When I load roms, typically I will wipe the Cache as well, the Dalvik Cahce. However, since loading the new Cm9 Unofficial, everytime I try to wipe the Dalvik, i get "E:unknown volume for path [/sd-ext]".
Is this a problem and if so, how do i fix this?
I'm pretty sure it has always said that on every phone and every ROM I have used.
The dalvik cache wipe is not needed if you wipe the cache partition...
Guess where the dalvik cache is,
that's right.
The cache partition!
Btw, that message just means you don't have an external sd card installed.

True, the error message can be ignored,
but sorry you're wrong -- dalvik-cache is under /data partition
and the message will appear regardless of having an sdcard, it just means [/sd-ext] is undefined

hey, I installed the CM7 today by using the clockworkmod 0.8 (I used the VEgan 5.11 before )
I wipe cache partition, wipe data, wipe, wipe Dalvik Cache
but when I wipe Dalvik Cache, there is a error: can't mount dev/block/mmcblk0p2
anyway, I install the CM7 successfully... but I am a little worried about that erro...
so why this error appear? what is that mean?
do I need to fix this error and then reinstall the CM7?
sorry for so much naive question! thanks!
Solved. Mod please close.
Thanks for the help....
Just got a new Thunderbolt. Rooted. When I wipe Dalvik cache I get a line that says E: invalid directory or file. Is there something I need to do to my internal storage or sdcard first before downloading a new rom, wiping data cache dalvik and then flashing? Recovery doesn't seem to be wiping dalvik cache. Any help is apreciated. Thanks.
Hey! Let me tell you something.

Did you delete the cache partition first? I believe the dalvik cache is often stored there, so if you wipe the partition first, you'll get an error if you attempt to wipe the cache afterwards. Either way, if it isn't there, it shouldn't cause a problem with a new ROM.
I found a file named cache, it had 2 files. One was called download.apk, the other was Recovery.txt. The Recovery.txt file was just a log of my last flash. The download.apk would not open. It was 1kb. In the data dir. there is a David cache file. It has all the data from the user apps. I deleted the cache file but still got the error, then deleted both, and still the same. After reboot, both files were there with the same info. Should I re-root, format sdcard with a ext-3 partition then update to a GB Rom? Thanks

It always says that, for me at least. You have to do two clicks in Recovery for it to work, if you know what I mean. After I click "Clear Dalvik Cache" the first time, I get that "error" and a list of more options, one being Wipe Dalvik Cache, and the other 13 being the same. I click Wipe Dalvik Cache, and the feed at the bottom says Dalvik Cache cleared.
That is when.it looks for a EXT partition. If one was not create it will say that.
It is typically used for Apps2SD and by having them on the SD there would be a dalvik directory.

Hi all,
When I wipe the Dalvik cache in the recovery, I always get an error can't mount /dev/block/mmcblk1p2 File exists. Anything to be concerned about, and why do I get it (besides the file existing, I mean why does recovery even look at it)
Thanks.
i have read that wiping dalvik cache will clear some of your internal memory so my question is can i wipe dalvik cache via cwm or need wipe only when u flash roms?
Yes, you can use this option in cwm (you can find it in advanced). Only what must you remember, when you do wipe dalvik cache the phone will first run need more time to boot.

If ur hungry for more internal memory, install a2sd script, install a2sdgui & move dalvik cache to sd card. U wil get around 150 mb free internal memory.

Do moving dalvik cache on external sd card safe?
If the dalvik cache is on external sd card, do phone will run as usual when sd card is unmounted?

If you move the dalvik cache to the sdcard and unmount and boot, then the dalvik cache will rebuild in the phone memory when you boot, so boot time will be longer(the first time)

If it will create another dalvik cache,what will happen to dalvik on the sd?
What happen to the phone if sd card unexpectedly unmount?
I assume the advantage of using the full wipe zip is how fast it works. What else is recommended to wipe before flashing a new rom. What I have been doing is flashing the wipe zip, then formatting system, cache, and data, then wiping dalvik cache. Is all that necessary? Should I also be doing a full wipe/ factory reset? Thanks in advance.

I believe the zip you are referring to is Bills fullwipe zip. It wipes everything needed to flash a rom except dalvik cache. So, flash the zip, wipe dalvik, flash your rom.

Yes, sorry, its Th3Bill's zip, but I got it on Joker's site. So its normal for it to wipe superfast, like in a few seconds? What about formatting system, data, and cache, is that not needed either?

Nope, that's the three it wipes. And yes a few seconds is normal. Only thing you might wanna wipe is dalvik.
But, I mean there is the full wipe/factory reset, and then under mounts u can manually format each one. What is the difference between formatting and wiping?

For our usage, not much difference.. But technically, wiping referrs to 'deleting' everything there. Deleting makes something disappear, but doesn't make it nonexistent. It just tells the system that this space can be used for other things now. Until the the given sectors where the data resided are used to write something else, the deleted items technically still exist. Formatting, on the other hand, goes through every sector and writes over it with 'blank' data, securely making the data unrecoverable (for the most part).
How can you relate this to your phone? Well, if you are installing a new rom, wiping the data is sufficient. If you are getting rid of your phone for whatever reason, formatting is suggested.
Ok, thank u for the clear explanation.
