Ultimamente o meu pc tem-me brindado com alguns bluescreens!ja m fartei de pesquisar mas n csg perceber a origem do erro! Fiz um teste hoje no SpeedFan e eis a analise que o site me dá: [h=2]Hard disk health and reliability analysis[/h] 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 information, 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 almost as good as a professional expert advice about your hard disk status. Your hard disk is a ST3500320AS with firmware SD15. The average temperature for this hard disk model is 31°C (min=24°C max=40°C) and yours is 28°C. Attribute Current Raw Raw Read Error Rate 88 000000A32264 Spin Up Time 95 000000000000 Start/Stop Count 97 000000000C4B Reallocated Sector Count 100 0000000007FF Seek Error Rate 78 000410DE95E1 Power On Hours Count 85 000000003663 Spin Retry Count 100 000000000008 Power Cycle Count 97 000000000C43 End To End Error Count 100 000000000000 Reported Uncorrectable Errors 100 000000000000 Command Time Out 100 00040004001D High Fly Writes 100 000000000000 Hardware ECC Recovered 34 000000A32264 Current Pending Sector 100 000000000000 Offline Uncorrectable Sector Count 100 000000000000 Ultra DMA CRC Error Rate 200 000000000000 All the attributes of your hard disk are above the S.M.A.R.T. thresholds set by the manufacturer. This is good. SERIOUS ISSUE : your hard disk has 2047 reallocated sectors. Hard disks do have spare sectors (usually from 256 up to 2560) used to replace bad ones. This remapping operation is transparent to the end user. Anyway, this can lead to degraded performances (because remapped sectors are in different places of the disk than the original ones and the head needs additional moving). If reallocated sectors grow over time, you might encounter some serious troubles. A backup of the most important data is suggested anyway. NOTE : your hard disk Power On Hours Count attribute current value (85) is below the normal range (99 - 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. NOTE : your hard disk Power Cycle Count attribute current value (97) is below the normal range (100 - 100) reported for your specific hard disk model. Basically your hard disk was power cycled more times than the maximum number the average hard disk was. Power cycles put some stress on the hard disk mechanic. Sometimes power cycles can be caused by a loose hard disk power connector. Make sure it is properly fastened. The overall fitness for this drive is 0%. The overall performance for this drive is 79%. The link to get back and see a new report about this hard disk in the future is this. Consider that new hard disks and new checks are added over time.
