Hey guys!
I have an HDD here that at first failed the extended test with WD Lifeguard Diagnostic but now it passes.
I'm confused about this and was unable to find an answer. I hope you've got a good explanation for me. 
Details to the problem:
I have a convertible / multimode notebook Medion P2212T. The HDD in the base unit is an HGST HTS545050A7E680 (Travelstar Z5K500 series). A health test with WD Data Lifeguard Diagnostic produced these results:
QUICK TEST: PASS
EXTENTED TEST: FAIL
Test Error Code: 08-Too many bad sectors detected.
Due to the failed test and loads of other problems with the device I sent it in for repair and I got it back yesterday. To my surprise the model and serial numbers of the HDD are the same as before the repair. Obviously the HDD wasn't replaced.
So I checked it again with WD Data Lifeguard Diagnostic. Here's the result:
EXTENDED TEST: PASS
I couldn't believe it and ran the test again – same result.
Could it be that the extended test before the repair didn't actually fail because of the HDD but because another part was faulty? I thought the error code was unambiguous (HDD faulty)?!
Some part was actually replaced – no clue which one though; the repair report is very vague.
Regarding the HDD I had the following symptoms before repair:
So the big question is: Is this drive faulty or not? I hope you guys can shed some light. Looking forward to your opinions.
Thank you!
Jimmy

Regarding the HDD I had the following symptoms before repair:
- 1. HDD was often not recognised when the tablet unit was connected to the base unit.
- 2. If it was recognised it often didn't show up in the file explorer.
- 3. If it did show up I often couldn't access it (loading forever).
- 4. When copying files from the HDD the transfer speed dropped to 0 after a few seconds.
So the big question is: Is this drive faulty or not? I hope you guys can shed some light. Looking forward to your opinions.
Thank you!
