I got a major problem with my external HDD

I don't see any partitions amymore,
Windows asks to initialise the HDD.

TestDisk tells me Wrong Hard Disk Size and also partition can't be recovered.

I have the same issue. The disk size is detected properly by the BIOS and the OS. Hitachi HDT721010SLA360.

CHS listed on the drive is 16383/16/63

Check the harddisk size: HD jumpers settings, BIOS detection...
The harddisk (1000 GB / 931 GiB) seems too small! (< 1551 GB / 1444 GiB)
