Advanced Troubleshooting - IBM Deskstar 25GP Installation And Reference Manual

If the drive does not spin up, ensure the jumpers and cables are connected correctly. If
they are connected correctly, skip to the Advanced Troubleshooting section.
2. If the drive spins, does the BIOS see the drive?
HINT: With Autodetection selected, your BIOS displays the recognized capacity of your hard drive.
If the BIOS does not see the drive, ensure the BIOS is set to Autodetect and ATA/IDE
ports are enabled. If they are set correctly, skip to the Advanced Troubleshooting section.
3. If the BIOS sees the drive, does Fdisk recognize the drive?
HINT: Fdisk is a utility used to partition and format hard disk drives. The Fdisk program can be
found on your operating system startup diskette or in the operating system directory on your C:
drive. Use option 4 to Display the active partition or option 5 to select a different drive if the
system has more than one drive.
If Fdisk does not see the drive, skip to the Advanced Troubleshooting section.
4. If Fdisk sees the drive, does it see the full capacity?
HINT: Option 4 in Fdisk displays the drive capacity and partition sizes.
If Fdisk does not see the drive's full capacity, IBM DriveGuide may be required to
partition and format the drive. Refer to the section of this manual entitled IBM
DriveGuide Easy Installation Software.
Note: The Fdisk function shipped with Windows 95 and Windows 98 contains a bug which causes
the DTLA-307075 drive to be reported with a maximum capacity of 7768 MB. This is only a
display error and does not affect correct operation of, or access to, the full capacity of the drive.
Contact Microsoft for more information.
5. If Fdisk sees the full capacity, partition and format the drive.
WARNING: Partitioning and formatting will destroy data. If the data on the drive must be
recovered, call the IBM Hard Disk Drive Technical Support Center.
