bpwahlgren Posted July 17, 2009 Share Posted July 17, 2009 Our company has a script that backs up data on our customers servers running Linux to a Corsair 8GB flash drive. The drives are formatted Linux ext2. The script uses rsync to copy the files to the flash drive. Then does a sha1sum on the files to make sure that the rsync was successful. We've had instances where this has failed and the fix was to run badblocks in linux. My question is is it possible for a flash drive to get "bad blocks" and does it damage or shorten the life of the flash drive if badblocks is run on the drive?

Corsair Employee RAM GUY Posted July 17, 2009 Corsair Employee Share Posted July 17, 2009 Yes any media can have a bad block from time to time, and the way Windows works it may mark a block as bad when it cannot read the block when it is not really bad. Especially if these drives move back and forth between different systems I would suggest from time to time that you remove the data off of the drive and simply reformat the drives that should limit that from happening and help to prevent that in the future.

bpwahlgren Posted July 20, 2009 Author Share Posted July 20, 2009 Thanks Ram Guy that answered the first part of my question. Will running bad blocks on a flash drive shorten the life of the drive? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted July 20, 2009 Corsair Employee Share Posted July 20, 2009 It should not unless the drive it self is just failing, in other words its not uncommon to see a block or two fail over the course of its lifetime, but you would not notice it in most cases as it would use spars it has saved, but if the drive starts to fail it will eventually run out of spares and start showing less and less available.
