Linux will do this fine but it wears on the south bridge mainly and the disk secondarily. Typically the disk is the sturdier of the two. Assuming you unmounted it first, your may get anywhere from 20 to 300+ successful removals depending on the sb chip ie how much abuse it can endure. Then you start getting disk errors that are initially recovered but eventually hang your box. The south bridge ide channel and possibly the disk too, will be hosed. > > - > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ > - ----------------------------------------------------------------- John Heil South Coast Software Custom systems software for UNIX and IBM MVS mainframes 1-714-774-6952 johnhscs@sc-software.com http://www.sc-software.com ----------------------------------------------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
