is there a homebrew program that chkdsk without connecting to comp? say ur on a road trip and ur memory stick decideds to corrupt itself.... and no comp is avail at the time.... chkdsk for homebreW?

**|-Anubis-|** · 05-21-2007, 10:04 PM

Not that I know of.

Where are you anyway?

**youresam** · 05-21-2007, 10:28 PM

Nope.

But Sony put a function in the XMB that allows you to reformat it..

**MániácX** · 05-21-2007, 10:36 PM

yoursam is right. just hit the format memory stick button in the settings menu.

**SG57** · 05-21-2007, 11:03 PM

How does chkdsk work anyway? I mean, why is it that it can delete/fix corrupted files where as the normal method cant?

**youresam** · 05-22-2007, 12:00 PM

Theres a function that lets you repair the corrupted part.

**antonyfl** · 05-22-2007, 04:32 PM

but say u have homebre won it that is beggin to be plaed................or important data u have to send to ur frriend in...errm.... alaska? u know... its basically just convenience i guess.... chkdsk for homebrew would be interesting and helpful indeed

**youresam** · 05-22-2007, 05:51 PM

And hard to develop. Do the file io / memory stick functions even allow that kind of low level access?

**antonyfl** · 05-22-2007, 09:42 PM

i dont know... it may be possible? maybe not chkdsk the function for PC but maybe some kind of Linux oriented command that does the same?

**MániácX** · 05-22-2007, 09:46 PM

if a memory stick is corrupted, will homebrew be able to detect the memory stick in the first place?!

**youresam** · 05-22-2007, 10:23 PM

flash recovery?

yes they do you can access memory stick as a block device you just need to unmount it and then port something like f sck (what's wrong about a disk checking utility to be banned :P)

**dx169** · 05-23-2007, 07:57 AM

Ok if you're on a trip and it worked before with no corrupted things it shouldn't decide to corrupt itself when it feels like it cuz the PSP doesn't like you smashing it's buttons in combos too much and decides to stop working. Just chkdsk before you go on the trip.

This is irritating me a tiny bit now.

chkdsk is not a verb.

chkdsk is a noun.

Also, I don't see much point in this application. The effort required to make it wouldn't match up with the actual usefulness of the application. Just my opinion though.

Depends on the level of corruption. I corrupted my MS with CWcheat once, it didn't finish writing a huge file so it left around 200kb free on my MS (formerly it was 100 megs) and there was no files which took that much

If the filesystem MFT (master file table) which contains all the entries for the files is ****ed up, then no, the memory stick won't be recognized.

well if someone was to make this app, i'd use it for sure. After all the psp is a portable device and you might not have a computer handy when your memcard corrupts

**youresam** · 05-23-2007, 10:44 AM

It doesn't corrupt often, though. Only if you do stupid things like save while in USB mode.. stuff like that corrupts it. Other than that, corruption shouldn't be an often enough problem that an app be developed.

So? "Google" is a noun. "Photoshop" is a noun. Languages evolve, get used to it. Command line programs are often used as verbs nowadays...

if the memory stick is corrupt will it even be able to run the homebrew...?

That was already discussed in this thread. Before you make a reply trying to start a new topic, read the thread. It makes you look less stupid.

Corrupted file systems don't behave properly with standard file I/O tools. You need to edit the file systems themselves to fix them.

Finally, someone asks the right question.

Make it part of the custom firmware, and yes!

Youresam: Don't be a ****. This question was not asked. The one that WAS asked was how the homebrew would be able to detect the memory stick if it was corrupt - not if the homebrew would even run in the first place.

FREEPLAY!

Hey! Long time no see... A chkdsk for a PSP ehh... hmmm sounds like a good idea maybe also have a defrag utility... I don't know about everyone else, but I have 2 MB free on Flash1 which should be more than enough room to hold a defrag utility and a chkdsk utility...

It's possible, but you need to find a open-source chkdsk and defrag utilities. Creating one yourself is very dangerous because you could screw up your File System.

**PSPJunkie_** · 05-24-2007, 05:36 PM

Pssht. FreePlay. Heh.

you could use even another memory stick to load it you don't need to flash it or whathever. and anyway most of the corruptions which happens while doing I/O on psp doesn't do such a corruption which couldn't let you load an homebrew already stored on it

Im sorry, there's a difference? In order to view homebrew details (title, icon, ect), it must load the homebrew file, which is no different than when it executes it.
So please Freeplay, don't be a ****.

... like f sck.msdos from dosfstools-2.8-2.src.rpm, for instance. I haven't taken a look at the source, but I'd guess that a port is as simple as converting from a command-line to PRX-based app, and changing the int21 file access layer (I presume it's done that way) into something using sceIoFile*.

Yes, there's a difference.

1: "Can this homebrew, after being run, detect the memory stick, since it's corrupt?"
2: "Can you even launch the f*cking homebrew in the first place, since the MS is corrupt?"

**antonyfl** · 05-25-2007, 04:49 PM

Ok so to sum it up (?):

1. Yes Homebrew can be with the help of CFW?
2. The homebrew can detect the memstick
3. Yes this Homebrew program is possible to bemade witht he help of f sck.msdos (etc)

that wut i got from reading... Also...
The point of this homebrew isnt the fact that it isnt useful and shouldnt be made, its for convenience. I would rather just run the program on my psp rather than go to my comp and plug it in. all of this is for convenience.

No, there isnt.
If it was ran, that means that the XMB must have detected and loaded the homebrew in order to run it. The second number has been discussed as being loaded from flash memory.
