so here is the story :

i had a WD blue 1 TB which i store all my movies and games until it begins to fill up

 

so i decided to purchase additional HDD same type blue 1 TB and bought a cheap sata cable and power cable

 

after installing the new hdd everything was good and did a quick format and stored some files in it

 

Suddenly a hard freeze happened .... no( ctr; alt delete ) or ( alt f4 ) or ( alt tab ) solved any thing

 

the freeze lasted up to 10 mins  and the system worked again

it happens every time i start my pc

 

why does this happen ?

i checked the new hdd for errors but it was clean

may be the sata cable ??

may be the power cable ?

i need advice please 

 

thanks

I'm not clear on your mention of bad sectors when you say you checked the new HDD for errors and it was clean. A faulty SATA cable could possibly cause blocks with CRC errors, which are not genuine bad sectors but the CRC check can't tell the difference. They will however show up for example with chkdsk, unless the drive's internal maintenance had already mapped them out.

 

Are you able to reproduce the locking up consistently with the drive connected up, and never when it is not connected? If having the drive present is clearly the sole cause of the lockup, I'd think more likely the drive itself is faulty, but the only way to be quite sure would be to get to try alternative cables. I assume the power cable you mention is something like a Molex to SATA adapter cable - I don't expect there's any reason this could cause lockups.

thanks for response

update : i removed the new HDD and guess what ?? same problem happened again

it was the old HDD... i did chkdsk r , there was a bad block and restarted the pc and its good for now

but why did this happen when i installed the new HDD ?

may be the bad sata cable of the new HDD cause a bad sector in the old HDD ? 

should i install the new hdd again ? i am afraid

The SATA cable of the new drive has no physical connection to the original one, there's no mechanism for it to affect it. I expect it is probably just a coincidence.

 

I'd suggest download the Data Lifeguard diagnostic from Western Digital and run a check on the drive:

On the Downloads tab, click on Data Lifeguard Diagnostic for Windows
