chkdsk on Android?

Bad day today. Why? Because this morning I decided to try out one of the Eclair roms before leaving for work. I flashed it, tried it and then looked at the time. After noticing that I had only 15 minutes before having to be at work I decided that it was time to lock up my computer and take off... but first... I need to restore back to a stable rom. So I restarted my phone and using switchrom I recieved an error of some kind. Not a big deal because anytime I flash a new rom I do a switchrom -s, bart backup AND nandroid+ext backup. Then everyday I use a bat script to automatically mount my sdcard and back it up to my pc just in case I need to format my card and restore everything later. Which brings me to the point of this thread. I was able to restore CM-4.2.8.1 but it was booting VERY slowly (about 15 minutes) and I noticed that it still said "Checking for errors" in the status bar. I left my phone on the charger and checked it later and it said that my sdcard was damaged. I have absolutely NO computer access and my phone is running WAAAYYYY to sluggish to use. So I just turned it off and put my sim in my old Tilt phone and used that for the day.
So... throughout the ENTIRE day I was going through Android withdrawls. I needed my G1. It was killing me.
So my question/idea is, is there a way to do a chkdsk on the fat partition of from the recovery menu or from terminal? I did a little searching and came up with something called dosfsck. And I looked in the /system/bin/ directory and saw something called fsck_msdos. Can we use this to repair the errors that the system finds on the sdcard? If the OS can scan and detect errors, then why can't we have an option to fix them? Instead of having to use a computer at home or the office.
Any thoughts? Thanks.

The thing is that is part of the windows OS, i know cause i use it to check for errors on my HDD or SD cards time-time. Im not sure if linux or distro or whatever its called has that feature avail.
Oh and i had that prob before where it was devastatingly sluggish.

Uhhhh... is that a paraphrased version of what I said in the quote? LOL.
Here... I found this: http://linux.die.net/man/8/fsck.vfat
I don't see why it can't be implimented somehow into a recovery.img to avoid future problems. It'll basically be like e2fsck but for fat.

Oops sorry about that, didnt think anyone would notice.
Maybe you should check that up with Amon_RA?
I usually use my SD reader to check for errors before i flash a rom.

Yeah I guess I'll do just that.
I did find this too:
http://www.netmite.com/android/mydroid/donut/external/dosfstools/doc/README.dosfsck
So it looks like someone had the idea already. I wonder why it's never been implemented.

Copy the files to your pc, then erase the partition via console.Then do the error check again. I think its having trouble since you have a lot of files on your sd that must be zip or maybe you have a .img

I think it was Vista. I never should have used the error check option in the disk properties menu. I just tried it again using dos (chkdsk f: /R) so it actually tells me what it's doing. The error checking tool in vista is just like the defrag tool. You have absolutely no idea what's going on or how much longer it's going to take. Sucks.

I upgraded to 7
But i did like vista because of the HW support and eye-candy. I do wonder what its checking while it does that though.

What is this?

On my SDCARD, I have a bunch of these: DiskCacheIndexXXXXX.tmp where XXXXX is a 5-digit number. What are they?

Anyone know?

yeah you can delete them. Their "just" caching to make some things faster..
if you want to be sure that nothing bad happens after deleting them copy them to another folder. You can move them back later if you want

For me its a 0 byte file so its probably only using the file name to store the last used cache index value. I've seen many in the past and those must have remained due to crashes/unexpected reboots.

[RELEASE][NANDROID] Rooted Factory-Stock ROM

Hi all!
Well, thanks to everyone for their donations-- without you, this wouldn't be possible.
I present to you, one stepping stone towards custom ROMs: the shipping ROM on the device, backed up as a NANDROID.
What is this?
This is the shipping ROM on the device. There are no changes to this ROM besides being rooted.
Click to expand...
Click to collapse
How do I use this?
Extract the contents of this file to your SD card (external SD card) under
Code:
/clockworkmod/backups/
and you will end up with a
Code:
/clockworkmod/backups/revo_stock
folder.
Run Clockwork on your device, and select "Backups and Restore" then "Advanced Restore". Select "revo_stock" as the backup to restore, and choose to restore ONLY "system".
(You can also restore boot.img, but it is unnecessary, and I only left that in there for future use.)
Click to expand...
Click to collapse
What does this backup include?
This backup ONLY includes /system and boot.img. There is no recovery.img in this backup, nor is there a /data or /cache.
Click to expand...
Click to collapse
Will I lose my apps or information if I restore this backup?
No you will not, this backup will not touch your /data partition.
Click to expand...
Click to collapse
Why is this useful?
Accidentally erased something important in /system?
Removed something and now 4g Hotspot doesn't work?
Restore this, and it'll fix that... of course all the stock OS will come back, but hey-- you get a second chance

