Both usb sticks had been used for backups, one is a once used backup of my keyring flash drive, the other has been used for wallet backups, the backup flash drive is about a year old, the keyring backup one i bought and used once 3years ago, the keyring flash drives contain 6gbish of data,
and work Perfectly Fine on other computers, and used to work perfectly fine on my main computers!, seriously i can grab any fully functional (sadly all the drives in our house are 8-16gb) usb hdd and it doesnt work in my main comps. Its not the usb sticks.
I havent touched my drivers, I havent changed hardware, i dont have antivirus on majority of the computers (not mine/dont use them) when i disable it there's no differance, tried usb3.0&2.0, no change, tried front panel usb ports and back ones, no changes in behavior...
Had a chat with our senior engineers here.
Recommendations:
Update your chipset drivers ( motherboard drivers )
Complete a speed test on the flash sticks, see what they bug out on - sequential read/writes or both.
USB 3.0 will not cause any issues, its an open standard - 2.0 is 120% supported.
How old are the sticks? Do take into consideration flash drives only have a limited data usage life, e.g how many cycles are used.
Also what file system are you running on the drives? Some drives dont like fat, some dont like ntfs.
Thats a good idea to test when i get home, i just ran test at my buddies house (not home) and it works perfrctly fine, no errors, speeds fine... used HDTune..
Ive tried all manners of formats on the drives to no avail, makes no differance other than speed
Of course ive taken into account the limited read/writes, thats why i made backups
