I have several SD card issues that hopefully someone can help me with.
First, I have an 8gb card, but only 7.3 of it is accessable. I have a micro SD card reader, and Gparted. Re-formatted the card a couple of times, and it always comes up as 7.3gigs.
Second, when I rooted my phone, I used the Recovery image Ivanmmj has in the stock 1.5 to root thread here on this forum. Shortly after, I think when I flashed ClockworkMod Recovery, I lost the ability to get into recovery by holding volume up and power. Only volume down and power gets me into a recovery state.
Third, I went into ADB and entered some commands from other places to do stuff to the Sd card, but one command still lingers when I do backup or restores:
E:can't mount /dev/block/mmcblk0p2 No such device.
Either that command is blocking off a section of my SD card, or the card just has a bad sector... Any ideas guys?

was gonna say card has bad sector, or clockworkmod has a signiture for that file space like a partition, I have read that clockworkmod does this to phones, this is one reason why they brick, and we are told not to use clockwork for this very reason. there are some very nice features in clockwork mod, but for recovery its best to stay with amonra and use the update.zip to change to clockwork if you need to i have included the update.zip
I have never seen an 8gb card with 8gb accessable. It doesn't sound like anything is wrong here as far as the capacity of your card. My 8gb card has only 7.3 accessable as well. It is standard for any storage medium wether it be an sd card or computer hard drive.
As far as the volume up issue, it has always been volume - for both my phone and my girlfriend's phone. I used the Eris Root For Dummies method for my phone and the One Click Universal Root Method for my girlfriend's. Volume + and end never worked for either phone. Don't know why, but I can get there reguardless.
Hope this helps some.

There is nothing wrong with your SD card.
Hard drive, SD card, and USB thumbdrive manufacturers typically define megabytes, gigabytes, etc as incrementing by powers of 1000. (so 1GB = 1000MB)
Most operating systems & software define megabytes, gigabytes, etc as incrementing by powers of 1024. (so 1GB = 1024MB)
So according to the manufacturer, your SD card has a capacity of 8GB (8000MB)
According to any operating system (Android, Windows, OSX, Linux, etc), your card has a capacity of 7.8GB (8000MB / 1024)
When you format ANY storage medium (hard drive, SD card, etc), the stated capacity of the device and the available capacity will not be the same.
To make matters worse, some of that 8GB/7.8GB (depending on how you measure) has to be used by the file system to figure out exactly where all of your files are being stored on the card.
I don't know if you ever had to use a card catalog system in a library, but think of it this way.
Let's say you build a library capable of holding a thousand books. However, you're not going to arrange the books according to author's names, titles, or the Dewey Decimal System. You're just going to stick them on shelves in whatever order you get them in.
Whenever you need to find a particular book, you're going to need some way of figuring out exactly where it is in the library. So you'd need a card catalog of sorts. This card catalog is going to take up some of the room in your library, meaning you won't be able to store EXACTLY 1000 books anymore.
Okay, it might not be the best analogy in the world, but it's late here and I hope it gets the point across.
From wikipedia: "A general rule of thumb to quickly convert the manufacturer's hard disk capacity to the standard Microsoft Windows formatted capacity is 0.93*capacity of HDD from manufacturer for HDDs less than a terabyte."
So out of that 7.8GB of space, you're only going to be able to use about 7.3GB of it (7.8 * 0.93).
Oh, and as for
"E:can't mount /dev/block/mmcblk0p2 No such device. "
I'm not too certain about this, but i believe /dev/block/mmcblk0p2 is the mounting point for apps2sd partitions, assuming the ROM supports them, and if you're running a stock ROM, it won't.
Your recovery image does though, so every time you do a nandroid backup/restore, it checks for an existing partition for apps2sd. Since it doesn't exist, it shows that message. Nothing to worry about.
Hopefully someone who knows a bit more about it can explain it better, but I don't believe that's an actual error in this case.
I do know it doesn't have anything to do with your 8GB/7.3GB issue though.
Did you try partitioning it on your phone to 0? That worked when I had a similar problem.

*I've spent a lot of time searching...all the answers I come up with involve copy and paste the folders...which is what I did...but windows doesn't show me my ext3 partition.*
I recently rooted my G1, formatted my 2 gig SD with a 32mb swap and 500mb ext3 and flashed cyanogen 4.0.1. I quickly realized that a 2 gig card was just not enough (now that I'm left with 1.1 gig...) so I purchased a class 6, 8 gig card
I plugged the phone in to my computer, copied all my files, put cyanogen recovery 1.4 on the 8 gig and booted to console, formatted the card to my 7200, 500 and 32mb partitions. Shut the phone down, stuck the card in my card reader and moved all the files that were on the 2 gig onto the 8 gig. Booted the phone...damn it...no apps!
Took a few minutes of head scratching before I remembered that cyanogen 4.0.1 does the apps to the ext3 partition! all my apps are on the 2 gig! *arg*
Is there a way to clone the 2 gig card to the 8 gig without messing up the partitions? or just copy everything from my ext3 to the new ext3?? I really don't want to go through and download all the apps I had again
I found some SD card clone software (sprite? IIRC) but that looks like its specifically for WM devices.
As I understand your SD are formatted to ext3. Best solution is download any live linux distribution (live = run from cd into ram without installing and changing anything) and copy files normally.
yeah all ubuntu iso's include a live os you can boot up in without it installing anything to your harddisk there you should be able to read ext3
Hadn't considered that...
Thanks for the help
unfortunately, even just sticking the 2gig card back in the phone none of the apps work the phone boots and I get a long list of "xxxxx encountered an error and must force close"
looks like its off to the market for me...
*sigh*

