I am calling your help, mighty people who can understand advanced issues of hard drives.
It is not an issue related to HDS, thus the reason why it is in General Dicussion.
A week ago, my Windows 7 would not start properly anymore. It was working fine the day before, then on the next morning, Windows wouldn't boot properly. At first, it loaded to the login screen and then got a blue screen. On second boot, it stucked on loading drivers ("Loading Windows" boot logo). On third boot, I got a Disk Boot Failure error from BIOS. On fourth boot, I was able to log into Windows, then everything freezes and I could hear my main hard drive spin down and spin up. No good...
I then loaded Parted Magic Boot CD, launched GSmartControl (which is a SMART monitoring software). GSmartControl was not able to complete either a Short or Extended Test. I was, however, able to read partitions into GParted. I took the time then to copy all my data to another hard drive, since I was able to read data properly. My data was safe, I was a much happier person !
I then loaded Data Lifeguard Diagnostic for DOS from Western Digital. I was not able to complete either Short or Extended either. Both tests would result in "Missing Tests Tracks" error. I googled that and found some people who had the same issue with the tool in DOS, but no workaround. I was able to test my other hard drives properly, but not this one.
The next day, I fired up Parted Magic again to prepare another hard drive to install Windows and decided to test my defective hard drive again...all SMART tests passed properly. I installed Windows on another hard drive, to diagnose my defective hard drive in Windows with much more tools. I installed HDS and HDS says that the disk is 100% healthy. Both Short and Extended Tests finish without any error and the surface scan shows every sector are healthy as well. Seek and speed tests are fine and what they should be. I am not running anything on this drive, yet. I don't trust it. Western Digital's Data Lifeguard Diagnostic for Windows shows the drive healthy as well.
Should I trust this drive ? Here's the SMART :
1,Raw Read Error Rate,51,200,200,OK,1,0,Enabled
3,Spin Up Time,21,144,135,OK,3766,0,Enabled
4,Start/Stop Count,0,100,100,OK (Always passing),99,0,Enabled
5,Reallocated Sectors Count,140,200,200,OK,0,0,Enabled
7,Seek Error Rate,0,100,253,OK (Always passing),0,0,Enabled
9,Power On Time Count,0,100,100,OK (Always passing),423,0,Enabled
10,Spin Retry Count,0,100,253,OK (Always passing),0,0,Enabled
11,Drive Calibration Retry Count,0,100,253,OK (Always passing),0,0,Enabled
12,Drive Power Cycle Count,0,100,100,OK (Always passing),96,0,Enabled
192,Power off Retract Cycle Count,0,200,200,OK (Always passing),43,0,Enabled
193,Load/Unload Cycle Count,0,200,200,OK (Always passing),55,0,Enabled
194,Disk Temperature,0,114,109,OK (Always passing),29,0,Enabled
196,Reallocation Event Count,0,200,200,OK (Always passing),0,0,Enabled
197,Current Pending Sector Count,0,200,200,OK (Always passing),0,0,Enabled
198,Off-Line Uncorrectable Sector Count,0,200,200,OK (Always passing),0,0,Enabled
199,Ultra ATA CRC Error Count,0,200,200,OK (Always passing),1,0,Enabled
200,Write Error Rate,0,200,200,OK (Always passing),0,0,Enabled
I notice that the Raw Read Error Rate and Ultra ATA CRC Error Count are both valued to 1. I never changed the SATA cable since few months and it was working fine before. It is the same cable as before and seems to be fine. Could it be related to the PSU ? It is about 7-8 years old, but have good values in BIOS (+-10%). It is a (very good) Seasonic
Thanks for any help,
