Hi Bro,
for 2) If are you using a thumb drive, mind to check it first.  There is a common case of imitation one from China. "Fake Flash" refers to low capacity flash drives (and memory cards) that have been "hacked" so that they appear to have much more capacity than is physically present on the drive.

These drives operate normally under low usage, but will corrupt data once their "true" capacity is exceeded – potentially leading to massive data loss.
