Repeated "Disk I/O error" after Waiting for DSMOS

Out of the blue, out of nowhere, my beautiful, stable hackintosh (on a Dell M1530, running 10.6.7) started getting stuck on the big grey Mac loading screen.

 

Verbose mode revealed that after the message "Waiting for DSMOS", the thing was then just repeating the message "disk0s3: I/O error" over and over again.

 

Booting into safe mode didn't work. Booting into single user mode and trying to use fcsk didn't work. I read here to try "sudo chown root:admin /", but that didn't do anything and instead just said "chown: read only" or something similar.

 

Any ideas? I really have no idea why it broke down, I don't remember installing any updates or changing any kexts.

Chameleon cannot boot optical media when it's installed to HDD.

 

You have three options:

 

1) Make your own Chameleon boot CD and use the 'swap trick' to boot the retail DVD. Visit the VoodooProjects forum, look for a post by me and follow the link in my signature. You need to register an account to download the attached files.

 

2) Use Apple Disk Utility to restore your retail DVD to a partition on your hard drive. This will be bootable with your present Chameleon installation. Very convenient.

 

3) Use any old Hackintosh distro you have lying around somewhere. These are bootable.

Doesn't look good. Did somebody drop your laptop? Use Testdisk to check your drive for surface errors.

 

Yeah I've dropped it a couple times recently, I wouldn't be surprised. It's odd that my Windows partition runs smoothly though, it's only the Mac side that's screwed up. Likely because I was booted into Mac when I dropped it.

 

How do I check for surface errors with TestDisk? From its options it looks like it's just a partition recovery tool.

wow. I think so, but it depends on the error message from Seatools. Make sure you try the repair options, if the drive has some bad sectors they will be marked as such and never used again. Some times this is enough. Last month I did that with a friend's old 40GB Seagate drive and it's back in action, now when you run a scan on it no defects come up, but the capacity shrunk a little bit.

 

Testdisk is not just a partition recovery tool, look again. There's a bootable iso you can download and burn if you'd like to see what it can do.

Fixed it! SeaTools wasn't working off the bootable for some reason, but a program called HDD Regenerator did the trick. It went through and fixed about 160 bad sectors. Restarted the thing and booted right into OSX.

 

Suhweet.

this is actually what i used with my usb, the problem is that is very slow and it detects like almost 5000 bad sectors
