I'm having trouble figuring out if that drive is supported. Searching for ATDEA2A on Sony's web site (http://www.storagebysony.com) returns no results. Even Google has only one (cryptic) result for this model number. Sony makes several 130 GB standalone drives and several libraries incorporate them. Assuming it's a standalone drive, it should work with the drivers that come with 10.0 as long as it is on this list:

Backup Exec uses the device inquiry string to identify drives. On a SCSI attached drive, your SCSI adapter will generally output these when the system starts up. You'll notice that the compatability list I linked has the inquiry strings we are looking for listed in the file, so, for example:

SONY^^^^SDX-500C

Should be output by your SCSI card if you are using the SDX-500C 130GB SCSI drive. Also note that the compatability list uses carrots to represent spaces.

Additionallly, ensure the following

- Disable Removable Storage (RSM) service.

- Ensure that SCSI ID 0 & 1 are not being used, as they are reserved for bootable devices. SCSI ID 6 should also be avoided.

- "Changer" or "Loader" should be configured at a lower SCSI ID than the drive. (e.g. Changer = 2, Drive =3)


Further,
- Power off the storage device
- Shutdown the server
- Power on the drive and wait till it is stable
- Reboot the server
- Verify the results
