For anyone with a Western Digital SN580 or SN770 SSD there is currently an issue with Windows 24H2 and HMB. HMB is used in drives that don't have a DRAM cache.

This issue causes the drive to have read/write errors in windows and can potentially corrupt your windows install if it is your boot drive.

See this thread for more information:


Registry Fix:

I experienced the error on my SN770 (luckily it was a secondary game drive) and it corrupted data on my SSD.
 
Updated my SN770 2TB with the new firmware. HMB now showing at 64MB so problem is fixed.

Replaced it this morning with a Samsung 990 Pro from OcUK though.
