A deviced called "hard drive enclosure" serves for this purpose.
I'd choose one that supports IDE and SATA, 2.5" and 3.5", USB & eSATA.
A similar device called "E驱" in China is same to device above except that
it doesn't have enclosure and uses a more robust interface. I like it better
but never saw one in USA.
It's very cheap, sometimes is FAR. IMHO it does worth the valuable BF time
for it. Better focus on more lucrative deals instead ...

来自主题: PhotoGear版 - 佛爷们: USB 2.0/3.0
有个500GB的laptop硬盘没用,就抓了个USB3.0的enclosure做了个portable的硬盘,但
问题是:
在3.0的USB口,一切正常;在USB 2.0口上有提示Unknown device,无法认识。换了电
脑试,还是同样的问题出现。Enclosure上标明向下兼容的。
咋办??

这个其实是可以walk through的,但是门槛高,我不想让小狗爬,所以把有门的那块倒

谁知道这个问题的答案?

Does the AirPort Time Capsule (2013) allow USB or Ethernet-connected drive
to be used as part of the Time Capsule functionality?
Would like to explore connecting a USB-drive-enclosure and/or an Ethernet-
drive-enclosure to allow more backup space to be available to users on my
home network. Even if this would supercede the internal drive, I would find
it preferable to other options like SLUG or FreeNAS which can be cheap... 阅读全帖

这样的(包括其他厂商),如果你买的是单独的外置硬盘(包括retail和oem),那么你
的序列号就能够查到保修。
如果你买的是其他产品里面的外置硬盘,包括enclosure,或者台式机/笔记本,那作为
最终用户是查不到保修信息的,这时的保修信息可以由提供硬盘封装(做enclosure/电

Help: External Hard Drive fell and now can not be recoganized by computer. need to recover data.
my friend's 2-month old Seagate Free Agent Desk 1.5T fell from 1-2 feet high
to carpet floor. It was sitting on top of a computer tower on the floor and
was powered on and also was (mostly likely) being used when it fell.
i took it out and did some cross test.

I have been using the hard drive as data drive in an external enclosure.
I was using windows search to find a file on this drive, then decided to
abort the search before it's completed. It did not respond well. I restarted
the computer with this drive attached (never done that before). The start
took a long time. And after that, I could not get this drive to work.
When I turn the enclosure on, it would try to read the drive, like it
normally does. Then would stop after a long try, and the window

民主的英国和欧洲国家为什么当年出现暴力剥夺农民土地的圈地运动
enclosure movement
15世纪末叶至19世纪中叶西欧新兴资产阶级和新封贵族使用暴力剥夺农民土地的过
程。这种情况在英、德、 法、荷、丹等国都曾先后出现过,而以英国的圈地运动 最为
典型。 所谓圈地,即用篱笆、栅栏、壕沟把强占的农民份地以及公有地圈占起来,变
成私有的大牧场、大农场。大批丧失土地和家园的农民成为一无所有的雇佣劳动者。这
是英国资本原始积累的最重要手段之一,海外的贸易和掠夺是另一个重要手段。
