Paul Shankland Posted April 7, 2006 Share Posted April 7, 2006 HI - and Help!! :-) appreciate your advice! - I have a new (2 week old, ser nr sw86109p5vj1) MacBook Pro 2GHz (with 1GB Apple RAM added for 2GB total), 100 GB HD, and just put on Boot Camp - after updating to Tiger 10.4.6, and updating firmware to 1.0 - and installed XP Home SP2 in a 35 GB partition just fine (with drivers)...Religiously followed the procedures at: http://www.apple.com/macosx/bootcamp/ and got XP to run- it works great. But.... Going back to OS X - I get the Grey Screen! And after a TON of work setting up the Mac OS drive/partition.... I tried to boot from the Installation CD to get to Disk Utilities - and ran the repair - it got through 3 steps to checking catalog file, then gave me in red: invalid extent entry, volume check failed; below, "the underlying test reported failure on exit". I bought AppleCare, but they said merely to slick that partition and reinstall OS X, then update it to .6... Not good - I already have lots of important stuff on that HD.... I looked in to Firewire Target Disk Mode (per http://docs.info.apple.com/article.html?artnum=58583) - but I have no other Apple machines available (but I do have a Windows laptop with firewire...? can that work? Or can I try to burn an image to an external HD somehow?) - Or can MacDrive 6 ( http://www.mediafour.com/products/macdrive6/) let me "see" the OS X partition form the successful WinXP install you think?? While in Disk Utitilies off the Install CD, I saw the "image" dropdown, so perused that, and I _did_ see all my programs, files and directories at least apparently intact from that vantage point.... So at least I found which files I would loose on a reinstall - too many.... I rebooted trying Safe mode (per http://docs.info.apple.com/article.html?artnum=107393) - it whirrs then shuts down to black. No luck there. None in verbal mode either - in that it froze... looked like it mounted the disk ok (I am new to Apple but very experienced in XP, somewhat in Linux, so I am unsure the details). At starting virtual memory just after removing some swapfile folders, it gives a: panic(cpu 1 caller 0x0030F4DC): hfs: block mark free: trying to free non-existent blocks (22037139 16384 14942208) then debugger was called (panic), doing a bunch of backtrace and lots of hexidecimal frame addresses popped, then backtrace terminated- invalid frame pointer 0xbffffd48. Then it went to Darwin kernel version 8.6.1: Tue Mar 7 etc etc root:xnu-792.9.22.obj~1/release/I386 And hung on carriage return after there.. I rebooted to single user mode (using press & hold the Apple key and the S key), and ran /sbin/fsck -fy from the command prompt... Just for starters, the verbal startup showed no bigtime show stoppers I think - no kernel discrepancies, booted as singleuser fsck not done, root device is mounted read-only .... - if I should be looking for some particular failure in the verbage - do let me know... So I ran /sbin/fsck -fy ... and it ran: ** /dev/rdisk0s2 ** Root file system ** Checking HFS Plus volume. ** Checking Extents Overflow file. ** Checking Catalog file. Invalid extent entry (4,712) ** Volume check failed. localhost:' root# etc For grins I ran /sbin/mount -uw / did nothing; re-ran fsck - same result above. for more grins I ran sh /etc/rc and it cave the same stuff I got when I ran verbose mode, freeezing just after the Darwin Kernel banner again... ++++ Now, the problems with Boot Camp Beta are one thing, but I do have XP running just fine - and much software now there too... But I think there must be some small way to fix what appears to be just a small invalid extent entry, irrespective of Boot Camp - this is an OS X partition all by itself ... Is there? And as a plan B, how best to retieve what I can before a reinstall... Many thanks fr any ideas, help, options, pointers!

Paul Shankland Posted April 8, 2006 Author Share Posted April 8, 2006 Well I dropped the 100 Bucks at a nearby Applestore... and tried to boot from DiskWarrior - No Luck! The OS X partition will let me boot from the Install CD that came with the Macbook, but not DiskWarrior... it whirrs up, then just shuts down when I boot and hold C and/or C+Apple... And Oddly, in Bootcamp, when the original install disk is in the drive I can use a boot with Option held down to select XP, Mac HD, or the Install CD -- but when the DiskWarrior CD is in the player, it refuses to "show up" as a bootable option... I can see the DiskWarrior CD (and in fact the Mac HD) fine with XP started (and MacDrive6 installed on the XP partition - in fact I was (yeah!) able to rescue most of my "prized" files from the OS X partition using MacDrive6, off to an external HD) - Bootcamp even installed a program that allows me a choice to reboot into any available disk - and Diskwarrior _was_ given as an option there - but STILL would not reboot when the laptop whirred back to life. It went to the Apple Logo, the grey spinner popped up for only a second - then the machine (again) shut down completely... Since the Mac Install disk works ok (and came out before Bootcamp) - I am at a loss why Diskwarrior fails to boot the laptop on OS X... I wonder if it's a 10.4.6 problem and not a Bootcamp problem -- Anyone hav any further ideas?? Many Thanks!! Paul (desparate...)

Velvet Nightmare Posted April 8, 2006 Share Posted April 8, 2006 Just wipe it. If you're having errors that bad, you're going to have to. Install the MacDrive trial, get all the files you need, burn a DVD of them or back up to another hard drive, then wipe.
