anyone no how close a harddrive can be to a cathode tube tv without corupting the drive? the TV is a sony trinitron (KV-28WS2U). Harddrive is a seagate sata 120Gig. In the middle of backing up now incase the worst happens. If some one can save me the trouble of finding out the hard way that would be great :)
 
mine have been about 1/2 a metre away for the past year, but i want to put the TV on top of the case, which would put them pritty much in contact. I no I would have no trouble with a monitor, its just the size (and therefore the output) of the TV that is worrieing me. What CRT you using m8?

Edit: that better :)

Never had any problems with the hard drive in my Sky+ box, and its sitting just underneath my 28inch Sony Trinitron widescreen CRT without any problem at all.

I wouldnt really worry too much about the hard disk in your computer to be honest.
 
It's CRT! Cathode ray tube! Not CTR that stands for Click-through rate on google adsense.
 
What about Microwaves???
Her indoors has decided to rearrange the kitchen and that has put the microwave on the other side of the wall (breeze block) directly behind the PC in the AV room.
It affects the monitor, making it go all wobbly when the micro is on, and if you see my other latest thread the PC has just failed. :eek:
Although to be fair she rearranged the Kitchen a good few months ago. and wont budge on it's position. :mad:

Hard drives are insanely good at retaining their data, even under quite powerfull magnetic fields.

Infact it takes 4000 gauss to reliably erase a hard disk. The 'background' magnetic field from the earth range from 0.3 gauss to 0.6.

For another example, the TV show mythbusters found it took over 1000 guass from an electromagnet to corrupt the exposed magnetic strip on a creditcard.

Basically dont worry about your hard drive, unless its phyisically faulty it will hold onto its data very well indeed. (I found a 10 year old hard drive in my loft a while back, and it still had a fully working bootable copy of windows 95 on it.)

PS, A TV tube can be affected by as little as a 1 gauss magnetic field. CRT's are very sensitive to external magnetic forces. Just wave a magnetic tip screwdriver near the screen and watch it pull and distort the colours.
