When there is an external HDD attached (WD 500GB, WD 1TB, Maxtor 1TB) ATI 11 sometimes (intermitent error) fails to initialize (have to use Windows task controller to shut down program) OR ATI 11 takes a VERY long time to initialize. The problem is more frequent when more than one external HDD attached. Note there is also a secondary internal WD 500GB HDD (see signature for specifications - and note I am using special ISO supplied by Acronis to work with ICH9 chipset)). Not sure if the problem lies with ATI 11 or some conflict with WD HDD management software - but problem also occasionally occurs with the Maxtor external HDD (which I just bought thinking the problem might be some confusion of HDD controller between all the WD HDDrives). In fact, sometimes windows will not boot up with an external HDD attached and have to boot up with no externals and attach them later. Problem stemmed from time did an ATI 11 backup - though not sure the backup was the cause. Vista windows would no longer boot promptly - or at all - so did an ATI restore off recovery disk. (probably should have tried a Vista widows restore first) - and had all sorts of problems. Error messages about not being able to read Disk 2 (which I would have thought was the secondary internal HDD, where backup was saved), but in process system disk was wiped so computer went into computer shop. Had secondary HDD replaced (under warranty) - though do not understand why corruption in secondary HDD should affect bootup of system - and I restored off new secondary HDD (which had ATI 11 recovery images moved onto them from defective removed secondary HDD). System now working except for some continuing intermittent problems of ATI 11 initializing (see above) AND despite secondary HDD being installed on correct cable (or so says the shop as set as slave), the drives seem to be recognised in a different order. Any listing of drives by ATI 11 lists new internal secondary disk first (as drive 0 or 1) and the preexisting system drive C:/ as disk 2, and second in the list - and then whatever external disk drives that are attached get listed. Also, ATI 11 backups are now about 52GB instead of around 80GB and system drive "used" space is about 30G less than before (but from another thread I see this may just be that all the Vista Windows restore points have been wiped when I restored using ATI 11). I know this is all a bit of a mishmash - but MAY be all related. QUESTIONS: (any advice or thoughts would be most appreciated): anyone else have initialize problems when external HDD attached? Is it relevant or really a problem that internal HDD are now listed in order of secondary drive first? Do I need to redo the emergency recovery disk (using the ISO from Acronis for the ICH 9 chipset) now that I have added another external HDD (the Maxtor 1TB) on which I will also store some ATI 11 recovery points. Does all this indicate some basic computer fault that I should throw back onto computer shop while my 1 year warranty still in effect (for another 3 months)? The shop indicates it is an Acronis software problem for which they have no knowledge or responsibility. Many thanks for any assistance.
