Have the data center/host replace the failed drive or raid and restore it from the last viable backup. if not backups exist... you really should start using a backup service or preferably 2 or 3. if there is no backup in place you could have the drive sent off to a facility that specializes in data recovery. ive always run solid backups so ive never had to use those services so i can make any recommendations. if the drive is, or if the raid is using, solid state drives there is likely no possibility of recovery because of the nature of solid state drives. some data centers provide daily or weekly snapshots as part of the service, and some dont so check with them first.
</div>


<div>
The drive is dead or almost so, replace and restore from backup
</div>


<div>
Yes besides a good backup you only have a last chance in remove the hard disk from the machine and send it to a good data recovery lab.
</div>


<div>
Is it really a Hardware RAID5 configuration behind this RAID5 called drive? How many drives are involved?
</div>


<div>
Noxcho,<br />
I dont think its a real RAID its just the label.... nowthe other hard disks are fine.<br />
there are four hard disk....<br />
How can I verify if its a raid or not ?<br />
and if not are there any chances ?<br />
Regards,
</div>

Andyalder trying your advice...<br />
we were able to access the hard disk and we are copying most of the files...very slowly.... every five min its pops up a message saying a particular file is impossible to read so we skip that file....then continue.... we are already 24 hours doing this... i did not have a chance to checl the copied files yet and besides that I am calculating there is a 5% loss of the files not copied...... we will se if the copied files are in good condition...<br />
Just trying to run out of options before sending the disk to a lab.<br />
HDDscan and seatools helped us in regaining connection with the lost hard disk... it was simply not respoding... now its very slow but getting most of the files... maybe another 12 hours I GUESS.<br />
All suggestions are welcome,
</div>

Noxcho,<br />
This customer is a remote customer in charge of his own backups,,, but clearly not doing them.... problem is we do not provide this services.. just doing my extra mile for my customer... <br />
Will follow your advice and later propose our customer a good compamy for automatic backups...
</div>


<div>
Problem solved...100% recovery using different tools and techniques...<br />

Hello Experts,<br />
Our customer's server started slowing down our application. last thursday... then it started with a DAta Error (Cyclic Reduncancy<br />
it would not let us copy the files from that hard disk.... and took a lot of time to copy a few files....yesterday<br />
now today we cannot access that hard disk at all..<br />
What can we do in this case ?<br />
All other hard disks seem to be working ok. and also the server<br />

Cant access one of the hard disks on  server !!!

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Windows Server 2012

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
