TestDisk : A FANTASIC FREE Data Recovery Tool

I’ve been working on installing a Mac OS X 10.6 Snow Leopard on my Dell Mini 9. (also trying Dual boot) I’ve rapidly format, and change the partition of my USB-Key and also USB-HDD. And I deleted the partition table of my USB-HDD which contains lots of important data (about 200G). During the panic finding solutions, I’ve tried lots of recovery tools including some commercial softwares, but unfortunately some of them won’t work at all, some of them take hours of time and had to recover the data to an external disk (because they lack the function to reconstruct partition table).

Finally, I got TestDisk a handy command line tool.  Analysis, find the lost partition table, reconstruct — IT WORKS! — only take less than 5 minutes and recovery the entire partition.  It ROCKS, a fantastic tool 🙂

前些日子一直在尝试在DellMini 9 上面装Mac OS X Snow Leopard (另外还在尝试双启动)。因此,难免的要经常的进行格式化硬盘的操作。然后呢,一不小心,把我的一个USB移动硬盘给格式化了,分区表丢失,上面有不少的重要数据,包括一些照片,文档以及Galgame若干(该硬盘的Galgame目录曾经就不小心被我删过一次,辛苦恢复回来的)。慌乱之中找了不少恢复软件,其中还包括一些商业软件,但是,有些不是不能找到丢失的数据,就是需要非常长的扫描时间,然后还必须将数据恢复到另外一块盘上(主要是因为不支持重建分区表)

最终我找到了TestDisk,一个简单强大的命令行工具,分析,寻找丢失的分区表,找到之后直接原盘上重建分区表,整个分区就恢复了,总共不超过5分钟。TestDisk真的是一个相当优秀的数据恢复软件。

Canon unveils EOS 7D

7DIcon

As anticipated Canon has today announced the EOS 7D digital SLR. It boasts a new 18MP CMOS sensor, Dual DIGIC 4 processors, ISO range expandable to 12800, continuous shooting at 8 fps and full HD video recording. It also incorporates a new viewfinder with 1.0x magnification and 100% coverage and a 3 inch LCD with 920k dot resolution.

广大佳能用户期待已久的EOS 7D终于浮出水面。坐拥一千八百万像素CMOS,双DIGIC 4数字核心,最高扩展到12800ISO。EOS 7D的核心功能确实满足了我们的期望。凭借双DIGIC4高速核心,实现8 fps连续拍摄,以及30fps的1080p HDVido使得APS-C级别的DSLR终于拥有了全副级别的高端待遇。凭借全新设计的反光晶体,7D拥有了佳能EOS系列第一款100%可视范围的取景器,相信7D的取景器会让所有摄影师耳目一新。最后值得一提的是,7D内置了Integrated Speedlite Transmitter,也就是内置佳能Speedlite闪光灯控制器,还记得之前即使机顶不闪光也需要挂一台Server Mode的580EX的窘态么,7D将结束这种问题。

7D

总之EOS 7D绝对是弥补了佳能一直以来全副和APS-C产品线之间的一个空白,将APS-C DSLR真正带入一个高端领域。尤其适合我这种中低端用户,EOS 7D绝对是值得期待和拥有的一台相机。
