Fix Storage Optimizer error 0x8900002A, requested operation not supported by hardware

You can prevent your Windows 11/10 device from recording Storage Optimizer error 0x8900002A, requested operation not supported by hardware in the event log by following the necessary steps suggested as follows:

  1. Initial checklist
  2. Windows Update
  3. Disable scheduled optimization
  4. Run the CHKDSK and SMART test

Let’s take a look at the description of each of the recommendations.

1]Initial checklist

Before proceeding, check if the drive giving the error is an SSD. If so, your SSD may not support TRIM. To check this you can use a tool like HWiNFO and look at the drive properties – it should be under Transfer methods. However, there are arguments in some quarters about whether it is acceptable to defrag SSDs; however, it is best to err on the side of caution and disable defragmentation on your SSD. On the other hand, if the disk in question is not a Solid State Drive but a rotating hard disk, the classic platter-type hard disk, then TRIM is not supported. Also, Windows shouldn’t run TRIM on HHDs, but a bug has already been reported with Windows 10 version 2004 about this; since this is not a supported feature, however, on hard drives it can be ignored.

However, if this is not the case for you or you just don’t want Event Viewer to log this error, you can follow the suggestions below.

2]Update Windows

As already indicated, the Storage Optimizer Error 0x8900002A is not a problem in itself, but in fact one of the problems and known problems or bugs on Windows 10 version 2004. So if you are currently using this version of Windows (which ended maintenance on the 14 December 2021), you can simply update to the latest Windows version/build on your device.

3]Disable scheduled optimization

Disable scheduled optimization

In Windows 11/10, disk defragmentation is a way to organize your disk. It can organize the data stored on the disk so that your computer’s speed is increased and becomes more efficient. Since running the built-in disk defragmenter or drive optimization tool triggers the error in view, the logical step to take is to disable scheduled optimization for the drive in question. If you need to run disk defragmentation, you can try one of the free third-party defragmentation software for Windows 11/10.

4]Run the CHKDSK and SMART test

This suggestion should be dealt with after the fact. To ensure that your disk is in perfect condition, you can run CHKDSK to repair bad sectors that could trigger a false positive. You can also run a SMART test to see the health of your drive.
