三星S10（Android 9）免Root实现USB大容量存储及数据恢复方法咨询

Hey there! Let's break down your question about accessing your Samsung S10's internal storage via USB mass storage mode (or alternatives) without root, specifically for data recovery.

Can you mount internal storage as a virtual disk without root? #

Short answer: No, this isn't possible with native or non-root methods.

Starting with Android 4.4, Google phased out the old USB Mass Storage (UMS) mode in favor of MTP (Media Transfer Protocol) and PTP. UMS required exclusive access to the storage partition, which would block the Android system from using it while connected to a computer—something modern smartphones can't afford. Samsung's Android 9 implementation follows this standard: there's no built-in toggle to revert to UMS, and modifying storage mount behavior needs system-level permissions that you can't get without rooting your device.

Alternative methods to access internal storage for data recovery (no root) #

If you need to recover data, here are practical workarounds that don't require rooting:

• Use MTP-compatible data recovery tools
  Most popular data recovery software (like Recuva, Disk Drill, or EaseUS Data Recovery) supports MTP connections. Just connect your S10 to your computer, select "File Transfer" mode when prompted on the device, then launch the tool. It will scan your internal storage directly through MTP and let you recover deleted files.

• Leverage ADB commands (requires USB Debugging)
  If you have USB Debugging enabled on your device, you can use ADB to pull your entire internal storage to your computer first, then run recovery tools on the local files:

  1. Enable USB Debugging in Settings > Developer Options (if Developer Options is hidden, go to Settings > About Phone and tap "Build Number" 7 times to unlock it).
  2. Connect your device to the computer and allow the debug prompt on the phone.
  3. Open a command prompt/terminal on your computer and run:

     adb pull /sdcard/ C:\Your\Target\Folder\
     

  This copies all files from your internal storage to your computer. You can then use recovery software to scan the copied folder for deleted data.

• Samsung's native tools
  If you previously backed up your device with Samsung Smart Switch, you can restore your data directly via that tool. For cases without a backup, some third-party tools optimized for Samsung devices may have better MTP compatibility than generic recovery software.

• Manual file transfer (for accessible data)
  If your device is still functional and you just need to save existing files (not recover deleted ones), connect via MTP and copy-paste files directly to your computer—this is the simplest, most straightforward method.

Important note for non-functional devices #

If your S10 won't boot up, non-root methods will likely fail because MTP and ADB require the Android system to be running. In this scenario, you might need to contact a professional data recovery service (they can access the storage chip directly), but this is usually a costly option.
