EFI System Partition Has Some Bad Sectors

Thread needs solution

Hello All,

First, I have to say I know just enough to be dangerous.

I recently had a Microsoft update go wrong causing me to restore my computer using a backup.  Everything seems to be good, except that I can no longer perform backups.  I get the message "File system error is found. Consider checking the disk using Check Disk Utility."  I used chkdsk /f /r to check my OS disk C: (RAID0) and data disk D: and they are good.  I then checked the hidden partitions on my C: drive and found that the EFI System Partition has "12,288 Bytes in bad sectors".  I attempted to repair it with chkdsk /f /r.  This did not work.

I think I have to repair this partition before I will be able to perform backups.  Can I delete or copy the files in this partition, re-format (GPT Fat32), confirm good format with chkdsk, and recreate the files?  If so, is there a step by step tutorial somewhere?  Any other options?  It boots up fine, so I have access to the command prompt.

Dell Alienware Area 51 with RAID 0 OS drive, Windows 10, UEFI, GPT

Any help would be GREATLY appreciated,

Joseph

Joseph, welcome to these public User Forums.

For this type of issue I would recommend using the diagnostic tools provided by the disk manufacturer to try to resolve the bad sectors.

Dedicated diagnostic utilities from the disk manufacturers take the longest time to complete the checks, but provide the most accurate methods of checking whether the disk is good or needs replacement:

 - Western Digital drives: Western Digital Dashboard

 - Seagate disks: SeaTools for Windows

 - HGST disks: HGST Windows Drive Fitness Test (WinDFT)

 - Intel SSDs: Intel Memory and Storage Tool (GUI)

 - Samsung drives: Samsung Magician

 - ADATA drives: ADATA SSD ToolBox

 - Kingston SSDs: Kingston SSD Toolbox, Kingston SSD Manager

 - Transcend SSDs: Transcend SSD Scope

 - Silicon Power disks: SP ToolBox

 - Toshiba disks: Toshiba PC Diagnostic Tool Utility

 - Crucial disks: Crucial Storage Executive

 - SanDisk disks: SanDisk SSD Dashboard tool / SanDisk SSD Dashboard user guide

In terms of making backups while this issue is present, then try doing the following.

Omit the EFI System Partition from your main OS disk backup task (deselect the partition from the task source selection).

Create a separate backup task for just the EFI System Partition on its own, then in the Options > Advanced settings, select to ignore all bad sectors.
