Hello.
smartctl -a shows I have some bad sectors in 2 partitions (full output below).
I am trying to correct those errors so I can use the disk again (self-test reports a Read Failure).
Questions:
- Current_Pending_Sector value is 368. Does that mean there are potentially 368 bad sectors on the drive?
- After correcting these 368 bad sectors can I then mount the drive?
- I will use dd to zero out the bad blocks/sectors, correct?
- Before that can I recover the data in these bad blocks? Just in case the data is critical data...
- From the above outputs, is any PHYSICAL problem with the disk? After fix all the bad sectors it is going to work again?
Thank you so so much!!!!
