S.M.A.R.T. hard disk status and hard disk failure prevention

Almost every EIDE or SATA hard disk includes S.M.A.R.T. data. That information is collected by the drive itself and contains data that the manufacturer considered relevant to check reliability. The data is made up of several attributes that have a current value, a worst one, a threshold, some raw data, and some flags. Basically, when any attribute's current value is below its threshold, the hard disk is considered unreliable and likely to fail. By using several techniques, this report tries to give a wider range of info, basing its analysis on advanced comparisons with normal values based on real hard disks and on expert-like checks. The final results are not to be taken as an absolute truth, but they are a very good approach to what a professional would say about your hard disk status.

Your hard disk is a ST380011A with firmware 3.16.

Your hard disk's S.M.A.R.T. attributes are now being analyzed and a full report about the reliability, health and status of your hard disk is generated:

Your hard disk is now being compared to real data used to define normal values for your specific hard disk model. This way, the analysis can automatically use proper operating ranges. The images give you an idea of how each attribute is within such range. Current and raw values are shown for easier reference for experienced users. There are 2684 hard disk models in the current archive.

	Attribute	Current	Raw	Overall
	Raw Read Error Rate	64	93801976	Good
	Spin Up Time	98	0	Good
	Start/Stop Count	100	88	Very good
	Reallocated Sector Count	100	0	Very good
	Seek Error Rate	88	794268360	Very good
	Power On Hours Count	63	33151	Watch
Warning: Power On Hours Count is below the average limits (88-100).
	Spin Retry Count	100	0	Very good
	Power Cycle Count	100	911	Very good
	Hardware ECC Recovered	64	93801976	Good
	Current Pending Sector	32	37552	Watch
Warning: Current Pending Sector is below the average limits (100-100).
	Offline Uncorrectable Sector Count	32	37552	Watch
Warning: Offline Uncorrectable Sector Count is below the average limits (100-100).
	Ultra DMA CRC Error Rate	200	0	Very good
	Write Error Rate	100	0	Very good
	TA Increase Count	100	0	Very good

NOTE: not all warnings are reflected on fitness and performance overall values as relevancy is based upon the settings from the hard disk manufacturer who is the best entity deputed to define such relationships.

NOTE : your hard disk has 37552 pending sectors (this value is very large and your hard disk should be replaced). Those are sectors that couldn't be properly read and that the hard disk logic is waiting for a write operation to try to remap to a spare sector (if available). According to the Reallocated Sector Count attribute, your hard disk seems to have available spare sectors. A simple disk surface scan won't be enough to force the remap operation. You need a read/write surface scan to remap the sector. The best option should be a tool that knows about what should be read from that sector so that it has some option to apply the best fix to the missing data.

NOTE : your hard disk has 37552 offline uncorrectable sectors (this value is very large and your hard disk should be replaced). Those are sectors that an offline scanning found as unreadable. Offline scanning is a process that can be automatically started by the hard disk logic when a long enough idle period is detected or that can be forced by some tool. Those unreadable sectors are identified and the hard disk logic is waiting for a write command that will overwrite them to try to remap them to spare sectors (if available). According to the Reallocated Sector Count attribute, your hard disk seems to have available spare sectors. A simple disk surface scan won't be enough to force the remap operation. You need a read/write surface scan to remap the sector. The best option should be a tool that knows about what should be read from that sector so that it has some option to apply the best fix to the missing data.

NOTE : your hard disk Power On Hours Count attribute current value (63) is below the normal range (88 - 100) reported for your specific hard disk model. Basically your hard disk was powered on for more than the maximum time the average user did. This means that either all of the reports collected are from hard disks that were not powered on for too long (this is realistic for recent models) or that your hard disk is becoming old. Usually this is not considered as a pre-failure advisory, but you should check whether you want to replace the hardware or keep an eye on its performances over time.
