Free Hard Drive Monitoring Software Acronis Drive Monitor is a free drive monitoring software that helps to protect essential data in the hard disk. By automatic checking of hard disk and episodic reporting to the user, Acronis makes data in computer more secure. Another hard disk Recovery Guide that we reviewed earlier. Acronis Drive Monitor monitors event logs and attaches flag to the occurrence that indicate that data are in danger. And when a crash of hard disk is imminent, it alerts the user about the trouble. So user can take a backup of essential data before actual disaster happens. It also explains the nature of the problem and guides the user on how to deal with the trouble.

How to use Free Hard Drive Monitoring software : Acronis Drive Monitor: Users have to only install Acronis in their computers. Once the installation procedure is complete, it starts to monitor the health of the hard disk. It gives an on-screen message to the users when a crash of hard disk is about to occur so that users can timely backup their critical data. Acronis Drive Monitor gives users extra time to respond in order to save data contained on disk devices and to arrange for their replacements.

Its services includes:
Checking for disk trouble automatically
Monitoring event logs and attaching flag to the event that indicates possibility of loss of data.
Sending an email and displaying a message on window taskbar when it uncovers a disk related problem.
Providing a weekly report showing the status of storage media.
It supports RAID drives too.

You can Download Free Acronis Drive Monitor software from here!

Apart from using Acronis Drive Monitor, make sure you also read All Causes for Data Loss. You can Recover your damage data with Free File Recovery Software.

Server RAID, NAS and SAN Information

RAID Server

RAID and other enterprise server environments have a high degree of fault tolerance however even the most well designed systems are susceptible to malfunctions and RAID systems can hardly be an exception to this rule. There’s a litany of reasons that can cause a RAID system failure. Sometimes power fluctuation, software, hardware problems (disk controller malfunctions) or even human error.

Unfortunately when a business RAID, NAS or SANs storage server system first fails, it can be the first sings an unfolding catastrophe. The damage and losses caused by such failures are not only disruptive to productivity, but the down time and outage can also often have astronomical financial consequences if not quickly remedied.

Commonly used Server RAID Configurations:
Following are RAID server makes and types, including the most widely used RAID 0, RAID 1 and RAID 5 configurations.

RAID 0

RAID O uses what is called a data striping technique. Multiple hard drives are combined into one large volume. Because it splits the data and accesses both drives in parallel, RAID O reads and writes faster than a non-RAID configuration. RAID 0 doesn’t offer data redundancy and requires a minimum of two hard drives to be totally restored as a requirement for completing a successful RAID recovery.

RAID 1

RAID 1 mirrors, or copies the content of one drive onto another twin drive. If one of your drives should fail, mirroring guarantees optimal data integrity and instant access to your data. Another advantage of RAID 1 is that it allows you to use just 50 percent of your NAS device’s available capacity. A requirement for RAID 1 is a minimum of two hard drives and when using more they must be even numbers. The advantage of this type of RAID configuration is that recovery takes less time, resources and tools – assuming that the mirrors functioning correctly when the failure occurred.

RAID 5

RAID 5 offers the best mix of data backup, capacity and performance. Although RAID 5 does stripe all available drives into a single large volume, space equal to one of its hard drives is used to store parity data. If correctly configured, when one hard drive fails, it will use the parity data to rebuild your data. RAID needs a minimum of 3 hard drives. Another backup option RAID 5 offers is hot spare. This reserves an additional hard drive that takes over immediately if another drive fails. Total RAID capacity is calculated by subtracting the space of two drives from the sum of all the hard drives. If you want to use hot spare with RAID 5, you must have a minimum of 4 hard drives.

All Disk Based RAID Array Configurations:

We address the most common RAID configurations mentioned above, but following are more obscure types available to you as well.

Server RAID Configurations:
RAID 0 RAID 1 RAID 3 RAID 4	RAID 5 RAID 1E RAID 6 RAID 5E	RAID 5EE RAID ADG RAID 0+1 RAID 10	RAID 50 RAID 51

Common RAID Failures Include:
RAID controller failure Rebuild failure Damaged striping Multiple drive failure (or multiple drives go offline) RAID array or volumes that won’t mount after a server crash	Configuration damage or corruption Addition of incompatible drives Hardware conflicts Software corruption Viruses or malicious intent

RAID Hard Drive Types:
IDE/ATA/PATA/EIDE ULTRA/ATA 100 SAS SCSI	ESDI Fibre Channel USB Firewire	PCMCIA RLL iSCSI eSATA	SATA II/2.0 SATA MFM
