The partition on my 250gb Seagate FreeAgent Desktop has been corrupted. Am I able to recover the data on it or is all hope lost . (Complete noob here) I have tried using chkdsk but it didn't work.

Actually I am not sure if a corrupt partition is the problem. Can someone confirm by looking at this screenshot?

Thanks for the help.

If u hdd its fully detected by BIOS, Model, SN, etc, maybe looks like a File System File damaged, if u has winhex u need to check, on first partition table structure, then, check the Volume Boot sector, check if its FAT or NTFS, check the FAT clusters or, then check the MFT (Master File Table) the most important records, and after that u need to calculate the link to the data if its OK, all informartion MFT if its correct the link or are some incorrect parameters, at some times occours damaged on the MFT, could be on 00h or some times are overwritten by another "code" Music, interte files , etc we had check this on cases when the user use an simple HDD like a "Server" on a Windows System
