BUMP: I'm having the same problem, used gparted to repartition sdcard which allowed me to Mount USB storage. When i try to mount /sdcard card i receive
Code:
E:Can't mount /dev/block/mmcblk1p1 (or /dev/block/mmcblk1)
(Invalid argument)
Error mounting SDCARD:!

Are you using setcpu? I had same message the other day when in clockwork. I had an idea to try to set speed back to stock and unchecked set on boot, rebooted in to clockwork and all was well. Not sure if the clockspeed and and set on boot has anything to do with it, but I had a feeling that it messed with backup/restore when writing/reading a custom speed specified to boot with. Anyway it worked for me on virtuous with 7.28 radio and kings bfs 5

Had the same issue... Formatted the SD card (using the phone, under settings/sd card) and it never happened again.

to follow this up, i was experiancing similar problems
like an idiot i ejected the SD card with the power on (bad idea) and had to format it
the card worked fine under my rom (miui) but when i booted into clockwork mod v4.something
i unmounted the SD card in the phone options and formatted it, after re mounting it the phone gave me a notification that the SD card was an unsupported format
so what i did was click that notification and format the card again
i booted into recovery and it worked, i hope this helps someone in the future

Can't mount /dev/block/mmcblk error
I received a replacement Dinc from Verizon under the extended warranty. My problem is that the new phone won't backup or restore under CWM. I get a notice that "E: Can't mount /dev/block/mmcblkp1p (or mmcblk)
My old phone was rooted with the 2.3.4 version 4.06 GB stock rooted ROM. I made a nandroid backup with CWM recovery 5.0.0.6. So far all is good. The replacement phone with amoled screen came with GB 2.3.4. (unrooted and s-on.) Following the directions in Droid Forums I downgraded to 2.2, rooted using unrevoked3, turned s-off with unrevoked forever and reinstalled 2.3.4 version 4.06. All files found from links of XDA. (THANKS to all for the great instructions and files.)
But now on the new phone the nandroid backup and recovery from CWM won't work as I get the above error. II read that the sd card needs to be reformatted but when I put it back in the old phone, CWM works well without the error. Any suggestions?

I would first try to format your sdcard fat32, but dont put any of the old files back on yet. Then with the blank sdcard inserted try to run a backup and see if it works. If not try reflashing cwm thru hboot. Also make sure you have superuser and busybox installed. mmcbkk0p1 is the data partition, see if you can manually mount it thru recovery in the mounts and storage menu.

Its mmcblk1p1 he said. That isn't the data partition . I think it is sdcard. I think an sdcard format will do the trick.

[Q] SD Card Problems With Clockwork Recovery [Q]

SD Card Problems With Clockwork Recovery​
Hi there XDA, basically everytime I have an SD-EXT partition on my phone (i always, always make them using Linux manually) if I format my SD-Card (which should only format the Fat32 partition, I run into a big issue. My SD-Card will un-mount, possibly format i don't know, then it won't remount. If I connect my phone to windows the SD-Card has all its partitions removed. Very strange?
Anyway I decided to switch to Oxygen 2.0.1 this morning, as it's a much more stable rom, and anyway I performed what I said above on Froyo 2.1 (DeFrost) and the SD-Card wouldn't mount, when I noticed that the SD-Card didn't have any partitions I formatted it using Windows. I then placed the update.zip file of Oxygen onto the root of my SD-Card.
I proceeded to Clockwork Recovery and selected the option 'Select .Zip from SD Card' and I was shocked to see something saying No Files Found. We I have tried everything to sort this out, and absolutely nothing seems to be working? I have used a Ubuntu Live CD to try and completely wipe and re-format my SD-Card which completed sucessfully, but no joy, i've tried all the options on Clockwork Recovery, nothing works, I used a 2GB SD-Card to install Oxygen and this worked fine, once the phone was booted everything would work including the 8GB Card if I switched them. I know I should just put up with this, but I need to fix this.
Does anyone know how I can get my card to work again thanks.

fix "can't mount /dev/block/mmcblk0p2 (File exists) error mounting /sd-ext/!.

I flashed a Leedroid 3.0 and it was just stuck in the boot screen. So tried to clear data and all thru recovery and i got this error "can't mount /dev/block/mmcblk0p2 (File exists) error mounting /sd-ext/!.
I downloaded gparted to repartition my 8gb sd card. I did a ext3 partition. When i plug back the sd card, the error still comes out in recovery mode. Any rom i flash gets stuck in Bootscreen still. I tried partitioning my 4gb sd card but it also gave the same error in the recovery.
please help. Been trying the whole day and still nothing is happening

Have you tried partitioning it through recovery? (If you have that option available)

I'd begin with reflashing a cwm recovery, cause maybe the problem is not your sd. In "mounts and storage" did you try to mount/amount sd-ext ?

