i just got reminded of importance of using the PSU for all devices (less printers, etc) connected to my machine, which in turn is a laptop and has charged battery to act as supply failover, but the hdd connected to it, doesnt have a separate fail over power supply
luckily i went to transfer some linux images from one drive to another (irony is, to a folder named check since originated from a fragmented ntfs drive
), so no big harm- only one file is affected
and can be redownloaded...
situation in specific: the power company opted to do a milisecond blackout, it was barely visible, but the modem reset, phone connected to it reset, tv went off, etc, comp hasnt due to its battery on and charged, BUT the transfer was off, reported error and disks unmounted
so, just as a reminder to everyone, feel NOT safe when using the laptop with external storage connected needing a separate power supply (not the usb stuff)
ps: any advice on home made brew regarding this? i wouldnt like buying a proper psu just for this, cause it happens really very rarely.
