Hi,
Data on my external USB disc My Book Live 2 TB are not accessible anymore. In Windows Disk management utility it appears as "1862.98 GB RAW" now.
I run a quick test and you could find the result below. Do you have any hints how to proceed?
Thanks a lot for your support!

Check the harddisk size: HD jumper settings, BIOS detection...
The harddisk (2000 GB / 1862 GiB) seems too small! (< 4397 GB / 4095 GiB)

Re: External USB disk recovery
Thanks a lot for increadible fast reply. It works, that's great! Going to donate TestDisk .
Re: External USB disk recovery
Hi,
I am opening similar issue once more. I have another not accessible external disk. Once I run Analyze I am getting a log copy-pasted below.
Should I follow the same procedure as previously? i.e. "Try TestDisk, Advanced, Boot, RebuildBS, List. If you can see your files, choose Write, confirm, Quit and restart your computer."
Thanks a lot for your support in advance!
Best regards, Jiri
