Compatible head stacks?

Will head stack swap?

Many people like to match MLC code also, but with this family of disks I match only the model and works 9 out of 10 times for me.

Hi,

maybe the MLC was matching 9 times out of 10, wasn't it

Next time I will check if MLC matches and let you know :wink:

Hi,

thanx, that will be informative.

For heads compatibility MLC not important.
Also for some even model matching not important.
MLC relates ROM & NVRAM versions.

Hi,

Sometimes I experienced problems when using heads from HDAs with different MLCs. After finding a matching one everything went fine.
But it is true that it is not absolutely neccessary to match, but better:)
I also used AVVA heads in AVV2, but it read quite slowly.

Today I had a clicking hitachi Deskstar which needs Head Stack replacement. I also have a donor but MLCs are different so I decided to swap heads anyway to see if you really dont need to match MLC.

Donor: Hitachi Deskstar IC35L060AVV207-0 61.4GB
P/N: 08K0833 MLC: H69206

Patient: Hitachi Deskstar IC35L060AVV207-0 41.1GB (refurbished as a 40GB)
P/N: 07N9218 MLC: H69404

Performed Head Swap and kept Patient PCB on Patient Disk. Recovered all the user data.

Hope that this is informative to everyone here

That's always nice to know for future cases.

Thanks
