Re: Zero fill it, restore from your backup

I'd "zero fill" the drive.  The drive manufacturers make software that can do that for you.  It's probably either a WD or Seagate drive, and both of them offer utilities that can do that for you.

Basically, that makes sure that all sectors are written to; meaning that the drive firmware will automatically mark those sectors as bad at the firmware level in EEPROM (versus just marking those sectors as bad at the file system level like you'd get running disk utilities like chkdsk) when it detects errors trying to write to a problem sector.

Sometimes, scan utilities that check for read errors only will miss borderline sectors (and even if they identify read errors, they're still only marking them as bad in the file system, versus in the drive's EEPROM).

So, zero filling the drive is a much better way to go to insure drive reliability going forward, and will give you a much better idea of the drive's condition so you can make a more informed decision about whether or not the drive should be replaced).

From what I gather from your other posts in this thread on the subject, you already have a good disk image backup that you could use after using a destructive process like zero filling one.  So, I'd suggest taking that approach (zero fill it using the disk manufacturer's software and run their diagnostics after doing that).Here's a post I made on the subject recently, that includes links to the drive manufacturers' software for that purpose:

I followed your link and read through your post. My drive appears to be a WD drive and I have downloaded the appropriate Lifeguard Diagnostic, but it does not appear to be an iso image for a bootable CD/DVD. Instead it is only a Windows based app and I don't see how I can use it on the Windows disc without removing it, replacing it with a different system disc, booting, attaching the original drive as a usb drive and then zero-filling it.

I agree that zero-filling the disc is probably the best way to proceed, but this app does not appear to give me that option without taking my system apart (to replace the disc. In my system it is not a simple matter to swap out the drive) and replacing the disc.

Unless, of course, I am missing something. At least that has the feel of familiarity ...
