Hello everyone,
I have flash the firmware of my Maxtor disk; now the disc is recognized slowly at boot.
The firmware I downloaded from here:
http://files.hddguru.com/download/Firmw ... Y080M0.exe
These are the technical data of the disk:
Maxtor DiamodMax Plus9
80GB SATA/150 HDD
Interface: SATA DESKTOP
LBA: 160086528
Model: 6Y080M0
Code: YAR511W0 K,M,B,A
SN: Y26WV8HC
TLA: 6Y080M042731A
PCB code: U7FYA
301861101 SERIAL/CALYPSO/P11/THERM

"FLASH" what ? and WITH what ?
Hope there was no data on it because if you did not backup the original FW (on the platters, not on ROM) it's lost "FOREVER"...

"FWupdate_YAR51EW0_for_6Y080M0.exe" make a boot floppy that update the firmware.
The data on the disc are fully accessible; issue is just to boot, the drive is not recognized sometimes or it is recognized slowly.

If I succeed in finding this firmware YAR511W0 I manage to update it using the same software before.

The FW update program does not "FLASH" , do only update a section of the FW that is actually ON THE PLATTERS. Anyway if the disk is slow at boot or sometimes not recognised, the problem is elsewhere.
Backup data ASAP and replace drive or have it serviced - I can recertify it 100% like brand new but have to send it in.
Do not attempt risky operations if you did not backup DATA on drive.
