|I have seen a similar concern on several other threads, but so far not seen a solution ....|
I have an external hard drive (1TB), which has been partitioned some time ago - using Acronis Disk Director suite. The partition in question is labelled 'I' and is 120GB. I created this partition specifically to keep a mirror image back-up of my main internal C drive, which has a capacity of 110GB. The I drive had a previous image file (ie about 90GB) and a couple of folders with about 18GB of data in them.
I deleted the old image file in order to make a completely new one from the C drive, but Windows Explorer still shows only about 20GB of free space, not the 90GB or so I was expecting. The Recycle Bin is empty. I have closed down and rebooted. I have run 'chkdsk' at the command prompt for the I drive and, even in dos I get the same info regarding available space ie report shows 104GB of data in x thousand files - but only the correct total of data in the two named folders (ie the 18GB that I know about). I ran 'dir' on the drive, but it shows '0 files; 0 bytes' in the core directory. So where is the remaining 90GB lurking?
I have tried to format the I drive, using command prompt 'format i:' since I have made a back-up copy of the 18GB of data in my two 'known' folders so I don't mind losing it, but I get the 'enter current volume label' response and I haven't yet found a response that works - actually succeeded in re-labelling my C:/ drive to I:/ in the process, but thankfully that's now been rectified.
I'm using Windows XP as an operating system.
I can't think of anything else to do to make the cleared space available. I don't want to reformat the wholeof the partitioned external drive in question since there's stuff on the other partitions that I cannot afford to lose and I don't have available HDD space to move this data elsewhere.
Any ideas anyone?
