About Cheadle DATA Recovery Ltd.
CDR – Manchester Data Recovery Services – has been trading since 2006 and offers professional data recovery services to the whole of the UK as well as providing services for those internationally. Located close to the M56 and M60 in South Manchester, we welcome customers to visit in person with their storage device. Diagnostic tests can be completed on your HDD, SSD or RAID array whilst you visit.
CDR is recognised as providing a reliable and specialist data recovery service. We provide services through a network of IT Support companies and PC Shops. Moreover, CDR also performs the more technically challenging work on behalf of several other data recovery companies.
If your RAID array or server has been declared, “unrecoverable,” by another company please contact us. In many cases we can recover the data. If data cannot be recovered there will be no charge.
Our main website hosts several years worth of articles published on data recovery and is a valuable resource for those wishing find out more.
Professional and Reliable
Diagnostic tests take place in a telephone consultation. This is free and a fixed price quotation shall be generated. We can provide you with the best chance of a successful recovery in a timescale to suit you. An emergency 12 to 72 hour service is available, which includes weekends and bank holidays. Phone CDR on 0161 408 4857.
RAID Recovery Method
CDR is a fully equipped data recovery lab. It is always necessary to work from a cloned version of a failed disk to rebuild a RAID. To achieve this the appropriate hardware disk imaging equipment is required. If required any failed mechanical components of a HDD are replaced in clean air conditions. View the equipment used.
Assurance of Success
Ahead of any payment we will always provide out file list viewing software so you may check that data has been recovered. We can also check the integrity of individual files manually (e.g. SQL database .MDF and .LDF) and provide you login details to a test computer for you to preview the data. See the software in use.
Data Recovery Prices
CDR will always provide a fixed price quotation for the data recovery on your failed RAID array or server. This quotation is provided to you in advance of receiving your failed storage device. The quotation we provided will cover all possible costs associated with the work and is only payable on successful recovery of the data you require.
Over the course of a 10 to 15 minute phone call we should be able to determine what work is required to recovery your data and then send you fixed price quotation in writing.
For more information on the cost of data recovery services, and why you should never accept a 'variable price estimate' then please see our Pricing page.
CDR - Manchester Data Recovery Services - has been successfully recovering data since 2006. Please review some of our case studies for RAID and server data recovery.
CDR recovers data from all RAID and server environments, including proprietary configurations. We regularly recover data from systems which have been declared "unrecoverable" by other companies.
CDR can provide the best possible chance of a successful recovery of your data. Moreover, we only raise an invoice for any work once we have shown that the data you require has been recovered OK.
RAID Array configurations and filesystems
- HFS and HFS+ (Apple Mac)
- Ext2, Ext3, Ext4 (Linux including soft RAID)
- UFS (Unix)
- ZFS (Sun)
- FAT, FAT32, exFAT
Typical RAID failures
RAID arrays are advertised by manufacturers as to provide a secure place to store data. Moreover, if there is a fault the system administrator should be alerted, and if the appropriate actions are taken then there should be no risk of data loss.In reality, we find that there many reasons why data loss can occur in a RAID array. These include:
- Failed RAID controller or loss of configuration data
- Multiple disk failure (2 disk failure in RAID 5, or 3 disk failure in RAID 6)
- Filesystem corruption
- Failed rebuild
- Deleted files or folders
- Formatted / initialised disk set
Frequently Asked Questions (FAQs).
Occasionally potential customers ask what is the percentage success rate is of a successful recovery. No data recovery company could provide this accurately due to the number of variables involved in complex recovery work.
Some companies makes claims of their success rates and provide ‘exact’ percentage rates, e.g. 98.2% successful. This an example of ‘spurious accuracy,’ and is a method to give the appearance of certainty by presenting false precision.
It is critical that you do not attempt to force disks back online, or perform any type of RAID rebuild. This can result in new data being written across the disk set resulting in making the original data unrecoverable.
A botched DIY data recovery is the main reason why CDR has to declare a RAID, “unrecoverable.”
CDR lets you define the parameters of success at the point of the initial quotation. In the quotation sheet you can specify what the ‘critical data required’ is. If it is possible to recover data based on this specification then it is possible to consider the recovery successful.
