My 1 TB external hard drive which currently houses about 850 gbs worth of media is having an issue.

It won't display in my computer but it displays in disk management in black as 931 gb of unalloacted space. When I right click I can't assign it to a drive letter.

When disk management pops up it asks me to intiliaze and that's when i get the CRC error.

I figured it was because of the case so i took the hard drive out its a Hitachi and plugged it right into the motherboard sata style.

Same issue. I googled the error and apparently it means i have a bad area on the disk or some corrupt files.

Im wondering what kind of software tools I may be able to use to recover some of the data or even fix the issue. I would really like to be able to use this drive but if I could atleast get some of the data back that would be nice.

Thanks,
Blimkie
