Why my laptop is showing hdd temperature 52c ? i lost my 1 tb hdd because of heating(bad sectors)

Your laptop need to clean on hardware level. Plus hdd also need chanage because over the time HDD get heat up while using. Also check the processor fan because dirt in that fane also heat up pc. Check and clean processor fan, check HDD temperature using some software. Physicaly Clean dirt from Ram.
Keep in mind simple formula V=IR ohms law. More dirt more resistant. More resistant more temperature. So clean it before it's dead

check laptop randomly shdn:
software
1) renew windows system
2) clear virus
hardware
1) change adapter or battery
2) check or soldering DC lack
3) over heating, clean cpu fan dust
4) hard disk o sector issue, change HDD

The problem defined arises when there are bad sectors on the hard drive.
Please do a complete disk check by the following procedure.
1. Open my computer
2. Right click on the drive related to the 1TB HDD
3. Select properties
4. on the tools tab select the disk check option.
5, select the two option that comes on the popup window to automatically check and also for recovery of the bad sectors.
after the scan is complete do a safe removal of the device using the eject option in my computer or the safely remove option in the taskbar near the date/Time.
PS. Removing the device unsafely can cause a HDD crash and increase the number of bad sectors.

Its either some files are missing that requires your device to boot up or your HDD may have badd sectors. Hopefully its not bad sectors. Try reinstalling your Operating System. If it does the same, your HDD have bad sectors. Then try a HDD regenerator software.

You should replace the hard disk. However, saving and copying your data is more difficult than simply replacing the hard disk. I suggest taking your laptop to a local service center for replacement. If you data is not important you can simply install a new hard drive and use a restore cd to bring your laptop to where it was when you first purchased it. Continuing to use your laptop with failed sectors will only result in lost data and eventually failure to boot up properly.

I purchase my laptop parts here and have been very happy:

After i Read your Explaination,i really sure if the Problem is at your Computer POWER SUPPLY.
Change your Power Supply to Higher Watt.
i Recomended to you to Using SIMBADA Power Supply ATX.
and to Fix your HDD bad Sector,Try to use LLF (Low Level Format).
LLF will destroy all data and Partition.So after you Format using LLF,you need to make a New partition at your HDD.
LLF is Working for me to Fix Bad Sector in a So many times.

In most cases irregular sounds comming from HDD(Hard disk drive) mean reading failure. Clicking noise usually means that disk head is having trouble reading data, it could be just a small fraction of info lost if it's only a few sectors, but if the drive is unrecognized after plugging it in and clicks all the time it's most likely a complete HDD head fault. Data recovery of such faulty drive is expensive and requires special tools and knowledge.

You have got bad sectors in the hdd so try to clean the bad sectors on it by scanning it by DM it will clean the bad sectors on it

Thanks.

Sir,
Bad sector removing is difficult task to remove /find. u can't solve bad sector harddisk. first go to run and type CHKDSK and check how the disk was or % of bad sector. the chkdsk command will solve badsector automatically. if not solves better to buy a new one or using the hdd with bad sector it not a problem

bad sectors are not fixable as far as hard drives go.
you mmight find software that claims ti fix bad sectors but the claim is false as they only temporarily overwrite the sectors and unmark the bad and remark to good but the problem remains to be the sectors are bad.
The best thing to do is to replace the hard drive with a good used one or a new one.

Sorry but as a technician I know what bad sectors are and what happens when you get them.
