Slow internal hard disk

[Steven_3020]

Hello,

My system contains 3 disk:

1 SSD wich contains my OS (Windows 8)
2 HDD's wich contain my data

Both HDD are 2TB green Western Digital drives (WD20EADS-00R6B0) they are the same age (4 years).

Now my problem is that 1 of those HDD's is extremly slow, i already did some tests using HD Tune

What do you guys think that my problem could be? And what possible solutions there could be to solve my problem?

Results of HD Tune:

The drive in question seems to be ok. Try to run CHKDSK from CMD, if there is a file system error, it would correct it.

Or try to format the drive and create fresh partitions. See how it perform.

did you try the wd data lifeguard diagnostic on the short and long test to see what happens .

I don't have an answer, but there is a very similar thread here:

Ok I tried this and it did find something in stage 2 of 3 but the scan didn't get past 60% the CMD command just stopped and was ready to enter a new command without showing a reason why it stopped.

I will try formatting after i tried the CHKDSK on an other pc maybe it will finnish there.

what about the dld result ?

 

[lonewolf7]

Ok, keep us posted.

 

[Steven_3020]

what about the dld result ?

Both of those tests passed


The CHKDSK command gives a little more information now it says insufficient storage space to correct errors.
I have been trying to delete some unimportant data but it wont delete everything i selected.

 

[scout_03]

did you try to cut and paste the data somewhere else even a rewritable drive to free some space because your hdd must near full capacity and could not even made a defragmantation .

 

[lonewolf7]

If you are trying to Delete by right clicking then it may wont work, try Shift + Delete to delete the files.

I just tried deleting data i didnt need but i have +200GB free on the disk

If you are trying to Delete by right clicking then it may wont work, try Shift + Delete to delete the files.

Ok I'll try that didnt knew about Shift+Delete

Whats the difference actually between the 2 methods?

 

[scout_03]

do a full deframentatition of this drive and see if it gain in speed .

 

[lonewolf7]

Deleting files with right click will go to recycle bin and will take up disk space of the corresponding drive. Shift + Del to files will go for ever in a way(not really), but will not take up the disk space of the drive.

Ok so in the end I tried formatting the drive but that didnt work not through windows nor CMD. So I put the disk in an other pc tried formatting there and it worked like a charm. Then i put the disk back in the original pc did the HD Tune benchmark again and all looks well.
