Endpoint Encryption

Issue/Introduction

Symantec Endpoint Encryption will automatically start encrypting the drive and will do so even if the SEE Client is unable to connect to the SEE Management server.  In fact, even if the SEE Client is unable to connect to the SEE Management Server, recovery keys will still work (Connectionless recovery).  In this way, SEE is a very robust and reliable Drive Encryption solution.   As part of this robust solution SEE will also check for bad sectors on the disk.  If a bad sector is encountered, it will halt the encryption process to ensure data integrity is not compromised right off the bat (If a bad sector resides on the disk, this is indicative of a bad drive and should typically be replaced).

 

Cause

Errors observed in the SEE logs you'll see the following errors (in bold): 

 

[01/21/21 17:32:51][ERROR][4212][0x1AE0][SEDE][SYSTEM][(sHandleDriverEvents) : sHandleDriverEvent: Encryption paused due to bad sector on disk.][driverEventHandler.cpp:485]

[01/21/21 17:33:35][ERROR][4212][0x1AE0][SEDE][SYSTEM][(sHandleDriverEvents) : sHandleDriverEvent: Encryption paused. 8 bad sectors found on disk.][driverEventHandler.cpp:492]

Resolution

If a bad sector is encountered, Drive Encryption will not proceed.  When this is the case, Symantec Enterprise Division recommends the following options to consider:

1. Replace the hard drive (recommended) - When a bad sector is encountered, this is a rare condition and usually means the drive is defective.  Although bad sectors could be repaired, there is no guarantee more sectors on the disk will not be problematic.  As a result, replacing the drive with a new drive is the best option and a bad sector is most likely covered under warranty. 

2. Attempt to repair the bad sector may be possible with third-party disk repair utilities.  Also, you could run the following command to see if this fixes the sector:
"chkdsk /r"
