Migrate Easy 7.0Acronis Drive Cleanser 6.0Acronis Drive Monitor Print 9101: S.M.A.R.T. Attribute: Read Error Rate Applies to: Acronis Drive Monitor Operating Systems: Windows Attribute ID: 1 (0x01) Hard drives, supporting this attribute Samsung, Seagate, IBM (Hitachi), Fujitsu, Maxtor, Western Digital Description Read Error Rate S.M.A.R.T. parameter indicates the rate of hardware read errors that occurred when reading data from a disk surface. Any value differing from zero means there is a problem with the disk surface, read/write heads (including crack on a head, broken head, head contamination, head resonance, bad connection to electronics module, handling damage). The higher parameter’s value is, the more the hard disk failure is possible. Recommendations This is a critical parameter. Degradation of this parameter may indicate imminent drive failure. Urgent data backup and hardware replacement is recommended. More information See also: S.M.A.R.T. Monitoring. Tags:S.M.A.R.T. Was this article helpful? Yes No This is great!Do you have any comments?

S.M.A.R.T. is the abbreviation for "Self Monitoring And Reporting Technology". It is a standard interfaceprotocol and set of the disk features that allowsdisk to check its status and report it to a host system. S.M.A.R.T. information http://www.z-a-recovery.com/manual/smart.aspx consists of "attributes", each one describing some particular aspect of drive condition. Some attributes http://superuser.com/questions/867801/high-s-m-a-r-t-read-error-rate may be designated "life-critical", which implies that the corresponding parameters are more important than other ones. Three values are associated with each S.M.A.R.T. attribute: "Normalized value", commonly referred to as just "value". This is a most universal measurement, on the scale from 0 (bad) to some maximum (good) value. Maximum values are typically 100, 200 read error or 253. Rule of thumb is: high values are good, low values are bad. "Threshold" - the minimum normalized value limit for the attribute. If the normalized value falls below the threshold, the disk is considered defective and should be replaced under warranty. This situation is called "T.E.C." (Threshold Exceeded Condition). "Raw value" - the value of the attribute as it is tracked by the device, before any normalization read error rate takes place. Some raw numbers provide valuable insight when properly interpreted. These cases will be discussed later on. Raw values are typically listed in hexadecimal numbers. Most common S.M.A.R.T. attributes reference Note that not all of the attributes are present on all drives. Some attributes are of similar meaning (just counted differently), so only one of them will normally be monitored by the drive. Some require special sensors (e.g. temperature or G-loads monitoring). The decision about which attributes should be implemented is up to the drive vendor. Along the same lines the interpretation of raw values depends heavily on the manufacturer. Critical device status attributes Reallocated sectors count Indicates how many defective sectors were discovered on the drive and remapped using a spare sectors pool. Low values in absence of other fault indications point to the disk surface problem. Raw value indicates the exact number of such sectors. Current pending sectors count Indicates how many suspected defective sectors are pending "investigation". These will not necessarily be remapped. In fact, such sectors my be not defective at all (e.g. if some transient condition prevented reading of the sector, it will be marked "pending") - they will be then re-tested by the device off-line scan1 procedure and returned

I recently realized that the disk was noticeable slower than before, so I decided to check the SMART data. Everything seemed to be OK. A bit more than a year powered on, head flew for 11 months... and all the read errors successfully corrected; no big deals. I decided to note anyway the read error rate, which had a value of 60M (normalized 119, threshold 6, worst 99). Today (3 days after), I checked again those numbers and the read error rate value is at 215M, which seems to me like a huge increase in a little time. The normalized and worst values haven't changed anyway, so the assesment is still OK in the SMART data. Should I be worried? My data is backed up, but should I be already buying a new HDD for my laptop? hard-drive smart share|improve this question asked Jan 21 '15 at 22:09 Peque 551312 It may be simply a loose connection. Try to disconnect the HDD and install it again. –gronostaj Jan 21 '15 at 22:15 @gronostaj: The HDD is mounted with screws, but anyway I will try that. Thanks! :-) –Peque Jan 21 '15 at 22:29 1 There has to be some type of data connection. 215 million errors is not normal. Be sure you understand how S.M.A.R.T should be read it snot always obvious. –Ramhound Jan 21 '15 at 23:37
