| 745875 | 2009-02-09 18:40:00 | Sorry about this guys, back again, but this is a steep learning curve for me. Anyway, Everest Reports on the SMART Reallocated Sector Count: Threshold: 36 Value: 100 Worse: 100 Data: 0 Status: OK: Value is Normal. There’s a page full of other reports but at the end of the day they are all OK: Value is normal as well. So where does this leave us? :confused: Anyone care to explain the data above? :confused: |

| 745876 | 2009-02-09 19:38:00 | Mine says exactly the same in EVEREST. I should try and grab a HDD Ive got a feeling is failing out of my linux fileserver and chuck it in a machine with EVEREST :) |

| 745877 | 2009-02-09 19:59:00 | Good thinking Chill, I just checked my own computer and got the following: New 80gig C Drive: Everest Reports on the SMART Reallocated Sector Count: Threshold: 36 Value: 96 Worse: 96 Data: 171 Status: OK: Value is Normal. Old 40gig E Drive Everest Reports on the SMART Reallocated Sector Count: Threshold: 9 Value: 253 Worse: 253 Data: 0 Status: OK: Value is Normal.. I guess the question now is what do all these figures tell us? :confused: . (Just thinking, probably my drives are stuffed and the laptops fine) :lol: Fascinating stuff. :) |

| 745878 | 2009-02-09 21:49:00 | Thanks for that Agent, I'll follow that up. However, it raises a couple of other questions. 1: Wouldn't Seatools have done this when it passed the "SMART" test? :confused: 2: What is an acceptable number of reallocations given that the Manufactures expect this to happen? :confused: Seatools does not check the SMART data in depth. It only checks to see if the drive has 'tripped' SMART to flag itself as failing. This is when any value has gone outside predetermined limits in the drive. These would be different between drive families, maybe even models. An acceptable amount depends on the preset limits, whatever the manufacturer feels like. Usually it's a small number. The general consensus is that any reallocated sectors are bad as more will usually follow pretty quickly. If the limit was 100 sectors, and you had 99 sectors reallocated, SMART would still tell you that your drive was OK. For your SMART readouts, try SpeedFan. There's an option to analyze your HDD status online which tries to provide a diagnosis and explanation. I suggest you try that, it's a lot easier than trying to understand the results yourself. |

Thanks Agent, only problem there is this Laptop is a wee way from being Internet capable. :) I just don't believe there isn't a programme that will retest a bad sector and adjust the bad sector table accordingly if it now passes. :confused: |

| 745880 | 2009-02-10 23:06:00 | I think Spinrite and similar programs may do that. There may be free ones but I don't know. Unfortunately Spinrite is a very ... demanding application, if a drive is failing, that much work required to run Spinrite can finish it off. Then again, you could argue that's a good thing, if a drive can't handle extensive tests then it's no good. Use of program such as sprinrite assumes that your heads are working 100%, as it performs full read and (re)write testing on all sectors. If your heads can't write properly, it'll ruin all your data. Best thing is to use something like DD Rescue (the new version) to recover stuff (if the drive is really bad, or just backup normally if it's OK), then go about playing with things like Spinrite |

| 745882 | 2009-02-11 20:24:00 | Well in the absence of any programme to retest and reset the Bad Sector table I thought I would try the "changing partition size trick" . So, I defragged the drive and then using Partition Magic pulled the partition in from 40gig to 30gig . My intention was to drag it out 40gig later . However, the exercise completely stuffed things and the machine wouldn’t even boot . Various recovery programmes failed to remedy the situation so having lost interest I shifted the partition back to max, reformatted, and reinstalled windows . No problems, there was nothing of value on the computer . Anyway, Chkdsk now assures me there are no Bad Sectors, so it is singing from the same songbook as Seatools and the other diagnostic tools . This leaves us with only the query of the information stored by SMART on the HDD itself . SMART Reallocated Sector Count: Threshold: 36 Value: 100 Worse: 100 Data: 0 Status: OK: Value is Normal . It’s a Seagate drive so where would I find an explanation of these figures . Someone must be able to interpret them or it would be a waste of time providing them . :confused: I guess all that remains is to see how long it is before Bad Sectors start to be reported again . If indeed they do . There may yet be some merit in the article whereby the author suggested there were an awful lot of HDD’s in the Landfill which were quite ok . ;) And full marks to HDD Regenerator for getting us this far . :thumbs: |