Just for future reference....how does one go about backing up the ext partition of the SD card so if your current card has an issue you can stick the backup card in and keep running without having to download all your apps again??? I mean...if removing the original card, then turning the phone on with a new card in there caused it to "forget" the location of all the apps when the original card was installed...how does a backup card do you any good??

This thread appears to be the answer...If I ever have to get another card, I'll give this a try.
I use HDD Raw Copy, just use a partition manager to resize old partitions
http://hddguru.com/software/HDD-Raw-Copy-Tool/
Greetings
I've used GParted from Live USB Linux (I use PuppyLinux, but any other Live Linux with GParted would do) to copy partitions between sdcards / usb drives / hard disks. It's GUI based, very simple and does the job.
Just plug both the sdcards into your computer before opening GParted,
Once open, GParted would ask option to use only one device or all devices - make sure you select all devices.
After it loads all the devices, you can select the 2GB card, right click each partition, copy and select 8GB card and paste the partition there.
Please follow the partition order so that you don't change the order in the 8GB card.
Once all the partitions are done, you can resize the partition you want to make bigger on the 8GB to fill the card.
After configuring everything, click Apply and wait for GParted to do all the magic!
Hi,
for a few days im not able to write anything to my sdcard (SanDisk 8GB). Im sure its not permission related (read only mode..). My computer (linux) can read flawlessly, just like my phone (Moto Milestone/TheFroyoMod 2.4c). But when i copy files to the sdcard and plug it back in, the new written data is lost. Same for my phone. I can take photos but the files cant be stored on the sdcard. I already tried to format the sdcard with GParted but it wont let me do ANY changes. Even if i format it to another FS, when i plug it back in, its still FAT 32 with all the data still on it. Windows wont let me format it at all.
Does anyone have a similar issue and manged to solve it?
ty!
Is it an old card, been used a lot? It may not be the case, but it sounds like nand that has run out of write cycles.
well ive been using it for 6 months now. Just regular usage.
It sounds like you've tried everything available to you. I'd recommend copying the contents of the SD card onto your PC for safe keeping and try to source another card.
A week or so ago, I flashed this ROM onto my phone. ([ROM] (v1.2.6_r2) Nexus AOSP Gingerbread 2.3.4 - Faux123 [Jun-26-2011] - http://forum.xda-developers.com/showthread.php?t=1068367&page=189)
I had to end up switching back to stock ROM. Ever since the flash back to stock, my memory card has been "locked"
In the process of flashing my phone back to stock, my external Micro SD card became locked to "Read Only". I cannot format or erase any of the content that was stored on my card during the flashings. It literally seems to be "LOCKED" onto the card.
I've tried the windows format option in the Device Manager. I've also tried the Windows Command prompts. NOTHING has worked. Formatting the card in my phone does nothing. No data gets erased.
With the card in my phone, I can access all my files (movies, music, pics, etc). But I cannot modify, delete, or add any new content! (Example, I cannot select my External SD as a valid storage location for new pics in the camera.)
Does anyone have any ideas on how to reformat this card to get it working for me again. It is a 16gig card. I hate to throw it out.
Thanks.
I would recommend trying Panasonic's sdcard formatter. It seems to be pretty good at formatting sdcards that other programs have trouble with.

Another thing you could try, you can format your sdcard inside clockwork recovery mod. (Under the mounts and storage section if my memory serves)

Thank you for the suggestions
That did not work. I ran the SD formatter and the windows formatter and my content is STILL on the card.
CWM won't format the card either.
Any other ideas?
Did you try partitioning the card? Just one 16GiB FAT32 partition?

