Здравствуйте, МИТРОФАНОВ Е.В.!
У меня была такая проблема. Но тут придется рискнуть данными. Запустите Fdisk и удалите радел. Скорее всего глюки с таблицей партишенов. Такое бывает (особенно на фат). У меня как раз тоже самое было с фатофским диском с исходниками. Помогло только удаление, но в результате получил полностью все файлы в том же виде.

Здравствуйте, МИТРОФАНОВ Е.В.!
Восстанавливать только после того (!), как сохраните на другом носителе "образ" оставшегося на диске (ищите "посекторное копирование" ...)
Далее: форматируете раздел (та же ФС и тот же размер кластера).
Восстанавливаете свои файлы на другой ЖД программой "восстаносление после форматирования".
Партишину (и, тем более Скандиску) не очень доверяйте раздел и ошибки на нем.

Здравствуйте, МИТРОФАНОВ Е.В.!

К сожалению, русского хелпа под рукой нет, а переводить лень. Касается статусов динамических дисков. На вашем компьютере ("Динамический Неподключен"):
-----------
Offline

The disk is not accessible. The disk may be corrupted or intermittently unavailable. An error icon appears on the offline disk. Only dynamic disks display the Offline status.

If the disk status is Offline and the disk‘s name changes to Missing, the disk was recently available on the system but can no longer be located or identified. The missing disk may be corrupted, powered down, or disconnected.

To bring a disk that is Offline and Missing back online

Repair any disk, controller, or cable problems and make sure that the physical disk is turned on, plugged in, and attached to the computer. Then use the Reactivate Disk command to bring the disk back online.

If the disk status remains Offline and the disk name remains Missing and you determine that the disk has a problem that cannot be repaired, you can remove the disk from the system (using the Remove Disk command). However, before you can remove the disk, you must delete all volumes (or mirrors) on the disk. You can save any mirrored volumes on the disk by removing the mirror instead of the entire volume. Deleting a volume destroys the data in the volume, so you should remove a disk only if you are absolutely certain that the disk is permanently damaged and unusable.

To bring a disk that is Offline and is still named Disk # (not Missing) back online

Use the Reactivate Disk command to bring the disk back online. If the disk status remains Offline, check the cables and disk controller, and make sure that the physical disk is healthy. Correct any problems and try to reactivate the disk again. If the disk reactivation succeeds, any volumes on the disk should automatically return to the Healthy status.

На другом компьютере (диск "Динамический Инородный"):
--------
Foreign

The disk has been moved to your computer from another Windows 2000 computer. However, the moved disk has not been set up for use on your computer. A warning icon appears on disks that display the Foreign status. Only dynamic disks display the Foreign status.

If you want to use the foreign disk and any volumes on that disk, you must add the disk to your computer‘s system configuration. To add a disk to your computer‘s system configuration, import the foreign disk (using the Import Foreign Disks command). Any existing volumes on the foreign disk become visible and accessible when you import the disk.

Note that in some cases, a disk that was previously connected to the system can display the Foreign status. For example, this can happen if all dynamic disks on the system fail and a basic disk is later upgraded to a dynamic disk. Configuration data for dynamic disks is stored on all dynamic disks, so the information about which disks are owned by the system is lost when all dynamic disks fail.
