OK, I got a hold of an older Series 3 (OLED) on Craigslist. I mainly got it for parts to for my other lifetime Series 3 OLED. glo remote, stock 250GB hard drive and wireless USB adapter. Anyway, I recently also got a older DELL desktop PC that had a Samsung 500GB SATA drive in it. I pulled the Samsung drive from it, put a Series 3 image in it and stuck it in this Series 3 (OLED). All worked good until recently. I kept getting random reboots. I actually put the original WD 250GB stock drive back in it and it works fine. Therefore, I think something is going on with the Samsung drive. I want to run a full diagnostic scan on it, but where do I go to get software that will do this? I think I read that Samsung drives were bought by Seagate so not sure which site I should go to in order to get the needed software.
