Hi, I have a 2TB HP simplesave hardrive with tons of movies on it. Yesterday I plugged my laptop (with external hardrive attached) into my television so i could watch a movie from the HDD on my tv. Now when i try to use the hardrive on my laptop alone, i noticed it has change from (H to local disk (I and when i plug it in a pop-up says:

(I: hardrive is not accessible. The parameter is incorrect.

When i click it to try to access the files on it it says:

You need to format the disk in drive I: before you can use it.

And I cant format it because i would lose all my movies!! PLEASE HELPP!!!

It's likely you lost your partition. Does this find it?

Could we see the partition table and boot sector with Microsoft's Sector Inspector?
