[Help needed!] Cant' mount sd card - dev/block/

Hey guys, today morning i got a problem with my desire. the screen was black and there was no possibility to turn it on.
I restarted my desire and got stuck in boot loop.
So I wanted to restore my backup but everytime the recovery tries to mount the sd card it says "E:can't mount /dev/block/mmcblk0p1"
and "E:can't find /sdcard/update.zip"
I also tried to mount my sdcard with a cardreader but neither windows 7 nor XP recognize my sd card.
So is it possible that my card is broken, if so that wouldn't be as bad as having a broken phone.
I would apreciate any help!
Thank you

I had this same problem after I tried to answer a call my phone reset and went into a boot loop, I went into recovery which seemed really slow for some reason and the phone would not see the memory card, so I removed battery and left the phone off for ten min's and then tried again and all was well again.

unfortunitely, even after half an hour without battery, it keeps on saying can't mount /dev/block
I guess my sdcard is broken, could that be?

Does it say "Invalid Argument"? If you have a linux system, try and format/overwrite the card (using dd if you can) and you'll see a "short write" error - your card is broken unfortunately. Mine did the same only this weekend

I too have the same problem, but I think mine is way worst!!
I've tried with 2 different sd cards, and I still get the "E:can't mount /dev/block/mmcblk0p1" and "E:can't find /sdcard/update.zip" error.
If anyone knows a solution...

I just bought a new sdcard...and after doing the whole rooting process again, it works fine! so my problem was probably a broken sdcard. I just wonder how that could happen...didn't touch anything.
Thank you guys
I hope for everyone who has the same problem that a new sdcard fixes the problem

I think it was just age. The one that failed a few days ago for me, was over a year old (I would have thought it should last longer than that).

I know this is an old post, but I had issues with this today and I managed to solve it, I just want to share what I've done, it may be useful for somebody.
I formatted my SD with a 1gb ext4 partition and 7gb fat 32 partition. I put everything back to the fat32 partition but my rom didn't boot up, so I tried to enter recovery and I got the can't mount sd card error.
I just deleted my partition and created a whole fat32 partition, no ext. After that I could use the update.zip with no issues. Updated my ROM, used ROM manager to create the ext partition and now everything is fine.
edit: I'm not sure, but maybe you need to label the partition as sdcard.

[Q] Can't mount SD card (no ROM installed) [SOLVED]

First: Yes I've looked at other threads my problem is slightly different and, yes it is my fault for trying stuff beyond my level of skill but I know XDA members are helpful so I'm trying my luck.
Problem: I rooted the device (HTC Desire) and was running LeeDrOiD V2.2 until I came across the new senseHD ROMs for the HTC Desire and this is where the problems started. In short, I tried to upgrade to the SenseHD ROM and in the process wiped my SD and phone memory. the device can still boot into recovery but it gets the following message when trying to access the SD;
E:Can't mount /dev/block/mmcblk0p0 (or /dev/block/mmcblk0p1)
(Invalid argument)
E:Can't mount /sdcard
The card is 2GB and reads fine on my windows machine. I've tried formatting and placing ETX3 and ETX2 partitions, I've also tried just copying all the old data that was on the SD before I started playing but the device just hangs with a black screen reading "android". The trouble is that all the solutions I have come across for similar problems are solved from "inside" the ROM either through ROM manager or by changing settings. Obviously these are not options for me.
I would like to install the senseHD ROM (RCMixHD v0.11) (or anything at this point) so please could you help to fix this and have a working phone again.
please please please help out if you can, I'll be eternally grateful for any advice.
many thanks in advance!
SOLUTION
I managed to fix it in the end. I got a hold of another SD card from a friend, put a ROM on it and booted up the phone. Made sure the phone could boot up without the borrowed SD card. Then I took the original SD card and deleted all the partitions (DID NOT FORMAT) in windows using (MiniTool Partition Wizard) placed it back in the phone and booted up using the ROM that had just been installed.
In the phone settings go to Phone and SD storage, mount the SD card (don know why it manages to mount here) and then format it.
Now the SD card is fixed!

You could try repartitioning the sdcard from recovery.
good luck.

I had the same problem. I needed to update my version of Clockwork Recovery. I used the ROM Manager to install the latest version. Now its working for me.

I'm also in the same boat and the fastboot command to re-enable the SD card didn't work for me.

PLEASE HELP...Can't get SD Card Swapped!!

I just got a 32GB Micro SD Card for my evo and I am trying to replace my current 8gb card. I was previously running MIUI 11.26 and using clockworkmod recovery. I followed these steps because I couldn't find anything Evo specific:
http://theunlockr.com/2009/10/15/ho...-android-when-using-swap-hero-and-or-apps2sd/
when trying to format and reapply the rom i was using i received this error msg:
E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0) (No such file or directory)
Now I don't know where to go from there. I previously had a 16GB card fry because apparently i didn't take the correct steps to get it working properly, i do not want that to happen again. Can ANYONE give me specific instructions for swapping my SD Card for my Evo?? If so I would GREATLY appreciate it!!!
And yes...this is probably rather "noob-ish" and I DID already search the forums for any help and couldn't find what i was looking for. Again any help is appreciated
Thanks!!

just copy all files from your 8g card to the 32g card pop it in the evn and you are good to go, nothing special required. Unless you are using apps to sd, then the easiest way s to put all apps back on the phone, then after switching to the new sd put them all back on the sd.

