HI all - hope you can help with an issue I'm having.
Model: Terastation HS-DH2.0TGL/R5
Firmware: v2.14
I've had a Terastation for a couple of years and been backing it up to an external Maxtor Basics USB HDD on a weekly basis for some time.
Unfortunately last week the USB HDD failed so I bought a new WD20EARS 2TB drive - http://support.wdc.com/product/download.asp?groupid=608?=en - and slotted it into the USB caddy. Formatted it to XFS and kicked off a backup overnight.
Next morning found the backup had stalled - no disk activity, no error messages in the backup log file, and the web interface stated a backup was in progress. Checked the last file in the backup log on the USB HDD to find it had partially copied - ie filename something like '.MyFile.txt.TH6k8d' - and the timestamp was 4:04am
Reformatted the USB HDD and tried again next night - manually starting the backup this time. Same problem - no errors in the backup log file, web interface stated backup in progess, last file (different file this time) partially copied & timestamped at 4:04am.
Thought it was a bit odd so adjusted the Terastation date & time so 4am was within daylight hours and tried again. Same issue - backup stalled at 4:04am ''Terastation time'.
I'm at a bit of a loss to explain what's happening. The only consistent element is the stall at 4:04am. Doesn't appear to be related to a specific file or amount of Gb transferred. The new HDD seems physically ok - I've formatted it to NTFS, connected it to a PC via the USB caddy and left files copying to it overnight - past 4:04am - with no problems. I've also run the quick version of WDs Data Lifeguard Diagnostics with no problems found.
Can't see what else the Terastation might be doing at 4:00am. There are no other backup jobs scheduled and in any case the backup to the old USB HDD must have on occasions run past 4:04am (I scheduled it to start at 2:30am).
Any ideas?
Thanks,
DiscoStu.
