Hi Guys,

Could someone please post firmware for HUA722020ALA330 .

Thanks alot

First of all, why?

What makes you think it's a firmware problem?

What do you plan on doing with it? Do you have a tool such as PC3000 to work with the firmware?

It would help if you stated the symptoms of the issue.

Sorry for the questions if you're a "pro" and have diagnosed the problem properly and need to fix a firmware module, but if that's the case you would have surely stated the version of the firmware you need and the ID of the damaged module(s).

Either way, good luck!

New!! HDD-PCB.COM for all your PCB and donor HDD requirements!

I recently got a bunch of drives that have a factory label showing HUA722020ALA330 2TB but SMART report shows 1TB capacity and firmware version that belongs to HUA722010ALA330 1TB and the drive capacity is shown as of 1TB.
The PCB also looks like it is from 2TB drive.

So it looks to me like someone flashed 2TB drives with 1TB firmware. Don't ask me why but I don't see any other possibility.

So I would like to try flashing one of these drives back to 2TB.

I'm not a pro and I don't have the PC3000.
I assumed that like most drives the firmware can be simply flashed with software utility rather than specialized hardware.


Thank you.

Unfortunately it's not as simple as that

It could be something as simple as a HPA cut, in which case some free software like HDAT2 or MHDD could reset the HPA.

If you wanna send one to me, I'll take a look and if it's a simple HPA reset then I'll do it for free

In short
Either its HPA or it has been made for a reason
If its HPA you can do it without special tools if its been made for a reason (bad zones for example) Its not gonna help you (p-list or bad head...)

Thanks pcimage for an offer to help.

I have twenty of these drives.

If this is HPA then why the firmware shows wrong version (from 1TB drive)
All the 20 drives work great in a RAID array as 1TB drives and SMART shows no reallocated sectors.

I just tried swapping a PCB from a known good 2TB drive and after the swap the drive came online under windows system tools but would not format or write and the reported capacity was still only 1TB.

PCB swap will not help, the firmware isn't there. In addition, each and every PCB is absolutely unique to each drive, with unique data in the NVRAM.

Do you think that flashing the firmware would give us more clues and if so then can you post the firmware and a utility to flash it.

The one problem that may occur is that a flashing utility will not flash it with 2TB firmware from HUA722020 because the drive will report itself as 1TB HUA722010.

I have flashed many Seagate drives but never a Hitachi.

"Flashing" firmware is only for minor firmware updates or "bug fixes" (e.g. Seagate SD15 to SD1A) on a working drive and are factory released specific updates, using specially written code specifically for that sole purpose.

You cannot simply "Flash" another firmware to a drive, there is SO much drive specific data in the firmware.

Perhaps this might help explain better...

If this is the case then how the heck 1TB firmware got onto a 2TB drive. If someone was able to do it then someone can undo it

Hi all,

I've also got a refurbished HUA722020ALA330 (2TB) labeled disk, which appears as HUA722010ZLA330 (1TB) in Linux and Windows.

Did anyone find out what happened to these devices? I think it's done during the refurbishing.

Thanks for your help,

Mathias

Hi all,

I have also few of these drives available, and I would love them to become 2 TB drives, not just 1 TB. I can perform some tests or something, but I would like to know where to start. Thanks in advance.

the Answer is more simple. This disk were ment to be in a 3par array for a 1TB strip (not raid)of chunklets. The manufacturer, Hitachi in this case was short of 1TB HDD and they used 2TB with one 1TB controller to replace it.
