disk reformatting error #304
Description
Problem description
Having an issue with the StorageDSC 'DISK' command randomly reformatting drives after the initial formatting is completed.
After initial drive setup success on 7/8, 7 days later, on 7/15, the E drive reformatted without warning. This appears to be related to the DSC consistency check on the disk. The disk was expanded, but I wouldn't expect the DSC to reformat the disk on this expansion since I didn't specific a drive size. I'm not even sure where the drive sizes are coming from that it's complaining about.
Looking for the following:
- Confirmation that this is indeed the reason for the refomatting.
- if so, where are the drive sizes coming from.
- what I need to do in my dsc config to prevent this in the future.
Appreciate the assistance

no suggested solutions at this time as I'm not even sure it's the issue and if so, why it's an issue.