Joe -
That is officially over my head.
How would I go about doing that?
Can you get the card replaced under warranty?
Since you tried formatting the sd card, I am assuming you have backed up everything on it.
As easy way is in Clockwork recovery mod choose -> advanced; then choose -> partition;
when prompted for a partition size for the ext partition choose the smallest, also the smallest for swap (I think you can choose 0 for this one) continue to follow prompts and the card will be partitioned.
One more thing to try if that doesn't work:
http://gparted.sourceforge.net/livecd.php
Go to this site, download the cd or usb disk version and boot off it. Now, plug your card into your computer (NOT through the phone, use a usb reader. If you don't have one, you can probably pick up a cheap one for around 10 bucks.), you may need to rescan the disks after you plug the card in, to make sure gparted sees it. Now, delete the entire partition, so there is no partition at all on the card.
Boot back into windows, plug the card in, try to format it again. I've seen this happen when you have a damaged mbr on the sdcard. Also, when you format in windows, (if your system will allow it), id try to format it to a 64k cluster size instead of 32k. (on a 16gb card 32k is the default cluster size.) It'll speed it up a bit. (not really needed, but a nice boost.)
The last thing you can try, if all else fails, boot into clockwork recovery (assuming you have it installed) and format the sdcard through there.
If all that fails, I'd say you have a bad card. But try those steps first, hate to see you throw the card away if it's still good. )
Big problem. I have a Lexar 32gb sd card and today it seems to have went corrupt.
I noticed it when my ring tone change from a song to default. if i put the sd card in my PC and try to read from it it says card needs to be formated. Please tell me there is a way to recover the info on the card??? when i put the sd in the phone it says preparing then says safe to remove sd card.
TIA
JC
Hopefully just a format is all you need. I lost a 32g USB drive recently, and fortunately Corsair has great warranty service.
Sent from my Bricked Energy Sensation.
My wife's sensation did the same thing, I had to take out the SD and put it into my SD card reader on my laptop, format it and then put it back in the phone. The phone then wanted to format it again which it did and now it seems fine.
By the way, the data was intact when I put it in my SDcard reader. I was able to back up the data before I formatted it.
He said he wanted to recover the files on the SD card, not how to get the **** thing working.
You might want to check if all of the connections are clean. If they're not, a format the ****-error is likely to happen. Pure alcohol might do the trick.
If it doesn't, you could search Google or the forums for terms like 'recover corrupted micro SD'.
Good luck!
Edit: Maybe this guide does the trick?
I've an other question. I made the mistake to format my SD card with CWM and now it's only a 4 GB card (it should be 8 GB). Does someone know how I can force format it to 8 GB (with Windows or Mac OS disk utility, I can't expand the size anymore, just reformat it) ?
you can use sdformatter, a great and simple tool for those types of things, or you can download easus partition manager, its free and pretty good software for drive management.
If you want to make a linux disc, such as Ubuntu, gparted is one of the best tools available for examining, repartitioning, flagging, and fixing disks. I believe you can just download gparted and boot it from a CD or flashdrive, but I think just downloading a linux distribution is easier.
My SD was acting a fool (after deleting many ROMs, it still said I had 73MB free). Nothing I did would change it so I decided to format the card. I used Disk Utility (on Mac) and formatted for FAT32. After I did that, my phone said it was in a format it couldn't recognize, so I formatted it from the phone itself. Now, when I enter recovery and attempt to install zip from sdcard, then choose zip from sdcard, it says "E:Can't mount /sdcard". I don't really know what to do, as I formatted it from my phone. I figured that was sure fire but I guess not so much. I tried to find what format I need the SD card in to work properly but I couldn't find anything.
Can someone help me out?
Fat32 is correct for the phone. Do you have a usb reader for the sdhc microsdcard or one of those sdcards that let the microsd card fit in to read it from the pc?

Reboot in recovery, if it says it can't mount it... pop out the sd from your phone and pop it right back in and see if it works. No need to mess with mount points for it either.
Also, did you check if your lost.dir folder is taking up space? Sometimes that thing can get big.
Could have been a bad flash, try to flash it again. I know I had a problem when I bought a new sd card. You can also try to flash it from a different phone. Otherwise, if you have access to a pc, I can tell you how to format it from the command line, which is, in my opinion, better to do if you're having a problem with the quick format that the phone does.

Sounds like what i did one day when i wanted to wipe everything so i did including formatting my SD card through recovery. so it left me with nothing on my phone including a bootable rom! lol. if this is the case with you. Here is what i had to do. Download a new rom to my PC then plug my phone into my PC via USB/ Boot into recovery/ Mount storage/ Mount SD card/ Copy the Rom to SD card then Flash the Rom. Not too sure if this helps, I hope it does, again it sounds like the same problem i had.
Sometimes SD cards break...for some reason they will just stop working, probably due to manufacturing techniques. My old 256mb card went bad, I just tossed it yesterday as a matter of fact. it had no name brand. I still have a 4gb pny that works perfectly and a SanDisk 32gb which also works great. If you do have to get a new SD card, I would recommend getting the highest class you can afford highest out the right now I believe is C10. That will increase your transfer speeds....both of my current cards are class4 and it can take a little bit of time to transfer gigs of data between the phone and computer. If you have any other device that can accept the "card" put it in there and check if it can send and receive data/ format to proper disk size, if not then your card is broken.
Once you go class 10 you don't look back lol
