This is true, but most of the time the CMOS battery only looses the date and time but will still allow the computer to boot up.Sometimes the CMOS battery goes bad on the motherboard. Some you can replace and some you can't.
We have people call that say "Every page I go to says there is a security problem" and the wife tells them to check the time and date.
Even if the CMOS battery is dead after setting the time and date in windows everything goes back to working normally. (untill the next boot up with the wrong time and date)
The last one I did that with DID have a problem with the hard drive. When I plugged it in the new computer 'fixed' it and was able to recover everything.
My problem now is I have a few old hard drives laying around and no clue what I saved elsewhere. Need to go through everything and organize old files (mostly pics ) in one place without duplicates. Just hasn't moved high enough on the to do list to take time to do it. Only thing I noticed I am missing is some early build pics from the Duster. Think they might have died with the camera or phone I had at the time, or they are on a SD card that is MIA. Not terribly important anymore. Just details I wish I had putting it back together.
I can't tell you how many times a good OS has repaired a corrupted HD file system for me.
And sometimes a drive has a corrupt OS boot file that I can replace using that cable with a copy of the offending file from the computer I am using to access the drive.
