Question : Problem: Disk Errors

Hi, I have 2 Dell Dimension PC's. A 3000 and a 5150.  Doth are reporting disk errors in the event viewer.

 1. Event ID 7 "The device \Device\Harddisk 0\D has a bad block".
 Dimension 3000 - Samsung SP0802N hard drive

2. Event ID 11 "The driver detected a controller error on \Device\Harddisk 0\D"
 Dimension 5150 - HDS728080PLA380 hard drive

The Dimension 3000 will not load IE , but other than that it boot ok.
The Dimension 5150  boot up fine but it has shut down on its own once or twice.
I ran diagnostic on both from the setup menu and both passed.
Is there anything else I can do to troubleshoot or do these drive need to be replaced. Any suggestions would be appreciated.

Answer : Problem: Disk Errors

For
 1. Event ID 7 "The device \Device\Harddisk 0\D has a bad block".
 Dimension 3000 - Samsung SP0802N hard drive
 - you can run chkdsk /f in normal mode, or chkdsk /p in recovery console.
 - This will try to fix any file system corruption, recover data from bad sectors on HDD and copy it onto good sectors
  - If there are Bad sectors, chkdsk or any other software wil NOT repair bad sectors; they would remain as they are, running these utilities would only allow you to salvage whatever data/files you can
 - You can try a low-level format if Samsung has any utility like that, this may repair the bad sectors; but my exp. has shown they always come back and the HDD has eventually to be replaced.


2. Event ID 11 "The driver detected a controller error on \Device\Harddisk 0\D"
 Dimension 5150 - HDS728080PLA380 hard drive
 - Attach the HDD to another controller, replace the cable
 - Update the BIOS and whatever firmware updates are available
 - Then run chkdsk to check if there are any bad sectors on the HDD
 - If it comes out clean, the HDD would need not be replaced
