HP 300 GB - 10000 RPM - WIDE ULTRA320 SCSI

[neuron]

Hi,

I have a 300 GB - 10000 RPM - WIDE ULTRA320 SCSI - HP MODEL:BD30088279 from a client.

The disk was underwater and lots of dirt in the PCB.

I remove the PCB and cleaned the contacts.

The PCB is naturally damage, because the computer was running when the water coming in.

Q. It's possible to change PCB and recover the data in this model and brand?

If not ... next step clean room.

Thanks in advance

I suppose that case should be a Seagate SCSI Chettah so most models has adaptive information inside , u should need to check that !

Thank you beto,

In small letters (right side of the label) we can read : ST3300007LC.

And your advice is ?

If the drive was fully submerged then there is almost no doubt contamination within the drive, as drives are not sealed 100%.


The preamp may also have taken damage if the drive was on when the water made contact.

you need original ROM for this drive, and there is water inside the drive if it was submerged, so don't power it up with new PCB or you will completely destroy surfaces of the drive

Hi,

So if the ROM is lost ... what is the procedure?

If ROM is lost you can throw it to a bucket
But damaged PCB doesn't always mean ROM is lost forever

And in this drive which 8 legs circuit?

Thanks

I must ask this: why do you gamble so much with your clients information, when you have such lack of knowledge in DR?

Upload a detailed photo.

Generally, 8-pin ICs that are situated near coils are MOSFETs, or FETKYs, or PWM controllers, ie parts of a switchmode DC-DC converter.

An EEPROM will have traces connecting to the MCU.

I'm simple followed your steps and procedure:

Not all procedures work on all drives. Each problem is unique to each drive and you need to understand what is your problem on this one before fixing it.

have u even checked inside of drive?

Do not think so on this one. He is more than likey an IT repair shop which a person has asked him to fix their drive. I really do not think he does DR work and that is why he is here searching for answers on this one. I think that he should find a good DR repair shop near to him and give this drive to them to fix it. Or to take a look at it. He is gambling with the data on this drive and some of the help he is getting from certain people is not good advice in this case. If he admits to following procedures on another post from 2007 this shows he is lost and searching for answers on this one.

In a SCSI Chettah the most cases wich i had check are working over parallell ROM there are few cases using Serial , ROM but the most wich i get here are over parallel , but like another guys told u, its very important check media , even SCSI Chettah has some tendence to head crash in a normal enviroment, so its very important check that in a Clean Room, but SCSI disks are more complex than IDE disks, not only by protocol´s used, Engineering its different too, so if u dont have experience, contact with a professional DR company

Thanks for your comments.

When I return to office, ... open and inspect.
