting to see that I'm not the only one who's got the same problem.
@dindia2 How did you know that the partition that it was attached to was FAT32 and not EXT2 (I take it that's the main internal partition that you're referring to?)

That's exactly the problem - in Windows EXT2 was attached - i figured that out when I tried to format it - it was only 1.5GB - the size of EXT2
I eventually used xRecovery to format it to 2GB ext2, 54MB swap and the rest of 32GB for fat 32
Sorry for delay, Danny

So I take it the only way to fix this problem is to format the phone itself? If so, that sucks!

How to format the Mini SD card

Hi guys
My 2GB Mini SD card is not working. I have a Trinity - Orange SPV M700, I wonder if anyone could tell me how to I fromat it and which FAT system to use?
Sorry if this is a stupid question, but I did try to use File explorer and looked everywhere in the Settings section.
I am thinking, maybe I need to use my card reader in the computer or do I have to buy a 3rd party program to do this?
Any idea
Thanks
Using the cardreader in your computer is fine. Use the FAT format, not FAT32.

Why not FAT32? I've been using a 4gb miniSD fromatted in FAT32 for months without a problem.
If You don't have a card reader or an adaptor for the Micro-SD You can do it via wm5 storage. FAT32 should be better than FAT.
I also had problem with SD card (2Gb). Then I used one program for formating Panasonic SDformatter an now I don't have problems anymore.
Link: http://panasonic.jp/support/global/cs/sd/download/sd_formatter.html
Try with this program.

As you may know, the SD specifications are not open but must be licensed and are protected by NDA's. Therefore I pesonally can't say for sure whether or not FAT32 is within the SDA 1.0/1.1 standard, but I would guess that it's not.
It's true that using FAT32 seems to work with most cards and controllers in the PPC world, but apart from eliminating the 512 files limit, I don't really see any advantage over FAT.
FAT32 is not a 'high performance' filesystem, so in terms of read/write speed it doesn't give you anything compared to FAT.
If you use a 4GB non compliant card, then of course you must use FAT32, since FAT only allows for 2GB.
So in short, unless you can't live with the 512 limit, I don't see that FAT32 will give you anything over FAT, and when you use FAT, you are sure to be within the standard.

Thanx for nice info, if that's true, FAT32 is the only option user may have when formating card, this limit is a way to small !

Please note that 512 is not the limit of the total number of files that can be stored on the card, it is the max. number of entries in the root directory.
The max. number of files that can be stored on a FAT filesystem is 65517.
thank you for clarification, is there a way I can already check in what format my card is formated?

If it hasn't been reformatted since it left the factory, then I think it's safe to assume that it's FAT formatted.
If you want to check, then put it in a card reader and look at its properties (assuming your PC is running Windows).
i'm using Windows XP, but in my computer my pda is listed as a windows mobile phone and if right click the storage card, there's no option to format it...what should i do ?
thanks

microsd issue

hey people
ive run into a bit of a problem i removed my 8gb microsd card from my htc magic and formatted it to fat32 and also have created a fat 32 partition on it named EXT2, now heres where the issue arrises i place it back into the phone and swicth it on plug it into the usb on my vista laptop and mount the card through the phones options but it doesnt show up in the windows explorer so i can transfer anything to it? however if i put it in an adaptor and run windows explorer it sees it no probs, any ideas how to get the remount working!!!!
also does the scond partition need to be fat32 also or ? and ive called it EXT2 in caps not ext2 in lower case will this be an issue

Your problem here is you don't understand the difference between FAT32 and EXT2 file systems. Google is your friend...do some reading. Your Windows won't be able to read an EXT2 partition without some specialist software. A Linux PC will be able to read both.
Creating a FAT32 partition and naming EXT2 is not an EXT2 partition. I'd suggest you download a Linux Live CD e.g. Ubuntu and run Gparted to create a EXT2 partition on your SD Card.
The Android runs using a Linux Kernel and natively supports EXT2.

Partitions in wm?

