Yes, that's very much what one would expect of any successful retailer. My experience with Canada Computers since 2000 -- 25 yr -- has been good : they do try not to sell anything which cb unreliable. However, as you say, all it takes is 1 broken link in a long chain. I tried formatting one of the sticks using Gparted + Glances. After 10 hr while I was asleep, it had formatted 1 partition & was clearly stalled on the 2nd : the Parted progress bar was moving to-fro, Glances reported critically high CPU I/O wait of c 25 % & that it was writing small amounts of data to the partition every 30 sec . I had to cancel Gparted from the root command line & then tested the 1st partition, which allowed me to edit a file, but was very slow at everything. So yes, at least 1 of the sticks is unusable & probably both. I can take/mail them back to the store & ask them to test them with Linux & refund my CAD if they confirm they're defective. I would expect this store to be honorable re it & to be pleased to have someone report the problem st they can report back to their supplier & avoid future trouble. Frank had a useful suggestion re alternative devices, which I will reply to separately. Your own comments thereon wb useful. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatcadotinterdotnet
