[Q] E:Can't mount /dev/block/mmcblk0... - Desire Q&A, Help & Troubleshooting

So my desire is stuck.
Rooted, running Redux 1.2, went to use it yesterday and the screen wouldn't turn on.
So I took the battery out, replaced and tried again, and it was stuck on a loop on the Redux boot screen.
Took the battery out and replaced again and booted phone into recovery, and tried to backup (or restore) and got the message:
E:Can't mount /dev/block/mmcblk0 (or /dev/block/mmcblk0p1)
(No such file or directory)
Can't mount /sdcard
So now can't boot into the phone and can't do anything in recovery it seems.
Anyone have any ideas please?

Your SD card might be corrupted. Test it to see if it is ok.

Boot loops and CWM issues

Hello all,
i have been around on the site for a while reading, learning, and rooting my DInc. I have SkyRaider 3.5 w/ stock kernal. Currently running CWM 2.5.0.5. I was going to dip into the realm of setting CPU settings for different functions. I DLed SetCPU from the market and installed. i figured this would be a good time to do a backup through CWM in case i eff something up. after the backup completed, i selected the "reboot system now"
Upon rebooting, it loaded into my lock screen with the stock background and clock, not the ones i had before the backup process. when i did the slide unlock, it would just go to an all white screen with the htc green logo in the middle, and all my buttons but the power button were useless. strange i thought.....so i pulled the battery and proceeded into the CWM again to restore to a previous backup. got into CWM just fine, but now i had 5 message lines at the bottom of the CWM screen:
E:Cant mount /dev/block/mmcblk0p2
(file exists)
E:Cant mount CACHE:recovery/command
E:Cant mount /dev/block/mmcblk0p2
(File exists)
E:Cant mount CACHE:recovery/log
E:Cant mount /dev/block/mmcblk0p2
(File exists)
Then, i go into the backup and restore option, and select restore, it kicks me back to the main menu with 5 more messages:
E:Cant mount /dev/block/mmcblk1p1 (or /dev/bloc
k/mmcblk1)
(No such file or directory)
E:Cant mount /sdcard
E:Cant mount /dev/block/mmcblk0p2
(File exists)
E:Cant mount CACHE:recovery/log
E:Cant mount /dev/block/mmcblk0p2
(File exists)
I've tried doing a wipe data/factory reset, and it gives me a bunch of mounting errors and basically skips all format, then kicks me back to main menu in less than 3 seconds.
I've done a fair amount of research for this and can't find anything related to the DInc for this issue. Seen it on a few other devices (earlier droids) but not sure how much that info pertains to this device.
unfortunately i do not have a micro-sd card reader on my computer, so i have not tried re-flashing my ROM since i do not have a ROM on my SD card, not sure if it would be of any use since it sounds like my SD card is not mounting properly.
I will probably go out and buy a universal card reader (should come in handy) as well as a second SD card in case it happens to be the SD card that crapped out.
I figured I'd get this up here anyways to see if anyone can help.
Thanks so much for any advise or fixes you may be able to offer!

