HI,

I am using FC11 and getting SMART alert on GUI, alerting as disk failure.

Code:

ID         : 197
Attribute  : Current Pending Sector Count 
Current    : 200
Worst      : 200
Threshold  : 0
value      : 1 sector
Status     :  Failing 
Type       : old-age
Updates    : online

Is this logical bad block and repaired after format or it is physical bad block need to change disk.

thanks.

From http://en.wikipedia.org/wiki/S.M.A.R.T.

Quote:

Number of "unstable" sectors (waiting to be remapped, because of read errors). If an unstable sector is subsequently written or read successfully, this value is decreased and the sector is not remapped. Read errors on a sector will not remap the sector (since it might be readable later); instead, the drive firmware remembers that the sector needs to be remapped, and remaps it the next time it's written.

The most important thing that stands out in the article to me is this:

Quote:

in the 60 days following the first scan error on a drive, the drive is, on average, 39 times more likely to fail than it would have been had no such error occurred.

Personally, I'd be making sure my backups were solid and saving up for a new drive.
