[Q] Unable to mount data partition read/write

Hey
I'm trying to change from Prime to Revolution ROMs, but during wiping, I seem to be hitting a problem. When coming to wipe /data, it says it can't remove bootanimation.zip. I'm trying to go in via adb and do this manually, but it won't seem to let me mount /data as read write.
I'm using adb shell while in recovery, and it isn't giving an error message, just constantly staying as ro. This is using clockword recovery 3.2.0.1.
Anyone know what else I can try?
Thanks for your help.

Do you want to give it a try with root explorer?

Forgot to mention, since I've tried wiping, it now just bootloops. Recovery is all I can get into.
edit:
Just to make it clearer what's happening, I'll do it step by step:
- Load recovery, and open adb shell on my PC
-Mount data in recovery, check it in adb shell and it shows it as read/write
-Go to delete a directory or file, and it say's it's read only, check mounts and it's gone back to ro
-If I unmount and remount, it will go back to being RW, but then the same as above happens.
-My problem is when I try to wipe or format in recovery, it gives an error saying it can't delete a certain file

Managed to fix it now. It appears that while using the Superwipe Full script for Revolution ROM, the file table got completely messed up. I used parted to reformat the data partition as ext2, and I can boot now.

I've managed to get that awful Rom (Destroyer) Manager off of my TF101G and have got Rogue on via PERI and now I'm trying to flash the stock ASUS ICS Rom but can't delete the Dalvik Cache because I'm unable to mount /data
Code:
- - Wiping all user data - -
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure
Cache wipe complete.
Formatting /cache...
Cache wipe complete.
Wiping dalvik-cache...
Error mounting /data!
I'm assuming that /data is stuck on read only?
Manually fixing permissions and then mounting /data also shows the same error.

I have the same problem. I know what lead me to it.
Its an Asus SL101
I have cyanogenmod correctly installed. In order to install a megatron rom I downloaded their app called megatron apps. Trying to download a rom from them I got validation error at end of download and I make the stupidity of change the download dir from /mnt/sdcard to /sdcard and then when I restart again it doesn´t load and CWM recovery give me the same errors (unable to mount /data or unable to mount /sdcard when cleaning cache or trying to restore a backup ).
The only thing I have been able to do its to install Rogue XM Recovery 1.5.0 instead of CWM 6.x ) but the problem to apply an update or restore a backup persists.
Any idea ?

Aaargh.
After a year and a half of heavy CWM and TWRP usage, this has suddenly happened to me too, possibly after flashing the updated TWRP blob from Goo Manager (although that's conjecture at best). My ROM (RaymanFX' CM10 v6) is fine in everyday use - no problems whatsoever, but now I want to update, and my recovery won't let me.
In the hope that something simply went wrong during recovery blob flash, I successfully deleted TWRP and flashed a different recovery (latest CWM) from ROM Manager, but the new recovery can't mount anything either - neither sd card, data, or cache. The error messages are more or less identical to TWRP's errors. My system MAY be readable, but I can't backup or restore or flash anything anyway, so I don't dare format it.
I don't have a Windows PC, so I haven't tried Easy Flasher. I could try it on my work computer if there's no way around it and if neither OSX or Ubuntu can help.
Any suggestions?

What am I missing??

I was trying to install a custom ROM on my infuse, but bricked it. Now I ODIN back and can get to either the CWM recovery screen OR the Android system recovery 3e screen but here is where it gets weird, I cannot figure out for the life of me why I cannot flash from a zip file, I always end up with both recoveries telling me that my storage is not pre-paired yet. The read out goes some thing like this:
--Copying media files...
E:failed to mount /dbdata (file exists)
E:copy_dbdata_media: Can't mount /dbdata
your storage not prepared yet, please use UI menu for format and reboot actions.
Media files copy failed.
Please if anyone has a idea, shoot me your thoughts. Thanks in advance

What rom are you trying to flash?
You are on stock froyo, correct?
What method are you using to get cwm?

TWRP --> "Wipe" --> "Avanced Wipe"
Mark only 1 partition at a time and try
"Repair or Change File System" --> either "Repair" or "Change File System" (Most commonly "Ext4" but depends on phone)
What is your specific phone model?

Actually the problem is that the storage is showing 0mb and whenever I am doing anything like flashing other rom or trying to format any of the data ,cache or internal it says unable to mount. Even l have tried QFIL to flash the firmware but it's also failed. Please tell me something.

Is the stock recovery working?
TWRP 3 already tried?
Possible simple solution: but you will LOSE EVERY FILE on userdata.
Step 1: Install TWRP
Step 2: Go to Wipe box
Step 3: Select Advanced Wipe
Step 4: Check "DATA" and tap on "Repair or Change File System".
Step 5: Tap Change File System
Step 6: See original format on file system (EXT4). So turn to other (e.g. ext3) and switch back to original
Now /data is mounted back.
You can also try to erase the partitions using fastboot commands
fastboot erase cache
fastboot erase system
fastboot erase userdata

I have done all these several times and as you have said that change ext4 to ext3 then revert to original. I have done this and it is changed to ext3 but not coming to ext4 again. When I restart my phone then automatically they are changed to ext4.
And yes I have also flashed stock recovery and it is working. But now I am in TWRP recovery.
What should I do now???

HELP failed to unmount cache (device or resource busy)

at first im just failing at wiping cache.
now i cant even restore my TWRP backup.
it is saying "Failed to unmount '/cache' (Device or resource busy)
now my phone got no OS :crying::crying::crying:

I was facing the same problem.recovery twrp>wipe>advance wipe and then select system>repare or change size>change file system>select FAT
after doing it try to restore your backup and if you get error the only way flash your phone to the last build number(avalaible for your phone) and then install twrp recovery(last version).
restoring backup should be work with this method.

you can try this method
Mount>select partitions to mount : cache
select cache and after doing it go for restoring.

No need to restore /cache partition, exclude it The partition is used by TWRP that's why you can't unmount it.

I still have the same problem persisted. Can't wipe cache with this TWRP recovery. It says can't mount/unmont cache device or resource busy. Restore of the backup was impossible as well. Even when cache was excluded. Changing file types and repairing it also didn' work. In Mount cache is ticked permanently and it can't be unticked.