Yea I tried that and kept getting an error msg. I think there are specific steps for partitioning etc I just don't know them.

sorry if i'm misinformed but the evo has 2.2/apps2sd built in and 2.2 partitions the sd card on reboot. The article u linked i believe is for devices with 2.1 or ealier and a modded apps2sd . I have swapped many different cards and have not had to do anything that special.
Here are my steps:
1. go into settings manage applications and pull all apps back to phone.
2. copy all files/pics/vids/whatever u want to keep to computer.
3. power off, swap out sd cards, power back on.
4. phone should boot and partition sd or whatever.
5. use astro file manager and if it shows directory for sd, asec, secure then everything is good and u can move apps back to sd.
6. hook phone to sd and move all your kept files from old sd to new sd

I have seen your problem happen with a bad sd card, where did you get the 32g card. You may want to test it and see if it is actually a 32g.

Thanks for the response...just a question before i go forward with it, when i replace the card and reboot the phone, is it automatically going to boot up w/ the rom i was using before replacing the card?
Edit: Tried these steps and got stuck in bootloop for MIUI (rom i had flashed previously). Even tried to put the initial PC36IMG file on the sd card and flash it through recovery, nothing! It searched for it then says it directory cannot be found. I've put the 32gb card in my card reader on my computer and it comes up just fine, I can add files to it, format it etc and everything works, any other suggestions...this is becoming highly frustrating! Again any help is definitely welcomed!

So i still cannot seem to get this working, and I've tried doing a lot of different things and nothing is working for me, I have tried to install some sort of file manager program (astro) but it doesn't recognize my sd card, yet my phone shows it as mounted and with plenty of space available. I do not know what else to do...can ANYONE help me?

i had a similiar problem recently. For christmas I received a new sd card. At fist it didn't recognize my card. I tried to format it using my PC but I then went to my recovery (Amon RA) and clicked on the Partition SD card option.
After I partitioned, I turned on USB-MS toggle and put all my files back into the phone (including my rom zip).
I disabled USB-MS toggle, and then wiped data/factory reset, cache, dalvik-cache
Flashed zip from sdcard and violoa. It works!
try that one out.

Error mounting SD Card

I've decided to try a new rom today, Iceandfire v1.6. I was previously using sense ginger and just thought I'd try something new since I was bored and curious. I downloaded the rom and gapps and booted into recovery. I wiped data/format and cache aswell as dalvik. I installed from SD card the iceandfire and gapps and reboot the phone. Upon the first boot I got an error saying "Damaged SD card" and suggested I format. So I clicked yes to format but that did nothing at all and just gave me another Damaged SD Card error.
So I said, "OK then, my phone doesn't get along with this ROM, I'll just go back to sense ginger." Rebooted into recovery, started a full wipe again, only this time it gave the error "unable to mount /sdcard/ .android_secure!" and said failed to wipe. So I thought "HMMM!!!" and reboot the phone back into iceandfire rom and wanted to try mounting my card to PC to try formatting that way. I clicked mount and it has been loading since I started writing this post up until about 5 seconds ago and just went back to the previous "Turn on USB storage" screen.
Now I'm out of ideas....If I can't format or mount the SD card, what can I do??
EDIT: As it turns out, the iceandfire rom I flashed turned out to be for the Milestone. I found it in the G2 forum and thought it was for the G2! I thought milestone was part of the ROM name...So I flashed a rom that wasn't made for my phone and now I can't mount SD card. Any solution?
EDIT 2: Was able to wipe the sd card completely, to be honest, I'm not entirely sure how. I put my SD card in another android phone, got the same damaged sd card error, put the card back into my phone, wiped data, successful wipe, went to flash a previous rom, said no files found. mounted the sd card to PC, NO files at all on sd card. Downloading new rom now and will try to flash. Perhaps this thread could help somebody else who might have similar problem. Will edit again once I've tried flashing.
EDIT 3: Unsuccessful. I downloaded MIUI and flashed. It happened to be the only file on SD card after transferring. When I installed it, it just instantly installed, so...it didn't install. So I reboot and now it's gone back to the previous rom, even after wiping data. So perhaps I'm missing some core files? I have NO idea. Should I only need a rom like MIUI for it to work? I honestly don't know. Now that I've rebooted into recovery, there are two new folders on the SD card, lost.dir and Android. I'm formatting again and going to try to flash MIUI again. - It gives the error "Can't open MIUI.zip (bad)". Trying to download "Stock Gingerbread" rom. Will update.
EDIT 4: Once again, unsuccessful. Perhaps I'm overlooking something? Tried two different roms, neither will flash. Atleast I'm able to access my SD card. Does the root apply to internal memory or SD card? I could put a specific rom on my brothers SD card and flash it through there? Perhaps that'll replace the necessary files I might be missing (if that's the case). Please somebody help me. I know this is a lengthy thread, it's just I've tried to provide the most details I could.

EDIT 5: All is well. I used sd card from another phone to install a new rom. Everything is working now.

Unable to mount SD and to boot

Hy all,
First, excuse my english, I'm french.
This morning I was on call and suddently, it stopped and my phone freezes. I had to remove the battery.
But know, I'm unable to boot again.
Since I decided to remove the bootlogo, I don't know if it's right after the HTC screen or while booting (I knew it was a bad idea...)
Finally, after some tries, I've been able to access hboot and recovery. But recovery took 46 secs to boot and said "Unable to mount SD card" or something like that. I tried on my computer and the SD card can be accessed.
So, I would like to know if someone had the same issue or if someone can help.
Thx!
Infos :
DHD running CodefireX SR19 and latest radio. No other sign since the release of SR19 some weeks ago.

sounds like you need to reformat SD card on computer. But first copy 4ext folder to computer then format SD. After format SD place 4ext folder back on SD then remount SD to phone see if that helps. You may have to full wipe and reflash rom when you enter recover do to apps moved to SD will no longer be there but may show in rom and when you try to open they will force close.