Extract through windows and put on your SD card in the proper folder.

its telling me that i have a md5 mismatch!!! i will try downloading it again.

Thanks cube please keep up the hard work! I wish I could do something to help other then sending some $$$ I would love to help bring the revolution along.
Viva la revolution.

Did anybody use this yet. i tried and it says my md5 does not match. i tried numerous times

Haven't tried it yet but I checked the MD5 against the images and they are correct.

Ah, sorry, forgot to state select "Advanced Restore" or whatever it's called-- JUST restore system.img.
If you select "Restore" it looks for the /data and recovery.img in the nandroid.md5 file, and when it doesn't find it, it errors out with an md5 error.
I'll edit the instructions now...

Just tested this. I can't advanced restore the system.img either. Comes back with MD5 mismatch. I can restore my own backups without a hitch however.
[Edit] I forgot to mention. There's a carriage return on the Rooted Factory-Stock ROM MD5 file. Removing it didn't seem to matter. I was thinking that maybe it was the culprit.

Agh! you just gave me the answer... I saved it in windows, rather than linux, so the line endings are wrong...
If you're able to, just open the file nandroid.md5 in Notepad++ or something like it, and remove the extra blank line, and change the line endings to UNIX style.
Thanks, I'll re-upload the .zip when I'm on a faster connection.
The actual .img files themselves are good, though.

thanks thecube, it worked with the notepade++ steps and unix style.

re-uploaded. Should work just fine now.

Is there a version of this with everything? In other words, not just system but data, etc. I somehow am stuck in CWR...don't have a nandroid backup. I pushed this to the right place on the SD card, did the system restore, but it still repeatedly boots into CWR. Is there anything that will do a FULL restore instead of just system?
Thanks in advance.

Hm, so you did a data wipe from within Android. Yep, that'll get you stuck in CWR, but it's not a problem with the backup, it's that the LG bootloader isn't happy with Clockwork.
When installing Clockwork, did you make the p8 backup?

so im having the same problem i even started a thread too but im an idiot and didnt make that p8 backup because the md5sum didnt match so i stopped there but clockwork still seem to flashed to the phone now im in clockwork everytime i boot up was wondering any way to work around this if not guess imma just get a new phone until there is a way

There is a way, I just haven't written it into an easy-to-use program yet.
For now, if you haven't made a p8 backup, the easiest method is for you to come on IRC and have me adb into your phone and fix it for you.
If I get a spare moment though, I will work on a stuckinclockwork.zip that you can flash using clockwork to get you out of clockwork.

Thats a link to the CRC of the test ROM, someone pointed that out to me earlier, thanks though. I'm on to looking for a dd of the system image, final thing I'm missing. All I have found so far are zips of the files which isn't what I'm looking for.

no but if you use full Linux...ie able to boot Linux up on its own and not through windows then u can access system files that way as it loads both the system and sd partitions up giving full editable access....not for the faint hearted though...even i don't like using that way lol.
And now as your getting a boot loop, which i did when adding both Xperia and HTC ringtones together found out, the only way is to wipe your rom and start again.
as a reference for next time....please do a backup!
ive given you the best options i know off....and i built the roms...i didn't expect someone to do what you just did...or i would have warned you off from it as i found out the hard way...just like you have.

no Linux must have its own drive.....putting it on usb wont allow you to do anything..
you have to install Linux onto a hdd an fully install it, takes a few hrs,
reason being, you need Linux to see and do everything without windows, running of a USB won't allow you to edit anything, just have a play to see if you u want it installing.
then you require the additional files/drivers to make your phone become recognizable within Linux, then you plug your phone in and up comes both partitions..
