Things To Try & Things To Avoid

For Firmware Faults

Things To Try…

Seagate LogoSince Seagate’s problems with the buggy firmware on their 7200.11, 7200.12, ES.2 and (Maxtor) DiamondMax 22 hard disk drives, they have made several patches available to download online.

I haven’t used any of them so advise you to proceed with caution.

Early fixes for these firmware problems also erased the data on the hard drives – not much use if you valued your data !! – but later versions worked without erasing the data. Be careful if you are planning to use any firmware rewriting software – and make sure you know what it is going to do to your data before you run it on your hard drive.

Most data recovery companies don’t run these programs – Seagate were quite slow in developing a fix for this problem and in the meantime many recovery companies developed their own methods and techniques. Any data recovery company worth their salt will be able to recover any of these drives without deleting the data held on them.

Seagate SCSI Drives

Seagate SCSI hard disk driveSeagate SCSI drives will sometimes fail and show the following symptoms

  • When powering up the message “Medium Error” will be displayed
  • The drive will be detected as either ‘0 Bytes’ or ‘-1 Bytes’

This is a far less common problem and is recoverable by only a handful of data recovery companies in the UK.

Things To Avoid…

Remember a firmware fault means there’s an error with the program that runs your hard drive. So there’s no point

  • Running any type of data recovery software on it. You need software that reprograms the firmware. Once you’ve done that, access to your data will be restored.
  • Changing power and data cables
  • Swapping controller boards
  • Trying spare parts
  • Trying the hard disk in another machine

So to summarise, you can either (a) take your chances with a piece of software off the internet (if you are going to go down this route I recommend you ALWAYS get it from the manufacturer’s site), or (b) use a data recovery company (the good one’s will have performed this procedure many times before)
