Can data be retrieved from a power fried drive?


Forensically always, by removing the platter and putting into a drive that is good.

what I would suggest you do it to get an external USB Hard Drive enclosure, and put the HD in there. Connect the USB to the computer and pray. If it doesn't work, put a new hard drive into it and set an automatic backup every couple or days. Power Supply Units need annual maintenance. I vacuum mine once a year and take them apart and wash and lubricate the fans every 2 years. Replace the fan after 6, they are cheap enough. But fans with ball bearings. When you do the vacuuming, do the CPU fan and heat sink and also the fan and heat sink in the video card.

PSU has a thermal fuse in it, but I would buy a new one. They are cheap too.

The hard disk may be running too hot.
The desktop case inside temperature maybe too hot. Check the power supply fan/CPU fan are operating correctly. You may need additional cooling in the desktop case an additional fan near the hard disk.

I replaced the Power Supply on an emachine T1100 and labeled the connections for P1, P4 and P6 so I could put them back. The fan came on, but the computer didn't start up. I can't find a place for the...


Forgive me if my first (educated) guess may be off, but the 4-pin connector for which your can't find a connection may go to your
system disk hard drive - all Emachine towers have a HDD (hard disk drive) bootable system disk - and it needs power to allow your T1100 to boot.
The system disk (your only bootable hard drive) is hidden (a little) in a metal enclosure in the front of the tower. The T1100 has a 20GB HDD, and in the "My Computer" display, it appear as "Drive C:", and is powered by a standard 4-pin power connector.

My computer makes a highish pitched whirring noise every time it has to do something slightly difficult, typically a video or interactive things. What is it and can I fix it?


Yes, open the side cover and determine where the noise is coming from - Harddrive, fans, DVD/CD player, etc.. If it's the harddrive, start backing up your important data asap before it goes out completely. If it's a fan, power down the computer and clean the fan. If it's t DVD/CD drive, replace the drive.

Terabyte iomega hard drive, the two lights are flashing red, fan not operating, no access via My Computer.


An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

Trubleshoot Motherboard


More than 70% of all computer problems are related to cabling and connections. Ensure all cables are connected and connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Ensure microprocessor, memory modules, and adapters such as video card are inserted correctly and didn't "pop-up" due to vibration.
System has no power at all. Power light does not illuminate, fan inside the power supply does not turn on, and indicator light on keyboard does not turn on. PROBABLE CAUSE DIAGNOSIS SOLUTION
Power cable is unplugged. Visually inspect power cable. Make sure power cable is securely plugged in.
Defective power cable. Visual inspection, try another cable. Replace cable.
Power supply failure. Power cable and wall socket are OK, but system is still dead. Contact technical support
Faulty wall outlet;circuit breaker or fuse blown. Plug device into socket know to work and test. Use different socket, repair outlet, reset circuit breaker or replace fuse.



System inoperative. Keyboard lights are on, power indicator lights are lit, and hard drive is spinning. PROBABLE CAUSE DIAGNOSIS SOLUTION
Expansion card is partially dislodged from expansion slot on the motherboard. Turn off computer. Take cover off system unit.
Check all expansion cards to ensure they are securely seated in slots. Using even pressure on both ends of the expansion card, press down firmly on expansion card.
Defective floppy disk drive or tape drive. Turn system off.
Disconnect the cables from one of the floppy drives. Turn on the system, check to see if the keyboard operates normally. Repeat until you have located defective unit. Contact Technical Support.
Defective expansion card. Turn computer off.
Remove an expansion card. Make sure expansion card is secure in expansion socket.



System does not boot from hard disk drive, can be booted from floppy disk drive. PROBABLE CAUSE DIAGNOSIS SOLUTION
Connector between hard drive and system board unplugged. When attempting to run the FDISK utility described in the HARD DISK section of the manual you get a message, INVALID DRIVE SPECIFICATION. Check cable running form disk to disk controller on the board. Make sure both ends are securely plugged in; check the drive type in the Standard CMOS Setup (in your motherboard manual).
Damaged Hard Disk or Disk Controller. Format hard disk; if unable to do so, the hard disk may be defective. Contact Technical Support.
Hard Disk directory or FAT is scrambled. Run the FDISK program, format the hard drive(See HARD DRIVE section of manual). Copy your backup data back onto hard drive. Backing up the hard drive is extremely important. All Hard Disks are capable of breaking down at any time.

After install an expansion card (network card, tape drive card, etc.) the system no longer works properly. PROBABLE CAUSE DIAGNOSIS SOLUTION
No power to monitor. All or part of the system may be inoperable. The new card may work but a mouse or COM port may not work. Change the interrupt or RAM address on the new expansion card. See the documentation that came with the new card in order to change pin settings. many expansion devices come with proprietary software that will assist you in doing this.

Disk will not power down. Has vanished from my computer, but router IDs it.


Well according to LaCie's support when the power button is failing to work and the fan becoming inconsistent it is due to the power supply failing.

This is because the OS controls the power button and if it cannot boot fully because of a power problem, then functions of the drive are turned off, including the power button.

They are going to send me a new one.

Data recovery from a bad power unit


Your data on the HD is probably OK, If the PC powers up and then shuts off it usually is a heat problem. If it shuts down quickly it may be a sensor on the motherboard that detects heat and may be bad and the motherboard will need to be replaced.

If it runs for a minute or two then shuts down there is heat somewhere causing problems with the processor and the motherboard is protecting the system. Check the fans inside the PC, specifically the small one on top of the processor, then the case fans. Also check the power supply fan and see if it is working, if not the heat may be cutting the power supply's power to the PC causing the shutdown.

When powering up my computer, I get a failure. Primary hard drive 1 not found Strike the F1 to continue F2 to run the set up utility. I think the power supply fan is not working. What do I do?


your system can not detect your primary hard disk which host the operating systems,so you check the data cable to the hard drive and the power supply to the hard drive for supply
