How can I get data from a damaged external hard drive?

Q. I have a 250gb I/O Magic external drive that seems to have a damaged USB port. My computer recognizes the hardware when I plug in the USB but it rarely sees the drive letter. Sometimes it shows up in "my computer" but it doesn't stay there. It also freezes up my machine when it is connected but everything returns to normal once I unplug the USB cable. Any ideas?

A. You can still get the data off of the drive it just may be a little more complex because some drives run a linux backend that controls the partitioning information and makes recovery a little more difficult. First you need to determine if it is just the USB port that is damaged or if the HDD is physically failing. Visually inspect the port on the drive and see if it has bent pins or if it is loose. If the port is damaged you can usually take apart the drive enclosure and remove the drive and hook it up to the bus on your computer. After you have the drive hooked up you can run some data recovery programs like Recuva or you can go to ontrack.com and they have some trial software that will look and see if any of the data is recoverable. If the drive is physically failing you may have to send it off to a clean room to have the data recovered which can be really expensive. Some of the drives I have sent to recovery have been over $1000 to get the data back. If you determine that the drive is failing and is still in warranty, I would call the manufacturer of the drive to see if they offer any sort of discounted recovery services. Good luck!

i have accidentally clicked on delete on a volume, but unfortunately without realizing it will delete the other mirror volume as well. i am wondering is there any quick way to retrieve back the other volume without going through the data recovery route? the volumes are dynamic disk and running on win7.

A. You can try Runtime RAID Recovery for Windows. It support both Hardware and Software RAID.

How to format flash drive without erasing data?
Q. All of my IMPORTANT data is on my flash drive. And all of a sudden it is saying that I have to format it in order to use it. When I go to format it is says that it will erase everything on the flash drive to format it. How can I avoid losing all of my data.

A. Formatting WILL erase all your data.
Try the drive in another machine, if it works, it's your computer that's faulty.
If that's the case, try this on your computer...

First try unplugging (and removing the battery on a laptop), press the power button for five seconds. Leave it for two minutes and try the USB again.

If that doesn't work, remove all USB devices....

Restart in Safe Mode*

Open Device Manager, click Start, and then click Control Panel. Double-click System. On the Hardware tab, click Device Manager.

Double click 'Universal Serial Bus Controllers'. Right-click every device under "Universal Serial Bus controllers", click Uninstall and click OK for each instance. Don't worry, Windows will re-build them.
Restart normally and try again.

*Note: On start up (before Windows loads) keep tapping either F5 or F8 (be aware that some manufacturers use F8 for system recovery!) then use arrow keys to highlight 'Safe Mode with networking' and hit Enter/Return, click on a user account, enter the Administrator password (if you don't know it, there probably isn't one so leave it blank) and hit Enter/Return.
