Forum Question: External hard disk cannot detected on mac

Hi, my hp 1 tb hard disk cannot detected on my macbook pro. I found out that after i plugged in my hard disk and pendrive(4gb & 8gb kingston)into Windows, i can’t detect my hard disk and pendrive on mac anymore. Can anyone help?
By the way, the hard disk had been changed to MS-DOS(FAT)format before this happened.

    Does it show up in Disk Utility? Use that to see if it shows up — it should. And then select it and try to mount it from Disk Utility. Check there too to see if it really is FAT32 format.
