ReadyNAS 102 not displaying files while also reporting 2/3 of the storage drives are full

This makes sense, but I haven't been able to restore anything effectively. Either the restores I initiate fail or they do not provide me with any additional files. I also checked the log files and can't find anything productive to suggest that the loss of data was initiated by an action with shares or drives. I spoke with someone from the business and they explained that this drive is very infrequently accessed, but it likely stopped working after some rearranging. I'm assuming they pulled the power instead of letting it shut down gracefully, so I also wonder if anything is stored on volatile memory that's necessary to access this data.
