Guessing you need a new hard drive. Shame you didn’t ask before formatting may have been able to rescue your recordings using the custom firmware available for this model.
Even without the Custom Firmware a HDR-FOX-T2 has a FTP server. Using a PC with software like FileZilla you could have copied all your recordings to a PC for safe keeping.
It’s a very simple job to fit a new hard drive. After fitting I would install the CF, one of it’s options is a Hard Disk check and repair capability.
I fitted one of these into my HDR-1000S recently.
