Daniel Robbins President/CEO, Gentoo Technologies, Inc. o 'vraj' probleme s ext3 na notebookoch:
I discovered that the disk corruption problems that people were experiencing had nothing to do with ext3 itself, but were being caused by certain laptop hard drives. Unfortunately, certain laptop hard drives now on the market have the dubious feature of ignoring any official ATA request to flush their write cache to disk. This isn't a wonderful design feature, although it has been allowed by the ATA spec up until recently. With these types of drives, there's no way for the kernel to guarantee that a particular block has actually been recorded to the disk platters. Although this sounds like a thorny problem, this particular issue by itself is probably not the cause of the data corruption problems that people have been experiencing. However, it gets worse. Some modern laptop hard drives have an even nastier habit of throwing away their write cache whenever the system is rebooted or suspended. Obviously, if a hard drive has both of these problems, it's going to regularly corrupt data, and there's nothing that Linux can do to prevent it from doing so.http://www-128.ibm.com/developerworks/library/l-fs8.html
