What Is The Leading HD-DVR

The fresh HDTV technological science is stunning, and has vastly improved the appearance of our favorite Television shows and movies. But there is one nagging problem and that is that the Television shows continue to be bad. A silly sit-com will insult your intelligence in high definition just as easily as it will in standard def, if not more and this is where DVRs come in.

The DVR is the short form of digital video recorder which is also called a personal video recorder or PVR which essentially is same as a VCR, which records content from a Television program. The DVR is however capable of doing much more than the old VCR, in the sense that it makes Television viewing more crisp where you do not have to waste time viewing trash. Since it records everything that you are watching, you can choose to pause your viewing and see it later since it all recorded for your pleasure.

Regular models have been around since about 1999, but recently they have had to be adapted to handle high-def content. Driven by a hard disk drive which is larger than the one which your desktop computer carries, the HD-DVR can store high def content spanning thirty five hours and 300 hours of general content. naturally the new models have improved in other areas, too - for example the TiVo Series 3, for example, can up scale general definition content to give it better quality, and can record two channels concurrently while you watch a third.

A quick way to get a HD-DVR is to take one on hire or lease from the cable company by paying only six to ten dollars per month, but most users feel that the memory is not enough which ranges between eight to ten hours of HD content and the hardware they receive is not very comfortable to use. The most feasible resolution to this problem is to buy a TiVo Series 3 HD-DVR, which right now costs about 0 but you would be amazed at its quality of broadcast, storage storage and comfort of use.

The benefits of employing such recording devices are massive. You could program it to record any Show of special pursuit to you, even if you are unaware of its being - for instance program the TiVo to record all movies starring Morgan Freeman showing in any channel anytime. No more mindless channel-surfing, and of course, it can be used to skip over commercials, which can eliminate several hours of wasted time per week.

The affect is so great that nearly 70% of television promoters confirmed in a recent study that with DVR encroachment in the market, the 30 second spots would become defunct. This also included a comment by one fourth of admen who said that they would reduce their Television publicising budget and use it in some other avenue. When you connect your HDTV with a Blu-Ray DVD and a HD-DVR, you can finally say au revoir to the annoying Television commercial messages.

Use of Backup Tapes in Computer Forensics

The field of Computer Forensic work is very closely associated with data recovery from data storage media such as USB pens and hard disk drives. However there is a lot of information that is not stored on a data disk but is in fact stored on data tapes. In fact throughout the world the largest amount of data is stored on data tapes. Therefore is this kind of information and its storage facility any use to those in the computer forensic field?

Most of us are aware that the hard disk drive of a computer holds the most current information available as well as a variety of other forensically valuable data such as local temporary files and internet history records. So if you have the hard disk drive is there any reason to look at backup data tapes?

With computer forensic work there is often a background investigation conducted meaning that it is preferable that the less people that are involved is the choice to conduct the investigation. Where there is the ability to use data that is from a tape archive it is often a way to carry out an investigation more discretely and does not require that entire systems must be seized. When it is possible to locate data backup tapes this is an option to conduct an investigation or audit with the potential to do so without alerting those being investigated or audited.

With an audit for example the disruption spreads further than that business or person being audited and raises fear in others and being able to covertly carry out the data analysis, prior to any investigative results, reduces any stress or loss of morale of others who are not perhaps directly involved.

Data in local systems comes and goes and can often be replaced, especially where this is the intention of the business or person being investigated. Back up data information provides a snap-shot of a system or systems and therefore provides a historical record. Therefore if there is an attempt to remove information from a local system and that information was previously stored on a back up system then that information will be able to be recovered within the backup data tape.

Those who specialize in this form of investigation will work back through the backup data tapes and can therefore gain a greater insight into any system abuse or illegal behavior that may have taken place. Unless the person who is attempting to erase information has a great knowledge of the system and erasure techniques then the information that is being sought, if it in fact exists, should be located within the backup infrastructure.

Those conducting the investigation of the data must have knowledge of the backup infrastructure itself. There is likely to be a significant amount of information stored within backup tapes so knowledge of how to process this information to reduce the search time requirements is a key factor. This is especially important relating to cost factors as well as man-power and time to conduct any investigation or audit.

