Checking that a SAS drive is good after a controller flagged it as predictive failure?

I am used to using Crystal Disk Info to see about smart status for SATA hard drives

https://crystalmark.info/en/software/CrystalDiskInfo/

I took a SAS drive out of a dell server running OpenManage.  The drive was part of a RAID 6 array. Openmanage was warning of predictive failure.

For the experience / learning curve, I set up a desktop computer with an older LSI SAS controller and the correct cables and can connect that drive / format it as NTFS / read & write to it, etc.

I was curious to see what smart data / statistics of run time, etc  is on the drive / how bad it looks.  But Crystal Disk Info doesn't even see the drive.

Is there another app that can read SMART info on SAS drives... Do SAS drives even have SMART info?  and if not, what's OpenManage looking at to have flagged it as predictive failure?  Just keeps track of the drive as it read / wrote to it over the years? (it IS a 6 year old drive).

So putting it in a new computer / controller, the drive would be considered good? untill this controller starts seeing problems itself?  (the flag that a controller decided that the drive is 'predictive failure' is not transferable to another machine / controller? )

SAS drives do have S,M,A.R.T data but not much software that can read it, https://en.wikipedia.org/wiki/Comparison_of_S.M.A.R.T._tools only lists one and I couldn't find any SAS disks on their website but I may have missed them.

You could just erase the disk and put it back in the old machine if there is a spare slot but almost certainly it will be still shown as predictive failure.

Dell has their own proprietary raid software that works with their controllers and drive firmware.

Crystal is only measuring a generic piece of the drive puzzle.

If Dell says it's going bad ,there must be a good reason.

Try Speccy.  I know it reads SATA SMART status and detail, not 100% sure about SAS but worth a try:

Speccy, like Crystal doesn't support SAS according to the Wiki list.

Realised how to get around the hdsentinel website search for SAS bug (it wants 4 characters and SAS is only 3)

Google sas site:www.hdsentinel.com/

Second link with the list of RAID controllers is quite extensive, they must have spent a lot of time (and had help from the controller manufacturers) in supporting that lot.

SAS drives should show SMART info, that how predictive failure is mostly predicted.
If you have a linux system, try smartctl. (maybe CYGwin has it too?)

but depending on the kind of smart error -  the disk can be used or not (i've been using some for years, without problem
some systems allow to turn of smart reporting

I would not say without problem, the drive is beyond a threshold..., so it should be expected to fail...
so don't put valuable data onit.

Thanks guys!  Some trivia.  It may be obvious to you...pretty new to me -  I'm dealing with SAS and a controller from ebay in a desktop PC for the first time / for the learning experience : )

I ran verify in the LSI controller's system (when you press control c at bootup).  Ran for a couple hours looking at the whole disk.  It said everything is fine!!  (see picture).

I installed hd sentinel and it immediately complained (see other picture).

Interesting statistics - number of hours running,  number of TB of data written. big numbers!  I guess it had a good life : )

Sectors from the spare area get mapped in place of the bad sectors so a surface test won't show them up. Strange that LSI doesn't consider the high number of remapped sectors to mark the drive as degraded, guess they only go by the predictive failure count.

i agree with that...  You can use it as a scratch disk somewhere, not to store something that you cannot afford to loose.

Forgot to mention HPE Smart Array controllers don't flag excessive bad sectors as degraded disk either, you have to read through the ADU report or run diagnostics to see them as bad.
