# X_STORAGE_PARTS_INVALID

## Means

the parts named do not match the parts stored

## Typical cause

completeUpload was handed a part the disk never received, parts out of ascending order, or an etag that is not the stored one

## Fix

`listParts({ disk, orgId, key, uploadId }) to see what landed, resend the missing part, then completeUpload again`
