The value is 1, not 99 or 99,7.

Take a look at power on hours "current" is showing 99, "data" - 1. Same with temperature (+71C lol!), on/off count and others. Always read "data" column.
You need to learn how to read S.M.A.R.T. readings before acting like a rude know-it-all. The data field is the actual number, the Current and Worst for most fields are a percentage of the life or how close the value is to the maximum. In the case of the temperature, it is how close the drive is to maximum operating temperature.
In the case of this drive. 1 Power on hour has dropped the total life below 100, so the current and worst are read as 99%, the drive has 99% of its POH time left, that number will continue to go down as the drive is left on. The same is true for Power on Cycle count and lifetime writes.
The temperature reading is a little different. This value is how far away the drive is from reaching 100% maximum temperature. So if the data is 21, then it is 79% away from the maximum temperature. Because the worst is listed as 58, that means at some point the drive heated up to 42% of the maximum. Probably during the long process of cloning from the old drive. The temperature data field is not a degree number, it is the percentage of the maximum temperature allowed. Think of this field like how on die CPU temperatures work. The readings are not direct temperatures, they are percentage of a maximum temperate(Tjmax). The higher the number, the closer you are to that Tjmax. But if the Tjmax is only 85°, and you are getting a reading of 50, that isn't 50° it is really 42.5°.
And just because I know it will be brought up, the Threshold field is not the maximum. That field is a "Warning Threshold". When the value reaches the Threshold the S.M.A.R.T. status will change from ok to warning, but not to bad. The drive will continue to function normally, but the value is getting close to its maximum.
I was refering to the "Current" column because it is the one that tells you the remaining life for those parameters
Other disks I have didn't dropped to 99 until more hours of power.
Newtekie's post makes sense
A lot of drives don't even have limiting values for most of the fields, so they always stay at 100. Samsung is pretty good about S.M.A.R.T. data, they use is properly. So they actually put numbers in those fields, so the S.M.A.R.T. data can give you a rough idea of the lifespan of the drive. The downside is, of course, that Samsung is just making educated guesses on the lifespan, so the drive could really last a lot longer. Those fields could read 0, and the drive might still function completely normally, except it will start giving a S.M.A.R.T error. Mushkin even had a somewhat famous issue with their drives where they set the POH maximum field way too low, to something like 200 hours instead of 200,000 on some of their drives. So they would start to give S.M.A.R.T. errors after a very short time in use. I had a whole batch of these drives that I had deployed to clients. Luckily they fixed the problem with a simple Firmware update.
