Hi. I have two Seagate 3tb XT internal drives and a Hitachi drive used as my boot drive. The two xt drives were partitioned due to the 2.1tb limit using Seagate drive wizard and have been working fine. I decided to clean up my PC and re-install Windows 7. I re-installed to the Hitachi drive which went fine but now both xt drives are only showing the larger partitions and the smaller partitions are showing as unallocated in drive wizard and disc management. I cannot add a drive letter or revive the partitions without losing the data as the only options available are to format or wipe the partitions. Am i missing something obvious here? I can't see how both drives could have become damaged in the space of an hour and i definitely did not format or change anything except to the Hitachi drive. I'm not really familiar with partitioning drives but i really can't see what i'm doing wrong, i just expected to see all four drive letters as they were before the re-install.
Would really appreciate some help with this as its an awful lot of data i've lost. Thanks in advance
