It is recommended to examine the log of the disk regularly. I would also try Hddscan to look for warnings in the Smart Data results. Franna Expert Member. Joined Apr 18, Messages 2, Copy the contents of the HDD to another drive if there are any critical documents on it. Just in case! Joined Mar 13, Messages 6, Thread starter lincsman Start date Mar 25, I need to know if it is healthy or not, thanks.
I've recently had my HDD replaced by a brand new one, and all my data from the old one cloned, because the Lenovo toolbox scan failed on the short smart selftest. The guys from the local computer store told me that this would solve my problem. However, all scans that I run now still come up with the same results as before the new disk was installed. I've browsed the web, but haven't found a solution so far. Thanks a lot in advance for any advice, Vince from Holland.
This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question 1. What exactly is the issue that you are facing? The inability to read some sectors is not always an indication that a drive is about to fail. One way that unreadable sectors may be created, even when the drive is functioning within specification, is through a sudden power failure while the drive is writing. Also, even if the physical disk is damaged at one location, such that a certain sector is unreadable, the disk may be able to use spare space to replace the bad area, so that the sector can be overwritten.
More detail on the health of the drive may be obtained by examining the S. Attributes were included in some drafts of the ATA standard, but were removed before the standard became final.
The meaning and interpretation of the attributes varies between manufacturers, and are sometimes considered a trade secret for one manufacturer or another. Attributes are further discussed below. Drives with S. The error log records information about the most recent errors that the drive has reported back to the host computer. A drive that implements S.
The self-test routines may be used to detect any unreadable sectors on the disk, so that they may be restored from back-up sources for example, from other disks in a RAID. This helps to reduce the risk of incurring permanent loss of data. Many motherboards display a warning message when a disk drive is approaching failure. Although an industry standard exists among most major hard drive manufacturers,  issues remain due to attributes intentionally left undocumented to the public in order to differentiate models between manufacturers.
Because of this the specifications of S. Depending on the type of interface being used, some S. Even with a hard drive and interface that implements the specification, the computer's operating system may not see the S. On the Windows platform, many programs designed to monitor and report S.
For a list of various programs that allow reading of S. Data, see Comparison of S. Each drive manufacturer defines a set of attributes,   and sets threshold values beyond which attributes should not pass under normal operation.
Each attribute has a raw value that can be a decimal or a hexadecimal value, whose meaning is entirely up to the drive manufacturer but often corresponds to counts or a physical unit, such as degrees Celsius or seconds , a normalized value , which ranges from 1 to with 1 representing the worst case and representing the best and a worst value , which represents the lowest recorded normalized value. The initial default value of attributes is but can vary between manufacturer.
Manufacturers that have implemented at least one S. The following chart lists some S. Supported Hardware Mainboard fan control Measurement of temperatures. Monitoring and control of system fan speeds. Hard drive monitoring Hard drive health status. SMART temperature. Note that Seagate drives often report a raw value that is very high even on new drives, and does not thereby indicate a failure.

To break down the general question in order to answer it, I would be looking for comments on things like:. I suppose that the fact that a manufacturer produces both drives with and without free fall sensors says something about possible disadvantages. Or it could be standard marketing techniques where by making drives with and without results in larger sales volume than just those with the feature alone.
Not generally, no. The sensor is specifically calibrated to detect free fall like the laptop being dropped , not just minor bumps.
Traditionally, the HDD protection algorithm has been based on free-fall modeling, as explained below, in which the outputs of the sensors contained in the accelerometers can be easily captured by a digital oscilloscope or other data sampling system. The axes of the accelerometers are aligned with the X, Y, and Z axes, as depicted in Figure 4, thereby providing values of acceleration along the X, Y, and Z coordinates.
The Y 1 output is redundant and is not used. The outputs of the coordinate axes are sampled by a bit ADC contained in an ADuC precision analog microcontroller, which integrates the sampled data and feeds it to an internal compatible core processor.
The sampled data is then transferred to the computer—via an RS interface—for analysis. Figure 5 shows the sequence of responses sensed by the two sensors.
Values X and Y are supplied by one accelerometer, the values Z and Y1 are supplied by the other accelerometer. The Y-axis scale represents the values delivered by the bit ADC in the ADuC smart-transducer front end, plotted for all four axes. The test sled, placed at the edge of the table and caused to roll over, imparting angular acceleration—as depicted in Figure 4—produces the rollover data shown in Figure 5.Its primary function is to detect and report various indicators of drive reliability with the intent of anticipating g shock free fall event count hardware failures. When S. Hard disk and other storage drives are subject to failures see hard disk drive failure which can be classified within two basic classes:. These may include increased heat output, increased noise level, problems with reading and writing of data, or an increase in the number of damaged disk sectors. PCTechGuide's page on S. In its original incarnation S. A subsequent version of the standard improved failure prediction by adding an automatic off-line read scan to monitor additional operations. If there is an immediate need to update the offline attributes, the HDD slows down and the offline attributes get updated. The latest "S. Also, while earlier versions g shock free fall event count the technology only monitored hard drive activity for data g shock free fall event count was retrieved by the operating system, this latest S. A field study at Google  covering overconsumer-grade drives from December to August found correlations between certain S. It was measuring several key device health parameters and evaluating them within the drive firmware. Communications between the physical unit and the monitoring software were limited to a binary result: namely, either "device is OK" or "drive is likely to fail soon". Later, another variant, which was named IntelliSafe, was created by computer from paris with love full movie free Compaq and disk drive manufacturers SeagateQuantumand Conner. Each disk drive g shock free fall event count was free to decide which parameters were to be included for monitoring, g shock free fall event count what their thresholds should be. The unification was at the protocol level with the host. The Committee chose IntelliSafe's approach, as it provided more flexibility. Compaq placed IntelliSafe into the public domain on 12 May That SFF standard described a communication protocol g shock free fall event count an ATA host to use and control monitoring and analysis in a hard disk from dusk till dawn tv series watch online free, but did not specify any particular metrics or analysis methods. i scanned using HDDscan and found error in free fall event count. what do i need to do? G-shock/Free-fall Event Count It's the "G-Shock/Free-fall Event Count" that they're referring to. For that to have been triggered 76 times is very unusual, and virtually unheard. The spindle turns on, and hence the count is increased, both when the hard , BF, G-sense error rate Distance the disk has shifted relative to the spindle (usually due to shock or temperature). Number of "Free Fall Events" detected. Cancel Heads Flying Hours G-shock/Free-fall Event Count HDDScan smart test - "Current Pending Errors Count" has a yellow , G-shock/Free-fall Event Count, , , , I would also try Hddscan to look for warnings in the Smart Data results. You may now see a warning under the G-Shock/Free-fall Event Count. Errors Count UltraDMA CRC Errors G-shock/Free-fall Event Count. The sensor is specifically calibrated to detect free fall (like the laptop being dropped), and then a sudden and relatively massive increase in shock (g-forces). log it in the SMART table: G-sense Error Rate: The count of errors resulting from.
