Macbook Cannot Mount My External Hard Drive ( My solution)

leave a comment »

Key words: mac, macbook, macbook pro, cannot mount, read, recognize, find, found, external hard drive, hard disk, usb, simpleteck, redrive,

My machines: Macbook pro, 1tb simpletech redrive with external power

symptoms: cannot find the hard drive not only on desktop, but also Disk Utilities

Ways you can try:

  1. plug the hard drive’s usb to a different usb port of your Macbook. ( you have two usb ports on mac, so try both )
  2. if your hard drive need external power from AC adapter, with the usb connecting to macbook, unplug the power, and plug the power back
  3. if your hard drive use power from usb port of the computer, with usb connecting to macbook, restart your macbook.
  4. try to plug the hard drive to other mac.

It seems this kind of problem often involves with power to the hard drive. Good luck to you.

Fixed iPhone Reboot Loop after Reset Network Setting Without Restore

with 7 comments

keywords: iphone reset network setting reboot loop / stuck / won’t boot / freeze / apple logo, without restoring restore blackra120n

2010.09. 28 Update: No need to do anything, when it stucks in the apple logo, just wait. It seems the time you wait depends on how much things your iphone store. So you’d better to reset the network just before you go to bed, when you wake up in the morning, your phone should come alive. Two days ago, I waited like 40 minutes.

What I did to fix it:

  1. removed the T-Mobile sim card
  2. hold the power button to turn off iphone
  3. waited for a while
  4. turned it on, still stuck at apple logo. And after a few minutes, it was back.
  5. Wifi switch turned to grey, which means WiFi doesn’t work. Reboot iphone, and wifi works again.

I don’t know which step(s) contribute to the fix. However, my philosophy is to do something simple before something complex, which including, connecting to computer, entering DFU mode, entering restore mode and so on. Those act may change the status of your iphone and make things worse, in which case you have to restore your iphone.

Start of the problem:
iPhone can’t find wifi, I restarted it, but didn’t work. So I did the “Reset Network Settings”. And iphone tried to reboot, but stuck in the apple logo, and kept reboot.
This was the reason I had to restore my iphone last time. But obviously, I did not learn.

Here’s my iphone:
Jailbroken with redsn0w
unlocked with balckra1n
Version 3.1.2
Baseband 05.11.07
Using T-Mobile

I’m just dust

leave a comment »

Sometimes people feel unhappy because they see themselves important.

Today, when I used google earth finding accent Chinese capitals locations, I played with the mouse and zoned out to google earth’s limitation. From that altitude, earth becomes a ping-pong size ball, lonely in the universe. What about me? It’s nothing but dust.

xGPS = iphone 3G GPS + offline maps

with 9 comments

GPS is an important new function for iphone 3G. But without Internet access (Edge or 3G), it’s useless.

Many people are discussing OfflineMaps (for 1.1 or later firmware) in forums, generating maps by oneself, transferring files from computer to iphone. (I don’t know weather OfflineMaps can combine GPS with downloaded maps.) But is there some apps can save our time in doing these? Yes, xGPS can!

When your iphone is connecting to Internet, you can use xGPS to download map of a chosen area from google, and browse it , or see your real-time location on it later even without Internet access.

I tested it just now when I drove to Wendy from my dormitory. It worked well, showing my moving position on the map, just liked a professional navigation. However, when I tried to browse the map, it appeared that the map just covered very small area, even though I’d chosen downloading a large area (but just 54 M maps, ??). I think there’s still some problems in downloading specific area of maps.

xGPS can also give driving direction, which is calculated by google maps. This suggests that you can only do that when accessing internet.  

Even xGPS is not so mature, but it’s promising, and a very good GPS navigation solution for newly unlocked iphone 3G at present. It worths everyone’s try.

Add source in cydia http://cydia.xwaves.net and install xGPS.
Don’t forget to choose “iphone 3G GPS” as your GPS receiver.

Wonderful tour to Getty Center

with one comment

I payed my first visit to Getty Center yesterday. If I wasn’t too tiered to continue, I would spend another two hours there, after my nearly 6 hours exciting exploring.

This is a great place beyond my expectation. Maybe I am sort of outdated, I expected such famous museum is all about huge buildings, big gardens with European classical style. But Getty tells a different story. In my opinion, it’s better. First of all, the location of the museum is good. It is on the top of a mountain, from which you can see the whole L.A., snow topped mountains in far, and blue pacific on the other side. On the other hand, the architectures of the museum are modern and they go with natural surroundings harmoniously. In addition, from the point of functions, the museum excels in displaying collections and is convenient for visitors.

Well designed look and functions make a good work of architecture, but not enough for a museum. What makes Getty stunning are its world-classed collections and changing exhibitions. Here, I caught big names, such as Titian, Millet, Monet, Cézanne, whose works I only saw in the powerpoint in my European paintings course when I was studying undergraduate in China. This is the first time I was so closed to large amount of master pieces, and got great shocked by them.

We have great theme parks in China; we also have walk of fame in Hong Kong. But we don’t have a museum like Getty Center. The unique characters of the museum make it unparalleled in the world.

Tips: Getty Center closes at 5pm except on Saturday at 9pm. Go there on Saturday, enjoy the sunset and LA’s night scene from it.
