My HDD has just started to make pronounced clicking noises.
Is this significant? Peter |

It s usually the sounds of the drive mechanism hitting the stops while it tries to read or write data. It is seeking a location of the disk and having problems locating it, thus the banging around much like someone looking for their glasses in a dark room. If it were me I'd be transferring all the data from that drive to another as soon as possible. While it is possible to "fix" the problem on some drives by reformatting them the problem usually just gets worse until the drive fails totally. Download the diagnostic software from the drive manufacturers web site and run that. If it reports the drive to be in good shape than possibly a reformatting and reloading of the drive my fix things but prepare for the worst just in case. |

Peter If the computer is running Windows, and the disk is connected to a regular disk port, you can use the SMART tab here, to get drive health information. The SMART numbers aren't always easy to understand or decode, but some of the entries in the table of data, can point to trouble. http://www.hdtune.com/files/hdtune_255.exe You can post a picture of your SMART data, for comments. http://img10.imageshack.us/img10/9393/hdtunesmart.gif The company that made the disk, will also have utilities for download, that can test the disk. Clicking means a regular access attempt failed, so the drive attempted to go to a known location (track 0 or maybe the track that holds the initial information used by the controller). The click then, or noises like that, hints that the drive is having trouble completing normal operations, and is resetting itself in an attempt to correct the situation. On some of the older drives I've worked with, the click is the sound of the head assembly hitting a "stop" at one end of its travel. You may have very little time, between hearing a click sound, and having it fail. So time is of the essence - make a backup as soon as possible. The backup takes priority over everything else, even testing programs like the one above. If you have a complete backup, then there is less to worry about. The backup should be stored on an entirely separate drive. Copying the data onto the current drive, isn't much good to you if the drive fails. If your computer only has one internal drive, connecting an external USB hard drive would be a good place for the backup. To give an example, I had a 40GB drive a few years back, that began to act up one night. I was tired and it was late, and instead of backing it up, I went to bed. When I turned on the computer the next day, the drive was dead, and all my data with it. I've never had the money to waste on data recovery companies, so when a drive fails, I'd better have a backup. HDTune also has an error scan option. It uses colored blocks in a graphical display, to show the health of the drive. But you'd only use the error scan, as a check to see whether the drive can even be backed up. If the backup fails, because the drive stops reading data, you can try the HDTune error scan, to spot what parts of the disk are damaged. For example, if you're not using the whole disk, and only have a partition near the front, then the HDTune display might be showing you that the most severe damaged is towards the end of the disk. When a number of sectors are bad, there is a technique for making the best of a bad situation. http://www.cgsecurity.org/wiki/Damaged_Hard_Disk ./ddrescue -n /dev/old_disk /dev/new_disk rescued.log ./ddrescue -r 1 /dev/old_disk /dev/new_disk rescued.log That is a two pass attempt, to copy one disk to another at the sector level. If you've ever attempted to transfer data the normal way, when a drive is really sick, it is so slow, it just never completes. Programs like the one in that example, allow the attempt to be sped up on the first pass, while the second pass "fills in the gaps". If a sector cannot be captured, it is filled with zeros instead. Using the flaky copy made, then you can attempt to do CHKDSK or use other repair or file scavenger utilities. This is an example of a scavenger. http://www.cgsecurity.org/wiki/PhotoRec Disks also fail, without any warning, and sometimes this is due to a bug in the disk controller board firmware. When you buy a disk drive, you should Google the part number, to see if the drive has known issues. In a couple of cases, it is possible to revive a drive with a firmware based problem, using a TTL level serial interface on the controller. Paul |

My HDD has just started to make pronounced clicking noises. Is this significant? http://en.wikipedia.org/wiki/Click_of_death There is a difference between clicking and buzzing. Buzzing means the heads are flying all over the place to read and write data which means there is a lot of data going to or coming off your hard disk. If it's buzzing then you can using something like SysInternals' Process Monitor to see what is causing the massive reads/writes. If the hard disk is clicking once (not repeatedly) and then spinning down, you could have a power scheme that powers down the hard disk at very short intervals. The hard disk isn't actually powered down. Power remains up to energize the controller board on the hard disk. Just the platters are spun down to conserve energy. A click followed by a turbine slowing noise means the platters are spinning down to stop. If you have multiple hard disks, the idle time for each is measured separately so they may spin down at different times. Click and spin down. Then when you or a process access the idle drive, click and it spins up again. In Windows XP, the shortest turn-off (idle) time for a hard disk is 3 minutes. You didn't mention how often or at what rate you hear the clicking noise. |

First thing to do is back up any important files just in case it 'conks out' altogether until then use it as little as possible. Davy |

I own two computers and originally *three* of the four intern harddisks clicked repeatedly when shutting off the computers! You heard click...sound of harddisk spinning up, and this some 5 times before the device's definite spin down. And I have used these drives for a long time since (2 of them have disappeared since: one has been replaced and one replaced by a ssd) Massimo |

: My HDD has just started to make pronounced clicking noises. Is this significant? Sounds kind of like a turn signal? You'd best get everything you can copied off of it as fast as you can. If you're lucky you can get the whole thing cloned. If that fails, slave it and copy off everything that it will allow you too. Put the drive in a baggie and put it in the freezer overnight. Lots of times that'll revive them long enough to get the data off. Been there, done that. -- -- I'm out of white ink -- |

Paul Thanks, I ran the chkdsk f on the HDD and that stopped the clicking noises. It's been quiet for several days now. I had a bad experience once before with a system HDD when the faulty power supply went berserk and fried the control card of the HDD. I had to run around the town to find a new HDD with a similar card and then swap it over. This fixed it, but with a lot of trouble. |

I think you have it since, well, ten years or so? usually my HDDs can reach this age before failing. Anyway, you have to backup all you can and buy a new HDD, that's all. -- Check all the new Tech at http://Shop-for-Computer.com and http://ConsumerElectronic.biz |
