    I just found a SMART drive info reader (CrystalDiskInfo) and tried to see what my hard drives SMART info is stating. My first hard drive status is "Good" but the second one has "Caution" status:

    C7 200 200 __0 000000000000 UltraDMA CRC Error Count

    Since I am not familiar with the SMART statuses, with a "Reallocated Sectors Count" signalling a SMART "CAUTION" status, should I be concerned?

    it could have surface errors or just simply few bad sectors, etc.....

    Run a chkdsk on it, see if you get any errors and fix them. Also formatting the disk (NOT with the "fast" method") might get rid of the errors.... if they are not surface errors....(bad clusters)

    Also, download hdd tools from hitachi and run extensive tests on the disk so you know if the disk it's ok or not. Usually all vendors have nice diagnostics toools that would tell you if the hdd it's defective. Take caution since some of those tests can destroy the data you have on the disk

    Also, re-do all your wiring check cables, etc; install latest chipset drivers..... just to make sure.

    47C it's a bit high on my book, tbh.......

    Be weary of some errors that may be generated by the hdd diagnostic software....some can be caused by faulty SATA cables. Love WD's "Data Lifeguard"....I've had it declare a few harddrives faulty, just to find out the cables were the real issue. Avoid using options like "Write Zeros to drive"....or "Perform Zero write" or "Writes 1's and Zero's to drive"....those are destructive formats. Some manufacturer's consider them "low-level" formats, which they're not. Some manufacturer's even list an option for "Perform low-level format". A true "low-level" format is not possible as it requires direct read/write access to the harddrives internal controller and can in fact destroy the harddrive. If you run Hitachi's diagnostic utility and find "bad sectors" that can't be repaired by simply running chkdsk, the next time you format you can use the "low-level format" option or "write zero's to harddisk" option which in some cases can repair bad sectors.

    Windows XP and newer will check for bad sectors before writing any data so you don't need to ever worry about performing a surface check. Just check the S.M.A.R.T status/report once a month for any major anomalies in disk health like a huge amount of bad sectors.
