I received your mail too with the image about the current status. I uploaded here for reference, as it may be useful for other users too in similar situation and also it probably helps to understand the situation:
First of all, sorry to say, but I do not understand why do you feel there is a problem with the SSD in general, especially with the "spare" area.
hdsentinel wrote:> As such, what does "spare" actually mean? Is it like a bad sector replacement where HDD manufacturers add should your drive start to fail?
Yes. The spare area is exactly designed for this purpose: when a sector fails, then it is marked as "bad" and all further reads/writes targeted to this sector automatically re-directed to the spare area.
Yes, SSDs can also have bad sectors of course, it is not a "hard-disk-drive only" thing.

Available Spare (Percent) = 100
Available Spare Threshold = 10
Percentage Used = 1
It means that your SSD has absolutely NO BAD SECTORS. The spare area is 100% available, which means that no reallocations ever happened. There are absolutely no issues with it.
The Health decrease is caused by the other number, the Percentage Used = 1, which means that (because the SSD tolerates only limited number of overwrite passes) 1 % health of the SSD already used. This is why the Health value is 99%, even if the SSD is PERFECT (probably this is displayed on the Overview page, confirming that the SSD is in excellent health) as these pages designed exactly to describe the situation, explain that it is completely normal and expected that the health of the SSDs slowly but surely degrade with time: the writes degrade the status/usability of the SSD. Generally it is not rare that from 100 to 99 SSD health go down relatively sooner.

Probably the file was just used ("locked") which is normal: Windows and/or running applications can open and "lock" files while they are open. It is normal if you open a document, image, video file for editing (or just playback) and the opening software is using that file which can prevent further access (or delete).
hdsentinel wrote:Because of this, of course no RMA required (especially if the tests confirm that the status is perfect and stable). The 99% Health is not "evil" and as you can see, the status is still "Excellent".
The Health % decrease just helps us to
- identify if there is excessive writes which CAN quickly "kill" the drive (as happened with some failed Windows update and/or antivirus software, writing 100's of GBs every day and causing excessive wearout)
- identify when the SSD should be replaced, for example if its health is really low (eg. below 50 % we can plan replacement, but it is probably far).
