Mit speziellen Tools sollen aber die Einstellungen der einzelnen Platten auch regulierbar sein.
:mrgreen: Aber natürlich, alles ist "regulierbar". Im folgenden auch zwei lustige Dingens aus "hdparm". Wobei sich die ganzen Antiviren-Freaks mal bewusst sein sollten, dass sich per Software die Platte raufdrehen lassen kann oder bad sectors geschrieben werden können. Die Software steht schon in hdparm als open source bereit. Fehlt nur noch der "Kollege", der sie missbraucht.
NAME
hdparm - get/set SATA/IDE device parameters
SYNOPSIS
hdparm [options] [device ...]
DESCRIPTION
hdparm provides a command line interface to various kernel interfaces supported by the Linux SATA/PATA/SAS "libata" subsystem and the older IDE driver subsystem. Many newer (2008 and later) USB drive
enclosures now also support "SAT" (SCSI-ATA Command Translation) and therefore may also work with hdparm. E.g. recent WD "Passport" models and recent NexStar-3 enclosures. Some options may work correctly only with the latest kernels.
[COLOR= #FF4000]--dco-restore[/COLOR]
[COLOR= #0000FF] Reset all drive settings, features, and accessible capacities back to factory defaults and full capabilities. This command will fail if DCO is frozen/locked, or if a -Np maximum size restriction has[/COLOR]
also been set. This is EXTREMELY DANGEROUS and will very likely cause massive loss of data. DO NOT USE THIS COMMAND.
[COLOR= #FF4000]--make-bad-sector[/COLOR]
[COLOR= #0000FF]Deliberately create a bad sector (aka. "media error") on the disk. EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! This can be useful for testing of device/RAID error recovery mechanisms. The[/COLOR]
sector number is given as a (base10) parameter after the option. Depending on the device, hdparm will choose one of two possible ATA commands for corrupting the sector. The WRITE_LONG works on most
drives, but only up to the 28-bit sector boundary. Some very recent drives (2008) may support the new WRITE_UNCORRECTABLE_EXT command, which works for any LBA48 sector. If available, hdparm will
use that in preference to WRITE_LONG. The WRITE_UNCORRECTABLE_EXT command itself presents a choice of how the new bad sector should behave. By default, it will look like any other bad sector, and
the drive may take some time to retry and fail on subsequent READs of the sector. However, if a single letter f is prepended immediately in front of the first digit of the sector number parameter,
then hdparm will issue a "flagged" WRITE_UNCORRECTABLE_EXT, which causes the drive to merely flag the sector as bad (rather than genuinely corrupt it), and subsequent READs of the sector will fail
immediately (rather than after several retries). Note also that the --repair-sector option can be used to restore (any) bad sectors when they are no longer needed, including sectors that were gen-
uinely bad (the drive will likely remap those to a fresh area on the media).
Mach dir also Gedanken von wegen Rot/Grün etc. und kaufe Dir was Du dir erwürfelst. Es spielt echt keine Rolle. Unter dem Strich ist der Controller genau der gleiche, und mit dem Rest werden sie keine grossen technischen Änderungen fahren. Sofern sich die Änderungen auswirken würden, könnte man dies nachlesen. Aber unter allen User-Berichten schneiden im Schnitt alle Platten gleich gut/schlecht ab. Schaue eher, dass Du nicht beide Platten (bei einem 2-Bay NAS) aus der gleichen Serie kriegst, das ist viel wichtiger. Hast Du eine schlechte Serie, kacken wohl beide Platten gleichzeitig ab.