I cant also mount/unmount sd ext. It says the same thing. can't mount /dev/block/mmcblk0p2 (File exists) error mounting /sd-ext/!. should i just buy a fresh new memory card?

What exactly is your recovery ?
Sent from my Desire using LeeDrOiD 2.4.1

flash clockworkmod recovery 2.5.0.7 . Im using a sd card now without partition. It seems to work with the rom. Using Leedroid 2.4.1 . If i use the original SD card and reboot it with it, its just stuck in HTC boot screen.

So you should just use parted again with your stock sd to make it work ...

Common error when card is not partitioned or wrongly partitioned. First make Fat, then make EXT.
http://forum.xda-developers.com/showpost.php?p=7279872&postcount=3

Thanks man. I was able to repartition. I made a wrong partition in gparted. Made a fat32 primary then the second one extended partition. From your post i made it primary also the second one. Now my rom reads the sd card. Thanks again.

Hmmm I had this exact same problem with LeeDroid 3.0.2... Trying to flash without wiping, had about 80 apps on my EXT3 partition... Got stuck on the white HTC screen for about 2 hours, gave up, pulled the battery, tried to flash the alignment zip, still stuck... tried to restore nandroid backup but then started getting this same error as you.
Thankfully was able to rescue all files from my SD card, format and partition again, then flashed LeeDroid 3.0.2 and restored a Titanium backup... everything running smoothly again! Phew...

May I ask how did you manage to do that?
EDIT:
Ok. Apart from the backup/restore issues that depend on having a healthy ext partition as I figure, the "can't mount [..] error mounting /sd-ext/!" problem is responsible for the "green HTC logo on the white screen freeze" also. So I've been trying to make it work all evening and this is what I found:
The Error (at least in my case) and the freaking "green HTC logo" freezez were generated because the Ext partition got corrupted in some bizarre and mysterious way. I have no idea how that could have happened, but I guess a small role in this ballet got played by the ROM itself and maybe even the nandroid backup built into the CWM (ClockWorkMod). It started right after I finished installing a fresh copy of the LeeDroid 2.4.1 and all my favourite apps (which worked flawlessly), rebooted into bootloader > CWM > nandroid and made the full backup of the system. Rebooting the device afterwards got me into the above mentioned freeze.
I tried many things, among which were flashing different ROMs and Radio images (without wiping though), but none worked. I just wanted to roll back to the previous state (because i've spent quite some time configuring and installing the 2.4.1) and it seemed impossible at that point. Browsing the recovery options got me into the Mount and storage section where I noticed the listed error with the ext partition. I thought maybe formatting will help - well, it didn't. After a couple of weird things I had tried, I've decided I should delete the ext partition (leaving just the fat32 intact). Creating a new ext partition from scratch seemed to solve the error. However this didn't solve the freezing. And the reason had to be the fact that when it created the nandroid backup images, the ext was already corrupt (or however unreadable), so the relative image was not written because it didn't see the source.
I doubt there is any way to fully restore my previously installed ROM with all of it's apps in place and in a functioning order, because the ext partition had data on it and now it's missing (hence the freeze).
Therefore the question: what could have gone so badly wrong to compromise the ext partition?
And another one: is the LeeDroid 2.4.1 ROM or the 2.5.0.7 ClockworkMod Recovery the culprit?
Sorry for the looong post. I look further to hearing from Lee, if his busy schedule allows it and thank him in advance.
Cheers!

hi! having the same exact problem right now... could you please help me how did you rescue all of your sd-card and sd-ext partitions? Thank you very much!

same problem on my N1, reparition to resolved

hi..
i got this problem too
i have clockworkmod recovery. pvt4.
cyanogenmod 7.1.
didn't make any partitions,
everything is by default as i got with cyanogenmod
s-on.
sd - 8gb, class2
yesterday my desire freezed.so i had to pull out the battery. but i couldn't turn it on till' i didn't wipe cache and dalvik cache.
When i selected wipe dalvik cache i got this
E: can't mount /dev/ block/mmcblk0p2
(file exists)
but it wiped it and my phone worked.
this appears even without sd card
it freezed after a week again but after a couple of reboots it works again but the error still exists.
i am newbie so i don't know what to do?