As an example, if there are 3000 tapes that require 3 hours each to read completely and you could use 10 systems with 80% operating time this would mean the required time to read the 3000 tapes would be approximately 50 days. This does not take into account the requirement to actually analyze and organize the data itself.

In these cases a pre-scanning system for the specific type of tape and system is required to reduce the actual time for identification of the data on each of the tapes. When this is effectively carried out the time can be reduced from 3 hours per tape down to approximately 15 minutes per tape. That therefore reduces the time period from 50 days to around 4 days for the reading of the data.

The point being that while the data tapes hold the information required a suitable system must be available to sort and categorize the information to eliminate irrelevant data and only leave those investigating the tapes the information that they require to complete a more thorough analysis of the relevant facts.

There are a great many factors in computer forensic analysis and there are no standard systems that will apply to all data tapes. A great understanding of the system and where the data may be stored is generally the first step in the investigation, after retrieval of the data tapes. This information is of course beneficial to those being investigated as well as those who wish to have some investigation completed. There is a great deal of information available about the abilities of computer forensics and if this is something that interests you it is suggested you yourself “dig a little deeper” into your particular angle of computer forensics.

RAID Data Recovery Requires an Expert Specialised Service

RAID is the term for a complex method of data storage, which relies on splitting and copying information across a number of hard disks. The method was originally designed to allow users to increase their storage capacity by using several cheap disk-drives – hence the acronym RAID: Redundant Array of Inexpensive Disks – but has developed to mean any multiple-drive storage system.

As such systems are designed to maximise the reliability of data storage and increase the capacity for input/output, a crash can be very serious due to the storage system’s very complexity. A good RAID data recovery service treats problems with these types of systems as a top priority.

Some of the problems encountered during the operation of RAID systems include the failure of the array or the controller card, corruption during the card’s set-up, a refusal to boot or multiple hard disk drive failure.

The initial professional diagnosis of a problem with a RAID system takes place in a laboratory environment. Here, the technician examines the disks to see if they are immediately accessible using specialised equipment. If the system is accessible, the technician copies all the data on to a new disk, leaving the original disks open to a full and safe analysis, and hopefully leading to full RAID data recovery.

If Your Computer Needs Help Fast Use the XP Recovery Tool THE PROBLEM

Life can be wonderful if your computer is working well and it can be a torment if it's not. There can be all sorts of problems but some are really disasters

One of the following events indicates that your computer needs major repair.

- your computer won't boot

- BSODs (blue screen of death) keep coming up or come up at the worst time

- you have a major virus infestation that is crippling your computer

- computer performance is the pits and/or you get all sorts of weird errors

ANALYZE THE PROBLEM

The first thing you need to do is to check if the problem is due to hardware failures.

If you are experiencing BSODs, Techmetica's BSOD list will tell you which ones are due to hardware problems. They suggest what to do to repair the particular hardware problem.

If a hard disk problem seems likely, you can use the UBCD (ultimate boot CD) available at UltimateBootCD to diagnose your hard drive and possibly fix it.

SOFTWARE REPAIR YOU MIGHT CONSIDER

You can try to do a repair install which will use your XP installation CD to repair your problem. If successful, it will leave your programs and data intact.

This method is somewhat complicated and techy and not for the faint of heart. The best write up on this is provided by Michael Stevens Tech

You might also try an 8 step repair from a Geek squad veteran found at the Icrontic site.

AN AUTOMATIC METHOD

There is software available that will automatically repair your computer and can do this even if you can't boot. It will cost you a small amount of money but it is much less than what a repair shop would charge and it will save you hours of time. This approach makes the most sense for the majority of computer users.

10 Simple Ways To Speed Up Your Windows XP

1. Defrag Disk to Speed Up Access to Data

One of the factors that slow the performance of the computer is disk fragmentation. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. To speed up the response time, you should monthly run Disk Defragmenter, a Windows utility that defrags and consolidates fragmented files for quicker computer response.

