I've got this WD 500 gb Firewire external My Book drive I've been using to store mostly video files for a big video project. It doesn't have an on/off switch, it powers up when power is first applied, goes dormant after a period of inactivity and restarts when you try to access it. It's worked flawlessly until today. Normally the blue light in front dances up and down during boot up as well as whenever there's data transfer but now I notice the light flashes briefly when power is first applied, the drive makes some noise like it's starting to spool up but then shuts down. The couple of h/d's I've had die in the past gave me some warning, made weird clicking noises for a while before crapping out. This one was working perfectly normally until now. I wouldn't think overheating would be an issue with this drive, the case is extensively vented unlike most external drives I've seen. It doesn't get used that much. Anyone have experience with these drives? Any chance there's a power supply inside the case that's causing the problem and can be swapped with another from an identical drive? Would be a huge Aaaaargggghhhhh!!!!!! to lose the hundreds of gigs of files. Any chance WD would do such a repair? I don't want another drive, I need THIS drive to work. Thanks for all assistance.

Unless a drive has a decent volume of air moved across the PCB, it's doomed to a short life. USB caddies are death for any drive. Unless the PCB has a fan on it, even a tower spells death - unless maybe the drive sits on the floor of the tower rather than the confines of a 3.5" bay ... and even then it'll struggle. Best thing anyone can do for a caddied HDD, is give it it's freedom by cutting the PCB side off the caddy box and attaching an 80mm fan (and grille) - that or remove it from the caddy completely. It doesn't get used that much. >> >> Anyone have experience with these drives?

Is it this one? http://www.wdc.com/en/products/products.asp?driveid=351 3 possibilities 1 The AC adaptor has died, check with a voltmeter or subsitute adaptor. 2 The Firewire electronics have died in the MyBook or your PC. Try the unit on another PC and if possible another firewire unit on your PC. (check the cable too) 3 The drive itself has died. Check this by opening the case and mounting the drive inside your PC as a slave drive. You may have to add a PCI adaptor if it's SATA and you don't have SATA inside your PC. If this last one doesn't work then it's off to the data recovery specialists. If the drive does show up as a slave drive then you can make the backups you should have made in the first place!!!!!!!!!!! Best Paul.

It's worked flawlessly until today. If as implied, you are powering it from the firewire connection then you are very lucky it ever powered up. Clarify: The WD 500gb firewire drive would have been supplied with it's own dedicated AC power unit, do you use that or is it drawing(draining) it's power supply via firewire? > > Normally the blue light in front dances up and down during boot up as > well as whenever there's data transfer but now I notice the light > flashes briefly when power is first applied, the drive makes some > noise like it's starting to spool up but then shuts down.

Plenty of recent threads on externally connected HDD's, did you read any of them? The simple steps first: Have you checked Device Manager to see if the drive is flagged as problematic - exclaimation or questionmarks? There is nothing in your post to indicate operating system, but your google groups post indicates XP in headers, so... Do you have the "Safely Remove Hardware" icon on display in the notification area or taskbar? If not: RIGHT click in the area A dialog appears "Customize Notifications" Scroll and locate "Safely Remove Hardware" Use the drop down to select "Always Show" Click the OK buttons and close that dialog The icon is now available and use it to remove the Firewire drive. Then goto Device Manager and UNInstall the firewire drive. Do NOT uninstall any associated software that came bundled with the drive - leave all that installed. Shut down your computer. Disconnect the firewire drive. Find, purchase, steal a dedicated power supply for your firewire drive. Restart your PC without the firewire drive DISconnected Download and install WD diagnostic tool (firwire version): http://www.softpedia.com/get/System/Hard-Disk-Utils/Western-Digital-Data-Lifeguard-Diagnostics.shtml Fully shut down your computer Reconnect the WD 500gb firewire HDD with it powered from a dedicated power supply. Restart your PC. Windows "Found new hardware" wizard will detect the connected firewire HDD and will correctly reinstall it. Check in "MyComputer" that it has beed assigned a drive letter. Check in Device Manager that it is not flagged with an Exclaimation or Questionmark. Now run WD's diagnostic tool which will check it's health and try to repair any problems found.

Not my experience. I used to run my drives fanless. Had about 5 failures over 2 years. Since then (about five years ago) I've been running another 5 or so with fans .... and not a SINGLE failure. All were and continue to be on high quality PSU's and mobo's. Coincidence ? Doubtful.

I don't think so. Yes it is good practice to have good ventilation for a PC in general. But freezing the balls of a Hard drives logic board is no guarantee it is not going to die. In fact if you 'read' the Google document and observe Figure 4, you should note that cooling the drive to much is likely to 'increase' the failure rate. Paul.

Freezing ? Even with a fan, they're still quite warm. But ultimately, you appear to be unaware of the class action suite bought by the US gov.t against IBM for HDD failures. And totally oblivious to the vested commercial interests at play here. This study was not conducted by any kind of academic institution - or subject to any kind of peer review. We have no knowledge of who funded it - or any way of qualifying its veracity. Anyone can claim to have conducted a massive study - and go on to draw whatever conclusions they choose. I would rather believe the evidence of my own experience than some bullshit 'study' (read : commercial propaganda). Other than which, any overclocker will tell you that nothing kills a chip faster than heat. Try removing the heatsink from your GPU. It's common sense, if nothing else. > In fact if you 'read' the Google document and observe Figure 4, you > should note that cooling the drive to much is likely to 'increase' > the failure rate. > > Paul.

