Used MBRwork utility to format an IBM 61GB deskstar HDD. Probably also altered EMBR to zero at same time, (was trying to remove a conflicting o/s). Now see only 32 GB of 61GB capacity. Tried NTFS, FAT32, Partition Magic etc. Is there an IBM equivalent too to Seagate Disk Wizard. Otherwise any suggestions please ?
Agree mbrwork does list formatting as such but when all fails setting the MBR to zero does result in a clean HDD. (my problem - a little knowledge is a dangerous thing) Still how do I recover the missing 31 GB?
Yes, Peter, tried fdisk, that also shows only the 31 GB. When working with a Seagate HDD, have found the Diskwizard too very useful, but this does nothing for an IBM drive, and was hoping somebody could provide a pointer to a suitable IBM tool/utility. Thanks Bob 17
Don't know if this will work in your case but worked in mine insert W98 or WME floppy in and boot up on the prompt choose without CD Rom support on the A:\ PROMPT type FDISK then choose delete none dos partition delete the Prime DOS partition if your running W98 or WME then you will have to create a DOS partition then make it active then format if your running W2000 or WXP then all you do is insert the OS disks and this will partition and format for you. *****ALL DATA WILL BE LOST*****
IBM drives are now owned and supported by Hitachi - support/downloads page here. click here
I suggest you look at the drive fitness tests to see if you can reset your drive to "as was" status. I think zeroing the mbr will make it look odd - there should be information in the mbr relating to the partions.
If your drive is limited to 32Gb - this may be by your system - some BIOSs have this limitation - it could be that you had software installed on the drve to "fool" the BIOS. The On-track disk manager can do this - but I would stay well away from a version as old as 1994 personally.
Unfortunately Hitachi no longer seem to supply software to resolve this capacity issue (whereas Seagate and Maxtor do.) You could buy the current version of On-track click here
Hope some of this points you in a useful direction.
Tried this as suggested. Used the Utilities to set the MBR to zeros and then also the disk. Result is still only 32,247.6GB visible. Tried both Fdisk and Partition Magic to see if they would show the missing portion - no luck. Is there something earlier, such as the EMBR which has details of the HDD model with its capacity that I have corrupted ?