So I flashed a ROM which stuffed up my partitions somehow (also became S-ON, WTH?!).
I got 'can't open /dev/block/mmcblk0 (or /dev/block/mmcblk0p1) (invalid argument)' when trying to mount /sdcard.
I also got the aforementioned 'can't open /dev/block/mmcblk0p2 (file exists)' when trying to mount /sd-ext.
After literally 16 hours of head banging, I realised when I partitioned the SD card again that they were logical instead of primary. Partitioned using minitool partition wizard home edition.
Rundown:
I'm using LeeDroid v3.3.3 with clockworkmod recovery 2.5.0.7
Make sure you partition FAT32 first as primary, then ext3 as primary. LeeDroid says to partition ext3 1GB after FAT32, so e.g. my SD card is 16GB, I have ~13.8GB FAT32 | 1GB ext3
This fixed the 'can't mount /dev/block/mmcblk0' error, /sdcard is mountable.
You can now run .zip files from recovery (yay!). Throw alignment_ext3.zip on there and run it. You should now be able to mount /sd-ext.
Do a full wipe + Dalvik cache wipe (to test /sd-ext accessibility). For me it was back to normal and I'm currently doing a restore.
Always do a backup.

Can't Mount Sd Card in CWM

So i went to flash a ROM and now it says while flashing that the flash was aborted because the system can't mount the SD card. I'm using the newest CWM and have flashed stuff before. Not sure what to do, it wont let me make backups, restore, or flash anything.

Did you use the Mounts menu to try to manually mount the sd?
Also, Which method did you use to get into CWM?

Ya i went into the menus and manually unmounted and then remounted the SD card but that didn't do anything. I used the typical three finger method to boot into CWM like i always do.

i think
I believe this has something to do with the way in which the SD card is formatted I also cannot mount in to usb storage in CWM i get an E: error

Have you guys tried to "Reboot recovery" from the "Adavnced" menu in CWM, and then try to flash the ROM?

I've had this happen before, it was a formatting problem. The easiest fix I found was to back up SD-card data on your pc, reformat the card from the Android system, then copy your data back over. CWM should be able to mount your card now.

I had a problem with the mount dropping mid flash it was my sd for some reason was chipped I always keep backup files

Just flash another version of CWM and u'r done. I faced this problem after flashing Siyah Kernel v2.3 which includes CWM 5.0, and I tried all the methods online; formatting, error-checking, etc... nothing succeed!
Finally I flashed another kernel (Which includes CWM 4.0) and it worked fine.

Thanks!
Same thing happened to me just now... found this thread.. pushed new CWM in ODIN - Worked like a charm.. Fixed in 2 minutes..

Flashing another CWM (ACS recovery this time...) via Odin did not fix the issue. Going to try the format /sdcard fix and see... argh!
*Edit* aaaand that didn't work either. WTF... I literally just got this phone 2 hours ago... brand new.

delete the .androidsecure folder on your sd that worked for me formatting wont work if you put your files on the same with me because i always copied that folder along too

[Q] Can't mount SD card in recovery to flash a new rom, help!

Hi there,
I was about to flash a new rom on my Dinc, and right after I formatted /system, the sdcard became unable to mount and now I can't access the .zip for the new rom. I've tried flashing 3 versions of CWM as well as one of TWRP but none of them can access my SD card. I also reformatted it in my PC with no success. I currently don't have any operating system on it so all I can work with is hboot and recovery.
Can anyone help me fix this?

Did you format it fat32 with the pc? If the cards fine (can be used by pc and fat32) and recovery and hboot still cant find it, then id venture to say the sdcard slot is damaged or went out.
Using adb in recovery, you should be able to push a rom file to emmc and flash it from there.

I did format it FAT32, and the SD card is definitely fine. I don't think that the slot is the problem either because other things won't mount either.
Actually the only thing I can mount in recovery is /system, everything else is inaccessible. It was having mounting problems before which is why I decided to flash it with a new rom (was running Jellybean very poorly). I also tried flashing the original recovery, doing "clear storage" that way, and reflashing with CWM but it had no effect. During the storage wipe it said that /datadata doesn't even exist. It also shows errors that it can't mount the files /dev/block/mmcblk01 and /dev/blk/mmcblk0p2

This is what the log shows when I did the CLEAR STORAGE using the stock recovery
Restore factory NV setting...
Formatting DATA:...
E: format_root_device: can't find mtd partition "datadata"
Formatting EMMC:...
Formatting CACHE:...
Wipe ALL failed.
E:Can't mount DATADATA:recovery/log
E:Can't mount /dev/block/mmcblk0p2 (or /dev/block/mmcblk1)
(No such file or directory)

The same thing happened to me long back. What I did was that I cleared data, cache, and dalvik cache... Worked for me... You can try but i wont take any responsibility
