Hi All,

I have a Terastation Pro 2 running RAID5 and I had a drive go bad, so I bought a 3TB external USB drive formatted it properly and proceeded to backup the Terastation. I was able to backup the Terastation and it said it was successful, but before I try to rebuild/replace the drive with errors (drive 4 BTW) I want to to be able to access the data on the USB drive and verify that everything is there and was successfully backed up.

I have logged into the Terastation and added my user and the admin user full read/rights access to the USB drive, but when I try to access it via the NAS Navigator2 on my PC I get an error message that says I don't have permission to access the backup. In NAS Navigator I click on browse-->usbdisk1--> 201606011434-->Home and I get the following error:

Windows cannot access\\TS-HTGL164\usbdisk\2016066011434\home
You do not have permission to access \\TS-HTGL164\usbdisk\2016066011434\home. Contact your network administrator to request access.

I can access my other network resources that are on the Terastation, (I have drive mappings) from NAS Navigator but not the USB drive. I have not mapped drives from my Windows PC to the external USB drive.

Can someone offer insight as to what I might be doing wrong? Do I have to map a drive through Windows first to access the USB drive via Nas Navigator? I would like to perform the rebuild on the drive that is showing errors, but not until I can ensure that the backup as successful.

Thanks

Gordon,

This is somewhat tangential, but the TeraStation should rebuild the array once a new drive is inserted, assuming the correct procedure has been followed.  I understand your concern to have a backup, and the rebuild can take a while depending on the size of your volume, but you are at risk while the defective drive is in there until the RAID is rebuilt.  I have two 12 TB Terastations and I worry (a lot) every time I have to wait for the rebuild.  I have had several drives fail but never lost any data (yet).  I have standby new drives and replace the failed drive immediately.  That being said, I don't actually have a backup system in place; for my purposes I use the mirrored RAIDs.  But I'm considering a third drive for backups.

Good luck with the permissions problem, though.  I hope someone can answer that for you.
