The Help Desk: Oops -- how to retrieve deleted files

Q: You've explained that deleted files on a hard disk can be retrieved. I have some deleted files on my laptop that I need. I'm using Vista. How do I get them back?

Michael Lawson

A: The first line of defense is the Windows recycle bin. If it hasn't been emptied, retrieving a deleted file is simple. Just click open the bin, select the file you want back and retrieve it.

If the bin has been emptied, it's still possible -- but not certain -- that you can retrieve a deleted file. But you'll need help from a computer program designed to find and retrieve these files. Here's a Web link that offers detailed advice for both Mac and Windows users: http://tinyurl.com/djmtrp.

But, if a crucial file is deleted and cannot be found in the recycle bin it's important to stop using the computer until you've retrieved the file. The odds of that data being overwritten by newly saved files increases as time passes.

Q: I use a DLink Router for a wireless connection to my laptop. At least four or five times a day I lose connection between my laptop and my cable modem. My husband never loses connections using his laptop. What's going on?

Donna Ewald

A: A Google search shows some reports of incompatibility between DLink equipment and a few wireless cards. So -- and all I can do is guess -- your husband's machine may have a card that does not have compatibility problems, but you do.

Start by using your computer on a friend's wireless network or one at work that uses a different wireless router. If the problem goes away, then there's a good chance that my guess is correct. The solution would be to replace the DLink router with another brand such as LinkSys.

Q: The batteries in my old UPS are dead. Which makes more sense, replacing the UPS or keeping it and buying new batteries?

Gary Zeune

A: In almost every case, I simply replace the rechargeable batteries. Prices will vary but, for the UPS I use, that costs less than $50. However, dead batteries provide a good excuse for replacing a UPS if it's given any trouble in the past, or if it the power it furnishes is not quite adequate for the computer system you use today.
