No terminal access after getting ready on ES.2

[bvreddy]

I have similar 4 hdds. Series is ES.2 , ST3250310NS. Firmware HPG2. Two are in good condition and remaining 2 are not detecting and similar symtoms. Both hdds are permanently busy and no access to terminal, but displayed 2 lines of info.
LED:000000CC FAddr:0024BF31
LED:000000CC FAddr:0024BF31
If I isolate the motor then its getting ready but no terminal access, and its detected as pcb defaults i.e
Model : ST_M13FQBL
Serial : QNR_BFW
Firmware : 11291209
Capacity : 3.86 GB (8 089 950)

Tried read channel short, then no terminal access and no ready. Customer told that he has seen smart bad status before crash.
Any help is welcome

Connect PCB alone and open HT, power on from ur UDMA and keep pressing Ctrl-Z in HT
it SHOULD work

then stop motor n connect pcb then power motor UP again n clear smart & G
then it should work after

this is normal Seagate issue

As it was discussed in earlier posts , terminal access is blocked in thease HP** FIRMWARE hdds . i noticed that Terminal access is available in similar working hdd.
It is having peculiarities and normal procedure (F3 Arch) is not working .
In this case i tried to update firmware
I downloaded the firmware update from Seagate web site and tried to update this drive
1. Disconnected pcb from hdd, connected to normal SATA port on motherboard and switch on
2. It is not detected correct values but it has given some default values ,so its ready now.
3. Pcb fixed on hdd while power is on
4. When i run the firmware update cd then the utility reports "Not found the model ST3250310NS" and exits.
Welcome any suggestions
