Have you performed LOG file backup?
When the disk is faild you was be able to run BACKUP LOG file WITH NO
TRUNCATE option. Restore the whole database and apply all log files with NO
RECOVERY option and the last one with RECOVERY option.
For more details you have to read BOL.
Sorry about losing the data.
