Windows Mobile Pocket PC (PPC) Phone smartphone device accepts an external SD memory card to expand the storage memory so that user can install large amount of applications and data especially program taken up big size of memory space such as GPS navigation device.掌上電腦付費（ PPC ）智能電話設備接受外部SD存儲卡擴展儲存記憶體，使用戶可以安裝大量的應用程序和數據尤其是計劃採取大尺寸的存儲空間，如GPS導航設備。 However, sometimes, user may found that the SD memory card that been inserted into the mobile device card slot been disappeared and no longer been detected suddenly, especially after device wakes up from suspend or sleep state, even though seconds ago the SD card is still working properly.然而，有時，用戶可能會發現， SD記憶卡插入到移動設備卡插槽已經消失，不再突然被發現，特別是在設備起床從暫停或休眠狀態，即使秒前的SD卡仍然是工作正常。

Other related symptoms that often accompany missing or disappearing SD memory card where the device treats the card as is doesn’t been inserted or existed are including the memory card does show up in File Explorer folder tree but reported as having no free space, or the data on the memory card appears to be corrupted and causing the whole device system to hang and not responding when programs, such as camera, tries to access, write or read from the card.其他相關的症狀，往往伴隨遺失或消失， SD記憶卡的裝置把卡是不會被插入或存在的包括記憶卡也出現在檔案總管文件夾樹，但報導沒有自由空間，或數據存儲卡似乎被損壞，造成整個設備系統掛起並沒有回應時，程序，如照相機，試圖訪問，寫入或讀取的信用卡。 Other peculiar symptom is no data and files are contained within directories.其他特殊症狀是沒有任何數據和文件包含在目錄中。

The problems can be fixed and resolved by simply by just ejecting the card and inserting the card into the SD slot again.該問題可以得到固定和解決的僅僅只是彈出插入卡和信用卡的SD插槽一次。 By reinserting, Windows Mobile smartphone device will able to detect and make the card visible again.通過重新插入， Windows Mobile智能手機設備將能夠探測到，使卡再次可見。 However, doing this every time the card disappeared is annoying and troublesome.然而，這樣每次卡是惱人的消失和麻煩。 On the other hand, the Windows Mobile system may assume that it’s another memory card that been inserted, in addition to the original “Storage Card”, and thus creating another folder name “Storage Card2″ to represent the what supposed to be the same “Storage Card” or “SDMMC” memory card, causing all links and shortcuts to be broken.另一方面， Windows移動系統可能會承擔，它的另一個記憶卡插入，除了原來的“存儲卡” ，從而創造另一個文件夾名稱為“存儲Card2 ”代表什麼應該是同樣的“存儲卡”或“ SDMMC ”記憶卡，造成各個環節和快捷方式被打破。

The problem is possibly caused by different chipset configuration for the SD memory card is incompatible with either the card reader in the device, or the ROM of the device.這個問題可能是造成不同的芯片組配置的SD記憶卡是不符合或者讀卡器的裝置，或光盤的設備。 It’s這是 reported報告 that the Japan-made SD card, including MicroSD or MiniSD which use Toshiba chipset (such as some models of Kingston brand) is more compatible with most Windows Mobile device, comparing with chipset used in Taiwan made memory card (eg some models of Crucial brand). ，日本製造的SD卡，其中包括迷你型的MicroSD或使用東芝芯片組（如某些型號的金士頓品牌）是更符合大多數Windows Mobile設備，與芯片組使用了在台灣記憶卡（如某些型號的關鍵品牌） 。

If upgrading the firmware OS or ROM, replacing the handset, or changing to a better quality SD memory card is not an option, here’sa workaround that may help to fix the erroneous detection issue on inserted memory card.如果固件升級操作系統或光盤，取代了手機，或改變，以更好的質量SD記憶卡是不是一種選擇，下面的替代，可以幫助修復錯誤的檢測問題上插入記憶卡。

Run Registry Editor (eg運行註冊表編輯器（如 PHM Registry Editor PHM註冊表編輯器 and和 CeRegEditor ), navigate to the following registry key, and then change the value data for the listed registry entries accordingly. ） ，瀏覽到下面的註冊表項，然後更改值數據所列出的相應註冊表項。

[ HKLM\System\StorageManager ] [ HKLM \系統\ StorageManager ]
“ PNPUnloadDelay “=dword: 8196 “ PNPUnloadDelay ” = DWORD值： 8196

[ HKLM\System\StorageManager ] [ HKLM \系統\ StorageManager ]
“ PNPWaitIODelay “=dword: 8196 “ PNPWaitIODelay ” = DWORD值： 8196

Note that the 8196 should be entered as a DECIMAL value.請注意， 8196應輸入為十進制值。 The HEXADECIMAL ( HEX ) equivalent is 0×00002004 .十六進制（十六進制）相當於是0 × 00002004 。

According to據 MSDN的MSDN , PHPUnloadDelay specifies time delay, in milliseconds, between unmounting and detaching a device which is unavailable. ， PHPUnloadDelay指定時間延遲，以毫秒為單位之間， unmounting和分離裝置而無法使用。 PHPUnloadDelay is the basis for PnPWaitIoDelay, which specifies the amount of time waited before retrying an I/O operation on an unavailable device (such as SD card), with default value of three times the value of PNPUnloadDelay. PHPUnloadDelay的基礎是PnPWaitIoDelay ，其中規定了大量的時間等待，然後重試I / O操作就無法使用設備（如SD卡） ，與預設值價值的三倍PNPUnloadDelay 。 By default, as you should see, both registry keys have lower values of 4096 or 1500, which means shorter waiting time, which possible causing Windows Mobile to think that the memory card is gone and taken out when resuming from suspend.默認情況下，你應該看到，這兩個註冊表項有較低的價值4096或1500 ，這意味著縮短輪候時間，這可能導致Windows移動認為，記憶卡消失，並採取了從恢復時暫停。

If the registry hack above doesn’t yet solving the memory card disappearance error, try to disable the sleep mode on the SD card.如果上述註冊表黑客還沒有解決記憶卡失踪的錯誤，嘗試禁用睡眠模式的SD卡。 To do so, disable and turn off the power management for the SD memory card by change the following registry key:為了做到這一點，禁用和關閉電源管理的SD記憶卡的變化以下註冊表項：

[ HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Class\SDMemory_Class ] [ HKEY_LOCAL_MACHINE \驅動程序\ SD卡\ ClientDrivers \類\ SDMemory_Class ]
“ DisablePowerManagement “=dword: 00000001 “ DisablePowerManagement ” = DWORD值： 00000001

Soft reset the PPC mobile device after changing the registry keys to check if the memory card issue gone disappear issue has been fixed.軟復位的PPC移動設備後，改變了註冊表項檢查，如果記憶卡的問題已經消失的問題已得到修復。
