End of file reached. Error 38 in SQL. Passes verification checks

Having issues restoring a database in SSMS, error 38. The databases are transferred up to google via their Drive API. Download it on my side and has error. If I transfer it through teamviewer from client PC I still get the same error. Only happening on two clients the rest are fine. I have tried backing up with FORMAT options and WITH CHECKSUM. Both succeed and backup is taking when verifying. I have ran restore fileheaders only and get proper data except the physicalname path has a lowercase 'c' for the drive on the problem databases. I have read this could be a corrupt database but I don't understand how the checksum and verify sql functions pass if so. Any insight would really help. This is the backup command used in C# "BACKUP DATABASE " + database + " TO DISK = '" + database + "_" + dateTime.ToString("yyyy_MM_dd_HH") + "_CloudBackup.bak' WITH NAME = 'database', INIT, CHECKSUM" EDIT: Running

check

on the database produced no errors. I have tried updated the physical name of the .mdf and .ldf it does not work still. Taking a backup from SSMS produces a valid backup file. It has something to do with the services I wrote. EDIT 2: I am restoring through SSMS GUI. I have also tried

RESTORE DATABASE db_name FROM 'backup_path'

Commands

RESTORE VERIFYONLY FROM DISK = 'backup_path'

On both computers, mine and the server PC yields "The backup set on file 1 is valid."

RESTORE FILELISTONLY FROM DISK = 'backup_path'

Have only test on my PC. Returns paths to mdf and ldf, no errors. Both PCs have sql server 2012 (SP1)
