Some useful reading if you aren't sure about backup... http://www.extremetech.com/article2/0,2845,10684,00.asp (old but still has some valid pointers) http://ezinearticles.com/?Essentials-of-an-Effective-Backup-Strategy&id=100980 http://en.wikipedia.org/wiki/Backup (I know, I know, it's wikipedia but it at least lists a lot of the common terms you will find when investigating backup)
I had 2 1tb drives both went within 1 day of each other. work with a lot of computers and we find one of the main problems is replacing drives yeah they do go and some times you can be lucky or you can get say a bad batch and have like 5 of them go
they do fail but in the pcs i own at home ive never seen a drive totaly fail ive had them start grinding and the performance degrades badly but the drive is still accessible. Never had a total failure were i cant recover the data at work we replace hard drives often.
Worst I have seen was a Quantum Fireball 20 GB drive with degraded bearings which would have made a banshee wallow in pain. It still worked just fine, though, even if the use of hearing protection around it was advisable A HDD my brother owned got fried many years ago due to a cheap (L&C) PSU with the usual far out of spec ripple and voltage sags/spikes. Wasn't the fault of the HDD, of course. His videocard (Radeon 9600) went down with it
I've had one sort of fail, it was purchased in 2002 120GB maxtor, it had alot of bad sectors by 2008.
Where I work it's: Hard Drive PSU RAM Graphics card (Normally incorrectly seated, rarely dead) Motherboard Processor (never seen it)
yes, they fail. i work in small business IT and i see on average one hard drive die every week. still, raid5 is probably sufficient. your 6TB should be 5TB, not 4TB.
Nope... if he has 3x 2TB disks, then one of them will be for parity in RAID5, hence only 2 disks for storage, 2x2 = 4TB You work in IT? Only kidding... easy to get confuddled.
Processor got me thinking built my first pc back in 2000 and it got me thinking started work in 2008 and in all my time i have not seen one go is this just luck ?
Hmm, I've never had a HDD fail, I had a graphics card and process fry on me. Infact it was when I was just getting into computing. We bought a prebuilt machine, which had shoddy cooling. Shortly after we got it the processor died, they wouldn't do anything under warranty, so we did it ourselves. I've got a 40GB maxtor that came with that machine, that looked like it was going to fail, but it's been running for the last few years fine...
"Because my 4Tb could be 6Tb if I removed the RAID mirrors" Now, raid mirrors suggests he has at least 2 drives in RAID 1, implying that they're 1GB disks. Ah well, it's easy to get confuddled.
I'd say it's likely that as they're so intricate, they have to be built to a very high standard. Short of overvolting/overheating, I don't think much can go wrong. The only time we've replaced a 'broken' processor was where a customer had taken it out and in the process snapped some pins (AMD), which isn't the processor's failure, it's the user's.
It was a 2.4GHz P4 or something, on one of my dad's spare company PCs. The machine gave a bunch of temperature warnings and one day it just didn't start up, and we took out all the peripherals and deduced that it was the CPU. Swapped in a 3GHz and it worked just fine.
I've only see one processor in rought 200+ machines. Was a old AMD athlon. I had my pump fail in my first watercooling system (the only good TT Bigwater SE produced by the looks of it ) and it was cooling a Pentium D 920, the think was running for a good hour before shutting down. My lil brother even had Rome Total War going for 30 minutes a time and all it'd do was shut down. I think modern CPU's are nearly industricable...
had a drive fail on me for work and it was painful as a lot of stuff was not backed up...will never fail to back up again
I had a drive fail a few weeks after buying it. All in all I've had 4 or 5 drives go over the years, one of which was due to a cheap PSU blowing up.
Forgot to plug my cpu fan back in after needing to unplug it. After like 30 mins of bf2 there was lots of loud beeps then a black screen, it reset itself, then a bios screen showing 'over clocking failed, press to run setup'. I got a titan fenrir and I could feel heat radiating off of it from a few inches away. By the time I had turned it all off, plugged the fan back in and switched it back on again, and gone into the bios and looked at the cpu temp it was still over 90 degrees C. God knows what it was at at shutdown. 8 months ago and still going strong.....
Never had a HDD just stop and fail. They are one of the better components in a PC. Had a few old ones start to give read problems, get slower and then louder. You then know its time to change them. But I always turn off my PC and always have done. If you leave yours on for days or weeks at a time problems with hardware will occur sooner rather than later. Why do people leave theirs on for such long periods? Even on idle Windows will use resources and save temporary file/memory dumps. There is no such thing as idle in an operating system!