* Follow Start > All Programs > Accessories > System Tools > Disk Defragmenter

* Click the drives you want to defrag and click Analyze

* Click Defragment

2. Detect and Repair Disk Errors

Over time, your hard disk develops bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing difficult or even impossible. To detect and repair disk errors, Windows has a built-in tool called the Error Checking utility. It’ll search the hard disk for bad sectors and system errors and repair them for faster performance.

* Follow Start > My Computer

* In My Computer right-click the hard disk you want to scan and click Properties

* Click the Tools tab

* Click Check Now

* Select the Scan for and attempt recovery of bad sectors check box

* Click Start

3. Disable Indexing Services

Indexing Services is a little application that uses a lot of CPU. By indexing and updating lists of all the files on the computer, it helps you to do a search for something faster as it scans the index list. But if you know where your files are, you can disable this system service. It won’t do any harm to you machine, whether you search often or not very often.

* Go to Start

* Click Settings

* Click Control Panel

* Double-click Add/Remove Programs

* Click the Add/Remove Window Components

* Uncheck the Indexing services

* Click Next

4. Optimize Display Settings

Windows XP is a looker. But it costs you system resources that are used to display all the visual items and effects. Windows looks fine if you disable most of the settings and leave the following:

* Show shadows under menus

* Show shadows under mouse pointer

* Show translucent selection rectangle

* Use drop shadows for icons labels on the desktop

* Use visual styles on windows and buttons

5. Speedup Folder Browsing

You may have noticed that everytime you open My Computer to browse folders that there is a little delay. This is because Windows XP automatically searches for network files and printers everytime you open Windows Explorer. To fix this and to increase browsing speed, you can disable the “Automatically search for network folders and printers” option.

6. Disable Performance Counters

Windows XP has a performance monitor utility which monitors several areas of your PC’s performance. These utilities take up system resources so disabling is a good idea.

* Download and install the Extensible Performance Counter List ( http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/exctrlst-o.asp )

* Then select each counter in turn in the ‘Extensible performance counters’ window and clear the ‘performance counters enabled’ checkbox at the bottom button below

7. Optimize Your Pagefile

You can optimize your pagefile. Setting a fixed size to your pagefile saves the operating system from the need to resize the pagefile.

* Right click on My Computer and select Properties

* Select the Advanced tab

* Under Performance choose the Settings button

* Select the Advanced tab again and under Virtual Memory select Change

* Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory. If you have less than 512MB of memory, leave the page file at its default size. If you have 512MB or more, change the ratio to 1:1 page file size to physical memory size.

8. Remove Fonts for Speed

Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.

* Open Control Panel

* Open Fonts folder

* Move fonts you don’t need to a temporary directory (e.g. C:\FONTBKUP?) just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.

9. Use a Flash Memory to Boost Performance

To improve performance, you need to install additional RAM memory. It’ll let you boot your OS much quicker and run many applications and access data quicker. There is no easiest and more technically elegant way to do it than use eBoostr ( http://www.eboostr.com ).

eBoostr is a little program that lets you improve a performance of any computer, powered by Windows XP in much the same way as Vista’s ReadyBoost. With eBoostr, if you have a flash drive, such as a USB flash thumb drive or an SD card, you can use it to make your computer run better. Simply plug in a flash drive through a USB socket and Windows XP will use eBoostr to utilize the flash memory to improve performance.

The product shows the best results for frequently used applications and data, which becomes a great feature for people who are using office programs, graphics applications or developer tools. It’ll surely attract a special attention of laptop owners as laptop upgrade is usually more complicated and laptop hard drives are by definition slower than those of desktops.

10. Perform a Boot Defragment

There's a simple way to speed up XP startup: make your system do a boot defragment, which will put all the boot files next to one another on your hard disk. When boot files are in close proximity to one another, your system will start faster.

On most systems, boot defragment should be enabled by default, but it might not be on yours, or it might have been changed inadvertently. To make sure that boot defragment is enabled:

* Run the Registry Editor

* Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction

* Set the Enable string value to Y if it is not already set to Y.

* Exit the Registry

* Reboot
