枫下家园 / 电脑电信 / 请教。有在laptop上装过SSD硬盘的吗？请问能否不clone, 而是把个人文件backup后直接换上，然后装操作系统？clone 需要连接线，手头没有。看能不能越过那一步。担心的是ssd直接装上后机器启动有没有问题。 -buug(Crouching Tiger); 2014-8-30 (#8959139@0)

为什么不行呢? -soimer(soimer=soim+er); 2014-8-30 (#8959149@0)

你是说全新硬盘直接装上机器就可以启动装操作系统？直觉应该可以，但是没有做过所以想请有经验的朋友指点一下。 -buug(Crouching Tiger); 2014-8-30 (#8959158@0)

Presumably it will work. But bios may have something to do with it since the hdd is not the same now. -meisuowei(混混); 2014-8-30 (#8959164@0)
How do you clone hdd? If so you have a way to access the new hdd already. Put both hdds on same subnet, crossover cat5/6 cable, share files. Copy then you are done. -meisuowei(混混); 2014-8-30 (#8959168@0)

the new hdd comes with a cd that can clone the hdd including the os and apps, but requires a cable to connect the hdd and usb. -buug(Crouching Tiger); 2014-8-30 {146} (#8959256@0)
i am trying to find out if i can replace the hdd without cloning because that would save me the hussle of getting a cable for just a one-time use.

只要电脑能使用光驱或USB连接安装OS应该就可以啊，将启动选项改为光驱或USB口不就可以安装了么？新硬盘多数不都是这么装OS的吗？但欲装的OS要有光盘版或在外置硬盘里哦 -see1see(Isee); 2014-8-30 (#8959199@0)

谢谢回复。把？去掉就是我想要答案，呵呵。 -buug(Crouching Tiger); 2014-8-30 (#8959262@0)

Buy a USB enclosure. Put SSD in and clone the old hdd to SSD. Then replace the old hdd with SSD. Clone is by far the simplest solution than refresh install. -xbox(Game Never Over); 2014-8-31 (#8959639@0)
我装过，建议不要克隆，为什么？ -nogirl(肉饼猪); 2014-8-31 {291} (#8959746@0)
因为SSD有4K对齐问题，可以问下狗老师，克隆可能会造成4K不对齐，影响SSD性能，重装的话在安装过程中会自己做对齐。
重装还有一个好处，如果原来没用AHCI的话可以先在BIOS里面打开再安装，如果克隆的话就不行了，这个也是提高读写性能的。
当然，如果不在乎性能可以克隆，你买SSD还是在意读写速度的吧，所以重装

忘了说了，在老硬盘根目录建个文件夹，然后把要保留的东西都放在里面，方便。如果放在我的文档或者我的照片这些目录下，接USB口访问会有问题的。 -nogirl(肉饼猪); 2014-8-31 (#8959749@0)
克隆的毛病是连文件碎片也保留了（这是影响性能的主要原因，但SSD再怎么着也比传统硬盘要快些），如果是已经用过一年以上时间或查看文件碎片如果较多，还是重装比较好，碎片即便对SSD影响不算太大也会浪费宝贵的空间或增大文件损坏的风险.... -see1see(Isee); 2014-8-31 (#8960059@0)

借帖子问问能人们 -meisuowei(混混); 2014-8-31 {214} (#8960065@0)
我有个电脑上原来是 WIN 7 HOME，后来随便找个码变成了 WIN 7 ULTIMATE （因为要用 WINXP 的模拟机）。

现在整天说 WIN 7 ULTIMATE 那啥。我怎么倒回到 WIN 7 HOME 呢？重装系统太麻烦了。而且我还把 HDD 分了两个 PARTITIONS。
