    Help! Data loss.

    I wanted to reset the view settings for all folders, so I followed the advice posted by someone on the Apple forum. I opened Terminal and entered: rm -rf .DS_Store / The process took a long time, my computer became unresponsive, and it eventually locked up. When I restarted, I just got a flashing "?". I used my emergency partition to boot up the computer and not only was my internal HD wiped (except for a few empty folders), but my entire 1TB external backup drive was empty too. My entire life was on there! I understand that modern file systems have backup file allocation tables. Is it possible to recover what was there using those? I hear that some rescue apps are unable to retrieve the original filenames, but they should all still be there right? I'm keeping the affected partitions unmounted to preserve them. Which tool is the best for my situation? I know of FileSalvage, Data Rescue, and Disk Drill. Thanks.
  2. Has anybody tried making a minimal, bootable Snow Leopard disk? I don't mean the installation DVD. I don't mean using the normal installer and choosing the basic install (still bloated). I mean a fully functional operating system with just selected components, to run on a flash drive or similar. Like this one by Brad Bergeron (10.4) http://tech.bradbergeron.com/guides/howto-install-and-boot-os-x-on-a-flash-drive/ or this one by some OSX86 guys (only 2.5GB): http://www.insanelymac.com/forum/index.php?showtopic=144128

    Triple-boot external

    Very helpful! Thank you. By loading order, I meant do I need to install MacOSX first, then bootcamp, then rEFIt, then Windows etc.. By the way, is there a file system that can be read natively by these three OS's?

    Triple-boot external

    I would like to set up my external Firewire HD, so I can boot any OS on my Core Duo MBP. In addition to data storage, I would like to have partitions for MacOSX, Windows XP, and Linux, room to add more later (ChromiumOS, "Live" tools, future Windows) and the ability to choose at bootup, including other external media. I've started doing some research around how to set this up, and I found guides on how to do specific parts, but I'm having trouble bringing it all together. So if you think you might know how, I could use some help. I would like the setup to be as versatile as possible. These are some of the questions on my mind: Is this even possible? Which bootloader should I use? Will I need more than one? In what order do I load everything? Will Ubuntu work properly or is there a better distro for my hardware?
  5. I am copying data from one external HD to another via FW800. They are daisy chained together like so: MacbookPro =---= LaCie =---= iomega. Because my 1st gen Mac only had FW400, I connect them through a FW800 ExpressCard. According to Wikipedia, "FireWire 800 ... and corresponding products allow a transfer rate of 786.432 Mbit/s full-duplex" (98 MB/s). Both these external HD's are dual-disk 7,200 rpm RAID0 configurations. The LaCie Big Disk Extreme (16MB buffer) features boast "Burst transfer rate up to 80-90MB/s in FireWire 800". Macworld reviews of the Iomega Mac Companion (8MB buffer) report rates up to 79.6 MB/s. Am I correct in assuming the limiting factor in throughput speed is the drives themselves which aren't able to saturate the interface? I used iStat Menus to monitor the HD activity and the peak read/write speed is 22.50 MB/s. Is it because they're daisy chained? Would I be better off with one HD plugged into the ExpressCard and one to a native FW400 port on my Macbook? Can anyone shed some light on as to why my files only transfer at a quarter of the full rate? Cheers.
  6. Lets say I have a library of MP3 music in a directory, and I have some external storage (SD card, USB flash drive, whatever...). Is there an App, script etc. that will fill up the storage device with random files from my music library? The SD card does not show up in iTunes. A Google search didn't turn up anything EDIT: I just found a perfect little free Java app. It's called Mix2Stix It has a simple, easy to use interface and works on any platform (Windows, Linux, Mac...), with any storage device, and any file type. What more could you want?
  7. *bump* Reinstalling OS doesn't work.
  8. It's totally unusable when flipping through many images. Operating system: OS 10.6.5 - completely up-to-date. Clean install onto formatted HD. Preview.app version 5.0.1 Hardware: Model Identifier: MacBookPro1,1 Processor Name: Intel Core Duo Processor Speed: 2.16 GHz Memory: 2 GB Boot ROM Version: MBP11.0055.B08 SMC Version (system): 1.2f10 Chipset Model: ATY,RadeonX1600 VRAM (Total): 256 MB EFI Driver Version: 01.00.068 Other image formats work fine. Other apps open JPEGs instantly. I had Tiger before, and JPEGs would load instantly. My hard drive is healthy. Console doesn't show any unusual messages. I tried turning QuartzGL on and off, system wide with the terminal command sudo defaults write /Library/Preferences/com.apple.windowserver QuartzGLEnabled -boolean YES I tried creating a new user account. I tried copying Preview.app from the install DVD. Here is a screen capture I made of the problem: http://www.youtube.com/watch?v=ylpCi7KtT3s Here is a screen capture someone else did: http://dl.dropbox.com/u/5803292/previewspeedtest.mp4 Here is him performing the same task with the same hardware in OS10.4: http://dl.dropbox.com/u/5803292/tigerpreview.mp4 I get mostly ignored on Apple.com discussion forums. Kinda disappointed and frustrated here.

