Hey all, nice to be here! Hope someone who has experience in this area can give me some advise about my new hard drives. One seems to be a dud, while the other seems OK.
The drives are 2x Toshiba DT01ACA300. They are the re branded Hitachi drives if I remember correctly. Received them a few days ago, and started testing immediately. Software I have used for testing includes:
HD Tune, Hard Disk Sentinel, HDDScan, CrystalDisk Info, WinDFT.
Drive #1 - Suspect Good
*Drive #2 - Suspect 'BAD'
This is the order that the events happened:
1. Did a full 'error scan' test of both drives in HD Tune to find any bad sectors, - both were OK, however drive #2 was 20-25 MB's slower during this test (both on the inner and outer of the disk). This was my first indication something was off. From here, I have focused only on drive #2.
2. Ran a SMART test in all the apps I listed above. All seemed perfect. No bad sectors, everything checked out perfect.
3. My issues begin here. Ran HD Tune 'Random Access - Read and Write Tests' in order to get accurate IOPS values for the drive. Looking at HDD reviews, this test is sometimes performed so I figured it couldn't hurt.... Well. The read test went OK but the write test took almost 2 hours to complete, and the IOPS values were extremely low. This jumped out at me because my WD Black gets at least 100 IOPS (worst). Also the Seek time (ms) is insanely high. At this point - I'm pretty concerned.
Here is a screenshot:
4. Immediately after this, I went to check the SMART values again, and I was shocked. Every program I checked it in confirmed that over 1000 sectors were now bad.
Here are screenshots:
5. I booted up Windows and ran WinDFT (Hitachi drive fitness). I ran a "Long Test" as well as a Short and Extended SMART test - they ALL completed without any error....? The SMART short test shows nothing at all (I mean no entries, no table - just an empty window that popped up). The SMART extended test took over 10 hours to run. My WD drive works fine with the SMART quick test - a window pops up with all the different SMART values. For the Toshiba drive - it's a blank window.
6. I then rebooted my PC - and have been getting SMART error's at the BIOS screen. It says that the drive is about to fail and that it needs to be replaced. I must press F1 to enter bios setup and select boot device manually.
7. SMART tests still show that the drive has over 1984 bad sectors and a bunch of 'relocation event counts".
At this point, I am going to assume the drive is BAD. However, I am a bit unsure what happened because initially when I did the full "Error Scan", it scanned the entire drive for bad sectors, but didn't find any. As soon as I ran the "Random Access Write" test - the drive had bad sectors. Did I break my drive by using this test?? I have seen it used on other mechanical HDD's before so I felt it would be safe to run.
Currently I am running the HD Tune "Erase" tool with the option "Random Fill" and "Verify" option enabled. I don't expect this to help but I am unsure what to do from this point.
I am afraid of running the "Random Access Write" test on the other Toshiba drive (Drive #1 - suspected good), in case the same thing happens....
Please, if someone can give me some advise in regards to where I should be going from here, that would be amazing. And also, whether the "Random Access Write" test killed my drive? Sorry about the length of the post, I just wanted to make it clear as to what I have done/tried.
Thank you so very much for any assistance!
