is it very bad for hard drive on PC turned ON for 24 hours

1. could it mean it would die more easily and quickly?

2. Does hard drive dissipate a lot of heat ? 3. Does heat dissipated in other area an issue to hard drive?

Since I've got three internal 3.5" 2T HDD

Hi there brannsiu,

1) I wouldn't say so. The HDD spins down after some time if not accessed in any way.
2) Yeah, they dissipate heat, though if the drive is not damaged in some way, it should be fine.
3) If your system is overheating, it could cause problems to other components as well. So, it is a good idea to make sure the airflow is not blocked in some way.

To sum it up: The HDDs should be fine. Also, it may be a good idea to test the from time to time with a brand specific tool and examine their S.M.A.R.T statuses.

My current drive (40GB Seagate) was obtained secondhand and has been spinning almost continuously for the past two years. When I got it, it had about 50 reallocated sectors. Now it has 58.

My previous drive (a 20GB Fujitsu) was also in continuous 24/7 service for many years before I stopped using it. It has no defects. Neither drive has any bearing noise, although the Fujitsu has always vibrated.

That said, I don't have any recent models that are in working condition.

hi how to examine their SMART statuses??? does it need any software to do so ?? thank you very much!!

Most of the HDD manufactures have their own testing tools. The results will provide pass or fail grade as well as S.M.A.R.T report where you can eventually observe whether there are some bad sectors on the drive(or something else abnormal). Third party testing tools will do more or less the same thing.

The manufacturer's SMART tool usually doesn't report the raw values of the SMART attributes. SeaTools is particularly bad in this regard, since it can give a passing grade to a drive with as many as 2500 bad sectors without even warning the user.

Third party tools are much better in this regard. I would examine the SMART report with a tool such as CrystalDiskInfo.

Look for reallocated, pending, or uncorrectable sectors.

HD Sentinel, smartmontools (GSmartControl) and HDDScan are other good tools, although the latter uses a convoluted approach to displaying the data.
