[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.

[Q] sdcard wont mount

Thought I would ask first... my SD card will not mount on my phone. Data seems to still be there but I have a notification saying "sdcard is blank or has unsupported filesystem." Tried to format but the card wont mount on the device. I've tried formatting in the android os and in recovery with errors. Does this mean the SD card is toast? Any help is appreciated. I'd hate to lose all of the data. Thanks.

At work right now and our computers are on lockdown, no external devices can be read. If I can access what should I do? When I tried repartitioning in recovery it said it could not mount dev/block/mm? ?? Or something like that, basically gave me an error. Any advice? Im about to just buy a new card.

You might just need to reformat the card. Sometimes the cards get corrupted. You might even still be able to access and backup the content on the card if a PC will read it. If you have WIndows 7, it might even offer to repair errors on the card. That could also get it working. I'd say reformatting it is a good idea either way.

i just had similar error... try removing and reinserting card. if that doesnt do it reboot into recovery and depending on the recovery you are using go in to mounts and try selecting "mount sd card" that last one fixed my issue.

I ended up just buying a replacement 8GB class 10 card (wanted a higher class card anyways, this gave me an excuse to buy one ). I was able to retrieve the contents of the SD card by mounting it in my computer (vista 32). I didn't try reloading it into my Evo cause now I don't have a need for it. Thanks for the responses though, glad that you guys are here and willing to help. :thumbup::thumbup:
Sent from my Modded Evo... It's easier this way.

error mounting Sd card
This is very strange and have tried but do not quite understand adk tools
The first issues is that the SD card wont mount:
Sometimes in recovery i can access the card and other times I cant;
I have tried to format it in windows, but doesnt allow me to.
I have tried using the tools on recovery to fix it, but hasnt fixed it.
The second issue is that when I try to reboot it says usb brick and fix it before i can reboot,
but this has not fixed the card.
can somebody please help me with this issue as I do not want to purchase another card.

Can you at least read your sd card, preferably in a card reader to remove any phone element? If so back up the whole card to PC
Then I suggest a complete reformat of the sdcard using gparted live cd: a single FAT32 (on the left) and then maximum 2GB ext4 partition. Again do this in a card reader to remove any phone or driver issues.
Copy contents back to sdcard afterwards.
If none of this works then you may simply have a bad corrupted sdcard. Although it's not a great solution to buy a new one, make sure you stick to a reputable brand, even those are not that expensive nowadays.

No .. I have tried several times, but pc can not read it.
I do have the contents copied though.
any suggestions, as pc can not read card.

The card is Sandisk.
I can sometimes access the card on the pc using the usb, but not all the time

Well at least you have the data backed up, so nothing to lose except an sdcard.
- Are you using a card reader?
- Have you tried gparted and a card reader? This has the best chance of working.
If you can't read or see the card by any means, then not much else to suggest but a new card.

Can see it sometimes using usb connected to phone.
will try your suggestion shortly and let you know

phone say safe to remove sd card.

[Q] big trouble, cannot mount Ext_MicroSD (M8)

Dear friends:
I don't know what happend, but I cant mount my EXT_MICROSD Card... I flashed the phone, I format the MicroSD Card, I read a lot of threads from here, but nothing, without solution...
well... the first thing was when I flashed TWRP latest recovery (2.8.1, any else) then, microSD card stop to work. I read this treathd (the problem it's the same, but with other smartphone) http://forum.xda-developers.com/showthread.php?t=691639 I tried to make all steps, but doesn't work
I set my microSD Card into my card reader on PC and I can use it.
When I get into recovery I can't "read or mount" storage microSD or USB storage"
I'm desesperated right now... :s I don't know what it's the problem!! please help me, give me a chance to repair my error... ;__;
PD. I flash full stock ROM and I tried flashing custom ROM, well... I hace this problem 1 week ago.
NEWS: I flash GPE ROM, I changed MID at least USB Storage WORKED!... but isn't MicroSDCard and the "yellow/white" flash in bootanimation it's gone

Its not clear how you re-formatted the SD. But folks have had differing results whether they use the phone's format function, or otherwise. 3rd party formatting apps on a computer seem to work better. So give that a try.
Did you try another SD (borrow from a friend if you don't have one)? Its possible the card has just gone bad.

Hi, thanks for answer. I tried using other SD Card (in the mobile), but doen't work. I put the SD Card into a SD Card reader (in the computer) and work correctly. In that moment I formatted into Fat32, NTFS, ExFat and work fine in the PC, but doesn't work in the phone.

I recently had similar issue.. either the rom could read the sd card, but not recovery or vice versa (I use Philz).
I reformatted in Philz with default settings and now it works in both rom and recovery...
Think it has to do with allocation unit size. I can't help you with "correct" setting, but I know if you have too big or too small, it can slow down read/write speeds.
What happend when u plug in sdcard in your unit? Does it say it needs to be formatted?
I found some good read about formatting sd card here

When I plug into the phone doesn't work. (now I have TWRP recovery, do you think that Phil it's better than TWRP? maybe I could try flashing that) and... the first time doen't say to make a format. but, yesterday, when I install GPE, say that. when I push format... doesn't happen.

Im not qualified to tell if TWRP is better or not, but Philz is the one I use and it fixed my SD card issue. Just give it a try... you can always flash back to TWRP after if you want

Hi have exactly the same problem? i bought my at&t htc one m8 unlocked but couldn t ever even mount external sd card, they work well outside the phone but don t function inside it, not even recognize an ext sd card.....please someone could give some help to me?

If you try formatting an SDCard on a PC, set the block size to 512 bytes.
Are the SDCard's branded or cheaper end of market?
There was (maybe still is) a problem with SDCard's of a certain version (v10 I think) and this could be a similar thing.
Sent from my HTC One_M8 using XDA Free mobile app

Well, my final score: the SD Card was loose and disconnected inside, a cell technician repair it.
