sd卡中保存位置
If your SD card is slow to mount when you plug it into your computer, throwing up errors, or otherwise misbehaving, you can often whip it back into shape with a little careful management. Let’s take a look at how we can help a fellow reader squeeze a little life out of their SD card.
如果将SD卡插入计算机时安装缓慢，抛出错误或出现其他异常情况，则通常可以通过一点点仔细的管理将其恢复原状。 让我们看一下我们如何帮助其他读者从他们的SD卡中挤出一点生命。
Dear HTG,
尊敬的HTG，
I have an old SD card that’s, in a word, misbehaving. When I remove the card from the camera and plug it into the SD card reader on my computer it takes ages to mount. It should mount nearly instantly like all my other removable media but it can take anywhere from one to ten minutes to get detected by Windows and become accessible.
总而言之，我有一个旧的SD卡，行为异常。 当我从相机中取出卡并将其插入计算机上的SD卡读卡器时，需要花很长时间才能安装。 它应该像我所有其他可移动媒体一样几乎立即挂载，但是它可能需要一到十分钟的时间才能被Windows检测并变得可访问。
Further, I’ve noticed a few JPG images with corruption over the last month or so. No outright failures to write but a few of them have the kind of corruption where the very lower portion of the image looks like old TV scan lines.
此外，我注意到在过去一个月左右的时间内有一些JPG图像损坏。 没有彻底的写入失败，但是其中一些出现了损坏，图像的下部看上去像旧的电视扫描线。
Is there anything I can do to revive the card or is it at the end of the road? I’ve been using it for years and have probably snapped 20,000+ pictures with it, if that helps any in your assessment.
我有什么办法可以恢复这张卡，还是在路的尽头？ 我已经使用了多年，可能已经用它拍摄了20,000多张照片，如果有帮助的话。
Sincerely,
真诚的
Sick SD
病态的SD
First things first, the price of SD cards has fallen so much over the years that if you’re using this SD card for anything you’d consider remotely critical then there is very little reason not to simply replace it. The premium SD cards we use in an old DSLR of ours, for example, were originally around $50 for a 4GB card but are now less than $10 for a card of equal or better speed. If you haven’t gone SD card shopping in a while, prepare to be shocked: the current best selling SD card on Amazon is an 8GB SanDisk card for a mere $5.95. If you find you need to replace the card you won’t break the bank.
首先，多年来，SD卡的价格已下跌太多，以至于如果您将此SD卡用于任何您认为遥不可及的事情，那么没有理由不简单更换它。 例如，我们在旧DSLR中使用的高级SD卡最初是4GB卡大约50美元，而现在等速或更高速度的卡则不到10美元。 如果您有一段时间没有去SD卡购物，请准备震惊：亚马逊上目前最畅销的SD卡是8GB SanDisk卡，仅售5.95美元。 如果发现需要更换卡，则不会损坏银行。
That said there are a few things you can do to refresh an old SD card and extend its life. Let’s look at two techniques and highlight when to use them and what they accomplish.
也就是说，您可以采取一些措施来刷新旧的SD卡并延长其寿命。 让我们看一下两种技术，并重点说明何时使用它们以及它们实现了什么。
Note: Although it sounds like the culprit in your case is the SD card, don’t forget to test the card with SD card readers beside the one you regularly use. Some years ago we thought we had a string of bad luck with faulty SD cards but it turns out that our bay-mounted card reader was failing.
注意：虽然听起来您的罪魁祸首是SD卡，但不要忘了用您经常使用的SD卡读卡器对SD卡进行测试。 几年前，我们以为SD卡故障会带来一连串的倒霉，但事实证明，我们的机架式读卡器出现了故障。
可信赖的老CHKDSK (Trusty Old CHKDSK)
Most of us are guilty of not properly removing our SD cards and other removable media. When you improperly remove a storage device a “dirty bit” is set to indicate to the operating system (on future mounting) that the device was not properly removed which, in turn, causes the operating system to spend more time analyzing the media when it is plugged back in. Further, not practicing safe ejection can lead to corruption and poor performance.