Hello everybody,
Does wm support partitions?
So can I split up my 8 gb sd card into two partitions of 4?
Or does wm not support this?
Thanks!
Hope you don't mind me asking, but what for ?
E.g.
Partition one:
Haret > Android
Partition two:
Multimedia stuff + wm
or
Partiton one:
Multimedia
Partition 2
Program files and stuff
There is no need as both Andriod and WM6.x can see Fat/Fat32, which I presume your SD card is formatted.
If you want to separate your media from any programs you want to install on the sd card just use a different folder.
Plugging your SD card into you TP2 is the same as plugging it into your desktop / laptop whatever the OS.
Would you partition a SD card that was plugged into your desktop ?
If you want to partition the SD, try it and let us know... however i think that it will appear as 2 storage cards in explorer.
I will give it a try
It is possible but not usable...
I also searched around on the internet and it works
But I am back at one sd card since I find folders easier than 2 storage cards.

I know exactly where you're comin' from, man. After I get a 16GB class 6 microSDHC, I intend to partition ~8.5GB as NTFS ('cause I'd like the the max capacity to hold a full DVD DL disk) to handle larger file transfers btwn desk/laptops. And, I'd still have a whoppin' ~7.5GB to be used by the tele as FAT32...'just haven't made that microSDHC purchase yet, but I'd imagine it to be plausible.

I remember some time ago on Aximsite or another older related site reading how to format NTFS and use a Compact Flash card on Windows Mobile. I did it on my Axim and Ipaq at the time, and kind of remember it working.

I know. However, if there're two partitions, NTFS @ ~8.5GB and FAT32 @ ~7.5GB, then I'd imagine that Windows would see the storage card as two drives, while Windows Mobile would see the 16GB, storage card as ~7.5GB. Anyone, please, do correct me if I'm wrong in my assumption.
This has made me wonder, too. Why does WM refer to "Storage Card 1" occasionally when inserting/unplugging memory cards...? It kinda implies that there is room for multiple cards at the same time...????
Chris
i partitioned my 16 gig hard drive and installed linksys on one partition so i can plug into my computer and dual boot from my phone...
i dont really see a reason to create multiple partitions to have the same function as folders (ie seperating media from doc, ext...)

You would not gain anything by formatting NTFS other than the ability to set NTFS permissions in Windows. A movie can be stored on a FAT/FAT32 partition with no ill affect on usability. Also, when you purchase any type of storage, the actual formatted size is usually smaller than the advertised size. So if you buy a 16GB card, you will most likely end up with around 15GB max of usable space. I would not plan on having 7.5GB of free space after creating a 8.5GB partition.

No, you'd also be able to support files larger than 2GB. And, I know it wouldn't be 7.5GB, that's why I'd said about (~). Prob more like 6.8GB, or so.

I know NTFS doesn't work on Windows Mobile. However, I would assume that if you were to make two partitions, one NTFS, and the other FAT32, the Windows Mobile device would show the FAT32 partition, while a Windows dsktp would show the microSDHC as two partitions, NTFS and FAT32. I've ordered a 16GB microSDHC Class 6, and I'll post my results after I receive, partition and format the card.
Okay. So've received my 16GB microSDHC Class 6, and have partitioned and formatted with Paragon Partition Manager Pro v9.0, and have...
Partition 1 - microSDHC N, 8.61GB NTFS
Partition 2 - microSDHC, 6.24GB FAT32
The device sees the FAT32 partition, as intended. Windows (Vista), however, shows only the 1st partition (NTFS) of the microSD, even when using the device in Disk Drive USB mode. Disk Management sees the FAT32 partition, but no matter what options I select, I'm met with
Code:
An unexpected error has occurred. Check the System Event Log for more information on the error...
At this point, I just need Windows to allow me to give the partition a drive letter. Any help would be greatly appreciated.
in the start search bar type computer managment then go to storage/disk management select the disk and then right click and change letter.
thats supposed to let you change the letter i have to deal with this alot at work with all the network drives and my externals
hope this helps