Without reading the rest, or the replies, I will just say one thing. HD's fail, especially external ones (3x the price for the $10 Chinese box and a $2 Chinese power adapter with the same drive inside that you could have put inside you machine). DVD's (or expensive tape drives used by corporations) are the only way to backup safely.

On that basis however 'my' experience tells me having a fan blowing on a Hard drive does not extend it's life. In fact just the opposite. (Unfortunately my sample has only two failed drives out of 14 installed.

On this machine it was a drive in the fan air stream that died, again at about 24 months. Cases 3 to 7 didn't have any drive failures and none of those had a fan blowing over the hard drives. Paul.

That heat causes HDD failures does not somehow exclude other factors from doing so too - as you are inferring. The Google study presumably polled a lot of PC users about HDD failures. Unfortunately, there is a component of the population that refuses to accept things they cannot understand - a typically left-brain-dominant characteristic that derives from an ability to see the bigger picture. Techies are predominantly left-brain thinkers and as such, frequently express frustration when unable to understand WHY something happens. This is frequently manifest as an autistic-like, stubborn refusal to accept what they see before them - indeed, it can even be manifest as a need to prove the opposite of what they see before them, so irksome do they find their failure to understand. But then, left-brainers are not big on understanding because they lack the vision and imagination required to see the wood for the trees. Of the laptops I have to repair, I'd say 80-90% are down to failed HDD's. My desktop repairs have nothing like this failure rate. Draw your own conclusions. > Case #2 has 3 drives in it, two had a front mounted fan blowin air > over them (again from new), the third was buried in a 3.5" cage under > the floppy drive. > On this machine it was a drive in the fan air stream that died, again > at about 24 months. > Cases 3 to 7 didn't have any drive failures and none of those had a > fan blowing over the hard drives. > > Paul.

The power supply is external, but there are voltage regulators inside the drive enclosure to convert the +12V from the power supply to +3.3V and +5V used by the chips in the drive and the interface circuitry. > Aaaaargggghhhhh!!!!!! to lose the hundreds of gigs of files.

Data recovery is NOT included with the warranty, but you're supposed to have an extra HD for backup anyway because computers can wipe out tons of data in a hurry. Also a 1TB drive costs just $100, which is a lot, lot less than the cheapest data recovery service.

MOST interesting comment from someone with a 13-year old's nickname (if it's your /real name/, my deepest sympathies) who (to my recollection) has never posted ANY advice, and who uses OE for newsgroups. I am often wrong, and have no problem with admitting it when I am corrected by someone who knows what they're talking about. But NO ONE is ALWAYS wrong or ALWAYS right - including you. Now go fuck yourself.

What struck me about their study, is the word "humidity"
doesn't appear anywhere in the report. And humidity is a
factor in disk reliability.

I judge studies by their attention to detail.
Without knowing what combination of temperature and humidity
is present in each facility, there is no way to judge whether
the missing factor is important or not.
If you download an OEM spec for a disk drive, there is
a temperature/humidity graph in it. It documents the allowed
values of temperature and humidity for a disk drive. Which
means in any study, humidity should be documented (because the
disk manufacturer acknowledges it is a factor). Or at least the
word should appear in the study at least once, as in
"we chose to ignore humidity".

Yes, but that's for un-a/c'd conditions (under which, the majority will be used). In a/c'd conditions, it become irrelevant because the temp is kept low enough that humidity is of no consequence to the cooling capacity of air. It documents the allowed > values of temperature and humidity for a disk drive.

Okay, extricated from the case and hooked it up with SATA cables, it's working fine. Apparently the My Book interface/switch died. Thanks for all input.

Apparently the My Book > interface/switch died. I sort of hate to say this, but didn't that sort of imply my rather simple rule has again proved to be correct? Now try to sell the external HD case for the $10 it /may/ be worth and you'll be done. ;-)

Nope, because the alternatives die too, stupid.

Rod Speed is the last great polymath. The most that you and I and the rest of us mere mortals can hope for is to learn a little about a lot, or a lot about a little. You are probably encountering him for the first time as an undesirable consequence of the OP's crossposting. When you crosspost to comp.sys.ibm.pc.hardware.storage you run the risk of introducing Rod Speed to an unsuspecting audience. It's a bit like bringing your neighbour's dog poop to your friend's house on the sole of your shoe. Most of the regulars have kill-filed the troll, but he still tries to get through by nym shifting. Pathetic, really. - Franc Zabkar -- Please remove one 'i' from my address when replying by email.

During the 1980s I was involved with one minicomputer installation that had problems with a particular Control Data BK7 series disc drive. After experiencing lots of static related issues (status errors), the customer installed a humidifier to increase the humidity to an acceptable level. In other climates, such as Singapore, the high humidity promotes mould growth on magnetic media, although I doubt that mould would get a foothold on disc platters rotating at 7200 RPM. :-) I found this interesting Samsung patent whose inventors claim that "flying height drops significantly in humid conditions" and that this can be remedied "by increasing the temperature of the air flowing between a slider's air bearing surface and the rotating disk surface it accesses".

Pathetic, > really. Well, if the FAQ is correct, at least the poor thing has something to amuse himself with. There is so much trolling spamming and crap on the Usenet it makes little difference in the final analysis, I think.
