Should I reformat a hard drive before using a data recovery program?

Q. My old hard drive is corrupted and I want to salvage the files on it using a data recovery program I've downloaded. However getting the program to read it is difficult. Do I need to reformat the hard drive? When I go to reformat it says this will erase all data on the disk, but according to other websites I've read it should be fine and I should still be able to salvage files. Which is correct?

A. If you do a full format, all the data on the disk will be overwritten with the formatting data - and you will lose the data you want to retrieve.

There is a type of formatting called "quick format" but that erases all the folder data, and that means you will have even more problems finding the data you want.

You say getting the program to read it is difficult. If the hard drive is failing, then you will have enormous problems getting any program to work right.

If the only problem is corrupted folder structures, then a quick format *might* work to erase all of the corrupted data, leaving the other data. Then your data recovery program would have to scan the entire hard drive.

I use the free Recuva program from Piriform to recover data, but I don't know how it would work in your situation. Recuva has the ability to scan all the hard drive sectors, it is an option. If you can get it to work, you will need another drive to have a place to copy the selected data.

There are programs available that will read the data directly off the sectors of the hard drive and present it in hexadecimal format, but that doesn't mean you can make enough sense out of the data to be able to recover it. The better programs also cost money.

What are some good companies to recover data from hard disk?
Q. I need a data recovery from my SATA hard drive that failed. Can't get data back. Had a recovery, but some important (sentimental) video files were not on recovery. I think it's still there on the failed disk that I removed but kept.

Question is, are there any reputable companies that I can send my disk and have them recover all the data on that disk? Especially pictures and videos. I figure it'll cost a lot, but I want the data if it's still there.

Thanks for any advice.

How can I retrieve pictures from my failed hard drive?
Q. We have a dell computer that is 3 or 4 years old. It has a Western Digital hard drive. It is at a PC repair place now, but so far they have not been able to retrieve any data. They mentioned the possibility of sending the hard drive to data retrieval place, but said it would be very expensive. He is still working on it now though. Anyone have any other ideas on how to retrieve our data. The most important things to us are our pictures and i-tunes library and some excel spread sheets, but of course ideally, I would like to get everything to a new hard drive. I read something on the internet about freezeing your failed hard drive for about 24 hours, then apparently after freezing it, it could work for as long as 20 minutes when you take it out. Anyone ever heard of such a thing? Thank you!!

A. Freezing the hard drive can help in a few unique cases. I wouldn't bank on it though. Chances are if the local shop can't get the data with the ususal recovery software. Sending it out will be your only option. These places usually rebuild the driver around the existing platters. Provided the platters haven't been striped. Yea, it's expensive, how much is it worth to ya?