Partitioning SD card

Hi,
I recently got myself a 16-gig micro-sd card on which I want 3 partitions:
1) 12gb (FAT32): Media
2) 2gb (ext2): Apps2SD
3) 2gb (ext2): Debian
I've been trying to make them with gparted and I can't create 2 ext partitions. Whenever I try to format 3, then 2 gets corrupted. Then I fomat 2 again and 3 gets corrupted.
Everything works OK with just 1 FAT and 1 ext partition. The problem comes when I create the two ext partitions.
Does anyone have an idea about what the issue is?
Thanks in advance.
No one? Has anybody managed to create a similar layout on their sd card? Anyone with two ext partitions?
I'd appreciate some info.
Is there a reason for ext2?
Have you tried ext3 / ext 4? Even if you don't want 3 or 4, might be good to try for troubleshooting purposes.
Any reason for two ext2 partitions?
If no one here knows, a great place guaranteed to have the answer is http://ubuntuforums.org
2gig for applications is WAY overkill, even 1gig is. Just use a ubuntu live cd, if you don't run it already, to format the card.
ext3 supports journalling, which I think may be harmfull to my sd card.
I don't really think the 2 gigs are the issue here. Any size will fail. I'll try a few more things tomorrow and post back.
Thanks for the replies.
BTW I do use Ubuntu as my main OS.

[Q] Problems to get my ext partition seen...

Hi all,
One question:
Can it be, that with some SD-cards the creation of an ext partition is not possible?
I've got a sandisc 32GB card in my HTC HD2.
I formatted it in an external reader under XP using 'card formatter' in fat32.
Then I used partition manager to create one big fat32 partition, cluster size 4096 an a small, 1GB ext4 partition, same cluster size. Both are set to primary, first is fat, second is ext.
It doesn't matter, if I choose ext2, 3 or 4, as soon as I insert the card in my phone, the ext partition is not seen by it...
Using Titanium Backup, the ext partition should show up...
Under XP, in partition manager, everything works out smooth and both partitions show up fine.
Thank you for your suggestions!

what do you mean when you say ext partition is not seen by phone?
When you open titanium backup, in the lower part of the window, it shows:
System-ROM: 'size(free)'
Intern: 'size(free)'
SD-card: 'size(free)'
and then there should be ext?: 'size(free)'
but it doesn't show up...

Format the SD-card using CWR (P.s. everything gets deleted on the SD-card)
in CWR, the card gets formattedd, but no ext partition comes up
I tried several times, but checking in my cardreader, there is no ext partition
I read and tried already so many tutorials and howtos from xda and other forums, that for now, I'm a bit confused...
Some of them say, the ext partition has to be the first, and others say, it has to be the second...
But all point out, both have to be primary and clustersize should be 4k...
So I start to think, maybe its because the card is too big?
All reports refer to cards smaller than 32GB...
what rom are you using ?
[OCT16] AmeriCanAndroid AOSP HD2 GB2.3.7 CM7 | bk2sdext [KERNEL:ACA823]
thats an SD build isnt it? i dont think the ext partition works on sd builds but i could be wrong
an ext partitoin is used on nand builds, what exactly are you needing the ext partion for?
no, its a NAND-build, runs on clk...
I was running it from SD for over half a year and switched to NAND-version mid september...
From that time on I tried to get the ext stuff running, by reading and trying, but now I decided to ask
Weird.. I stick my SD-card in a computer and remove all partitions leaving it blank. Then CWR-partition it. Has worked for me all the time..
Can you try with a smaller card??
For me its weird too, I briefly followed every tutorial I've seen so far, moving the ext partition from the beginning to the end, trying different cluster sizes...
Thats why I ask if it might be the size of the card, everything else is working fine.
I've got a 2GB card lying around somewhere I'll try to find it and see if that one works.
One thing, thats making it a pain in the a.. to try again and again is, that in the meantime I've got about 16GB of music on my card, which is taking some time to copy everything back
Ok, just to end this:
I managed, to get it to work.
I didn't change anything in my setup, but after downloading Link2SD from the market, my ext4 partition is recognised and working
It's still not recognised by TB or other skripts, but thats ok for me, as long as I can use it...