update
well, i managed to do a couple hboot updates and basically return my phone to the way it was when i got it from the store. i have no idea what caused it, but the original sd card still works, albeit reformatted, and the phone is functioning perfectly so far. I'm still curious to see if anyone had any ideas about what happened. sorry i can be of service to troubleshoot since i fixed it (the long way). my phone is too vital and i have travel coming up.
Thanks,
Trey
When I tethered my incredible to my pc I would get errors. I've had to actually run defrag on my sd card. I actually have several Micro sd readers but I was lazy and did this after tethering to my pc. Seems to have fixed the problem
So, I decided to try to go back to root last night, with the help of Preludedrew. rooted using unrevoked3 and updated to CWM 3. when it was all finished, it left me in CWM recovery and i had new E: errors:
E:Can't mount /dev/recovery/log
E:Can't open /dev/recovery/log
E:Can't mount /dev/recovery/last log ?
E:Can't open /dev/recovery/last log
when i would try to mount cache or sdcard, it would still fail, and when trying to load zip from sdcard, it would error in trying to mount sdcard.
with some more help from drew, we tried using adb shell to mount/access some partitions, and the mmcblk0p2 (i think) could not be found on the device.
thankfully the phone still booted this time, but i went into the phone settings under SD & storage...and the sdcard was there showing my 15GB of total/available space.
But....under the internal phone storage section, it said "unavailable" for both total space and available space.
so the only thing we could somewhat deduce, is that the internal phone memory has crapped out, thus when i RUU'd (?) back to stock, it could not find my phone internal storage so it just reassigned my sdcard to the 0p1 block, and where the sdcard should be in the 0p2 block there is nothing. Hence why cwm cant find anything related to my sdcard since its looking in the 0p2 block.
so now that i'm back to stock, i'll take it to the verizon store today and see what they'll do about it since the internal memory seems to be crap. i have insurance, so i dont think it will be a problem getting a new phone, unless they want to try to replace the internal memory, which is fine with me.
unless anyone has any other ideas?
sorry for the noobish verbage, i'm trying to remember what i all did at 1230 last night.
Thanks,
sorry for the quick reply, but i just had the idea to try mounting my device as disk storage, since it should come up as 2 drives (internal phone and sdcard) on my computer
both drives show up under my computer, sdcard access is fine, but when i try to access the other drive, i get "please insert a disk into drive G:"
and when i switch back to charge only, it will only say "preparing sd storage" and doesnt do "preparing phone storage" like i thought i remember it doing when it was still good.
I guess just another reaffirmation that the storage space is crap.

[Q]

Hello,
im in some big trouble.
I tried installing the new sense gingerbread rom.
It would not boot and i accidently formatted my sd card.
Now i cant boot the rom (loops at the android splash logo) and can no longer get into clockwork recovery.
All i can do is get into standard android system recovery.
if i use apply sdcard: update.zip i get the feeling it tries to go to clockwork
it says: e:cant mount /dev/block/mmcblk0p1 (invalid argument)
Is there a way to get this phone again...rooted or unrooted?
Please help me
Maybe to save yourself time you could just run an ruu and it will return you to stock. Then you just root again.

[Q]{FIXED!} E:Can't mount /dev/block/mmcblk0p2 {FIXED!}

Hi all. Got a bit of a problem. I have been using InsertCoinGB S2.1 ROMs for a while now and went to flash v22 this morning. Decided I would also take the step of updating my CWM to 3.0.2.8, as well as ext3 alignment, at the same time.
So, steps taken were Nandroid backup, apply update.zip, flash alignment_ext3.zip, flash ROM. All seemed to go well, but got stuck at splash screen. Pulled battery and got back into Recovery, then tried to restore Nandroid...
Ended up with
E:Can't mount /dev/block/mmcblk0p2
(File exists)
Error mounting /sd-ext/!
Skipping format...
E:Can't mount /dev/block/mmcblk0p2
(File exists)
Error mounting /sd-ext/!
Help!! I am pretty sure I have stuffed my SD, but hopefully not the whole phone. I have an 8gig at home that I was using prior to current 16g...I might be able to swap that in, just means I will lose all data from past week, which is not so bad...
I have done a fair bit of googling and searching here, but most remedies seem to rely on being able to boot into ROM and repair thru ROM Manager or GParted etc, but I am unable to get past Recovery or splash screen. I am S-On, btw and had 996mB Ext3/13.xFAT32...
Any ideas??
Cheers.
EDIT: Fixed. Phew! Was able to run home at lunch and thanks to clunky old Dell laptop, I found that my SD was not dead, just wounded. Had a GParted disk ready to go, so was able to format Ext3, boot up and flash Recovery. Will try to flash v22 again later...

Use AmonRA instead of CWM.
Your phone is a PVT4 model probably. Or use newer version of CWM.
