I ran into something this weekend when working on a friends laptop that resulted from her removing an external hard drive with out properly using the safely remove icon, she told me she only did it 2 or 3 times normally she did use the icon. And once I looked up the error on google I found many many others that had the same thing happen to them and all of them also had an external hard drive they would attach, from all the info and reading I did that was the cause. What happens is you start to get an invalid drive error message, the one she was getting was invalid drive G:\, any time I tried to go to add remove programs I got that error so could not remove out dated programs, any time I tried to install things it gave that same error, so there was no way to try to update or clean out anything. Could not install or remove due to that error. After researching I found a way to go to the command prompt and type in a substitute code and that would let me remove or install programs however upon reboot it was right back, meaning anytime she needs to add or remove she will need to do that command prompt code first, and when I looked in My Computer it showed a G: drive it was an exact copy of the C: drive it was a ghost said it had the exact same volume etc. I tried every thing I found online to try to get it to go away including some registry edits but on hers the registry items were not changed so I could not edit it. So if you do use an external hard drive and you see that you can not safely remove I HIGHLY recommend just wait till you can shut down if that is how you have to do it because you really do not want to have to deal with that ghost drive mess. for those interested the exact error was Error 1327 Invalid Drive G:\ and to make matters worse on her pc everywhere it showed the G: drive it was grayed so there was no way to change that drive letter itself back to C. Really strange but by the google search not very rare.

Grandms - I checked hidden icons and it wasn't there. So I just did it by turning off the computer. Canibus - since I have an on/off switch, if I turn that off, is it sufficient to do that first - then disconnect the esata cable? I did unplug it - but may have turned it off, disconnected from pc, and then unplugged power. These are such important things - the order of shut down and disconnection. It's something I never thought about until very recently - and several people I've talked to since had no idea about the safely remove hardware button - or the order of disconnecting,powering down an external drive. The people I talked to just unplugged the drive - and so far they've been very, very lucky. When I reconnect the ext. drive, just want to be sure I have the order correct: computer off connect external drive to power adapter and plug it in connect esata (or usb) cable to computer turn on the hard drive (or do I turn it on before connecting to pc?) turn on the computer I'm asking bc. I just got an external drive for my daughter's computer and the instructions don't say anything about whether the computer has to be off or on before connecting the ext. drive. Thanks. Lynn.

I would certainly use an external hard drive for back ups. In fact I have just swapped my hard drives around to do that. But it will be for an Acronis image of each of my 3 computers, not necessarily for personal data. Although that might also be done. Besides my backup images of the other drives I keep up to date anti virus, firewalls and spyware programs on my external drive so if friends get into trouble I have those programs at hand to install if they do not have then already.

Dee can - Please DO NOT trigger a Format. It deletes everything on the drive (including Windows). If you reformat your PC's hard drive, it'll be useless to you and won't start again until a new operating system installation is done. It shouldn't be something you need to do. raven - I disagree with your suggestion about the advisability of having a HDD image. Use of same would seem to be well beyond the ability of most people who visit this forum. To avoid problems and inconvenience, my first suggestion is that everything important should be backed up and, correspondingly, unimportant files needn't be backed up. Many users have nothing but unimportant files. A simple emailer and web surfer likely has nothing that needs to be backed up. My second suggestion is to avoid problems by using proper tools and practices. (Many of the tools and practices I've seen recommended in various threads in this forum I don't agree with) My third suggestion - if a problem is encountered that the user doesn't know how to deal with, find a service provider or someone knowledgeable to help you. For "seasoned citizens", younger family members may be useful for this. Write down on a piece of paper (yes, a piece of paper) the programs you use and the obscure websites you like and have bookmarked. Other than important data files (photos, music, correspondence), EVERYTHING ELSE on your PC can be reinstalled, re-downloaded, and otherwise replaced. If your PC is old, struggling, or otherwise deserving of a proper burial, buy a new one. They're cheaper than ever, and old your old PC may not be worth the cost or effort to resuscitate. Good luck to all. With a first rate antivirus program, all that's left for you to do is to know where you go and know what you open. With that and absent being very unlucky, you won't have any problems.
