System freezes when copying files.

Question

Dear All,

It's been more than 3 days trying to copy some large files from one HDD to another HDD.
After few minutes all the system freezes (including mouse cursor), Ctrl-Alt-Del is not working and the only option is to press the reset button.
I ran the sfc /scannow but no errors detected.

I cannot figure out why the systems halts.
I had never this issue before.

When copying starts after few minutes the system freezes and I receive a message that the system cannot read files from the source disk.

Can you please help me?

Thank you very much!!

PS) Some HDD ae formatted with 64k allocation unit size due to very large files on them.

Hi Demetrius Karantinopoulos,

It seems you have problem with IO and leads to system hang.

Please download CrystalDiskInfo to check for the health of your disks.

Answer 3

Dear S.Sengupta,

Also to mention that I have notice that the system halts when doing Cut---->Paste
(not Copy----->Paste).

Answer 4

Dear S.Sengupta,

Thank you very much for your reply.
I follow all your instructions and the chkdsk command did not detect any errors or bad sectors on disk.
Let me correct my previous message.

The copy procedure fails due to fail of the Destination disk (not the Source disk).

I wrote Source disk in first message.
I was wrong.

It's the Destination disk.

Answer 5

Your HDD is very likely failing

Open Command Prompt as Administrator

Run:

robocopy X:\ Y:\ /E /R:1 /W:1 /MT:8 /LOG:copylog.txt

Replace:

X: = failing/source HDD

Y: = healthy destination HDD

After that:

Run:

chkdsk X: /f /r

Only to confirm disk condition
