Q:

i have two CD-ROM and jumper are fixed in CD-ROMas cable select .no jumper in hard disk and computerDOESN’T work

A:

We need more info. Most important question is, are BOTH CD-ROM units IDE devices? – seems likely since you state they BOTH are set to Cable Select. But what about the hard drive – is it IDE also?
Three cases to consider:
Case 1 – HDD is SATA, both CD’s are IDE sharing ONE cable and IDE port. This configuration is OK with both CD’s set to Cable Select. There is NO way or need to set a SATA drive to Master or Slave.
Case 2 – HDD is IDE and the only device on ONE IDE port, and the two CD’s are both IDE and share a second IDE cable / port. Again, configuration OK with both CD’s set to Cable Select. Just be SURE the IDE HDD is set to be MASTER of its IDE port, and should be plugged into the END connector of its ribbon cable.
Case 3 – HDD is IDE and shares one IDE port / cable with ONE of the CD’s; the second CD is on a separate IDE port / cable. In this case the HDD REALLY should be set to Master and the CD on its cable should be set to Slave. It is certainly permissible to have BOTH the HDD and the CD set to Cable Select, but then it is IMPORTANT to plug the HDD into the cable’s END so it can be the Master, and the CD into the middle connector. The second CD on a different IDE port, also set to Cable Select, should be plugged into the END connector of its cable (if it is the only device on this port / cable) so it can be the port Master.
If you have these set properly and the machine won’t boot, first check three things in the BIOS Setup screens.
1. Make sure that the proper port for each device is Enabled. This is especially important if you have two CD’s on an IDE port and the HDD on a SATA port – you can’t boot from that SATA device unless its port is Enabled!
2. IF you have the HDD on a SATA port, check its mode – could be IDE (or PATA) Emulation, native SATA, AHCI, or RAID. If it is IDE Emulation it should be usable for booting in any Windows OS. However, if it is set to native SATA or AHCI and you’re using Windows XP of any flavor, you cannot boot from that SATA device that way unless the Win XP was originally installed with added SATA or AHCI drivers. And I’m sure you do NOT want to be in RAID mode with ONE HDD.
3. Check the Boot Priority Sequence. Make SURE it includes the HDD on whatever port it is connected to. In fact, as a step in figuring out the problem, set it to boot from the HDD first, and NO other choices, so it never even tries to use the CD-ROM drives for booting. Once it’s working you can change that to try a CD-ROM drive first before the HDD.
If your machine still will not start up, you probably have other problems, and the exact error messages on the screen will help a lot in diagnosing it.

Data recovering is a process to make available lost or damaged data that was previously available in either a hard drive or diskettes, either due to an accidental deletion or due to a disk physically damaged by shock. Data recovery was a feature accessible in older systems with MS-DOS 6 operating system.

However, the arrival of the 32 bits architecture in PC processors, and later upgraded to 64 bits, override this functionally. When data is lost, the opportunities to recover valuable or sensitive information are not lost at all. Computer data recovery software can do the job.

This type of software help people retrieve lost or inaccessible files from almost any imaginable data recovery disaster, and without the need to send your hard drive to a specialized technical service.

Computer data recovery software makes it possible for the rescue of any file more often than everybody might think. Like the old MS-Dos, modern applications not only can undelete accidentally deleted files, but also partitions, and even when power failure, software failure, or virus caused the deletion attack.

Choose the right data recovery software, which is associated with your needs. Some applications can get your files back using different utilities after the disk command, while others can retrieve the data even if the hard drive has been formatted.

System restore is another function handled by computer data recovery software. Whether logical hard drive failures or RAID reconstruction and recovery, data recovery is possible, even when your system does not recognize the drive to be rescued.

The key for you to choose the right software is by taking some time to do a search. Recognize if your data recovery problem is beyond your immediate control and even having old undelete software installed, most of the time it will not work because all of them were programmed to work in systems developed with 16 bits architecture.

Double check what every computer data recovery software offers, and be aware of those claiming to recover your files in a way outside all limits of reality, because of the saying; “if something looks too good to be true, it probably is.”

Data recovery is not a matter of a high price, in fact, sometimes smaller and cheaper or freeware programs can recover the files as well as the costly versions using mega-gigabytes. However, most of the small gems usually can make a few tasks in comparison with large, full-featured versions.

