I've been having a problem lately with my Dell computer sometimes (not always) not detecting either of the two hard drives on my primary IDE channel. The computer is well past the warranty/service period. The problem occurs during the BIOS boot process. Using the BIOS setup screen to reset primary IDE channel drives 0 & 1 to autodetect the drives does no good. The computer seems to either flake out or boot successfully at random. Sometimes, for no apparent reason, it boots just fine into Windows XP. In order to avoid losing data, I wanted to backup what's on the #0 drive onto the #1 drive, but even though Windows appears to function normally when it DOES load, when I attempt to use ATI (V 9.0, build 2259) to backup my data, I get the error message noted above ( E000101F4: ATI has not found any hard disk drives ) Anybody have any ideas why ATI won't function when Windows loads and operates OK? The only thing I can think of is that I was swapping hard drives quite a few times during the process of saving my data files, wiping my C drive clean, clean-installing Windows XP and re-installing my data files before I bought ATI and used it to clone the drive. I'm wondering if all those tugs on the drive ribbon cable could lead to a loose connector/wire causing this intermittent problem. A close inspection of the connectors hasn't shown any visible problems. But even if the cable is at fault, why would Windows access the drives normally but ATI not detect them? Any suggestions would be appreciated.
