Yes! - temperature and drive environment is VERY important - using those=20

drives are at very similar temperature to each other.  Keep any=20
unnecessary heat sources away eg, warm to hot exhaust air from computer=20
power supply or motherboard etc, away from the drives, also do the clone=20

allot of the times we find that drives that come to us, have already=20
been damaged beyond a useful point.  History seems to say (based on=20
experiences) that diy data-recovery can sometimes kill the drive in=20
trying to fix it themselves.  So **IF** the data is extremely important,=20
you may only have one chance bite at the apple - after that it's point=20
less.  NEVER WRITE to the troubled drives - NEVER power the drives=20
unnecessarily, to reduce other possible problems.  Lastly specialised=20
raid / drive snap imaging, can greatly help, because then you can=20
operate on the image more than once and not the real hardware, that way=20
you can try different methods to repair or recover the drive and/or the=20
data.  We have had many successes, but also some failures.  Best of luck!
