bravotech Posted December 6, 2005 Report Share Posted December 6, 2005 Just encountered this 1 site where an installation of 6.5 professional was previously working, and just recently developed a problem. All scheduled duplicate jobs and backup to file jobs continue to be error-free. Manual backup to DVD disc fails due to No backup devices found. I installed the latest 6.5 update. Tried uninstalling and reinstalling. Still not resolved. Envionment tab, it shows: dEVICES visible using ASPI Any suggestions on what to try next?

natew Posted December 6, 2005 Report Share Posted December 6, 2005 Hi OS and hardware specs please? Retrospect won't break on its own like this. What else has changed on the system lately? Updates? New hardware? Nate Link to comment Share on other sites More sharing options...
bravotech Posted December 6, 2005 Author Report Share Posted December 6, 2005 It's one of those not-so-frequently maintained client site. Items remained unchanged: Windows XP Professional Service Pack 2 (build 2600) Retrospect Professional 6.5 w/ RDU54 update AOPEN DUW1608/ARR Intel® 82801EB Ultra ATA Storage Controllers WinXP Promise FastTrak TX4000 Controller 2x 200G HD mirrored (hardware) Recent changes (2 months): joining domain windows updates (the usual) removal of mbsa 1.x shavlik hfnetchk 4.3 (at server) agentless on client side Nero continues to work ok, tested erase disc (DVD+RW) and burning data disc. The problems appears to be Retrospect somehow fails to recognize the device. ASPI issues? NT device drivers issues? All tests performed on domain admins account, which is given local administrators group. Link to comment Share on other sites More sharing options...
bravotech Posted December 8, 2005 Author Report Share Posted December 8, 2005 Another thing I noticed... In Configurate Devices window, on Environment tab: at one point the first item was shown in strange font/characters. Every single character is a box. Should it be using NT Passthru devices or ASPI? What are the pros and cons? Link to comment Share on other sites More sharing options...
natew Posted December 9, 2005 Report Share Posted December 9, 2005 Hi That is likely the problem. Retrospect uses the information listed there to determine which driver to load for the device. That item is called the "inquiry string" and is obtained directly from the device. If Retrospect doesn't recieve a valid inquiry string from the device a driver will not load. Firmware problems, IDE drivers or a faulty drive can cause this kind of thing. When you are having trouble with a device it is a good idea to try both connection methods. What are you using now?

bravotech Posted December 9, 2005 Author Report Share Posted December 9, 2005 As indicated in original post, it was using ASPI. I just now went in and changed to NT passthru per KB #27109. Drive is now recognized. Backup will presumably work, pending confirmation when client return to office tomorrow. Currently no disc in drive, and I'm remote off-site. I think something must have caused Retrospect to switched to ASPI mode. There was no upgrade to ASPI which was provided by install of Nero 9 months ago. Is there a way to tell which exact ASPI driver Retrospect was trying to use? There's system ASPI as well as Nero ASPI installed. Link to comment Share on other sites More sharing options...
natew Posted December 9, 2005 Report Share Posted December 9, 2005 Hi With 6.5 Retrospect will use ASPI when it is available. I would bet that ASPI was installed along with another application somewhere along the line. As long as the NT Passthrough setting is checked Retrospect will not use ASPI.

bravotech Posted December 13, 2005 Author Report Share Posted December 13, 2005 For future reference, I'd like to dig a little deeper into the ASPI issues in general as related to Retrospect. You mentioned 6.5 will use ASPI by default if installed and available. Does that apply to 7.0 as well? It appears to me the so-called NT pass-through is actually the default ASPI provided by Windows O.S., automatically loaded upon recognition of the drive device. Nero diagnostics refer to it as "System ASPI" as opposed to Nero ASPI. Am I understanding correctly? Does Dantz have in-depth articles published on ASPI best practices, tactics & strategies as related to Retrospect? Link to comment Share on other sites More sharing options...
natew Posted December 14, 2005 Report Share Posted December 14, 2005 Hi No. Retrospect 7 now only uses ASPI if you select it in the Retrospect preferences. I believe your explaination is correct. ASPI and NT Passthrough are just different ways of looking down a bus at devices. NT passthrough should work on all systems but sometimes that isn't the case. Then you need to try ASPI. This is all very low level stuff. Beyond using one or the other there isn't much else to know. Thanks Nate Link to comment Share on other sites More sharing options...
