Hard Drive Sentinel has flagged a drive in a storage space as having 10% bad sectors, and estimated to fail soon.
When I go into Storage Space Management, I do not see the optin to remove the drive.
Is there a way to remove and replace it or do I have to wait for it to fail?
I have never used storage spaces, so speak from zero experience & knowledge, but it seems to me that you have too much data to be able to remove that 931GB drive, without the data being transferred to the 1.36TB drive which is flagged as 'iffy'. My guess is that Windows won't let you put any more on the latter drive, so until you add another, none of the others can be released.
First, you need to resolve the problem of probably failed drive (yellow warning sign) - replace of remove it, re-calculate parity. After this, you can physically disconnect the drive with SMART errors, then Remove appears as an option. Do not remove two disks concurrently from Parity space, it results in loss of data.
Or you can backup data & create new storage space.
