Corrupted OSX drive repair

Anybody know some good utilities to fix a mac OSX drive with a corrupted directory structure? I used Techtool Pro to optimize the drive and it would not mount after that. Disk utility just gives me an error:

"Verify and Repair disk “Unicron”
Checking HFS Plus volume.
Invalid B-tree node size
Volume check failed.

Error: The underlying task reported failure on exit


1 HFS volume checked
1 volume could not be repaired because of an error"

I can't get it to mount and nothing I have will even try to repair it.

Try DiskWarrior, don't use it in OSX but it was the ultimate utility app in OS9.
Also Cocktail is a must have for OSX, run it ones a week and your MAC will keep on going.

Apple's deft Leopard

Ellen Lee, Chronicle Staff Writer

Tuesday, August 8, 2006

Apple Computer boasted Monday that it has completed its shift to Intel chips, unveiling a high-end desktop computer and previewing the next generation of its operating system, a combination that could help fuel the Cupertino technology company's continued resurgence.

Chief executive Steve Jobs, speaking to more than 4,200 developers at the start of this week's Apple Worldwide Developers Conference in San Francisco's Moscone Center, said it took Apple less than a year -- 210 days -- to move its computers onto a new foundation of Intel semiconductors. The company hopes the switch, along with its forthcoming operating system upgrade, code-named Leopard, will help it gain market share against computers running rival Windows systems.

The announcements come as Apple continues to take advantage of its market-leading iPod digital music player and its key role in the digital lifestyle explosion, regaining some of the ground it lost years ago to the rival computer manufacturers and Microsoft Corp.

It isn't surprising, then, that throughout the 90-minute keynote speech, Jobs and other Apple executives didn't hesitate to poke fun at rival Microsoft and its lengthy efforts to release Vista, the updated Widows operating system due early next year.

Apple has released five iterations of Mac OS X in the past five years and plans to introduce Leopard, the latest version, next spring, Jobs said. "What has our competitor been doing?" he said. "They've spent the last five years working on (just Microsoft Vista)."

Microsoft spends $5 billion a year in research and development, only to copy Google and Apple, Jobs added. "It's a good example of how money isn't everything."

Notoriously secretive, Jobs said he plans to keep some of Leopard's new features close to the vest for fear they could turn up in Vista. In fact, some of Vista's features look remarkably like Apple's current operating system, Tiger, Apple executives said, down to some of its color schemes.

"They've spent the last couple of years copying something we shipped years ago," said Brian Croll, senior director of Mac OS X product marketing.

But Apple did reveal how Leopard will have the ability to back up all computer files automatically, as well as go "back in time" to retrieve old copies or deleted files.

Apple's new Mac OS X also features a program to create personalized stationery in e-mail, such as embellishing it with photographs. And it will also include new online chatting elements such as presenting a slide show or video during the chat and changing the videoconferencing backdrop so it appears that the user is on a roller coaster or in front of the Taj Mahal.

"If customers see the new features and how (Leopard) is light-years ahead of Vista, they have to consider (a Mac)," said Tim Bajarin, principal analyst at Campbell research firm Creative Strategies. "This leaves Vista in the dust."

Jobs also introduced the Mac Pro, a top-of-the-line desktop computer using Intel's latest chips, the Core 2 Duo. Packing two of the chips, the Mac Pro is three times more powerful and two times faster than its predecessor, the Power Mac G5, and offers up to 2 terabytes of storage, according to Apple. On the business side of things, Jobs premiered a new server using Intel's latest chips, the Xserve, using two Core 2 Duo processors, as well.

The new Mac Pro is listed at $2,499, not including a monitor. The suggested monitors to accompany the machine are priced between $699 and $1,999. The Xserve goes for $2,999.

Apple says the Mac Pro and Xserve are competitively priced. That customers must pay a premium for a Mac "is a myth we are going to continue to bust," said Philip Schiller, Apple's senior vice president of worldwide marketing.

Apple can offer more-competitive pricing now that it's using Intel chips, said Richard Shim, an analyst with research firm IDC.

"They addressed one of the biggest criticisms, which is price," Shim said. "This is a start. Over time we could see a trickle down to the consumer."

Jobs did not address the company's role in the continuing stock options backdating scandal, in which the company said last week it had found additional irregularities and warned it may have to restate its earnings.

Nor did Jobs utter a peep about Apple's popular iPod, instead directing the presentation at the conference's audience, the software and hardware developers that produce products for the Mac platform. Prior to the show, rumors were circulating that Apple would introduce a new iPod with Wi-Fi, a phone or new screen capabilities.

A few of Leopard's features
Time Machine: Automatically backs up computer files and programs, as well as retrieves old and deleted files.

Chat: Can present slide shows and videoconferencing simultaneously during online chat.

Mail: Adds e-mail stationery, including the ability to personalize it with photographs, and features new to-do and reminder features.

Spaces: Packages software applications together so multitaskers can hop from one job to another.

Spotlight: Searches for files on other machines on the same network.

Boot Camp: Allows users to run Microsoft Windows operating systems on the Mac. Will be updated and packaged in Leopard.

Will Diskwarrior do it? Might be worth a try.

Diskwarrior tells me the drive is too severely damaged.
