I currently working on hard disk and having some troubles conserning them. i got some machines which are lock on for certain types of hard disks and since they are no longer manufactured i must find a way through. So i had been looking for different ways in solving the problem.


The current software have been locked on the hard disk capacity and its name. I successfully found a way to edit the size of a hard disk through the DCO (Device configuration overlay) but i still can't find a wayto change the name of the hard disk. Any of you guys can help me to find a software which i can use to modify the name of the hard disk.

There is no free solution

If you want to do it yourself then there are at least three commercial tools
PC3000, HRT and Salvation Data Tools

Or you can find somebody with tools and pay him/her for the job

Have you tried the obvious alternative approach, ie have you looked for a "Maxtor something" text string in your software, and then attempted to edit that?

Do you have a chip reader/programmer that can read serial EEPROMs?

Just to save you on this effort
1. Fujitsu store model information on platters
2. Modifying ROM w/o recalculating CS is a very bad idea
3. Not all MHZs have external flash

1. If a drive PUIS (that's DR-speak for "Powers Up In Standby"), then any Identify Device report must use the data on the PCB. How does a drive identify itself in such cases?

2. I did not suggest that the OP modify the "ROM" without recalculating the CS (I assume "CS" is DR-speak for "checksum"). In fact there have been several threads where I have had to explain to data recovery professionals why a drive will not spin up if its CheckSum is bad.

3. I don't believe the OP is restricting his choice of replacement drives to a particular model. I suspect that he would be prepared to accept any drive that could be made to appear like a "Maxtor something".

It does not
Many drives in PUIS mode return almost empty ID sector

FYI PUIS is an acronym from ATA standard, so it's not DR-speak (neither the CS). Of course we can continue on this and pretend that WA is Australian-speak for Western Australia :)

Sure
Assuming that neither you nor topicstarter don't know how to do that finding programmer seems a little useless to me

Well, I'd have to see it before I could attempt it. If it's just a straight sum of bytes or words, then it shouldn't be too difficult. I know that some checksums (eg Samsung firmware) are byte-swapped, but that's easy to handle as well. If it's anything else, then I'll cross that bridge if and when I come to it. In any case, I should be offended by your assumption, but I'll let it go.

Model disk's names can be edited within the service area and the size of the hard disk CAN be edited by setting the Max LBA or CHS depending on the hard disk being used..
