This may be of use to someone, as I see I am not alone in having this problem. I have had a lot of problems with failures to recover, and failures to check archives successfully using TI 9.0 home (2337). The PC was 100% reliable (excluding with TI) even with other backup applications, not overclocked, had no RAM faults, no disk errors, no filing system errors and no controller errors. It was an ABIT KT7A, Athlon XP1800+, 768MB RAM running at full rated speed (133/1533MHz). Disks were UDMA100. I could not get consistent results. Partitions would backup OK, check OK, then later, fail to check and fail to recover. And so on. For a backup solution, that is disastrous. When you come to need a backup 'in anger', it isn't much use if it doesn't then work. In the end, the only thing that solved it was to slow up the PC clocks. It is currently running at 100/1150MHz, and I have had no bad checks or recovers since. I assume therefore that the issues are with the PC hardware - clocked within spec or not - not with TI itself. My suspicion is that the backups were really always OK, and it was the check or recovery that failed. Why TI 9.0 finds these problems I do not know. One must assume it is exercising the chipsets - no doubt quite legally - in ways that other applications do not. It would be nice if Acronis could provide a utility to 'stretch' the hardware and thus indicate if reliability is likely to be present or absent. Nonetheless - slowing it up was the answer. If you have this issue - try it.
