Windows Error “Serious disk error writing to disk”

Hard drive is an important component of a computer system that stores data and install application and system software. Every hard drive comes with different storage capacity and data access speed. Although hard drive is a reliable storage media but in some situations, you might encounter critical errors while reading or write data from/to a Windows hard drive.

It renders all of your valuable Windows hard drive partitions inaccessible and cause critical partition loss situations. At this point, you are required to go for Partition Recovery solutions to retrieve lost, missing or inaccessible partitions and stored data. In a practical scenario, when you try to perform any operation on a Windows hard drive, you might come across the below given error message:

“Serious disk errors writing to drive X”

Here X denotes to particular hard drive partition on which you are performing any operation. In such circumstances, you need to find out the cause of data loss and go for appropriate Partition Recovery methods to get your valuable data back.Such kind of error message indicates that the hard drive is having some sort of logical corruption. These errors generally occur when you attempt to access a hard drive, which is corrupted.

The corruption could occur due to file system damage, system metadata structure corruption, disk structure corruption or virus infection.In Microsoft Windows operating system, you can easily handle hard drive corruption with the help of Chkdsk. It is an inbuilt disk repair utility that is helpful in detecting and repairing hard drive errors.

If your system can not boot up, you can use Chkdsk from Emergency Startup Disk. However, this tool is helpful in some situations, but it does not work in critical cases like severe file system corruption and disk metadata structure corruption.

you need to go a recommended Partition Recovery Software to ensure absolute recovery. These applications use high-end scanning algorithms to scan the hard drive, locate the lost partitions and recover them. Before selecting a Partition Recovery Software, you should make sure that it recovers data from the file system that you are using. These tools have interactive, simple and graphical user interface and thus allow you to have easy and quick recovery

Deleted FAT32 and NTFS Dymanic Disk Recovery

When you initialize a disk for dynamic storage, it is denoted as dynamic disk. Such disks might contain dynamic volumes like striped volumes, spanned volumes, mirrored volumes, simple volumes and RAID-5 volumes. But when you delete any of these volumes (except RAID-5 and dynamic mirrored volume) accidentally using Disk management snap-in, you can recover it and its data unless you haven’t formatted the acquired space.

If you have formatted the disk to FAT32 or NTFS, Windows lets you to recover such deleted volumes by restoring backup boot sector. However, if you have formatted it after deleting the dynamic volume, you should opt to use data recovery applications.

NTFS and FAT32 volumes keep a backup copy of their boot sectors. When you delete a dynamic volume, Disk Management erases the volume’s primary boot sector, located at sector 0 of the volume. It then deletes the corresponding volume entry from its private region database, though the backup boot sector and the original data remains intact. Thus, you can restore the deleted boot sector from its backup and hence the deleted FAT32 or NTFS dynamic volume. Since FAT16 doesn’t maintain backup boot sector, you cannot recover the volume if deleted.

Before performing these steps, make sure that you haven’t created a new volume in its place. However, you need to follow these steps to recover the deleted dynamic volume:You need to first recreate a volume of exactly same size as of deleted one. Ensure that you don’t format the volume.

Use Dskprobe.exe that allows you to restore backup boot sector. In NTFS, it is located at the end of volume, whereas in FAT32 it is place at sector-6 of volume.

Quit Dskprobe after it rewrites FAT32 or NTFS boot sector

To mount the volume for use, you should click Rescan Disks on Action menu of Disk Management

The above measures of recovering deleted dynamic volume are applicable only when you haven’t formatted it. If you have recreated a new volume, restoring the backup boot sector will not help. To restore formatted volumes, you should use Partition Recovery software. These are commercially recover partition utilities that employ safe scanning algorithms to locate and restore missing information from logically crashed disks.

Windows Data Recovery is the most powerful tool that provides complete recovery from FAT32, vFAT, NTFS and NTFS5 file system drives. It is a non-destructive Partition Recovery Software with rich graphical interface. The application supports Windows 7 RC1, Vista, XP, 2003 and 2000. It offers advanced features like RAW File Recovery, Disk Imaging, Disk Cloning, Drive Status etc

When Disk Corruption occurs on Cluster Disks

Microsoft Windows 2000 operating systems support relatively advanced clustering service. when compared to its earlier Windows versions supporting the same service. Using cluster service allows you to connect to multiple servers that are a part of server clusters and hence you can easily manage the data and programs operating within the particular cluster. In such clusters, the individual computers are termed as nodes.

Resources of these clusters could be physical components like hard disk, network cards etc. and also the logical components like applications, databases etc. At times, you observe file system corruption on shared cluster disk, specifically when the disk contains a non-NTFS partition. This might lead you to delete such partitions and restore lost data from backup. However, the unavailability of valid data backup calls for using powerful recovery applications.

