i've got a wd7500bpvx-60jc3t0 that i recovered data from for a friend a couple years ago and held on to afterwards. as a learning experience, and to have a spare drive to use for unimportant things, i was hoping to refurbish it. this drive appears to be one of the newer 'zephyr' series drives, and as such, the 0028 module (containing self-scan script) was wiped at the factory. any attempts to initiate a self-scan terminate within a minute or two due to this.
according to a surface scan using hd tune pro, the drive has a bunch of bad sectors in the beginning of the disk, but is good from there. i was hoping to either rebuild p-list from the result of a self-scan, or "cut" the drive to a smaller capacity, bypassing the problem areas.
so far, i've tried writing a couple modified 0028 modules i found here that supposedly would work on zephyr drives. while they were written successfully, and i can view the new script sequence in WDR, the test still ends after only a couple minutes.
apparently, there are also some modification(s) necessary to the 0002 module to enable self-scan on the zephyr series. i found a before-and-after stock/modded 0002 module for another drive, and checking the differences between the two in hex format, there were a LOT of changes made, i.e. not a transformation i could complete using a hex editor.
my question is: does anyone know which modifications to 0002/0028 are necessary to have a successful self-scan on zephyr drives? i've uploaded the modules i pulled from the drive here:
https://app.box.com/v/wd7500bpvx-modules-7zthe only tools i have at my disposal are an old bios-based pc and a couple versions of wdr & trex. i have usb-ttl adapters, jtags, and flash programmers too, but i don't think those would be needed.
by the way, blindly following another post here suggesting to "format with p-list" seemed to wipe the p-list completely
i've tried a normal surface scan in wdr, but TONS of "defects" show up even after raising the bad block timeout threshold. fwiw, they do appear to be in the same region (per the p-list graph) as the original ones. except, there are no entire tracks listed. i believe i should have a backup of the p-list in the .7z of the modules i posted.
thanks for any insight!
