Hacking Any way to save what appears to be corrupted isos (rips)?

[jdsmn21]

Hello everyone,
I have a situation - I suspect my WBFS partition and the ripped games on there became corrupt. Many of the games I had which previously worked fine would either lock up or bring up "disc error" screen. My first step was to use Modwii wizard to update all isos on my 4.1U machine, but that didn't fix. Then I noticed that a crappy game (Purr Pals) was listed as 8.x GB in USB Loader, so started to suspect something was up - there's no way that game could take up that kind of space!

Here's the steps I took to get where I'm at:

1)I connected my USB HD to computer and transferred a couple games to another USB HD with WBFS Manager - With USB HD#2 I still got the exact same errors, so I suspected my files are corrupt.

2)Downloaded WCDWM (which uses WIIMMS TOOLS) and selected "Repair" - this removed 71 games from my HD, leaving two remaining (the Netflix disc and WiiMusic - which are both small in size, and wonder if that is relevent). Here is the log from the operation:

3) In a panic, I found a thread about hex-editing the HD and was able to add enough 0x01's to bring the files back to where WBFS Manager can see them (and I can transfer them to my PC).

4) I'm back where I started however - it appears that I have about 71 unplayable game rips. I haven't tested each and every one however - only about three (by transferring to the second USB HD), but they still lockup or come up with the error screen.


Now my main question..... Is there anything I can do with my original HD (ie: any iso saving programs, or hex-editing, etc) or am I at the point where I just need to reformat and start over? Anybody know what happened to cause this? (so I can avoid in the future)

Wii is a 4.1U, HD is a WD MyBook (non portable/wall wart powered) 500gb partitioned to 200gb WBFS, 20 FAT, remainder NTFS. All isos updated last week (modwii), newest USBLoader GX (my main program) and newest CFG-loader.


Sorry for the long post, but I definitely appreciate any comments, suggestions, questions, or advice!

1.) I don't know what WCDWM did in detail (many options available). My tools detect overlays of discs and illegal wbfs block mappings. And such files are bad. It's a result of a wrong block allocation table. I have seen such failure many times. Therefor my tools always makes a fast check before modifying anything.

2.) Hexedit is not needed. First you have the "wwt recover" command. And then you can use e.g. "wwt edit ACT=0-1000" to activate the first 1001 slots.

3.) The commands "wwt verify" and "wit verify" can analyze disk images and find checksum errors (bad dumps)

Thanks Wiimm! I read through your links - good info, and great tool BTW. it looks like WCDWM ran this: wwt CHECK /dev/sdb1 --repair ALL, and 71 isos came up with bad blocks and were deleted.

What do you recommend to be my next steps? Should I reverse my hex edits and run the recover or edit command, or is that unnecessary?

 

[Wiimm]

run recover direct and then check without repair to have a list of damaged images.

 

[jdsmn21]

So I ran the tools suggested in the previous post, and have a list of "bad" images. Nevertheless I transferred the ISOs to my PC, and all but a couple measure 4,589,824 kb in size. Transferring them to a second HD - they still don't work on the Wii, but new rips from disc work (which makes me think I have my ios's and loaders in check).

I also downloaded Dolphin - the Wii emulator - and tried a half dozen of my transferred isos on there, which seemed to load and play fine (aside from a couple instances that had what I would assume to be 'emulator glitches').

So....it appears that the ISOs are damaged to where the Wii can't play them, but Dolphin can? Does that make sense??? Does the Wii have 'checks' on the games that Dolphin does not?

 

[PsyBlade]

just forget the bad images and rerip them
they are most likely partly overwritten and won't work well even if you get them to run

consider switching FS while the drive is almost empty anyway

I had a similar problem and was able to extract a few rips before they were fully corrupt. I wouldn't recommend doing so however, as it usually leaves the iso in some condition where it will either freeze or lockup during gameplay. I'd suggest reripping the isos and switching to Fat32.
