How to fix Error 1102 on Windows 11

Why This Error Happens

Error 1102 is generated by the Removable Storage Manager (RSM) or tape backup driver stack when a read/write head unexpectedly hits the Beginning-of-Tape (BOT) marker or a partition boundary during a restore, append, or seek operation. This typically occurs because the backup software lost track of the tape’s logical position — often due to a corrupted tape header, a media/firmware mismatch, or an interrupted previous backup job that left the tape catalog out of sync. It can also occur if the tape drive’s device driver is outdated or the tape itself is physically worn, causing incorrect position reporting to the OS.

Step-by-Step Resolution Guide

  1. Update the tape drive driver
  • Open Device Manager (devmgmt.msc) → expand Tape drives.
  • Right-click your tape device → Update driver → Search automatically for drivers.
  • If a newer driver exists from the manufacturer, download it manually from their support site and install via Have Disk.
  1. Reset the Removable Storage Management service
  • Press Win + R, type services.msc, and press Enter.
  • Locate Removable Storage (or the backup vendor’s tape service, e.g., “Backup Exec Device & Media Service”).
  • Right-click → Restart. If disabled, set Startup type to Manual or Automatic and start it.
  1. Rewind and re-verify the tape position
  • In your backup software (Windows Server Backup, Veeam, Backup Exec, etc.), run a Rewind or Retension command on the tape before starting the job again.
  • This resets the head position and clears any stale BOT flags left from an aborted job.
  1. Check and clean the tape/drive hardware
  • Run a manufacturer-approved cleaning cartridge through the drive — dirty heads often cause false BOT signals.
  • Inspect the tape cartridge for physical damage or an unseated leader pin; try a different known-good tape to isolate whether it’s media-specific.
  1. Rebuild the tape catalog/database
  • If using Windows Server Backup or third-party software, delete and re-import the tape’s catalog entry, then perform a fresh full backup rather than an append, to reset positional metadata.

Alternative or Verification Steps

  • Verify the fix: Run a small test backup job to the same tape and confirm it completes without triggering Event ID 1102 in Event Viewer (Windows Logs → System, source: RsmMS or tape driver name).
  • Alternative: If the error persists across multiple tapes, replace the tape drive/SAS-SCSI cable, as this points to a hardware-level positioning fault rather than a software or media issue.
