It lists many of the free and free to try titles. I give the nod to Zero Assumption Recovery but my advice about data recovery is simple. If your files are irreplaceable then you may want to try the titles but consider http://www.drivesavers.com if you can't risk it.
Now that you see the price of recovery can I ask this -> How about a backup copy? Why not a few files you can't lose at your DROPBOX? (see google)
Hi! My external Seagate 1.5 TB Drive recently ceased performing properly. I powered on my Win 7 machine and when it went to load the HD it prompted me to format the drive before it could be used, which I promptly ignored due to having a terabyte of data on there that I cannot afford to lose. I removed the HD from the enclosure and tried another enclosure and it gave me the same prompt to format. I downloaded Seagate Tools and ran scans of the hard drive and it passed both the short scan and long scan. I purchased Norton Ghost 15.0 and Avanquest Disk Utilities to try and recover the data from the drive, however I am having little luck using the programs, due to inexperience in this field. I called Best Buy, Staples, Nerds on Call, and Computers Plus regarding Hard Drive Recovery Service and I was quoted $250-2000. I was hoping I would turn to the good people here on cnet for help and advice before I drop that kind of money on hard drive recovery. I have definitely learned my lesson and have since set up automatic back up. Please any help would be appreciated.
