Why can I copy to an external hard drive but not from it?

I have a SATA hard disk, using a sort of case I can use it as an external hard drive. When I copy files to my hard drive there is no problem , but when i try to copy from the HDD it freezes after few seconds, mostly after 8-10% of copying data.

I have been searching for solutions but couldn’t find anything effective. I have tried formatting several times.

Any ideas?

    How to Check the Disk on an External Hard Drive
    http://www.ehow.com/how_6930762_check-disk-external-hard-drive.html

    try also to defrag see if combined operations will help to solve the problem.

    ot can also be due to CRC errors if something wrong with the files

    What are the errors that are showing up in the Event Log?

      If you are running Vista or later, right-click on Computer and select Manage. Respond to UAC if necessary. In the left pane, expand Event Viewer then Windows Logs then select System. In the right pane select 'Filter Current Log...'. In the Filter dialog box, check Critical, Warning, and Error. Search the center pane for entries with a Source of NTFS or Disk. They should be the internal system errors that are happening when you are trying to copy. Post samples of the typical events that are happening when you ate trying to copy here.

      the warning goes on recurring until i cancel copying
      and, The IO operation at logical block address 69528 for Disk 1 was retried
      in this statement the address is different in each warning
      Looks like computer tries to read address but couldnt and go to next address and again couldnt ...

      If you can, remove the disk from the external enclosure and install it as an internal drive on a system. Open a command prompt and run 'chkdsk letter: /f' where letter is the drive letter assigned by Windows.

      You could try this command while the drive is connected externally, but I have found that some USB enclosures will not let this work properly so you are better off taking the extra effort to use it internally.

      If the chdksk operation comes up clean without repairing any faults, you have a problem with the external enclosure. Otherwise you should consider backing up all of the data on the drive and obtaining a new one.

      Another possibility is that the USB enclosure you are using is faulty and may have caused the faults on the drive (unreported write errors). There are utilities such as SpinRite that can do very thorough diagnostics on the drive although the last time I looked, a single license of SpinRite cost about as much as a new 1TB SATA drive.
