Bricked? Cant Mount /Data in CW when trying to wipe

Please help! my system crashed so i restarted android and got into a continuous bootloop, then i went to CW mod to wipe and reinstall but i get the follow error
--Wiping data...
Formatting DATA:...
E:Can't mount /dev/block/mmcblk3p2
(Invalid argument)
Error mounting /data/!
Skipping format...
Formatting CACHE:...
Formatting SDEXT:...
No app2sd partition found. Skipping format of /sd-ext.
Formatting SDCARD:/.android_secure...
Data wipe complete.
It wont wipe or mount /data/
\
I am running windows 7, and have ADB installed for when i rooted my moto droid
is there a step by step tutorial or writeup that can direct me on the files i need to download and the commands i need to type to restore this sucker back to stock and try again?
use cw to partition the drive, search "partition" Its something like 2048 & 512 ..dont quote me on that though. Do a search, thats what I had to do to mine to bring it back

You could try using CWR to format the sdcard (internal mem). Go to Advanced and there should be an option there. I was getting this error at one point so I formatted with CWR and it seems to have resolved. I used the 4096M and 64M options when asked.
Then you should be able to flash whatever ROM you want with CWR.
Thank you Photonmedia for the help. I too had this problem and it was fixed with a format and re-partition. However, now I don't have a restore image on the Gtab. I know, I'm an idiot...Luckily, it finally booted back into CM6.1 and i was able to move a vanilla update.zip to the internal mem.

E:can't mount /sdcard

I have CM7 Nightly #23, with CWM v4.0.
I'm trying to flash #26, but I'm getting the "E:can't mount /sdcard" error when trying to select the zip.
If I go into the Mounts and Storage menu, and try mounting /sdcard, it gives "Error mounting /sdcard!"
It mounts fine when Android is running and also when mounting the phone as USB storage in CWM, so it's obviously not a hardware error.
Any ideas?
Follow those steps.

Searching the Cm7 Dev thread would have given you your answer...but the fix is right here.

ZTE blade in bootloop and clockworkmod seems broken

I recently flashed my device with a CM7.2 rom which seem to have gone wrong, as it is stuck in a bootloop. I can get into clockwork recovery with volume down, but it can't access the sdcard, it gives me "Error mounting /sdcard!".
I tried partitioning the sdcard which seems to work fine (ends with Done!), but formatting gives "Error mounting sdcard", "skipping format".
Trying to use mount USB storage gives the error "E:Unable to write to ums linfile (No such file or directory).
I'm having a hard time figuring out how to recover from this mess, as the device dosen't show in adb devices when I boot it with volume up and the sdcard dosent seem to be mountable.
Any suggestions?
In cwm, go to advanced : mounts and storage : mount /sdcard

Mi a1 unmounted /system and /data fs

My Mi A1 device is in a state that is stuck in the first logo boot screen and when I boot into twrp I get errors of failing to mount /system and /data. I have tried the methods of wiping the partitions through twrp but the proccess fails. I have also tried to switch the filesystem to something else but that proccess fail too. Is there a way I could create them from scratch via the terminal in twrp? I don't have the knowledge to do things like that in filesystems and my device is for me right now in a bricked state because of that. Any help would be greatly appreciated.
When I do the switch file system option of /system and /data from twrp i get the error 'E:recv error on uevent'
When I try to do a format I get the errors: 'Could not mount /data and unable to find crypto footer.'
'Unable to mount /data (Invalid Argument)'
'Unable to mount /system (Invalid Argument)'
Hey, have you got any solution for the problem because I have stucked in the same problem. If you got the solution please tell me.
