Barracuda 7200.11 Reporting Wrong Cache Size

[Deshman]

Not sure if this is the correct area for this or if you've reported this already (apologies if you have) but apparently some revisions of the new 7200.11's are reporting completely incorrect cache sizes. I didn't notice but when I checked it out they were right. A mate's drives were even reporting 8mb only!

From the Seagate website:

Seagate has recently discovered that some of Seagate’s Barracuda 7200.11 hard drives with firmware version SD04 or SD14 will report an incorrect cache size.

The discrepancy is due to the firmware incorrectly identifying the cache size during the buffer size auto detection algorithm. This incorrect value will be passed from the drive, via the “Identify Drive” command to the system BIOS, which in turn reports the incorrect cache size.

The following Barracuda 7200.11 models have been impacted:

* ST3500320AS PN 9BX154-302 with firmware code SD04 or SD14

* ST3750330AS PN 9BX156-302 with firmware code SD04 or SD14

* ST31000340AS PN 9BX158-302 with firmware code SD04 or SD14

This software will create a floppy disk with a bootable DOS and the flash.bat file. To flash the firmware remove all SATA and PATA devices that are not the affected HDDs and set your BIOS to boot from the floppy, restart and wait. Press F10 to exit the DOS Help when it loads and type: flash.bat

When it is done it will show 'cycle power to continue', wait until you can hear your HDDs have stopped their activity then restart your PC and remove the floppy. Done
