Hi Amit, Several things might cause this.

Hardware wise, the write protect switch may be broken in the tape drive. (two finger switches / levers to the side of the cartridge)

This is likely if you have just manually ejected a tape with a screw driver (not recommended).

However there are also software issues that could cause this. For instance Backup Exec could have been asked to prevent overwrite for 12 months. This is totally software based and is NOT dependent on the WP switch.

My top guess is that the drive will need repair though as this can be a common fault.

this may be a limitation on your motherboard. please check if your motherboard supports this much capacity. If you have another pc or laptop that is about a year or two, check if they would recognize the the capacity of the drive correctly. if not you may want check with quantum about their drives.

DLT-S4 tape is stuck in Quantum drive all 3 LEDs flashing together. Eject tape button does not work, how to get the tape out?


Hello, on some of the older DLT drives, if you press the 'eject' button several times the drive firmware attempts an unload operation. I'm not sure of the number of times you have to press it though...try pressing it in and releasing it 3 times (in quick succession). If that doesn't do anything, try 7 times.
It's worth a try!

We are having an issue with our backups. The system event log says there is an error 7 and lists the tape drive as having a bad block. However the quantum diagnostic tool shows the drive to be healthy. ...


Event ID-7 is a "Bad Block" on the Tape being using. By design, when a Bad Block is encounter, the Tape Drive "Seizes the Tape" and goes offline. It can sometimes be difficult to get the Tape Drive to release the Tape. Refer to the Users Manual for instrcutions on how to Reset the Tape Drive. Sometimes applying the Firmware Update willl reset the Tape Drive and Eject the Tape.

Do not assume the Tape is Bad, but do not re-use until tested. The Tape may be Bad, the Tape Drive may simply need Cleaning or the Tape Drive may be Worn or Damaged. If you are using 3rd Party Backup Software, such as Backup Exec or Yosemite, you wan want to check the Removable Storage Servcie to see if it is set to Manual or Automatic. Any Tape Devices would need to be first Deleted in the Library Section of Removable Storage, then Sop and Disable Removable Storage. Since Removable Storage is in effect NTBACKUP, this Service can interfere with the Operation of your Backup Software and generate "Bad Block" Errors.

To Test the Tape with your Quantum Tape Drive, use a tool called XTALK ( xTalk-6.4.1.1_Quantum_Setup.exe ) that is found on Quantums Website http://www.quantum.com/ServiceandSupport/Index.aspx

You may run a write_read_full Test on the Tape. Be sure to Clean the Tape Drive first. If it fails the Tape, try it with a 2nd Tape, If it fails again, suspect the Tape Drive.

How do I remove a stuck tape?


Power the unit down and very carefully unscrew the cover.  The greatest care must be when taking the tape out so that you don't bend the unit.

Consider blowing it out to get rid of dust and it very likely has a problem that will require service.  My quantum px502 had a stuck tape and I took the cover off but the picker was already off track - $700 to fix that and replace a sensor.

It gets heavy use and was serviced before in the three years it has been running.

Not backing up


Run Quantum's DLT from the following link:
http://www.quantum.com/ServiceandSupport/SoftwareandDocumentationDownloads/Sage/Index.aspx

Understand that a bad tape will produce failed tests, so try to use a "known good" tape.
Regardless of the Pass/Fail results, the LogPages are as important, as they capture past failures and may point to the real problem.

DLT V4 Driver


Most tape drivers are loaded from withing the backup software. Symantec and CA work like this. I'd start there.

If not you have to start the remote storage service and check in device manager to see what it defaults to and see if will find the device for you.
