Question about Seagate Barracuda 7200.7 ST380011A 80 GB Hard Drive
I have a spare 80GB IDE Barracude drive connected to my computer as a slave. I only use it for keeping backups. Since keeping it connected at all times uses power as well is becoming prone to virus attacks, I was wondering if it is safe to unplug the power cable while still keeping the data cable connected. I don't really want to unplug the data cable everytime, its easier to just pull the power cable out.
I just want to know whether its safe (for the hard disk) to keep the system running with its data cable connected and the power cable unplugged.
Thank you for any help.
Bad advice, !! he has PATA drive.!
only the Esata external is hot swappable. as is the old SCSI HDD.
if it has a molex connector , HDD, power, do not hot swap this connector, as you damage the logic, the logic does not allow instant power ups, (hot wiring) it does not.
when you do that the rise time is near the speed of light and the
chips can latch up , then burn.
PATA. when you power down and pull the power connector, dead.
then leave the data cable (parallel cable ribbon) connected
this loads the buss,in an illegal way, this causes other devices on the buss to fail, Data corruptions, like the DVD, CDRom, or the other
hard drive, (i run 2 drives , since 1981 with first ever pc.) IBM.
i have an Esata external drive 2Tb, AND IS hot swappable. RTM.
first read the data sheet on you HDD, see that page?
at seagate? hot swapping power that old drive is not good.
hot swapping data, will no cause damage like above, but will corrupt data, i see tech in the shop wondering why the windows install disc
hangs, i point the the HDD , there, with no power.....
100 of times, ive shown them....
DVD on same cable is dead power drive.
same with 2 HDD on same cable,
some hard drives float the i/o buss and others do not , with power
removed, the data sheet covers this..
A smart tech assumes no float , unless you like , chasing tail all day.

It is perfectly safe to remove the power cable from a hard drive but leave the data cable connected. Make sure that whenever you want to connect or disconnect the power cable, your computer has been shut down first. You could do it with the computer powered on as well, but this would not be good practice and you may put errors on your drive.
