[SOLVED] Should I run badblocks on a "new" refurbished hard drive?

I recently got a refurbished 3TB HGST Ultrastar 7K4000. The seller claimed it it has 0 bad blocks.

The drive passed both short and extended tests with Western Digital's WinDFT. The drive also passed short and extended tests with GSmartControl.

As a side note, I'm suspicious the seller may have reset the S.M.A.R.T. data. The LifeTime(hours) seems to have been reset. It was 0 when I got it, but at some point it was 43,780 (which would mean roughly 5 years of on time). Am I reading that right?

SMART Extended Self-test Log Version: 1 (1 sectors)
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Extended offline Completed without error 00% 50 -
# 2 Extended offline Completed without error 00% 9 -
# 3 Extended offline Interrupted (host reset) 90% 2 -
# 4 Short offline Completed without error 00% 0 -
# 5 Extended offline Aborted by host 90% 0 -
# 6 Extended offline Aborted by host 90% 0 -
# 7 Short offline Completed without error 00% 0 -
# 8 Vendor (0xb0) Completed without error 00% 43870 -
# 9 Vendor (0x71) Completed without error 00% 43870 -
Can you do that? Is that common practice? I'm not incredibly knowledgeable about S.M.A.R.T.

So far this seems pretty good. I still haven't formatted or written anything to the drive. I'm wondering if I should run badblocks on it before I really start using it just to be extra sure everything is good. However, I imagine this would take days with a 3TB hard drive.

Any thoughts? Is running badblocks a good idea or just overkill that will unnecessarily stress the drive? Is there a smarter way to run badblocks beyond the default settings? Is there another free tool that will provide a more extensive test then WinDFT or GSmartControl?

Thanks.

Log entries #8 and #9 refer to Vendor Specific SMART commands (B0h/D4h, B0h and 71h). I don't know what these do, but there may be some clues in Niagara.

Also see pages 280 and 452 of the ATA Command standard:

It does look like someone reset the SMART attributes. It might be interesting to try those same vendor commands using HDDSuperTool or MHDD, but the results could be unpredictable and potentially destructive.

Where have I heard og HGST before ?

Yes - Dumpster diving. I beleive those particular disks are common inside tv decoders with recording capabilities.
A speculative guess is that seller have gained those drivers from some equipment that was in store but never actually sold.
