TICKET ARCHIVE -> Invalid Extent entry on Boot Camp Mac Partition
Paul Shankland - Apr 7, 2006 - 2:49 pm
HI - and Help!! :-) (thanks for any help at all!)
- 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!

I would try DiskWarrior and if you can't repair your partition with their startup CD, try Data Rescue II. Both cost money, but are downloadable.
Target mode won't work with a Windows PC, unfortunately.
Macdrive will in theory allow you to see your Mac partition while booted in XP, but if the file structure is badly damaged, if you copy files over, they may all be corrupt. I'd try DiskWarrior and Data Rescue II first.
HTH and please let us know what happens. Thanks.
