I have a Dell Inspiron 17R 7720 Special Edition laptop. It came with 2 hard drives of 1 TB (thus a total of 2 TB). To date, the motherboard has been replaced at least three times now due to (different) defects.
The last motherboard replacement took place about a month ago, where my laptop was sent in for repair in an international repair center (in Germany, apparently).
When I got the laptop, I replaced the primary hard drive myself with an SSD, and kept the other 1 TB drive in it. Worked perfect up until the last repair, where the 1 TB HDD suddenly stopped working after about 15 minutes of usage. I thought the drive simply failed (maybe due to its travel to the Dell repair center), so I replaced it with a spare drive I had laying around (320 GB), and to date, that 320 GB hard drive still works.
So I asked for a replacement drive to replace the broken 1 TB drive, which arrived yesterday. Popped it in, it worked for 15 minutes, and yet again the drive seemed to have died.
I've asked for a replacing motherboard at Dell support now, but I'm curious whether it's actually possible that the hard drive is dead, because the other 320 GB hard drive still works fine.
So, 2 questions:
- Is there any way I can investigate this "broken" hard disk myself before Dell supplies me with a replacing motherboard (and probably another hard drive)?
- Why is my 320 GB hard drive not broken after 15 minutes of use?
For those interested, the 1 TB hard drive in question is a Seagate ST1000LM024.
