CrystalDiskInfo Warning

[Euchrestalin]

I recently installed CrystalDiskInfo on my computer. Its primary purpose was to see how my new SSD was behaving. However, it brought up some strange warnings for my Seagate 7200.11 1.5TB hard drives. Two of the drives have caution warnings. When I looked at the information for all three drives the only thing that stood out to me was a yellow by "Reallocated Sectors Count." However, the readings on all three drives was the same (despite only two drives having warnings). Does anyone have an idea why this is?

Press F6 (Rescan) a few times to see if it changes. I've heard that C.D.I. sometimes can read things wrong.
With my two Hitachi 2TB drives, one says "Unknown" and the other one says "Good". I then have to F6 rescan about 2-3 times for it to show the 1st drive as "Good".

You should also download the Intel SSD Toolbox program, it shows SMART errors as well, even for regular HDD.

Note the numbers. Run chkdsk /r and/or other "sector scanning" software several times on the drive to cause it to touch the entire disk surface area with read/write operations. Check the SMART data again. If the reallocated or pending sector count continues to change, throw the drive away.

The raw value are different, and should be providing a count of how many sectors have been reallocated. 0A and 13 suggests that those drives have 10 and 19 sectors reallocated respectively.

For what it is worth, once the HD starts doing reallocated sectors errors, it is best to RMA the HD.
While I know that you can reformat the HD and that may "fix" the issue, it still is a bad sign, and all my HDs that started to do reallocated sector errors have all failed completely.

Run SeaTools on those drives. I've had two 1.5gb Seagate drives fail in the last 6 months. Just sent one back for RMA. Stresses me out that I only have the back up drive as the source for the data. One day I will have a third set for my data. Of course that means I will have to get 20TB of HDD space.

I've had some ST9250421AS drives I get at work quite a bit that are famous for bad pre ver HP87 firmware problems. Drive will suddenly start running 10x slower, taking 40 mins to boot XP when before it only took 5 minutes, disk light solid all the time, etc. and will act like a dying drive and even show massive sector reallocation.

I experimented with one with the dodgy firmware which showed thousands of reallocated sectors and was just a complete dog showing all the symptoms of a failing HDD. Updated firmware, which reset the SMART logs, then ran numerous sector by sector read/write diagnostics on it for a day or two and not one reallocation event recurred. HDD was perfectly fine and ran like a brand new drive.

I'm suspicious that both your drives are the same model and same firmware.
