Ok straight to the point. I have a WD 750GB portable hard drive. About 6 months ago, I stored a PC backup to this hard drive, I also had about 500gb of movies and the like stored on it. I tried to move something from the hdd to my laptop, it didn’t work and ever since then, this hard drive isn’t working. I have a new laptop now and I thought I would plug it in on the off chance it might work (I had previously given up on it) now I NEED more storage space, I plugged it in, it automatically installed the drivers and such as per usual, but the autoplay window never popped up, so I went to “Computer” and the disk wasn’t even listed there. Then about 5 minutes later, a window popped up saying “You must format this disk before you can use it” I cancelled that and went to Computer again and the disk was listed this time, but not as a removable storage device, it was a “local drive” so I right clicked on it to check the properties and BAM, everything froze (this is exactly what happened on my old laptop and what caused me to stop trying to resolve it) Also, if I “format disk before I can use it” the format just does nothing, it will run for hours upon hours or until I cancel it. So obviously the format option isn’t working either.
So I really need to know if there is anything I can do for it? Basically, whenever i plug it in, it does the same thing, it shows up as a “local drive” and I freeze up when I try to right click on it, so basically I can’t access anything from there. Is it possible that I need to change the drive number? as in “C: Drive” (if so, how would I do that?) no matter which port I plug into, it is always Drive F:
Please help, I can’t afford to get a new hard drive, and this would be so useful if I had this running again and would save me about $100 to replace. I have a HP 4gb laptop running Windows 7. I’m not super tech savvy so as much detail as possible would be great thanks.
Any help will be much appreciated, cheers in advance!
