I have a bloody USB Maxtor Personal Desktop External Hardrive with 500G. The partition of it always cannot be read after OS resetting, and windows will prompt to format the partition. Anyone knows how can I solve this problem ?

If I were you I would move the harddisk out and test it with internal SATA connections. This way it's easier for the low level programs to access it and also remove the USB interface from the troubleshooting equation.

Back then when I had corrupted partition tables I will simply recreate it under a software called 'ranish partition manager'.
