Today I bought a Samsung HDD S-ATA 2 500 Gb 7200 RPM 16 Mb Buffer with 3 Gb/s transfer rate and I was very happy I finally got a good and quiet HDD to download torrents from private trackers and making a hell of a ratio.
Though I knew that my MB Asus K7Upgrade-880 supports only S-ATA with 1,5 GB/s transfer rate, the guy at the store told me that the HDD can be switched to 1,5 Gb/s transfer rate so my MB can accept it by mounting a jumper.
So I he cooled me off with this argument and so I bought the HDD.
But when I got home, the hell unleashed upon me!
First of all, I couldn't find anywhere how to set the jumper to make it running at 1,5 Gb/s!
After this issue, I mounted in my PC thinking that the MB maybe can recognize it easily [the MB has 2 S-ATA slots, one occupied already by my brother's HDD which is S-ATA 1 and works fine]. But, for my nerves, the damn HDD wasn't even screened at the beginning of loading the system [the first lines where you are shown all the connections], only the HDD of my brother. When I entered Windows XP SP 2, the HDD wasn't recognized. I restarted, entered my brother's Linux Ubuntu and the same problem there.
I thought to disconnect my brother's HDD which is S-ATA 1, and try to enter Windows without it. Still no recognized...
I entered CMOS (BIOS), cuz the help book which cam ewith the HDD so was saying. Here I couldn't do too much [old and simple BIOS].
Finally, I wondered if my new and cool HDD

would work through my External Rack HDD Connection. And of course it worked...
Well, I said that I'll use this way till I will upgrade my PC and take a better MB which recognize S-ATA 2

So, I made my partitions, copied my files [lots of files ] and I was happy.
But my happiness didn't last too much. When I was in the middle of copying some files, Windows [''Bill Gates' retarded system'' as my brother, fan of linux, names it

] prompted an error [something like write failed and bla bla bla], followed by te sound of USB external device disconnection.
I wasn't too worried about it - I said to myself that it's a glitch and it would finally work. So I connected my HDD again - but, what do you think it happened?
WINDOWS COULDN"T SEE THE HDD!!!!!!!!!!!!!!!!!!!
So I've entered driven by desperation in the Partition Master and guess what?
ALL MY PARTITIONS WERE GONE!!!!!!!!!!!!!
So, now, as we speak, I'm using EASEUS Data Recovery Wizard Professional 4.3.6 to recover my files [what's left of them].
Update: I succedeed in copying 2 of the partitions fully [3rd partition is gone forever ...

] Now I'm using Testdisk [from your site], trying to restore my partitions. If this doesn't work I'll try to use some other programs from EASEUS cuz they seem to be good.
So, in the end, after this blockbuster action packed movie, thanks to Mister retarded Windows and cheating guy from the pc shop, I have no solution of making this HDD working...
So please, tell me how do I make it run at 1,5 Gb/s?
And, if there's no solution for that [yep, I'm gonna blow the seller's head off! you'll see me on news

] at least tell me how to recover the files left on my 3rd partition or restore the partition table. Some programs names would be helpful.
Yours, sincerely,
Noob Kiddo from Dracula City, Romania,
OUT!
UPDATE: It's 2.19 am... Vampires seek for blood here in Transylvania and I'm trying to restore my partitions... I'm lucky I have an axe with me which has garlic on it

] Anyway, the Testdisk sees only 2 partitions too - so now I'll be waiting your holy solutions...
