External Hard-drive being detected but not displayed

I have a Samsung Spinpoint F1, Model: HD103UJ, 1TB 7200rpm HDD that is housed in an external USB 2.0 enclosure (Integral Black aluminimum- i don't know the model number for it)

It has worked fine for over 8 months with no problems within Windows XP Pro. Yesterday i decided to backup some work on my MacBook Pro using OSX Leopard'sTime Machine utility and plugged in the hard-drive. Time Machine explained the drive would need to be formatted in order to do the backup, to which i clicked 'Cancel'.

So using finder i tried to just drag my work onto teh hard-drive instead of using Time-Machine but PSX wouldn't let me do it this way either. So i backed up my stuff on anotehr drive altogether.

But since then whenever i put the Harddrive into my PC (WinXp Pro) i hear the USB chime and the remove USB device icon states "Safely remove USB device" but doesn't show a drive letter. The drive is also not showing in My Computer or Disk Management. I have checked Logical Disk Manager via MMC and that is set to Auto and is started.

I ran a diagnostic tool from Samsungs site called Hutil 210.exe which did absolutely nothing. I have tried using a different USB cable and USB port but still no joy.

I'm about to try installing the drive directly into the PC to see if thats the problem and ill post back results.

Formatting is not an option as data is valuable. I'm stuck and don't know what else to try.

Any help appreciated

I have tried to access the disk in Vista (I have dual boot config) and Vista seems to detect the disk in the disk management console  as "Disk 5" Status Unknown - Not Initialized. I'm scared to initialise the disk as i don't know if it will wipe my disk. I can choose MBR (master boot record) or GPT (GUI Partition Table) i don't know which to choose... help

I have now tried to initialize the disk via Vista disk management console. Regardless of which mode i try Windows reports "the device is not ready".

I don't know how else to entice it... i have tried chocolates and fine wines but still the device is not ready...

I presume it found no errors in the disk.  Or what did it do?

No.  Do NOT do this.

>> Chkdsk?
No.  Do NOT do this.

Get GetDataBack http://www.runtime.org/  Free to try.  If it sees the missing files you pay for full functionality.  All you are going to do is use the free version of GetDataBack and see what files it can find on your disk.

It is probable that there has been corruption of some sort in the partition or file structure.  Report back what GetDataBack can see so a strategy can be determined.

dbrunton,

This is a great suggestion, and I highly promote your suggestion, but why would you say that he shouldn't schedule a chkdsk?

chkdsk might do a repair.  There's no guarantee that a chkdsk repair will fix the problem.  It might make the situation worse.

In situations where data recovery is important I believe in recovering data before trying to fix the problem.  Fixing the problem may work but it may also make the situation worse.

Very true, and I have also said the same thing to others, dbrunton.  Very good point.

Not necessarily.  It's not showing in Disk Management and you are getting the "the device is not ready" message.

This could be a number of reasons.  Faulty USB enclosure.  Insufficient power to the USB enclosure.  Bad connection to the enclosure.

I'd recommend taking this drive out of the enclosure and directly connecting it to the motherboard.  It's SATA so make sure any motherboard you connect it to has SATA and preferable SATA 2.

Why do you keep typing "teh"?

Load up some sort of Live CD and see if the drive shows then.  I suggest Knoppix.