我们大多数人都有罪，没有正确卸下SD卡和其他可移动媒体。 当您不正确地删除存储设备时，将设置“脏位”以指示操作系统(在将来安装时)未正确删除该设备，这又导致操作系统在存储介质时花费更多的时间来分析介质。重新插入。此外，不执行安全弹出操作可能会导致损坏和性能下降。
One way you can remedy any problems you may have introduced by unintentionally poor SD card handling practices is to run CHKDSK on the card. Next time you plug it in if Windows prompts you to scan and fix your SD card go ahead and let it take care of things. If it doesn’t prompt you and you’d like to run CHKDSK from the command line, open up the command prompt and type “chkdsk /f /r X” wherein X is the drive letter of your SD card.
解决由于无意的不良SD卡处理习惯而引起的任何问题的一种方法是在卡上运行CHKDSK。 下次在Windows提示您扫描并修复SD卡时，将其插入并继续处理。 如果它没有提示您，并且您想从命令行运行CHKDSK ，请打开命令提示符，然后键入“ chkdsk / f / r X”，其中X是SD卡的驱动器号。
While CHKDSK will typically fix many problems that crop up with a heavily used SD card (especially one that has been improperly ejected) it’s not our favorite or end-all tool for SD card revitalizing. If you need to recover files from the SD card before taking more drastic measures, CHKDSK should be for your first stop. If you’re ready to wipe it clean and tune it up though, it’s time to move onto a more thorough tool.
尽管CHKDSK通常可以解决由于使用量过多的SD卡(尤其是弹出不当的SD卡)而引起的许多问题，但它不是我们最喜欢的或最终使SD卡恢复活力的工具。 如果您需要采取进一步的措施之前从SD卡中恢复文件，则CHKDSK应该是您的第一站。 如果您准备擦拭干净并对其进行调整，那么该是使用更全面工具的时候了。
SD Formatter的全新开始 (A Fresh Start with SD Formatter)
Although a quick scan with CHKDSK will solve many issues (and it will certainly get Windows off your back with that whole scan-and-fix warning) the best way to start with a clean slate is to format your SD card. Not just any format, mind you, but a proper format. Although Windows and other operating systems include basic formatting tools that work just fine for hard drives and most removable media, SD cards can be a bit finnicky as they include additional features not found on basic storage volumes like USB flash drives.
尽管使用CHKDSK进行快速扫描可以解决许多问题(并且肯定会因整个扫描和修复警告而使Windows背弃您)，但最好的选择是格式化SD卡。 请注意，不仅是任何格式，而且是正确的格式。 尽管Windows和其他操作系统包括基本的格式化工具，这些工具对于硬盘驱动器和大多数可移动媒体都很好用，但是SD卡可能有点麻烦，因为它们包含USB闪存驱动器等基本存储卷中没有的其他功能。
If you format an SD card with the basic format tools your SD card won’t be rendered inoperable but it will function less efficiently.
如果您使用基本格式化工具来格式化SD卡，则不会使您的SD卡无法使用，但其工作效率会降低。
In order to achieve an optimum format that strictly adheres to the standards of the SD/SDHC/SDXC card conventions, we can turn to the handy SDFormatter tool provided free of charge from the SD Association (the organization that oversees global SD card standards). You can grab a copy for Windows or OSX here.
为了获得严格遵守SD / SDHC / SDXC卡惯例标准的最佳格式，我们可以使用SD协会(负责监督全球SD卡标准的组织)免费提供的便捷SDFormatter工具。 您可以在此处获取Windows或OSX的副本。
After a sweep with SDFormatter your SD card should be good as new. If you’re still having delayed mounting on your PC (and you’ve ruled out a bad SD card reader) or you continue to have corruption issues with files on the SD card, it’s probable that the card is simply at the end of its life and its time to replace it.
使用SDFormatter扫描后，您的SD卡应该是新的。 如果您仍然延迟安装在PC上(并且排除了错误的SD卡读取器)，或者SD卡上的文件仍然存在损坏问题，则很可能该卡仅在其末尾生活及其取代它的时间。
