I have an Toshiba Satellite M40 laptop that has a Fujitsu MHU2100AT ATA Disk drive. I've had two instances of major disk corruption and have brought the laptop back to Toshiba twice. The first time they found a problem in the power supply, but the second they said it was fine. I have windows installed on another partition and have had no corruption problems there since the first repair. I've also run spinwrite-6.0 on the disk and again it reports no problems. Here are some symptoms of the problems under Linux: I restore from dump backups after running mkfs on the Linux partition. During the restore I get some complaints of read/write errors (fortunately all in nonessential files). After the restore is completed, the system seems to be fine, however, after powering down an rebooting, major disk problems are found, and after running fsck, I end up with significant data loss. I've run with and without journaling turned on, but this doesn't seem to make a difference. I notice from hdparm that disk write caching is turned on. Any chance that there is a problem with the cache not being flushed before powering down? I'm running Linux-2.6.15.5 on what is otherwise a slackware-10.2 install.
