Hi, I use Windows and I have one of these 1 TB external hdd, the story goes like this
1. The drive worked just fine
2. Some few months ago, Windows ask to repair some file when plugged in *i just ignore it
3. Some nice day, i thought of clicking yes, then when I restarted Windows, it booted checkdisk and analized the disk
4. After that, not a single clue, but the disk started to behave funny, it didn-t show on Windows, sometimes it did, I was able to copy some files *its a 1 TB drive
5. I tried fixing it by using TestDisk, which I think broke the thing even more, i don't remember but I think I set it as GPT instead of a normal partition
6. One day I drop the drive from the desk, I don't think anything broke but just stating the facts. *the drive does not make any wierd noises
7. When I plug it in Windows, it appears but without its drive name, just 'Local Disk' and Windows freezes when I try to open it, Linux cannot access it. *in Windows Disk Managment shows as RAW partitioned
8. Booting it with Knoppix and using fdisk -l shows this
Disk /dev/sdb: 1000.2 GB, 1000170586112 bytes
255 heads, 63 sectors/track, 121597 cylinders, total 1953458176 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xf3fc671b

Device Boot Start End Blocks Id System
/dev/sdb1 1 1953458175 976729087+ ee GPT

9. When running Testdisk, it says boot sector is corrupted, and runs too slow. Analizing just brings nothing, also its tooo slow and many times it just stays there, I really don-t know what to do anyway,
10.5 using dd to copy the WHOLE disk takes TOO much time and it renders output drive innacessible too, so its impossible to see the files
11. right now using photorec to recover data and push it to another drive, its slowing recovering something, remaining time is 8860 hours

How do I fix this thing?
 
Solution
SMART doesn't go through USB well. Pulling it out of the caddy and using it internally might work better, though some do some nasty stuff with positioning, so that won't work.

The drive doesn't support SMART, but anyway I did try using speedfan, this is what shows:


"Access violation at address 00674559 in module ´speedfan.exe´. Read of address 00000000."

Your motherboard doesn't support speedfan then.
Have you tested a different cable from the hard drive to the computer.
As the cable could be bent causing slow read/download speeds and the drive to appear and disappear.
