Lack Of Shutdown Notification Causes Partition Loss In Windows

In the context of servers, we aspire to a better hard drive and system software performance work stations. There are several ways to achieve it. One is the use of hard disks with interfaces such as SCSI (Small Computer System Interface) over rpm (revolutions per minute), such as 15,000 rpm hard disk or caching 32 MB as a buffer. Hard disks are SCSI disks as RAID and JBOD.

As an example, a Windows server with the hard disk partition base signature, Scsiport.sys (SCSI-port driver file) sends “hwStartIo SCSI miniport SRB_FUNCTION_SHUTDOWN event for each partition. It allows to mini-driver for the shutdown process.

For a dynamic disk partition signatures expected “hwStartIo SRB_FUNCTION_SHUTDOWN event does not occur for all dynamic volumes if the” Data PORT_CONFIGURATION_INFORMATION cache = true ‘was.

It follows that, as the loss of data. If you have a caching controller, based on the specifications explain that Microsoft be informed before the arrest event. You can, after the above command, for working conditions of the internal cache memory or other operations.

CAUSE

In the case of RAID (Redundant Array of Independent Disks), it is possible that the lost data and sometimes situations of loss of scores by one or more of the following reasons:

RAID is based on the decision IRP (I / O Request Packet) to offset write-back-cache, which is allowed on the hard disk. If the cache-Quinte-command on the partition, just colors and controller cache memory results in data loss.

The operating system sends the flush cache command, even after the IRP stop ‘clears the memory cache controller. In this scenario, data loss can occur as data is written in May last Flush cache lost.

If you have enabled write-back-cache on the wrong partition and shutdown occurs, the file may be damaged, and you lose all the Windows partitions and data from them.

Partition of the loss and loss of data, situations that can not be accepted by each computer user with data and therefore they must be repaired. These situations are, in general, with tools for recovery partition.

Partition Recovery tools are third-party software, specifically tailored to your needs recovery partition. Partition Recovery Software come with interactive user interface and detailed documentation. A normal user at home, they can easily, as they will not be held before and a good technical knowledge.
