External hard drive to internal - where is my data?

Hello,

I have a WD 1TB external hard drive. The prong that accepts the mini-usb broke so I wanted to salvage the data on the hard drive and transfer to another HD.

I removed the parts that made it mini-usb accessible and plugged it into my computer.

It does not show up under Hard Drive Disks - and when going under computer management (compmgmt.msc) it recognizes it as 'Disk 0' and says that 931gb is unallocated and I can format it.

Is there anything I can do to access the information on this HD?

Thank you

p.s. it is connected internally through a SATA drive and has power

 

Will it let you assign a drive letter?

 

It did not prompt me with anything like that, nor could I find any option

 

computer management-disk management-right clik on drive assign drive letter under change drive letter & paths it may be necessary to initialize the disk first this is done in the left column where it said disk 0 or whatever disk it is
