Install Failed - Disk is damaged

At least one thing is incorrect. There must be a space after the fsck_hfs command.

The -r option is known.

The -t option is unknown to me.

Whilst the fsck_hfs(8) Mac OS X Manual Page is not yet updated for 10.7, it should be good enough for some of what people are trying in this topic.

S.M.A.R.T. is useful but not a panacea. It's possible to have badly failing disk or disk drive with no hint of a problem reported by S.M.A.R.T.. I learnt this the hard way a few years ago, thankfully without loss of data.

I figured it out: fsck_hfs-rf /dev/disk1s3 and it ran quickly and the last line said "disk needs to be repaired". Does this mean my hard drive is bad? I had absolutely zero issues until trying the Lion intstall. I am at a lost as to what to do next. I have reset p-ram multiple time and can not get my HD as an option to boot back into SL. If i click install on SL it tells me it will erase my data.In SL disk utility "verify disk" I get "invalid node structure", "the volume mac HD needs to be repaired" and "Eror: filesystem verify or repair failed" UG!!!!!!!!

I am no tech geek, but I tried to repair my disk. It looks like Lion created all kinds of conflicts in the Library. I repaired it, tried to install Lion again, and all the conflicts came back.

How I averted catastrophe: I threw OSX Lion in the trash bin. I booted up in Safe Mode. Then opened up System Preferences. Clicked on Start Up and it offered me to start up using Snow Leapord. I restarted the computer and it is working beautifully. Right now I am just saving everything I can externally.

Have handy a USB flash drive, then start from your Snow Leopard DVD. Whilst started from that DVD, use Terminal to run the three commands below. Save the Terminal output to a USB flash drive, then use Disk Utility to eject the USB flash drive.

Use some other computer to paste to this topic the results of the three commands.

diskutil list

diskutil info disk0s2

diskutil info disk0s3

Thank you

Hint

How to paste plain text, or code, in Apple Support Communities — a two-screenshot demonstration

Ok I will do that.and post I am posting using a PC laptop. in disk0s2 is the 0 the number zero or letter O? Also my disk is "disk1s3" so do I use that or what you have typed disk0s2???

iMac is currently running an Apple Hardware Test from the SL disk by entering "D" when starting. It "passed" with no issues on initial test and am now running extended test currently at 23 minutes with estimate of 30+ minutes with no issues. IF this passes can I assume I have a software instead of hardware problem??? I do not have anything backed up (stupid me!) and have a ton of pictures I am praying I do not loose.

I cant figure out how to paste to thumb drive??? I ran the first terminal and can copy but how do I past to thube drive?

Also my hardware test from the SL disk gave me the follow error

4HDD/11/40000004:SATA (0,0)

Exact same error with similar results..

MB aluminum 13" last model before discontinued

Botted with C with Snow leopard in mac.

can do disk utility doesnt finish verifying... i go to repair and it cant.

Tried doing to option command p r thing and that opned up lions disk utilities and there i could also verify but in lions i could not even CLICK the repair image...

i can physically not dismount in snow leopard or lion...

if i go to quit installation or w.e to go to startup disk it does not work at all.. not enough information on seleced disk

now i have been using this computer extensively all weeks.. what gives when all of a usdden i install lion and it pretty much explodes!?

edit: and if i do reinstall os x it says that disk is locked...

i have no restore to go by as my external hard drive was left in my car (like i said laptop) and it along with other things have recently been stolen.

Sounds like you are in the same position I was in, check out my post on page 3, you need to run fsck_hfs command in terminal while booted off your snow leopard disk.

http://www.google.co.uk/search?q=%224HDD/11/40000004:SATA+(0,0)%22 finds numerous pages with that error. Amongst the many:

Apple Hardware Test - Errorcode 4HDD/11/40000004:SATA(0,0)

Before reconsidering the possibility of a problem with Apple's installer, please:

prioritise the possibility of a hardware problem affecting your hard disk,or hard disk drive.

Thank you for reporting the detail!

There may be more user-friendly information on this subject but for accuracy, I will offer Apple's diskutil(8) Mac OS X Manual Page — not yet updated for 10.7 but comprehensive enough for many purposes. Towards the bottom of the page, the relevant section is DISK IDENTIFIER

The quicker answer for this particular post only: 0 is a number, the integer zero.

I do not have anything backed up

Your profile doesn't show your locality but I recommend the following company, near me:

CnW Recovery

If data recovery is required and not possible with what's provided by Apple, search the forums — you'll find many recommendations.

Hi all, I like everyone had all these same issues, and was stuck not able to install Lion and not able to go back into Snow Leopard. After hours of trying different suggestions, (resetting PRAM, holding different keys at startup, using Snow Leopard Disc to repair, etc) I came across one that finally worked. As per a suggestion on another thread of a different site, I used Disk Warrior to rebuild my hard disk, as Mac OS X had failed to fix it through Disk Utility. It took a little while to run, but when it did finish it corrected the issues. I then reran Disk Utililiy's Verify Disk and it came up clean. I then rebooted and Lion of course tried to reinstall itself, but this time I could select my main hard drive and it installed just fine. I am now up in running in Lion with 100% of my files, settings, etc. Hope this helps!

Sounds like a great idea. I am about to swap the hard drive with a new one and install SL and basically get back to an "out of the box" state then hook up the old HD as an external and see if I can pull files from it to the new hard drive. But...

I do not understand how to get Disk Warrior on the Mac that is basically not working. I can not get to the net to download so would I purchase a disk and insert it in the Mac and then get an option to install? Even with the hard drive error and SL OS not working fully? Or am I missing something?

Ok sorry for the confusion. I was lucky enough to have a bootable backup on an external drive that allowed me to download and run from within the OS, but Disk Warrior does have an option to run from a DVD, so that you can boot from the DVD to run their utility. Do you have another computer that would be able to download it and burn their recovery disc?
