Has anyone run into the latest Advanced Format Drives? Apparently they're switching sector size from 512byte to 4Kb. Part of this means the boot sector will no longer be 63, since that doesn't align with the 4k sectors.
What's the impact to EEPC?
Documentation we received from HP indicates that only some drives will do the emulation, and users wil have to "align" the partitions with the sector breaks in order for them to work properly. Depends on the OS. (XP is not aware, Win7 is)
Very true - "native" 4k drives are not supported in the current product set (neither EEPC or EEFF), only drives which do the 512b emulation. The "alignment" issue does not affect supportability, only performance though.
The "awareness" of Vista and 7 is simply that by default they create the first partition at 2048, rather than 63 to give you logical>physical alignment.
SafeBoot, can you please clarify on the following scenarios?
We have some new machines that just arrived from Dell, and I'm still awaiting info from the specific site. It is unclear which type drive is used, but the Tier 1 support mentioned that on a fresh load with EEPC 5.x installed, the machine fails to complete the transition from EEPC logon to Windows loading. From what I'm reading here, it shouldn't matter, but Dell states that without alignment, some machines might not even boot, and warns that you should not align them with any tools until they have been decrypted.on 4/27/11 1:12:24 PM EDT
You should not align with encryption active, but otherwise I cant see any problems. There are bios bugs with dell 68xx etc and seagate drives though, so you might have to use achi mode until Dell resolve.
Thanks. We plan to align them with diskpart commandline prior to OS load, just to make sure no possibility of anyone aligning them post-EEPC install. Currently we are working on 6420 and 6520, but will make a note about the 68xx series.
