After upgrading from a basic hard drive with EISA (Extended Industry Standard Architecture) partitions to dynamic disk, the partitions may become invisible and may not be displayed in proper location. In such cases, you won’t be able to access your significant files stored on them and face critical file loss situations. File Recovery is required to sort out such problems.

When upgrade process completes, hard drive partitions aren’t displayed and can not be operated on using MMC (Microsoft Management Console) and LDM (Logical Disk Manager) Disk Management snap-in.

When the EISA partition resides on the dynamic disk, this is shifted by Disk Management to partition two and there is no drive letter associated with this partition. The partition does not appear as a general Simple volume. The only option that is accessible when you right-click the partition is Help. Other options like Explore, Delete and Format aren’t accessible.

The invisibility and improper positioning of EISA partitions in Disk Management is a side effect of the way in which LDM handles such kind of partitions.

EISA partition is generally the first partition on a physical disk. Disk Management shows this partition in its proper location when it exists on basic disk, enabling you to explore, reformat or delete it.

The partition is protected by Disk Management from getting corrupted when it resides on the dynamic disk. You can not recreate the partition using Disk Management; it can only be done using OEM (Original Equipment Manufacturer).

If you accidentally delete or recreate EISA partition on dynamic disk outside Windows, then it could result as serious file loss situations. It may also create bootup problems and make your system unbootable. If the partition is visible and you wish to delete the partition, you should first backup all the existing volumes on the dynamic disk.

To overcome these file loss situations, you should opt for efficient file recovery software. These are advanced applications that systematically scan the whole hard drive and extract all lost files from it.

The File Recovery Software have simple and interactive graphical user interface that enables you to have quick and straightforward recovery in most file loss situations. As these software have read-only nature, they always perform safe and absolute recovery.
