Computers

Sometimes, you may accidentally delete memorable photos on your Mac, digital camera, flash drive, or anywhere else. Relax. There are chances to recover those pictures, as long as you haven't taken any more photos or written anything else to the storage. When you accidentally delete the photos, they are not erased permanently. They are still stored on your Mac or the device which they saved before. They are just not accessible or visible. As long as the pictures are not overwritten by new files, it is 100% to retrieve them back. In order to recover the lost photos successfully, please do remember these tips 1. Immediately stop using the disk or device which contains the deleted pictures. 2. DO NOT write or save any new data on the Mac disk or device. 3. Search for a reliable and read-only data recovery software. I have tried many Mac photo recovery software, freeware and shareware. And I'd recommend this Data Recovery for Mac users. This program is easy to use; even you are Mac newbie can handle with it. It can help you recovery deleted photos from Mac hard drive, external hard drive, iPhone, iPod Touch, iPad, digital camera, USB drive, Memory Stick, etc. And you can preview the photos before retrieve them, this ensure you recover all the photos. And below is a step by step guide to show you how to use the Mac Recovery Software. Step1. Download and install the Photo Recovery. Please do remember, don’t install this Photo Recovery on the same partition where you lost data for avoiding overwriting original data. Step2. There are 5 modes for device recover; I will use my Mac hard drive as example in this guide, so choose 'Lost File Recovery'. Select my Mac hard drives and click scan, the program will automatically start scan my Mac, this process will take a few minutes, you can go away and take a coffee. Step3. Once the scan is finished, this program will recover a list of files on the Mac hard drive. Choose the files you want to recover, and then click Recover to the new step. Tips. You can preview your images before recovery. Files can be sorted by name, size, created and modified date. And you can also search specific files by file name. Step4. Select a folder to store your retrieved files. It would be a good idea to select another directory which is different from the source one, in case it would eventually overwrite the source data. Done, that'ss all. It couldn't be easier to recover delete files on Mac like that. This Data recover software also work for iOS device like iPhone, iPod Touch and iPad. As I know, it's the world 1st data recovery software for iOS device. If you want to recover photos from iPhone, plug in your iPhone to Mac, launch the program, let it scan your iPhone storage, it will return the files list including songs, photos, videos, document, etc. This is really useful when you lost iTunes music library, it can help you recover the iPhone music without buy them again on iTunes store!

As we know, YouTube is a video sharing website on which users can upload and share videos with friends, family, classmates and people all over the world. Probably you're a lover of YouTube like most people and usually visit it to find some wonderful music videos of your favorite artists. I’m sure you will want to download the YouTube video to Mac for further watch or add youtube music video into iTunes. And here is a step by step guide will provide three ways to help you how to download and convert YouTube video on Mac for free. Method1. Download YouTube video with online converter website There are many online file converting website like zamzar, keepvid, mediaconverter, videotomp3, etc. and so on. They are easy to use and free, you don’t have to download and install anything to your Mac. What you need is just copy the YouTube video URL to the box, choose the format you want to convert YouTube videos to (MP4 video for iTunes), and Enter your email address, then click 'convert'. The YouTube video download link will be sent to your mailbox after the conversion. Method2. Download YouTube video with free Mac YouTube Downloader If you don’t want to expose your email address, you can use this Mac YouTube Downloader. I have tried many YouTube downloading software for Mac. They are neither now work, nor the download speed is really slow. But this one works the best, and it can even download the HD YouTube video. After you download and install this YouTube Downloader on your Mac, when you watch YouTube video with your Safari browser, there will be a Download button show up at the top left corner of the YouTube video. Then you can click the button and choose a folder to save the YouTube video. This Mac YouTube Downloader supports batch conversion, this mean you can download several YouTube videos at a time.

Go to firefox website search it and install it. When you play YouTube video with Firefox on your Mac, you will see the ‘save video’ button on the toolbar. Click it to download the YouTube video you want. The downloaded YouTube video is in FLV format, in order to add it into iTunes, you have to convert the FLV video to MP4 video. I’d recommend this Video Converter for Mac, the conversion speed is fast and the conversion quality is good. You can also use it to convert the YouTube video to mp3 songs for iPod, iPhone or any mp3/mp4 player. What you need to do is drag and drop your downloaded video into the converter, select the right output format and then click Convert to run the conversion, that’s all.

Error Loading Operating System

Here’s how to fix this error:

Today was my turn to see this (in)famous error message after Windows XP’s setup routine had finished copying the core files to the hard disk and initiated a reboot of the computer.

The Solution (I):
Go to the BIOS settings of your machine and change the translation method used to access the hard drive from the default setting “Auto” to “Large” (not LBA, not CHS!). Reboot and with some luck installation will pick up at the point where it aborted before. If it doesn’t continue with the second part of the installation, you have to start over and do a fresh install. Leave the BIOS setting at “Large” for that task!

Note: There really *are* cases where you *have* to do a fresh install after changing the BIOS setting to “Large”. However, it doesn’t hurt to first try whether XP will finish the previous install

Now the only thing I would really like to know is: Why is it, that just Microsoft’s operating systems seem to have this problem? Every Linux distribution I installed on the very same machine didn’t have any problems whatsoever with the “Auto” setting. And to be fair: nor has Windows 98

And I really wonder why it is so hard for Microsoft to post the actual fix on their support pages instead of the blah that’s written there.

The Solution (II)
As Diana found out, another cause for this problem may be that an ATA-66/100/133 drive is attached with an 40 pin cable instead of an 80 pin cable. I can’t verify this but consider it as enitrely possible for Microsoft to choke on that so I thought I’d put it up here.

Update I: On two of my test systems I was able to set the BIOS setting back to “Auto” after the installation of XP had finished. Your mileage may vary.

Update II: The system I had this problem with is a Pentium-IV 3,06 GHz with an Award BIOS 6.0 with any part of it hardly being any older than 18 months.

Update III: As I just found out some genius introduced a new way of setting the access mode in some BIOSes. Instead of allowing to set the access mode in the “STANDARD CMOS CONFIGURATION” screen, you have to use “IDE HDD AUTO DETECTION” instead. When the BIOS reports your drive there, you *don’t* press “Y” to accept but instead press “N”. You should then be able to chose whether to use “LBA” (don’t) or “LARGE” (yup) as the access mode for the particular drive.

Currently affected mainboards seem to be:

Elitegroup 651C-M
GigaByte GA-7VTXE

If you report more models with the same strange method of setting the access method, I’m going to list them here.

Computer viruses are 25 years old

The computer virus turns 25 this year! I'm guessing that "virus" doesn't include "worm," though.

The computer virus conception story begins in 1981, when a tech-savvy 9th grader named Richard Skrenta got an Apple II for Christmas. Over the following few months he began cooking up ways to trick his friends using the machine. "I had been playing jokes on schoolmates by altering copies of pirated games to self-destruct after a number of plays," Skrenta once told the tech news site Security Focus. "I'd give out a new game, they'd get hooked, but then the game would stop working with a snickering comment from me on the screen."

When his friends realized his tricky ways, they banned Skrenta from their machines. And that's when he had an epiphany: He could put his code on the school's computer, and rig it to copy itself onto floppy disks that students used on the system. Thus was born Elk Cloner, the world's first computer virus to spread in the wild. The virus didn't do much damage; it infected the Apple II's OS and copied itself to other floppies, and every so often would display a tittering message on the screen:

Elk Cloner: The program with a personality

It will get on all your disks
It will infiltrate your chips
Yes it's Cloner!

It will stick to you like glue
It will modify RAM too
Send in the Cloner!

(Thanks, Farhad!)
