In general, the failure rate during deployment is about 1 in 1000, with remediation taking place afterward.
We recommend that you query the
SMART status of the drive. SMART can ascertain the health of a drive, before it's encrypted.
Use the following steps to determine the health of the drive before encryption when the following criteria are met:
- Your environment includes older computers with important data.
- There's no recent backup.
- Run chkdsk in read-only mode (no switches).
IMPORTANT: Using chkdsk with the - f or -r switches is not recommended. If the internal bad block remap table fills up, the drive might become unusable.
- Analyze the results and determine the number of bad sectors on the disk.
- Encrypt the disk only if few or no errors are reported in the chkdsk scan report.
IMPORTANT: We recommend that you always back up data before you encrypt a drive that contains critical data.
