The hard drive in my HP laptop which is a Western Digital SATA hard drive recently crashed. The operating system on the hard drive was windows 7. After it crashed, when I started it again it said unbootable hard drive. I took the hard drive out of my laptop and connected it to my desktop which has XP on it, using an USB 2.0 to IDE SATA HDD Adapter Cable. I have tried a lot of data recovery software to see if I can get my files back and none of them work. If anyone has an idea or solution to my problem please let me know.
