i dont know if the problem is windows 7, i have deleted the partition formated it too NTFS but it wont recognise the lost space it says 31.4gig and should be 160 gig drive. ive used that tool fat32 formatter, ease us partiton manager, Partition Wizard Professional 8.1 and even windows 7 disk management & none of them see the lost space or unallocated space & only the drive with 31.4 gig. im either not doing the format correct or these cant bring back the drive. i would appreciate any ideas on this windows 7 problem
