Using a Stylus With the iPhone

[Technology columnist Walter S. Mossberg answers readers' questions]

Q. I bought an iPhone and was frustrated that my fingers appear to be too large to type properly on its virtual keyboard. Is there a stylus that works with the iPhone?

A. I hadn't realized this until recently, when a friend who bought one showed it to me, but, yes, there is. The iPhone wasn't designed to operate with a stylus, and the small, thin, hard kind that one uses with, say, a Treo, doesn't work right with the iPhone. But there are some companies that sell a wider type of stylus with a soft tip that approximates a small fingertip, and is designed for the iPhone.

If you type 'iPhone stylus' into a search engine, or an online store like Amazon.com, you will see a number of inexpensive choices. One downside: the iPhone doesn't have a built-in slot for a stylus. My friend carries his, which has a clip on the end, like a pen, in his pocket.

Q. I just purchased an external hard drive for my PC that connects through a USB port to back up photos and important files in the event of a computer crash. Would this hard drive be affected if my main hard drive crashed? Should I disconnect the external drive when it's not in use?

A. The two hard disks are separate devices, and if one has a mechanical failure, it doesn't affect the other. There might be some scenarios in which a problem with the computer itself, as opposed to a breakdown of its internal hard disk, could affect the external drive. And malicious software could corrupt or erase files on the external drive. An electrical surge could also affect both drives, or fry the computer itself.

Many people can't disconnect their external drives, because they use automated backup programs, or frequently save files to the drives. If you are doing only occasional manual backups, you could disconnect the extra drive when not in use, so you'd feel more comfortable. But, for maximum peace of mind in case of an electrical surge, you should disconnect it not only from the PC, but from the electrical outlet as well, even if you are using a surge protector.

适合iPhone的手写笔

专栏作家莫博士就有关电脑和其他电子设备的常见技术问题答读者问。

问:我买了一部iPhone,但很沮丧地发现,我的手指似乎太大了,没法很好地使用手机的虚拟键盘。有没有和iPhone配套的手写笔呢?

答:我有一位朋友买了一支。在他拿给我看之前,我一直不知道有iPhone手写笔。是的,市场上确实有供iPhone用户使用的手写笔。不过,iPhone的设计并没有考虑手写笔,那些笔头纤小、质地坚硬的手写笔(比如Treo等手机配套的)并不适合iPhone。但是,有些公司提供专门为iPhone设计的的手写笔,它们的笔尖较为柔软,就像一个小小的指尖一样。

如果你在搜索引擎或亚马逊(Amazon.com)等购物网站中输入“iPhone手写笔”,就会发现有很多选择,而且价格都不高。不过,还有一个问题:iPhone没有内置的手写笔槽。我朋友的那支手写笔末端有个卡子,他把它插在口袋里,就像插钢笔那样。

问:我为自己的个人电脑买了一个外置硬盘,它可以通过USB口连接到电脑上把照片和一些重要的文件进行备份,以防电脑崩溃丢失数据。如果我的主硬盘崩溃,外置硬盘会受到影响吗?我是不是应该在不用外置硬盘的时候把它从主机上拔下来?

答:这两个硬盘是各自独立的装置,如果一个发生机械故障,不会影响另一个。在一些情况下,比如电脑本身出问题而不是内置硬盘发生故障,外置硬盘就可能会受到影响。一些恶意软件可能会毁坏或删除外置硬盘上的文件。另外,电涌也可能会同时影响内外硬盘,或者损坏电脑本身。

由于使用自动备份程序或频繁存储文件,很多人无法切断外置硬盘。如果只是偶尔进行手动备份的话,你可以在不用的时候把外置硬盘取下来,这样你可能感觉更舒服些。但是,最保险的做法是不光把它从电脑上取下来,还要断掉它的电源(即使你有电涌保护器),以防电涌带来的损坏。
