Hi All, I need some advice on finding a solution to this problem . I have a hard disk mounted on a mobile robot. I am using ext3 fs. The hard disk is subjected to several bumps as the robot travels. I am experiencing frequent hard disk failure ( about once a month). I have thought about 2 different solutions to this problem. I would appreciate any tips on evaluating them 1) Use Compact Flash cards: This is a an easy solution. However, I need about 1GB of space. 1GB CF cards cost about $300. There is the issue of CF wear. The cost is the major con of this approach. 2) Using Ram disk. * Create 1 or 2 ram disks on boot. * Mount the stuff that gets written ( /var/log, /tmp, some /etc related to ssh) on the ram disk. ) * Put the hard drive to sleep, while the robot is in motion. * Sync the logs from the ram disk to the hard drive, when the robot is stationary. Approach 2 assumes that, if the hard drive is sleeping while in motion, it will not be damaged. Is this true ?? Does approach 2 sound reasonable? Any other tips/suggestions/criticism Thanks!
