Re: Backup Fails: "C: is not a valid drive or you do not have access"

Tech-Archive recommends: Fix windows errors by optimizing your registry

I have had this problem in the past. I formatted the tape using the Exabyte
diagnostic tool [the same tool you use to update the firmware] and the
problem went away.

Hope this helps

Hi James:

In addition to the suggestions you received from James, I find that
Exebyte
does not like their tape drives to be on the same SCSI controller as RAID
hard drives. They maintain that the timing is different, and suggest
strongly that you put their tape drives on a separate SCSI controller, one
that is not intended to be a RAID controller.

Hi Daniel

Since we are able to backup to a network share that would tell us that
NTBackup is working.

I would suggest making sure that the firmware on your tape device is the
most recent available from Exabyte along with the drivers for this
device.
You should also ensure that the drivers for the SCSI adapter are fully up
to date.

Thanks

Can you try to perform the same backup to a partition that is separate

| Hello Everybody,
|
| On a SBS2k3 Premium backup was failing before due to an Exchange
corruption,
| that was fixed with: Eseutil /P Eseutil /D Isinteg -fix -test
alltests.
|
| Now the backup fails while backing up C: drive. In the event logs I get
| event 8001 and 8019, however the Exchange database is on D: drive ( I
tried
| to backup excluding system state or Exchange database but I get same
error).
|
| "Error: The device reported an error on a request to write data to
media.
| Error reported: Hardware failure.
| There may be a hardware or media problem.
| Please check the system event log for relevant failures.
| The operation was ended.
| Backup completed on 2/19/2007 at 10:06 AM.
| Directories: 322
| Files: 1896
| Bytes: 221,573,436
| Time: 1 minute and 23 seconds
|
| Error: C: is not a valid drive, or you do not have access."
|
| If I backup using NTbackup I get same errror, however if I backup to a
file
| on a second server that works OK
|
| The tape backup is an Exabyte VXA-3, tried to uninstall, reinstall but
same
| error message.
|
| Has anyone encountered this problem before? or do you have suggestions?
| Your input is much appreciated.
|
| Cheers,
| Daniel
