My son has a Dell Inspiron 5150 that is having some problems. It won't boot up at all. Sometimes when it tries to boot up, it goes to a black screen with the cursor flashing in the upper left hand corner. Other time it makes it to the log in screen, then after you log in, it locks up. I'm kind of thinking hard drive. My wife has a Dell Latitude 610 and I was wanting to try her HDD in my son's laptop to see if it actually is the drive, or if we have other problems. My question is are they compatible, except for having to change the bracket that mounts it into the computer?? If so, I'll give it a try, if not, I need to find another alternative. Then we will have to work on trying to get his data off the original drive. Is there any way we might try getting into a safe mode or anything to try to recover data? Thanks for any help.
