This is so not fun to report but recently I had a dear client of ours bring their external hard drive in reporting external hard drive files lost.
They had been considering our services but turned us down, not sure why, could be the expense perhaps. I understood though.
About 2 months later they called me to say their external stopped working. Upon inspection it was discovered the external case had corrupted the partition table and the drive was not working at all anymore. We sent the drive out to a specialty shop for inspection and to retreive all their data was going to cost them $700.00 !
I was quite sad to hear that.