Again, make sure you do research and comparison before deciding on the best computer data recovery software to fit your needs.

So you’ve turned your head in the direction of the dreams of every technology-savvy person – the idea of converting your computer skills into cash. You want to be the local computer repair guy. It’s not like it’s anything new to you

– your uncles/nephews/parents/cousins/friends/coworkers/relatives/random people are always dumping their PC problems on your head anyway. So why not make a business our of your skills to give an excuse to charge them, and also make a little dough while you’re at it? Everybody who knows how to work with a computer inside and out, and has some spare time, has at some time or another considered this idea. To be honest, it is a great idea to make some cash, provided you are lucky, know your stuff, and are able to use your wits under stressful situations. There are people out there who make a living out of casual computer repair and sales, and also a lot of those who make significant bonuses in their part time. So why not give it a try!

What to expect

• Expect to be riddled with calls and requests for fixing computers for the rest of your natural life.
• You will get all types of customers – from friendly rich little old ladies who pay well, give you cookies and pizza, and don’t have a clue about computers, to “village customers” who will try the best to squeeze the most out of you for the least possible amount of money.
• You will get customers who blame you for the remotest computer problem they get even months after you repaired their machines. These are also usually the type of customers who refuse/delay/reduce payment on trumped up excuses. Best advice is to ditch these type of customers immediately – they don’t do well for your pocket and will give you a headache. Protect yourself with a limited warranty in your terms.
• 90% of the problems you fix will be one of these 3:
  • My computer is too slow. Please clean it up.
  • Help! I got viruses invading my PC!
  • I got blue screens or other funny error message. Fix it or please reinstall Windows.

When it comes to technology, whatever we buy today will soon be made obsolete by something faster–and in many cases, cheaper. But that’s one of the great things about our work and hobby–prices continually fall, lowering the barrier to enter into better, faster stuff.

After six years of continually falling PC component prices, falling at an average of 7.8-percent per year, according to Gartner research, 2010 will see an estimated price rise of 2.8-percent. Yes, that could mean more expensive computers.

This estimated increase is all due to the rise in memory costs, figured to be 23-percent higher this year than compared to 2009, reported the Financial Times.

Those looking to buy a new monitor, all-in-one computer, or laptop may also suffer from rising LCD costs. Analysts expect a price increase of 20-percent of flat panel displays due to shortages. Hard drives and optical drives are also in short supply.

The shortages in computer components stem from the recession, where computer makers delayed or scaled back production and investment plans. Now that things are turning around, analysts predict that the market will see a lag until supply catches up with demand.

Data is the most important inside your computer, hardware failure can be fixed by replacing parts, and applications can also be reinstalled. But data is the most value asset of your PC. There are times your hard drive will die, hard drives normally last few years, some last longer. Therefore, it’s always a good idea to backup your data before you lose them.
This tutorial is not like the pro who can recover everything of your hard drive no matter if it’s damaged or any other kind of disaster. If you hear the clicking sound of the drive, you should start to backup your data right away before it dies
If you don’t hear the noisy sounds such as whirring, clicking or buzzing, there is a good chance you can recover your hard drive. Most of the times your hard drive just missing the MBR (master boot record) or it’s damaged, and there are free utilities to fix it and can recovery your hard drive.
Just follow some of these methods to have your hard drive recovered:

1. Step 1

First thing we need to examine if the hard drive is healthy: Does it show up on BIOS? The F2 key for most brand computers will get you into BIOS settings. The BIOS will have a summary of your computer hardware info.

1. Step 2

If your computer has enough space inside, you can hook up the hard drive as a secondary drive. But if it’s your system drive, then you need to find another computer and hook it up as a secondary drive. Or you might need to buy an USB hard drive adaptor (can work on SATA, PATA or even laptop drives).

1. Step 3

Once you hook up the hard drive as a secondary drive or slave drive, boot up the PC and right click on My Computer, then choose Manage, next click on Disk Manage. It should list all the hard drive information including the formats and status. If you highlight the hard drive and can get the properties of it, most likely the hard drive is in good condition and you can browse it and copy the data to anther drive.

1. Step 4

If the drive does not show up in step 3, most likely the MBR is messed up and needed to repair. If you have the Windows XP handy, boot it up and when it loads to the Welcome to Setup screen, press R to repair a Windows XP Installation using Recovery Console. Then type in: fixmbr Read the rest of this entry »
