My external hard disc is not detected by pc and some strange tick
Some tickling noise coming from my external hard disk and it is not detected by pc
I bought 120 GB Transcend external hard drive initially it showed up in my laptop but when I formatted and started to transfer data it got heated up and then it was not detected at all though the light still keeps on and a sound of tickling comes out of it like the old gramaphone record needle misses the track. please advise what to do ? is it repairable or has to be returned back to vendor zmanz

The ticking noise is not a good sign at all! Try plugging it into a different computer and hope that it works. You need to get the files off of it ASAP.
The tikking sound you speak of is the disks inside your hard drive hitting each other, also known as a hard drive crash. This is BAD news if it is. Your data will not be able to be recovered if it has crashed due to physical damage. Try to get your data off of it as soon as you can, that is, if you still can
Try to connect it as a master. Just connect this hdd only, so we can know if is detected in the bios. If yes then there's a possibility that you can recover your data. If you hear clicking noise/strange sounds then there's also a big chance that your hdd is broken. If it is detected in the bios, then remove it again and try using an external casing so you can put this hdd in it and connect it to your pc thru usb. I assume that your hdd is an ide and not sata since it's old as you say. Then to go to windows and see if your hdd in external casing is detected. Another option is that if it is detected in the bios, use a bootable cd with software apps for Hard disk tools like HDD Regenerator or HDAT2 to check and repair bad sectors on your hdd. Use this at your own risk and may destroy all data on your hard drive. If noe of this works, then you can assume that your HDD is not functioning anymore.
Do you have a CD disc software installer of your external hard drive (F.A. Porshe 160GB).? If you got it, you must reinstall it, so that your Imac can detect it. Otherwise, find it at the internet and download it. The power failure could have damage some stored data about your External Hard Drive in your Imac. That's why, you have to reinstall it.

the first thing that pops up in my mind is a power problem. check if the hard disk starts making a 'spinning' noise when you plug in the power chord and turn the disk on. when you hear a ticking noise instead, it means the disk is broken. be sure it only makes the spinning noise. if it does, connect the usb-cable between the disk and the computer. if the disk is not recognised, replace the cable. if still not ok, post what you did as a comment, and please be as accurate as possible, because this problem may have several causes.
This is never a good sign!! Hard drives only 'tick' when they are bad, or going bad. Some popular techniques for attempting to temporarily fix the drive include freezing it for several hours before trying again, standing the drive on it's thin edge, or lightly tapping it with a SMALL hammer or the **** end of a screwdriver as you power it on. Some have also had success (myself included) removing the controller circuit board and replacing it with the controller of an identical drive, preferably from a drive from the same lot as your broken drive. However I don't recommend this to most people, it is an advanced technique and easy to screw up! Also not likely the problem if the drive is clicking.
If you can get it to work again this way, copy your data from it IMMEDIATELY then recycle the drive and never use it again!
A final option would be to send the drive to a data recovery specialist, but be forewarned this can be VERY expensive.
I've had this problem many times with external SATA hard drive plugged into the usb. My 120gig hard drive takes significant power to operate it. On laptops with a long cable to the usb, I get the Tick tick tick sound and the light flash in concert with the ticking. On laptops with short cables to the usb, the hard drive works. On one desk top, the hard drive doesn't work on the front usb but does on the rear because the rear has no cables. The usb comes off the motherboard. Conclusion? Most likely a voltage problem from longer than usual cables from the motherboard to the usb. One solution is plug the hard drive in the rear usb. Another solution is buy a more expensive cable linking the hard drive to the usb. Or buy a shorter cable. More expensive cable may have thicker wires that won't resist the current. But I do not believe for a minute that the hard drive is faulty. I've seen it too many times and it has never been a faulty hard drive.