    home and end keys do not respond

    You're right. In Safari the keys jump you to the beggining and end of a web page. But, for example, in Textedit, or as I am typing this reply, they do nothing at all. I hope they implement the start/end of line capability in future OS updates. Thank you for you feedback.

    Adding RAM

    So I ordered the 1GB stick from Apple and everything is hunky dory. I noticed the difference in performance right away. One thing to mention though, is what I received from Apple was simply Micron brand RAM. You can get the exact same product from a 3rd party vendor and save some bucks. Just match up the part numbers. Cheers.
  12. oes anybody know how to make the 'home' and 'end' keys work please? It would seem like Apple dropped the ball on this one. Macbook Pro 15" 2.16 GHz Intel Core Duo Mac OS X (10.4.8) Apple Bluetooth wireless keyboard
  13. just purchased an Apple wireless keyboard. When I launch the 'Bluetooth Firmware Updater' included on the software CD, it sits there with a stationary barberpole progress bar and 'Status' reads idle. When I click on the 'Update' button, I get a dialog saying "Missing Firmware. This version of the updater is missing the firmware file. Cannot proceed." When I quit the updater, it says "Firmware Update Failed. The Bluetooth firmware has not been updated successfully." I tried to download a fresh copy of the updater from Apple's website and ran it with the same result. What is going on here? Macbook Pro 15" 2.16 GHz Intel Core Duo Mac OS X (10.4.8)

    Adding RAM

    Munky, What is your geekbench score actually measuring? Because adding more RAM to your system will make it feel faster regardless of whether it's using dual channels or not. I did some research and purportedly the Macbook Pros use the Intel 945 family of chipset. I checked Intel's specsheet on it: http://download.intel.com/design/mobile/da...ts/30921903.pdf Under processor support: "32-bit interface to address up to 4 GB of memory" Under system memory support: "Maximum Memory supported: up to 4 GB at 400, 533 and 667 MHz" Indeed, according to the binary system 32 bits can address numbers up to 4GB: 2^32=4,294,967,296 Evidently, chipset has a mapping limitation which limits it to 3GB, which still doesn't explain the 2GB limit on the Core I Duos. Also, interestingly, that same specsheet says: "256MB, 512MB and 1GB memory technologies supported" So what about the 2GB sticks the C2D MBPs come with? Further, the website here http://www.anandtech.com/printarticle.aspx?i=2740 claims that using a dual channel memory configuration provides no advantage whatsoever over a single channel config of the same capacity, due to the FSB bottleneck.

    Adding RAM

    Lately I've been finding that I am waiting a lot for things like video processing, multi-tasking, etc. so I want to upgrade, but I want to know all of my options first. I know there have been posts about RAM upgrades, but none that answer everything I need to know. I hope there's someone out there with enough expertise to answer a few specific questions. This is what I understand (and please correct me if I'm wrong): 1. Hardware limitation is 3GB total. (4GB for the Core 2 Duos) 2. Slots support 512MB & 1GB SODIMMs (& 2GB for the Core 2 Duos) 3. Slots need to have matching RAM to take advantage of dual channels (increased access speed) 4. Operating system will only see 3GB (for both Core 1 and 2?) This begs the questions: - How much of a difference do the dual channels make? The Apple store gives you the option to buy your MBP with 3GB installed, but I take it that this configuration is slower than the 2GB. Does the increased performance of that extra 1GB make up for that lost throughput of the dual channel feature? It would seem like pretty useless technology that the hardware supports 4GB of storage, yet realistically you can only use HALF of it to it's full extent. Why aren't the 2GB modules available from the Apple store? What if you installed 2x2GB? Would you then be able to use 3GB of it AND have the dual channel access? Will future versions of MacOS be able to use ALL 4GB? Also, Apple wants too much $$$ for their RAM. Is 3rd party RAM worth getting? Thanks! Joe Macbook Pro 15" 2.16 GHz Core Duo Mac OS X (10.4.8)
