: I need a bios upgrade for my thinkpad 350. I have a 5 Gig hard drive in it but it only accounts for 82 Mb of it. Any help or advice would be thoroughly appreciated.


Suggest that you search IBM's web site and check with their Tech Support - they may have an update that is not posted. BUT there may not be an update available.

If you cannot find a free BIOS update from IBM one choice is a custom BIOS update (expensive) from Unicore at:
http://www.unicore.com

The inexpensive ("free") solution is to use a drive overlay program. IBM posts "Disk Manager" on their web site for this purpose. Before you jump at this "solution" beware that there potential pitfalls and you should read about some of the drive overlay difficulties at:
http://www.wdc.com/support/faqs/software/ezdrive.asp#lba [FAQ 29, 30 & on]
and:
http://www.maxtor.com/Maxtorhome.htm [Select Product Support, Desktop (ATA) Drives then Technical Procedures] [Docs 24003, 24006, 24019, 24020, possibly others]
and:
http://www.seagate.com/support/kb/disc/dm71x-lba.html [Migrate from DM to LBA]

Briefly, you are likely to have problems if the drive overlay is not compatible with your PC (low likelihood, but an earlier DM version may suit better), trying to operate DM on a PC that has more than one drive maker and/or model and when trying to recover data from your HDD using a desktop PC (when your laptop fails) - usually you can see the desktop HDD or the laptop HDD but NOT BOTH at the same time; makes data recovery a bit tougher even if the laptop HDD is working.

If you elect to use the drive overlay (basically as a last resort) you will need to design and USE a robust file backup system so that you minimize the need to recover files when the laptop fails. Seems like this would be a good idea even if you don't use DM. Note that you don't need to backup system and program files - they can be recreated/reloaded from the CDs - you only need to backup the things you want to keep such as downloads, documents you wrote, picture files you adjusted and so on. If it is already on CD you don't need to put it on another CD (Backup to CD if you can).

Hope this helps,
Henry