You might receive the below error messages with your Windows 2000 (Advanced Server and Datacenter center editions) system that is configured to use Windows Cluster service:
“The file or directory X:\$Mft is corrupt and unreadable. Please run the Chkdsk utility”
Alternatively, you might encounter the similar error with event ID 26:
“System Process - Lost Delayed-Write Data”Above stated errors signify file system corruption.

This occurs when the cluster disk is online on a single cluster node and at the same time, other nodes access the same disk. Shared cluster disk could get corrupted in such situations if contains a non-NTFS hard disk partition.

Consider these steps to resolve the above issue:

The latest service pack of Windows 2000 has a fix of this problem

You can identify a NTFS partition by ID 0x07. You can use Diskmap tool to determine the exact IDs of your disk partitions. If it is other than ID 0x07, you should delete that partition and restore lost data from backup.

However, to fix disk corruption, you should run chkdsk or reformat the disk as the last resort. If backup seems to exist in invalid state or you don’t have any backup, use Partition Recovery applications to locate and restore the missing partition or information. Such tools prove effective windows partition recovery to recover lost files, folders and partitions.

Partition Recovery Software is an advanced and the most trusted utility to recover lost data from Windows 7 RC1, Vista, XP, 2003 and 2000 based systems. This Recover Partition application employs high end scanning algorithms and provides advanced set of recovery features. It supports FAT32, VFAT, NTFS and NTFS5 file system drives.

In NTFS volume Master File Table (MFT) is a relational database that contains information about all files and folders stored in it. Corruption in MFT primarily occurs due to metadata structure damage, file system corruption, software bugs and more. Two major hazards that you might encounter after MFT corruption are unbootable hard drive partition and inaccessibility of data.

Usually backup acts as a boom to completely recover and restore your inaccessible data. However, if no backup is available or backup falls short of providing necessary information, then you need to use advanced Partition Recovery application to recover and restore your lost partition data.

Consider a practical scenario, when you receive the below error message when you attempt to boot a hard drive partition (C:\):

“C:\$MFT is corrupt and unreadable. Please run the chkdsk utility.”

The hard drive partition becomes inaccessible after the above error message appears. Furthermore, you encounter the same error message each time you attempt to boot that hard drive partition.

The root cause for the occurrence of the above error message is MFT corruption.

To resolve the above issue and access the hard drive partition data, you need to follow these steps:Use another copy of MFT to boot the hard drive (C:\) partition. The NTFS always maintains a duplicate copy of MFT on the hard drive.As suggested in the error message, use CHKDSK utility from recovery console to repair the file system. However, using this utility may result in the below error message:

“CHKDSK discovered free space marked as allocated in the master file table

(MFT) bitmap. CHKDSK discovered free space marked as allocated in the volume bitmap.
Windows found problems with the file system.

Run CHKDSK with the /F (fix) option to correct these.”

If both the above measures fail to resolve the error message, then you will need to reinstall the operating system. A fresh reinstall erases all the formally saved files and folders from the hard drive partition. In such data loss scenarios, you need to use advanced Partition Recovery tools. Such recovery applications completely and orderly recover all the lost data by incorporating high end scanning methods. These recovery tools are self-explanatory due to their highly interactive user interface.

Converting Basic Disk to Dynamic Disk in Vista Causes Issues

Microsoft has introduced a new windows Viista version which supports Dynamic Disk Volumes for its Business, Enterprise and Ultimate editions. In order to convert Basic Disk to Dynamic Disk, we can simply use ‘Convert to Dynamic Disk’ option of the disk through Disk Management. However converting back a Dynamic Disk to Basic Disk is not usual as it needs disk formatting and causes data loss from partitions.

Users report that in some cases, after converting a Windows Vista installed disk partition from Basic to Dynamic Disk Volume, certain issues are observed:Dynamic Disk Volume can’t be removed while users attempt to reinstall Windows Vista. The Delete command which appears in Where do you want to Install Windows dialog box if user reinstalls Windows, is not available anymore.

If Dynamic Disk is to be converted to Basic Disk, all volumes are need to be deleted first and Dynamic Disk is converted to Basic Disk by using Convert to Basic Disk command through Disk Management tool. But in this case, this option becomes unavailable. In order to solve these issues, users need to first backup all the data and format the volume. If Windows Vista is being reinstalled, the Setup program gives this option.

Alternatively, Diskpart.exe command can be used remove it. It can be accomplished through command prompt. Users are advised to carry out the backup process in effective manner. Backup log report must be checked and also backup must be analyzed for all required files.

if partitions lose data when no valid data backup is available, Partition Recovery applications can be used to extract lost information. partition recovery software are the safe applications to restore lost, missing and damaged partitions’ data. These software scan the affected drive to recover lost information, from Basic as well as Dynamic Disks.

