苹果(Apple)希望其 iPad 能够正确替代传统笔记本电脑和台式机。它还希望其手机受到更多面向主力手机的重视。看起来， iOS 是一个苹果(Apple)有认真计划的操作系统。这就是为什么在最新最好的 iOS 版本(latest and greatest iOS version)中首次亮相的关键功能之一就是支持外部存储设备。
在过去几年的大多数Android手机上，这很容易做到。(Android)只需将驱动器连接到手机上的USB端口，它就会显示在文件管理器中。
然而，iOS 仅在第 12 版中对其文件系统进行了大修。为用户提供了对“真实”计算机所期望的系统文件夹的访问权限。这种新的驱动器支持功能是新文件管理方法的自然演变。
问题是有时将驱动器插入 iOS 设备没有任何作用。没有错误消息，根本没有说明您无法读取或写入磁盘的原因。
好消息是，导致此问题的原因数量非常少。因此，如果您没有从扩展存储冒险中获得乐趣，那么可能值得将这些可能的嫌疑人中的每一个都从列表中删除。
如何将外部硬盘驱动器连接到 iOS 设备(How To Connect An External Hard Drive To An iOS Device)
您可能已经知道这一点，首先阅读本文。不过，首先应该确认如何将驱动器连接到 iOS 设备。
如果您有使用Lightning端口的旧 iOS 设备，则需要官方Apple 相机连接套件(Apple Camera connection kit)之类的东西，它具有全尺寸USB Type-A端口。首次连接官方套件时，请确保您有互联网连接，因为它可能需要固件更新。
如果您有一台配备 USB-C 端口的较新 iOS 设备，您几乎可以使用任何移动(OTG) USB-C 适配器((OTG) USB-C adapter)将驱动器连接到设备。就这么简单。
如果一切正常，那么您应该会在 iOS 的“文件”应用程序的“位置”下看到驱动器。如果没有，请继续阅读以获得一些建议。
重启和更新(Restart & Update)
我们不妨先解决这个问题。确保您的 iOS 设备具有最新更新。某些适配器（例如Apple相机连接套件）在使用硬盘驱动器之前可能需要更新固件。
因此，在首次将适配器连接到系统时，请确保您有活动的 Internet 连接。第三方适配器可能需要手动更新，请参阅其各自的文档集以了解这是否存在问题。
重新启动您的 iOS 设备也在列表的顶部。可能不是这个，但它只需要一分钟，你不想发现仅仅重新启动就可以解决问题。
它适用于其他设备吗？(Does It Work On Other Devices?)
在对技术问题进行故障排除时，一个接一个地排除嫌疑人总是一个好主意，最简单的方法是在已知良好的设备之间交换部件。
在这种情况下，我们要确保硬盘驱动器（或闪存驱动器）实际上没有损坏。所以将它插入另一台计算机，看看它是否有效。如果驱动器在您的 iOS 机器以外的其他设备上工作，那么问题可能出在 iOS 方面。
换掉电缆(Swap Out The Cable)
电缆真的可以让你陷入困境。(Cables can really throw you for a loop.)前一分钟他们工作得很好，下一分钟他们就死了。如果驱动器似乎无法正常工作，请尝试更换电缆。它可能只是内部电线损坏或连接器损坏。
聆听死亡之声(Listen For The Click Of Death)
如果您使用的是机械驱动器，并且在开机时会发出很大的咔嗒声(makes a loud clicking noise)，我们有一些坏消息。这是机械驱动器已死或将死的经典迹象之一。在这种情况下，它不是您的 iOS 设备。驱动器正在告别。如果它仍然有效，请尝试备份您可以备份的内容。
驱动器格式正确吗？(Is The Drive The Right Format?)
硬盘驱动器和闪存驱动器需要先格式化(drives need to be formatted)才能使用。格式化是根据系统安排驱动器内空间的过程。这就像根据杜威十进制系统(Dewey Decimal System)排列的图书馆中的书籍。除了，没有通用文件格式之类的东西。如果您的驱动器是根据 iOS 不支持的标准格式化的，您根本不会看到驱动器弹出！
您的外部硬盘驱动器可能已格式化为Windows友好的NTFS格式。要在 iOS 设备上使用它，您需要更改它。exFAT 是一个很好的替代方案，iOS 和Windows都可以轻松理解，同时保留对大文件大小的支持。
然而，有两个坏消息。首先，iOS 本身无法重新格式化硬盘。因此，您需要找到一台可以将驱动器重新格式化为 exFAT 的计算机。
其次，如果您在该驱动器上有任何数据，格式化将删除它！因此，要么与之和平相处，要么找到一个可以将其全部备份的地方，然后在格式化后将其移回驱动器。
它有足够的力量吗？(Does It Have Enough Power?)
