sciascia1 Posted March 26, 2012 Report Share Posted March 26, 2012 Hi There, We're having issues trying to track down a "Trouble communicating" error with a backup disk. The disk in question is a removable 2TB hard drive and we've tried it in two different caddy's and tried connecting it via Firewire and eSATA. But the backup fails (at a different point each time) no matter how the disk is mounted. I've also tried copying several gigabytes of data on/off the disk using the finder but MAC OSX doesn't seems to have any issues with the disk. Is there something specific Retrospect requires in order to talk to a disk that might have failed or that we might've missed? Any help would be much appreciated.

sciascia1 Posted March 26, 2012 Author Report Share Posted March 26, 2012 Sorry, should also mention that we've repaired the disk in Disk Utility with no issues and the disk has been erased and re-added to the media set several times over the past month.

Lennart_T Posted March 27, 2012 Report Share Posted March 27, 2012 It isn't clear if the disk in question is the source or a member of the destination? (The destination is always a "media set", not a disk or tape). If it is a member of the destination, have you tried another source? When the disk was erased, did you zero out all data (which takes hours)? Or was it just a fast erase (which takes a minute or two)? Quote Link to comment Share on other sites More sharing options...
sciascia1 Posted March 27, 2012 Author Report Share Posted March 27, 2012 Thanks heaps for the reply and sorry for the confusion - the disk is a member of a destination. I formatted the disk and left it zeroing all data overnight so am trying a new backup now. Will post again if I have issues but obviously something was wrong with this particular disk as the other 2 members have been fine.

Lennart_T Posted March 27, 2012 Report Share Posted March 27, 2012 If the disk supports S.M.A.R.T. status, you can check that in Apple's Disk Utility. It doesn't say "OK" if it is OK, just "Checked" (or something to that effect). Quote Link to comment Share on other sites More sharing options...