The applications are usually designed as read-only and hence can safely carry out recovery. Partition Recovery software are rich in interface. So users can easily use these applications without the aid of any technical knowledge. These software offer several advanced features to ease the process.

Windows Data Recovery is the powerful and safe Partition Recovery Software. The software supports Windows Vista, Server 2003, XP and 2000. It has a rich graphical interface. It can be used with any FAT16, FAT32, VFAT, NTFS and NTFS5 based disk. The application provides various options like RAW File Recovery, Advanced Scan, Create Image, and File Filter.

Disk Partitioning Error and Partition Recovery

In a hard disk when we divide a disk into many several partitions.We use the term Disk partitioning which is the process of dividing the disk space into several slices called partitions, each set for different data storing purpose. After the process, partition table header is created. This header defines all usable blocks of the disk and partition entries specifications. The partition entries constitute partition table and header defines the size and number information of these entries.

Users may encounter different sorts of error message if this information is unavailable or corrupt:“Disk 1 (19607MB 39838c 16h 63s) appears to have partitions created using a different drive geometry (255h 63s). This serious problem can lead to data loss. No partition manipulations should be made to the disk using this product or the operating system's products.

You should back up the data on this disk, delete all partitions, create new partitions under the new drive geometry, and then restore the data using the backup”This is a specific error message when user tries to resize the partitions using third party utilities. Partition resizing is the procedure of changing existing partitioning scheme as per the changed requirements. After disk partitioning, the disk is sliced so that different partitions are allocated definite start and end cylinders.

But if this information is not correctly communicated to the system and the application due to partition table header corruption, aforementioned error message may be
encountered. Here, disk geometry refers to the disk parameters (like capacity, sectors, cylinders etc.) that the BIOS can see and handle which are entirely different from actual physical.

If system reports errors with this geometry, Partition Recovery software will be required. We need to delete all the partitions and repartition the disk after backing up all the data. After repartitioning, data can be restored back using data backup. Data backup must be checked for media integrity and status.

But if backup fails to restore required partitions, then Partition Recovery Software can retrieve those using specific scanning algorithms for the affected media. These applications are safe and offer interactive user interface. These Partition Recovery applications can be used in any case of missing or damaged partitions.

Windows Partition Recovery is the well-known product for safely recovering lost or corrupt partitions. This Partition Recovery Software supports Windows Vista, Server 2003, XP and 2000. It has a graphically rich user interface. The software can recover partitions and its data from FAT16, FAT32, VFAT, NTFS and NTFS5 file systems based disks.

Using Fixmbr Command Causes Partition Table Corruption

In wondows hard drive there is a Master Boot Record which is an essential part in hard drive when gets corrupt, fixmbr can cure it for Windows XP and Windows 2000. It is the Recovery Console command that can rewrite the entire code of MBR. In a partitioned storage device, MBR is a small code that is located at the first sector of drive and runs every time, when the system starts booting up. So corruption of MBR makes system unbootable that can be repaired using fixmbr.

The command needs device name if MBR repair is required for device other than boot device. It only supports x86 based computer systems. However in some cases, incorrect use of this command can corrupt Partition Table that ultimately requires Partition Recovery solution. Partition Table defines disk partitions. It holds partitions information like partition size and location. Each partition records 16-bytes in the table. The command use can make all partitions inaccessible and cause data loss in following situations:

If hard disk is virus infected.

If system is facing some hardware issues.

So to avoid partition loss, it is suggested to follow up few recommendations before using the command:We need to use a suitable antivirus program that can scan and remove any virus present on disk. The antivirus program used must be updated one.All the connected hardware must be checked before using the command.All data must be backed up. Data backup should be checked for status and media integrity.

It will be more beneficial to check if data backup copy contains all the files andinformation required.These are the applications required when user commits mistakes of using fixmbr on virus infected or hardware issues facing drive with no valid backup. Partition Recovery Software offer interactive interface, safe scanning algorithms use, secure data restoration and quality features to recover lost data.

The applications are known to recover lost data from missing, lost or damaged partitions. Users can simply scan the affected drive through some other drive that has installed the application. Installation of these applications on affected drive is not recommended to prevent overwriting.

Windows Partition Recovery uses the most efficient scanning algorithms to recover partitions. The product is best for Partition Recovery for FAT16, FAT32, VFAT, NTFS and NTFS based disks. It supports various advanced features. It has an interactive interface. This Partition Recovery Software can be used with Windows Vista, Server 2003, XP and 2000.
