Install western digitial 640gb WD6400BEVT firmware

[LochyMacleod]

Long story short, i wanted to use my spare hdd for my xbox so i flashed it so the xbox would regonise it, so now it thinks its a hitachi 240gb

I want to re install the firmware back to its original state.


any ideas where to get it and how to reinstall it

Thanks Lochy

Assuming you used HDDHackr, then use your UNDO.BIN file to restore your drive to its original state.

If you've lost your UNDO.BIN, then don't be tempted to use one from another drive. You will probably brick your drive if you do. Instead there are ways to recreate the UNDO.BIN from information in the reserved System Area on the drive, but you will need to do a bit of work in DOS. I can help you with this.

Thank you, i have lost my undo.bin.

I would appreciate the help.

I feel this could take a while, as we are on different time zones, so if u want you can post as much as you can for me to do and i will just go ahead and do it

Before we start examining the firmware, you may like to try some simpler things.

The first is to attempt to restore the drive's original factory capacity.

One way to do this is to use the NHPA command in MHDD. The RHPA command displays the factory capacity.

Use version 4.5 of MHDD. It incorporates ATA command scripting whereas v4.6 does not.

http://hddguru.com/software/2005.10.02-MHDD/

You will need to configure your SATA controller in BIOS for legacy or IDE compatibility mode. This will make your SATA drive look like PATA. MHDD expects to see your drive as the master on the secondary IDE port.

If your WD6400BEVT reports 250GB as its factory capacity, then this will be because HDDHackr has altered the drive's firmware. In this case the NHPA command will leave the capacity unchanged at 250GB.

The next thing to try is to edit the Hitachi HDDSS.BIN file. The header of this file contains Hitachi's firmware version, serial number, model number, and total capacity in LBAs. We will need to replace these data with WD's parameters.

The following article is my attempt to understand how HDDHackr works:

Here is the HDDSS.BIN file for a Hitachi 250GB drive:

This is the section we need to modify:

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000050  FC 17 2C 17 7A D4 F8 D6 70 59 1C 1D .. .. .. ..

You need to replace the text strings as follows:

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000050  FC 17 2C 17 7A D4 F8 D6 B0 82 85 4A .. .. .. ..

You could use a freeware hex editor such as HxD:
http://mh-nexus.de/en/hxd

The 4 bytes at offsets 58 - 5B are the total capacity of your WD drive in LBAs. This will be printed on the label, 1250263728. You then need to convert this number into hexadecimal format. Google's calculator can do this for you:

http://www.google.com/search?q=1250263728+in+hex

The result is ...

1 250 263 728 = 0x4A8582B0

Now take the hexadecimal value and reverse the byte order so that the number is in "little endian" format, ie ...

B0 82 85 4A

Then enter the above numbers at offsets 58 - 5B.

Now use HDDHackr to apply the modified HDDSS.BIN to your drive. If this doesn't work (HDDHackr may complain that your WD drive is too small), then we will need to use MHDD to read the original firmware information from the drive's firmware zone. For this you will need to boot MHDD from a writeable medium such as a floppy drive or USB flash drive. The latter will require you to enable legacy USB support in BIOS.

I'll explain the procedure in my next post, if you get to this point.

Thanks, it worked using the hex editor it now shows all 600GB.

Very much appreciated
