Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. In other words, losing saved information on your computer that has been damaged or is no longer accessible, information that is essential to you. Often the data are being salvaged from storage media such as internal or external hard disk drives, solid state drives (SSD), USB flash, storage tapes, CDs, DVDs, RAID, and other electronic infrastructure.
Some methods used to recover your data are:
When data have been physically overwritten on a hard disk it is generally assumed that the previous data are no longer possible to recover. In 1996, Peter Gutmann, a computer scientist, presented a paper that suggested overwritten data could be recovered through the use of a magnetic force microscope. In 2001, he presented another paper on a similar topic. Substantial criticism has followed, primarily dealing with the lack of any concrete examples of significant amounts of overwritten data being recovered. To guard against this type of data recovery, he and Colin Plumb designed the Guttmann method, which is used by several disk scrubbing software packages.
Corrupt file systems:
In some cases, data on a hard drive can be unreadable due to damage to the file system. In most of these cases, at least a portion of the original data can be recovered by repairing the damaged file system using specialised data recovery software. This type of data recovery can be performed by knowledgeable end-users as it requires no special physical equipment. However, more serious cases can still require expert intervention from MLK Computing technicians – Data Recovery Melbourne
The Dynamic Host Configuration Protocol (DHCP) is an automatic configuration process used on IP networks.
Computers that are connected to non-DHCP equipped IP networks must be configured before they can communicate with other computers on the network. DHCP enables a computer to be configured automatically, eliminating the need for intervention by a network administrator. It also provides a central database for keeping track of computers that have been connected to the network. This prevents two computers from accidentally being configured with the same IP address.
Without the use of DHCP, hosts may be manually configured with an IP address. Alternatively IPv6 hosts may use stateless address auto configuration to generate an IP address. IPv4 hosts may use link-local addressing to achieve limited local connectivity.
Dynamic IP vs. Static IP
Static IP addressing is for one customer on one IP address, Dynamic IP addressing assigns a different IP address each time the ISP customer logs on to their computer, but this is dependent upon the Internet Service Provider (ISP) because some ISP’s only change the IP address as they deem it necessary.
If I have Dynamic IP Addressing through my Website Host it means that I may sharing an IP Address with several other customers.
Some businesses may require static IP addressing for their internet connection for remote login, VPN connections and others, to make sure your internet connection is setup correctly to suit your needs speak to one of our technical engineers today on 03 9470 6723.
