Since a few days ago I"m experiencing slowness in HDD. It is a Transcend HDD with 5400 RPM. That HDD 3 - 4 years old and 4267 power-on hours and 1605 power-on count. I am using CrystalDiskInfo software to check the HDD status and currently, it is showing status as GOOD. But when I am using the HDD it is very slow. I am very much frustrated now if there is any failure or will be any failure soon or in future. So I would like to know how serious is this problem and is anything wrong with the values shows in the CrystalDiskInfo. I am attaching a CrystalDiskInfo status image. Anybody can help me? Thanks in advance.

CrystalDiskInfo is labelling the disk as "Good" because it has no bad sectors.

However, the Read Error Rate is 83.

The counter is described as:

Read Error Rate S.M.A.R.T. parameter indicates the rate of hardwareread errors that occurred when reading data from a disk surface. Anyvalue differing from zero means there is a problem with the disksurface, read/write heads (including crack on a head, broken head,head contamination, head resonance, bad connection to electronicsmodule, handling damage). The higher parameter’s value is, the morethe hard disk failure is possible.


This is a critical parameter. Degradation of this parameter mayindicate imminent drive failure. Urgent data backup and hardwarereplacement is recommended.

My conclusion: Your disk is aging and replacement is advised before itfails. The slowness may be caused by read error and retries, which domanage to finally recover the data (so no unrecoverable errors).
