The drives have to be of the same rev number. must be in an anti static environment, and you should have done this before.

My seagate 80Gb sata PCB got smoke and i replaced with exact model PCB. Now PCB and spindle are working perfectly but windows xp cannot detect the HARD DISK. Please help me. Thanks Venkatesh

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((motherboard to your hard drive))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error
hope this helps

Mine hitachi hard disk is 80GB SATA i cant able to install OS because it is showing error some virus found and u r not able to formate this. first when i put OS CD in drive it will install some files and...

The problem is that XPinstallation CD does not have a SATA driver, unless you have a SATA drive on adisk etc. and can install the driver when XP asks for a hard drive driver then,XP cannot detect the hard disk and therefore won't install XP. The FIX. Go into the BIOS anddisable the SATA drive (enable IDE emulation), this will make XP think it is aIDE/PATA hard disk. Then you can install XP normally. When Windows hasbeen installed then install all the device drivers (including the SATA driver),then shut down and boot up and got into the BIOS and enable the SATA drive.

Hi, I use this HD for all of my photos and that is it nothing more. Last week I used my external, all was well. Last night I tried to upload photos from my wedding over the weekend to my Mac and the...

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.

There exist commercial "data recovery" services that can try to repair your device, just long-enough to rescue and copy your files. For example, see: for a "no data - no charge" guarantee.

Hard disk problem

i suggest that you'll buy another hard disk.. repairing hard disk is a tough job.. machines had done it, it is a very difficult job if its manually repaired... your hard disk maybe damaged if your system can't detect it. Just make sure that the cables are properly place/attached.

My computer stopped detecting my hard drive

Hi, Based on your post/description: 1. Tried on 3 different computers - no go, so it's not a PC problem; 2. Tried replacing the cable - no go, so it's not an interface problem; 3. That leaves you only with the Firelite itself. An external hardrive would consist of 2 main parts, the electronic board and the hard disk itself. The board seldom (if ever) fails. Its function is to provide conversion/interface from the SATA/IDE connectors of the HD to the out USB/Firewire. The HD more often than not fails. Most external storage uses a standard HD inside the enclosure. Your possible options: a. Claim warranty/replacement; b. Replace the HD only; c. Physically remove the HD and connect it direct to a desktop either as IDE or SATA and run manufacturer's diagnostic and/or third party recovery software; d. Seek services of professional data recovery firms (if data/files are mission critical); Hope this be of some help/idea. Post back should you need further information. Good luck and kind regards.

Hi, your query, "is there a way to fix it?" if you intend to use if again normally, afraid no way; if you want to recover/retrieve important data/files, probably: 1. seal the drive in a sandwhich ziplock plastic bag, leave it in your freezer overnight, install as a secondary master in another PC, autodetect in CMOS, if detected, boot to your OS, copy whatever you can real quick, soon as it reaches ambient temp chances are it will no longer be readable again; or 2. assuming it is an electronic problem, using a torx driver remove the pcb, get hold of another hd of same brand & model, borrow the good PCB and tempo use it, again install as secondary master in another PC. if no available 2nd HD at hand, install and while in CMOS autodetect HD, feel around the PCB components and determine which heats up faster than the others, spray it with a contact cleaner, if detected continue to your OS to back it up, continue spraying to maintain lower temp; 3. assuming mechanical problem (though highly unlikely) lightly tap with a small rubber mallet (rubber coated handle of a side cutter will do) bottom of drive and install; 4. assuming an electrical connection problem, reheat the 4 power terminals at the bottom (+, gnd, gnd & +) and/or remove the pcb and check/clean contacts at the back of the PCB and its mate, 2 sets; 5. assuming you can do component level soldering and can use a VOM, check surface mounted fuses on PCB near power connector. All of the above are last resort and are not guaranteed to revive your HD. Most require that you run your unit open with possible risk to electrical shock. If you are not comfortable, it would probably be to your advantage to seek the services of a qualified service professional. Sometimes it work, sometimes not, hope it be of some help to you. Pls post again how things turn up. Good luck and kind regards.

Hard Disk Quantum QML20000LD-A

Hi, may I offer an alternative solution? You may want to try and replace the entire PCB assembly rather than repair. I would assume that the Quantum QML20000LD-A is a few years old and so many of the same brand/model would be lying around computer repair shops. Even if defective, these drives can be: 1) direct parts source; and 2) remove/use the entire board. You can even find this kind of HD from old CPUs (166-550 MHZ.) I believe you can get them relatively cheap and faster. Hope this somewhat helps. Cheers.
