There are different kind of hard disk problems you may experience. First, if Hard Disk Sentinel shows suggestions about improving the situation (for example by changing/improving the data and power cables and connections, verify power supply, improve cooling) it is recommended to do it prior any further steps.
Troubleshooting laptop hard drive failures begins with eliminating non-hard drive issues.
Many consumers and office workers have taken to referring to the body of any computer or laptop as a "hard drive". If your LCD screen won't light up, the problem almost certainly isn't related to the hard drive.Does Windows or whatever working framework you are utilizing boot? Does the workstation start up regularly, get all of you the route to the work area? On the off chance that the OS boots, except if you are managing a clamor issue, the issue you're having is either programming related or an aggregation of blunders on the drive.If you're getting very flaky errors, having difficulty when connected to the Internet, are seeing large scale file corruption or data loss, the problem is more likely due to malware (bad software such as a computer virus, spyware, trojans) than electronic or mechanical failure. However, if the operating system disk maintenance software, such as ScanDisk, is reporting errors every time you run it, if you see text messages about "write failures" or if successive surface scans report a large number of errors, your hard drive is actually failing. If you believe the hard drive is failing, back-up all of the data that can be read and replace the drive.
Will the laptop boot with AC power adapter attached?:
On the off chance that the workstation boots up with the AC control connector connected, the issue is with the battery, not the hard drive. Continue to the battery investigating flowchart. In the event that you see the hard drive execution appears to debase seriously when you are running on battery control, it implies the power the executives is killing the hard drive after excessively shy of a postponement on no action, presumably one moment or two. You can change the power the board setting to expand the close down deferral for the hard drive or to guarantee the hard drive remains spun up as long as the workstation is turned on.
Does the laptop boot if you remove all external connections?:
In the event that you have any outside gadgets connected to your scratch pad, printers, cameras, PC Cards (the substitution for PCMCIA cards), outer consoles or mice, arrange links, screens, unplug them all. In the event that the workstation is sitting in a docking station, expel it. In the event that the workstation boots when the majority of the outside associations are evacuated, the issue isn't the hard drive, it's a flawed outer gadget or flag. You can figure out which gadget is keeping the OS from booting by procedure of disposal. The issue isn't really an equipment failure, it could be the driver for that gadget is so hostile or defiled that it's slowing down the boot procedure when called to deal with it's customer.
Does the hard drive register in CMOS Setup?:
Does the laptop BIOS see that a hard drive is installed and correctly identify it? If the BIOS doesn't register the hard drive, either the hard drive has failed, the connector has failed or come undone, or you have a board level problem.Try not to considerably consider overhauling the BIOS if the hard drive doesn't appear except if it's a substitution drive and the past hard drive registered, however is being supplanted in light of the fact that it was excessively little, mistake inclined or boisterous. The first hard drive ought to dependably be perceived by the current BIOS if the equipment is in working condition and the connector hasn't come unraveled. On the off chance that re seating the hard drive settles the issue, ensure that it isn't feeling the loss of a hold down screw.
Does reseating the hard drive in the bay fix the problem?:
PC phone drives are generally associated with the workstation through a solitary long connector that conveys the two flags and power, regardless of whether parallel IDE or sequential ATA (SATA). In the event that that connector turns out to be free, if the drive moves and comes somewhat out of the connector toward one side, it will quit working.This is a rare problem because the hard drive is mounted in a little frame that is secured to the laptop body with a screw. But if the hard drive has been replaced at some point and the screw was left out, or if some hack left the entire frame out, it can happen. Else, you most likely have a certifiable equipment failure, with either the drive itself, the connector, or the primary leading body of the PC, which gave the power and controls the hard drive. The best and best way to test this is to either make a decent attempt drive in the PC or to make a decent attempt drive in another PC. Accepting you don't have an extra workstation hard drive around and you have information on the current hard drive that you'd like to recoup, the best advance is to by a modest 2.5" drive outer USB nook. USB fenced in areas are sold as either ATA (IDE) or SATA, so purchase the one that coordinates your hard drive innovation. On the off chance that the drive is great, this will enable you to control it up and read the information off on any PC with a cutting edge USB port.
Is there "No Operating System" message? :
On the off chance that the BIOS reports "OS not found" amid the boot procedure and you just introduced a fresh out of the plastic new hard drive, it just methods despite everything you need to introduce the working framework. Next check the boot arrange in the BIOS, ensure the C: is the primary boot gadget. Else, you could have an equipment failure , yet almost certainly, the working framework has been debased. While record debasement can happen for non-deadly reasons, for example, glitches amid overheating or vibration and stun, the main source is most likely PC infections or administrator blunder, composing over or erasing required framework documents. On the off chance that you have a save circle created by your infection security programming, have a go at running it, after which you can have a go at booting the OS CD/DVD (Microsoft Windows boot plates choices) and attempting a fix establishment.
