Hi all,

As part of upgrading, I'm testing my hard drives... On one I have the following in the report from smartctl:

SMART Attributes Data Structure revision number: 16
Vendor Specific SMART Attributes with Thresholds:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED
WHEN_FAILED RAW_VALUE
[...]
5 Reallocated_Sector_Ct 0x0033 001 001 005 Pre-fail Always
FAILING_NOW 25


You have to look at these three values:

5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always
- 0
197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always
- 0
198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline
- 0

All disks develop a number of bad sectors during life, even before leaving the shop. They have a number of prepared sectors to remap those bad sectors (during write operations). When those sectors are spent, the disk is caput, dead. Any new sector can not be remapped, and any way, it has too many bad sectors to trust the disk any more. Not worth it.

Make a wall clock with the dish :-)
