When hard drive is partitioned in Microsoft Windows using the Master Boot Record (MBR) partitioning scheme, MBR Records store primary partition entries in the Partition Table. The number of partitions available on the Hard Drive does not matter as MBR can store descriptors for only 4 primary partitions. All extra Windows partitions created on the system are reckoned as the secondary partitions and their descriptors are stored in the linked list that starts from MBR. Unfortunately, in certain situations because of particular issues with this kind of partitioning scheme, all of the hard drive partitions might turn inaccessible and consequently you might lose the partition.
In order to sort out this issue, you need to perform windows partition recovery using appropriate recovery software. Dynamic disks in Microsoft Windows supports a very few of disk partition types some of which are OEM (Original Equipment Manufacturer) partition, type 0x42 partitions for dynamic disk and extended partitions. Additionally, when MBR is damaged, even the basic Windows disk might be reported as a corrupt dynamic disk. Such troubles usually arise in Microsoft Windows 2003 and 2000.
MBR might contain some invalid partition type because of wrong hard drive partitioning tool. In such cases, conversion of dynamic disk to basic disk gets failed. You can easily convert the disk by using Diskpart.exe. However, after rescanning it, hard drive again appears as Dynamic unreadable. However, make sure that the entire data in the drive is backed up before you decide to actually follow any disk conversion process. The process comprises of step that prompts you to remove data and therefore backup is always required. If you fail on creating a backup or if the backup gets corrupt, you would have to perform windows partition recovery.
When MBR or EBR gets damaged or face corruption, the presence of hexadecimal 0x42 values in any of them enables operating system to consider it as dynamic disk even if the disk is not dynamic.
To sort out this problem, you need to first ensure that this is the case of invalid system identification of system. If this is not the case, then the problem could be due to the damaged data structure that requires windows partition recovery tool to resolve the problem and recovery lost data.
Windows partition recovery software has been programmed to scan the affected hard drive and retrieve lost, missing and inaccessible hard drive partitions. This third party windows partition recovery software is totally safe and easy to use. Kernel for Windows Disk Recovery is a prominent software that professionally handles most of the partition loss situations. This tool is designed to recover FAT32 and NTFS file system partitions and is compatible with Windows 7, Windows Vista, Windows XP, Windows 2003, Windows 2000, Windows 98, Windows 95, and DOS operating systems.
