Technology has a funny habit of solving one problem but then highlighting another. A typical example of this is the emergence of virtual operating systems, that is an OS that runs on top of another OS. While there are many advantages to many computer users in running these configurations they all rely the humble hard disk , and as fragmentation occurs, this can lead to instability and potentially data loss.
If you are fortunate enough to have very deep pockets then you may be using SSD’s or solid state drives. These still remain expensive and are out of the reach of most users who still have to rely (although getting much faster) on the slowest and some would say the most vulnerable technology in your computer- the hard drive. Hard drive fragmentation can cause problems with virtual machines and in some cases even data loss.
Fragmentation occurs on all hard drives and is part of the way the operating system stores the data on a disk. It won’t lay it down nice and neatly in one continuous block, but will lay it wherever there is a space. One file could literally be split into many separate places on the hard disk and this is fragmentation. If you have one OS running it can be bad but if you are running virtual machines the problems is far more serious.
Fragmentation is the scourge of modern computers as most people fail to conduct even the most basic maintenance on their computers. The situation just get worse over time and some people have even been known to purchase a new system even though there is nothing wrong with the old. On servers and raid arrays fragmentation is far more serious as it slows down business applications and reduces productivity. In very bad instances data recovery is the only method of saving the data.
Each operating system will have it’s own method of dealing with file fragmentation (or not as the case may be). Whilst Mac OS X will automatically defragment a file under the size of 20mb, windows pays scant regard to how badly files are fragmented. Other systems use a variety of different methods to combat the problem.
Utilizing defragmentation tools can help to alleviate the problem but often the use of some of these tools is very invasive and will render your system virtually unusable while they are running so what other options do you have.
Use automated defragmentation routines: Dependent upon your OS you can normally, either directly in the OS itself or via third party software; schedule defrags to run at times convenient to yourself.
Use dedicated hardware for the Virtual Machines: Whilst it may appear to be a contradiction in terms, running the virtual machine from a dedicated hard disk or RAID Array is probably the most efficient method of running the machine at all. It leads to the minimum of wear on the individual hard disk devices and means that running even simultaneous defragmentation is possible.
Ensuring your systems are working in tip top condition is vital to maintaining a productive IT infrastructure. For more great computing tips visit the IT support Bury , or click here for hard drive recovery information and raid data recovery advice.
