Where has the HDD been sitting for 2 months?

by OldER Mycroft In reply to Retrieving Files from a C ...

Since you are referring to the HDD as a separate entity (not part of a computer system) I'm assuming this HDD has been sitting alone for a 2 month period.

If it has, are you aware of what conditions it's been in, any rough treatment, excess heat, excess damp, physical trauma? Has it been sitting near, or on top of a loudspeaker?

There's not much point applying software cures to a possible hardware disaster.

OH the good old Death Stars the only bad IBM Product ever made

Now provided that the drive hasn't suffered any Physical damage or abuse I'm assuming that it's an Internal HDD as you said that BIOS Couldn't see it and if it was in a USB Caddy/Enclosure BIOS couldn't see it unless you can boot off USB Devices and even then it's a marginal Call for BIOS to recognize a external HDD connected through USB.

If it is a IDE Drive is the jumper set correctly for the computer you have fitted it to? If it is a SATA Drive can the computer you are using it in actually see other SATA Drives in BIOS and does it need a SATA Driver to be usable in your OS?

Have you looked in Drive Manager to see if it is present there if you are running some form of Windows?

If you just want to know how to recover data off this drive it depends on how important the data is if it is ultra Important send the Drive to a Data Recovery House unless it is one of the old Glass Platter Drives and makes a funny rattling sound when you shake it. If that is the case the Platters have been smashed and there is no chance of recovering anything off the drive with the possible exception of severely cut fingers if you are silly enough to actually open it up.

But if it's not making any funny noises when you shake it without power applied a Good Data Recovery House will be able to recover something off the drive. On Track managed to recover 90% off a HDD that was on Colombia so that the experiment it was monitoring didn't need to be repeated at the cost of Millions of $ in space. But by the same token 2 other drives from the same Space Shuttle proved unrecordable in any form they had just been subject to too much heat as the space craft disintegrated.

If you just want a software solution here is a list of some of the more commonly used products but you need to know that the HDD hasn't been subject to any abuse before you spend your money otherwise it will just be throwing good money after bad.














While the last 2 are from the same company they are very different products. Win Hex should only be considered for use by someone who knows Hex Inside Out while Davory is a great cheap General Purpose Application.

Personally I prefer the On Track Option but it's anything but cheap. However because I use this type of software a lot it's paid for itself many times over by now, for a cheaper option Spin Rite from Gibson Research or Stella have both very good reputations by other TR members.