一些硬盘驱动器需要的电量比普通的 iOS 设备所能提供的更多。他们甚至可能需要一根带有两个插头的USB电缆来提供额外的电源，尽管如今这种情况很少见。如果驱动器可在其他设备上运行，但不适用于您的 iOS 设备，请尝试使用电源并非直接来自您的设备的有源集线器。
没有更多的艰难时期(No More Hard Times)
希望(Hopefully)Apple会在未来的 iOS 版本中添加更强大的硬盘实用程序。拥有外部硬盘驱动器支持等大型计算机功能非常棒，但是当一切都出错时没有明显的方法来解决问题有点令人沮丧。
但是，有了这些故障排除技巧，您应该很快就可以开始了。
Hard Drive Not Showing On iOS 13? Here’s How To Fix It
Apple wants its iPads to be proper replacemеnts for traditional lаptops and desktops. It also wants itѕ phоnes to bе taken seriously against more workhorse-orіеnted phones. iOS is an operating system that Apрle haѕ serious plans for, it seems. This is why one of the key features to debut in thе latest and greatest iOS version is support for external storage devices.
On most Android phones of the past few years, this has been pretty easy to do. Simply connect a drive to the USB port on the phone and it shows up in the file manager.
However, iOS only received an overhaul of its file system with version 12. Giving users the sort of access to the folders of the system that one would expect of a “real” computer. This new drive support feature then is the natural evolution of the new file management approach.
The problem is that sometimes plugging a drive into an iOS device does nothing. No error messages, no indication at all as to why you can’t read or write to the disk.
The good news is that the number of causes for this issue makes up a pretty short list. So if you’re getting no joy from your expanded storage adventures, it might be worth crossing each of these likely suspects off the list.
How To Connect An External Hard Drive To An iOS Device
You probably already know this, having come to this article in the first place. Still, it’s worth confirming how you should connect your drive to your iOS device in the first place.
If you have an older iOS device that uses the Lightning port, you’ll need something like the official Apple Camera connection kit, which features a full-sized USB Type-A port. Be sure that you have an internet connection the first time you connect the official kit, since it may need a firmware update.
If you have one of the newer iOS devices that features a USB-C port, you can use just about any on-the-go (OTG) USB-C adapter to connect your drive to the device. It’s as simple as that.
If things work correctly, then you should see the drive show up under “locations” in the “Files” application in iOS. If not, then read on for some advice.
Restart & Update
We may as well get this out of the way first. Make sure your iOS device has the latest update. Some adapters, such as the Apple camera connection kit, may need a firmware update before working with your hard drive.
So make sure you have an active internet connection when first connecting an adapter to your system. Third-party adapters may need manual updating, refer to their respective documentation sets to find out if this is an issue or not.
Restarting your iOS device is also at the top of the list. It probably isn’t this, but it only takes a minute and you’d hate to find out that a mere restart would have fixed the issue.
Does It Work On Other Devices?
It’s always a good idea to eliminate suspects one-by-one when troubleshooting a technological problem and the easiest way to do that is to swap parts between known good devices.
In this case, we want to make sure that the hard drive (or flash drive) isn’t actually busted. So plug it into another computer and see if it works. If the drive works on something other than your iOS machine, then the problem is probably on the iOS side of things.
Swap Out The Cable
Cables can really throw you for a loop. One minute they are working just fine, the next minute they’re dead. Try changing out the cable if the drive doesn’t seem to be working in general. It could simply be a broken internal wire or a busted connector.
Listen For The Click Of Death
If you are using a mechanical drive and it makes a loud clicking noise when powering on, we’ve got some bad news. That’s one of the classic signs that a mechanical drive is dead or dying. In this case, it’s not your iOS device. The drive is going bye-bye. If it still sort of works, try to back up what you can.
Is The Drive The Right Format?
Hard drives and flash drives need to be formatted before you can use them. Formatting is the process of arranging the space within the drive according to a system. It’s like books in a library arranged according to the Dewey Decimal System. Except, there’s no such thing as a universal file format. If your drive is formatted according to a standard that iOS doesn’t support, you won’t see the drive pop up at all!
Your external hard drive is likely to be formatted in the Windows-friendly NTFS format. To use it with an iOS device you’ll need to change that. exFAT is a good alternative that both iOS and Windows can understand without hassle while retaining support for large file sizes.
There are two pieces of bad news, however. Firstly, iOS itself provides no way to reformat hard drives. So you’ll need to find a computer that can reformat the drive to exFAT.
Secondly, if you have any data on that drive, formatting will erase it! So either make peace with that or find a place where you can back it all up and then move it back to the drive after formatting it.
Does It Have Enough Power?
Some hard drives need more power than a humble iOS device can provide. They might even need a USB cable with two plugs for additional power, although that is rare these days. If the drive works on other devices, but not your iOS device, try using a powered hub where the power doesn’t come directly from your device.
No More Hard Times
Hopefully, Apple will add more robust hard drive utilities to future versions of iOS. It’s great to have big-boy computer features such as external hard drive support, but a little frustrating to have no obvious way to fix things when it all goes wrong.
With these troubleshooting tips, however, you should be good to go in no time.
