Active Hard Disk Monitor Raw Read Error Rate
Contents |
Attributes Each drive manufacturer defines a set of attributes and selects threshold values which attributes should not go below under normal operation. Attribute values can range from 1 to 253 (1 raw read error rate fix representing the worst case and 253 representing the best). Depending on the manufacturer, a

S.M.A.R.T. attributes in various products include: Samsung, Seagate, IBM ( Hitachi), Fujitsu, Maxtor, Western Digital. These manufacturers do not necessarily agree on precise attribute definitions and measurement units; therefore the following list should be

regarded as a general reference only. Note that the attribute values are always mapped to the range of 1 to 253 in a way that means higher values are better. For example, the "Reallocated Sectors Count" attribute value decreases as the number of reallocated sectors increases. In this case, the attribute's raw value will often indicate the actual number of sectors that were reallocated, although vendors are in no seagate raw read error rate way required to adhere to this convention.

Any number indicates a problem with either disk surface or read/write heads. 02 02 Throughput Performance Overall (general) throughput performance of a hard disk drive. If the value of this attribute is decreasing there is a high probability that there is a problem with the disk. 03 03 Spin-Up Time Average time of spindle spin up (from zero RPM to fully operational). 04 04 Start/Stop Count A tally of spindle start/stop cycles. 05 05 Reallocated Sectors Count Count of reallocated sectors. When the hard drive finds a read/write/verification error, it marks this sector as "reallocated" and transfers data to a special reserved area (spare area). This process is also known as remapping and "reallocated" sectors are called remaps. This is why, on modern hard disks, "bad blocks" cannot be

Manufacture date shows as January 2012 (yes that's as new as new can get), so must be one of the new batches from the post-flood Thailand. Anyway, I downloaded a copy of Active Hard Disk Monitor tool to check the S.M.A.R.T. parameters and I find the parameter Raw Read Error Rate is very low. Should I http://superuser.com/questions/393257/brand-new-seagate-hdd-has-high-raw-read-error-rate be worried? Will this rectify over time? This hdd is just 7 hours old; what gives?

This is just the magic that goes on behind the scenes all the time on a high density drive, and when a user looks at this smart data it scares the hell out of them. –Moab Feb 24 '12 at 17:01 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote It seems it may be a count of the actual sectors read, the errors are in the upper 16bits of the 48bit word, please see http://forums.seagate.com/stx/board/crawl_message?board.id=ata_drives&message.id=25651 On my Seagate drives I have high decimal numbers, but when converted to hex I in fact have 0 errors in a whole lot of sectors read. share|improve this answer answered Jun 28 '12 at 18:52 Andrew 212 add a comment| up vote 1 down vote
information Attribute Name: Raw Read Error Rate Attribute ID: 01 Description: This attribute value depends of read errors, disk surface condition and indicates the rate of hardware read errors that occurred when reading data from a disk surface. Lower values indicate that http://www.ariolic.com/activesmart/smart-attributes/raw-read-error-rate.html there is a problem with either disk surface or read/write heads. Critical: Yes Hard drives that support this attribute: Samsung, Seagate, IBM (Hitachi), Fujitsu, Maxtor, WD (Western Digital) Software that supports this attribute: ActiveSMART, by Ariolic Software Download ActiveSMART and monitor S.M.A.R.T. attributesClick here to learn more about ActiveSMART What is the S.M.A.R.T. attribute?The S.M.A.R.T. attributes are specific properties (parameters) of various parts of a disk. S.M.A.R.T. uses attributes to monitor read error the disk condition and to analyze its reliability (e.g.: the "Temperature" attribute indicates the temperature of the hard disk, the "Power-On Hours" attribute indicates the count of hours in a power-on state, etc.) Various manufacturers may use different sets of attributes. Want to protect your hard drive from a sudden breakdown?Modern hard disks support a self-monitoring technology called S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology). This technology allows you to monitor the important read error rate parts of hard drives, warning you if their condition is getting worse and data loss is possible. However, in order to use this information, you will need special software which can collect and process it. Active SMART is intended for just this purpose.Install Active SMART to protect your HDDs and the data stored on them.
