New SSHD Fails Seagate ShortDST - Drive damaged?

[NadiaR]

I'm going crazy trying to figure out whether my new hard drive is bad. I have run a number of tests with conflicting results. I'm hoping the community here can help me figure it out. I'll try to describe my process:

My old WD laptop hdd started having bad sectors so I just replaced it with a new Seagate SSHD two days ago. I had an image backed up, ready to be written to the new drive, but I had trouble cloning the drive both with Reflect and Acronis True Image. Both reported write errors. I then decided to format the drive and run chkdsk. Windows failed to format it. Chkdsk claimed it didn't have space to replace the bad sectors. So far I had been using a USB enclosure for the SSHD. I decided that despite the errors, I would insert it into the laptop, boot from it and run further tests without the USB connection.
Windows did boot without any visible problems. Then I spent all yesterday running more hard disk tests. First, I used SeaTools to test it. ShortDST failed twice, but SMART, Short Generic and Long Generic all passed. Beyond the first two times, ShortDST did not fail again. Tried maybe another ten times. Chkdsk reports no bad sectors with /r . HD Tune Pro Trial reports no errors. The only concern there is that the benchmark shows sudden dips and a minimum speed of 3.4MB/S.
I contacted Seagate technical support about the ShortDST fail. They told me to run the Long Generic Test and get back to them. But the Long Generic test passes ....

can you detail the old HDD, laptop and new SSHD specs? (or model nº)

Thank you for answering. The old hdd was a 1TB Western Digital Blue 5400rpm (wd10jpcx-24ue4t0).
Laptop is Lenovo Ideapad Z710. That's an i7-4700MQ with 12GB of RAM.
SSHD is a Seagate 1TB with 32GB Cache 5400rpm (ST1000LX001-1EM164). Was hoping the SSHD would give me a bit more speed while letting me keep all my data.

if there are no problems running windows or other OS, then you may have get a false test result. if the drive realy have some kind of problem, you will see BSOD.

One thing i don't like (but is a personal thing) is the mix of SSD with HDD = SSHD. For me i use a pure SSD on my laptop with an internal HDD for storage. because some laptops may get problems with mix SSD+HDD and if the SSD part of your SSHD disk fails, no more juice.

Thanks again for your answer. No, I haven't had any BSODs. I will assume it's a false test result then, make regular backups and keep an eye on it for now.
I didn't realize you'd lose the whole drive if the SSD part died. I had considered a small SSD internal and an external for storage, but thought that SSHD was a nice balanced solution.

if you don't use your DVD drive, you can put in an adapter to make it a HDD slot.

Oh what an interesting idea! Will look into that

I dont like SSDHD , SSD has a limited TBW (tera byte writes) which means after it reaches the TBW will stop working ...

Never Get SSDHD drive , if you want to cache the drive , GET SSD alone and HD and use a disk caching Software .. in this case , when the SSD dies , the HDD will still work.

Try this : dont use any Imaging program , Install a Clean Windows on ithe SSDHD and see What Happens .. If it works smooth , just Install your drivers / old programs , and copy the DATA files you want from the Older Harddisk.

Thanks Samer for the advice. I mainly used imaging because I wanted to bring over the recovery partition, etc. I'll try a reset of windows 10 and see if that makes a difference. I wouldn't have thought windows would affect the Short DST test though. I could be wrong.
