[H] External drives (USB) and power requirements

2013-07-02 Thread Thane Sherrington
I notice a lot of external drives (2.5) come with a single headed USB cable, yet the drive requires 750 to 1000 mA. How can a single USB plug provide enough power to keep the drive viable over the long term? (I also notice I see a lot of dead drives like this - the dual headed-USB ones seem

Hello Thane, Those external HD's are not for the purpose of running 24/7. Also, note some laptops on battery power can not power up those HD's either. Regards, On July 2, 2013 at 7:34 AM Thane Sherrington th...@computerconnectionltd.com wrote: I notice a lot of external drives (2.5) come

Hello Thane, Even those with the 2 USB connector type cables should not be used 24/7. In fact all External HD's should not be run 24/7 due to inadequate Power source, of course those SCSI/iSCSI/Fiber externals are exempt. Why, you ask? Well the power source on even the 3.5 USB drives in not

Thermal Interface Material :) It could mean thermal paste, or like these guys were talking, a metal plate on top of the processor die. Julian Julian On Tue, Jul 2, 2013 at 3:20 PM, DSinc dsinc...@epbfi.com wrote: Really enjoying this discussion. Can someone remind me what 'TIM' is

Hello Thane, Yes, do the business and shut them off. With the new SATA HD's out now it does not require much power to run them. Just don't run them 24/7 On July 2, 2013 at 12:10 PM Thane Sherrington th...@computerconnectionltd.com wrote: At 01:59 PM 02/07/2013, Tim Lider wrote: Hello Thane,

I had an external WD Book that went bad ... but I wasn't running it 24/7... just occasionally, but sometimes I would forget to power it off and leave it running for days. When it did die I figured it was the heat rather then then anything to do with power adaptor. Thermal test showed me that

You have a point there. In most cases, the jobs that go through our shop here, the HD fail due to power problems. These power problems are either power spikes, power drops, or shorts. Keep in mind HD's can not be repaired by replacing the PCB anymore, there is so much more involved. Regards, On
