While trying to install PATA 250GB HD (XP Pro) only 130GB recognized. Upgraded BIOS to v1.4 (latest) and assured by Toshiba that this would enable computer to handle 250GB. No such luck. Accessed BIOS (esc,power on, F1) but limited functionality. How do I access more functional BIOS Maintanance to check settings to see if change needed for 250GB HD and/or how do I get current configuration to accept 250GB?
According to the detailed specs on that model, it came with a 60GB ATA-5 EIDI hard drive. therefore, you can use any ATA compatible (ATA-5, ATA-6 or ATA-100) EIDE/IDE drive that has jumpers enabling you to configure the drive as "Master". Western Digital Blue Scorpio and Seagate Momentus lines both have models that will fit the bill. You can find those drives at your neighborhood BestBuy or Staples pretty easily. I don't know if the A25 BIOS supports 48-bit logical block addressing (LBA), in spite of what toshiba says, If it only supports 24-bit LBA the maximum drive size is 137GB. If it supports 48-bit LBA then you can go as high as you can find drives available; usually 500GB. I suspect that it supports 48-bit LBA because various online vendors list up to 250GB drives for that model. The most important thing about the drive, though, is that it MUST be jumperable as 'master'. A cable select only drive won't work. Both the Western Digital and Seagate EIDE models have jumpers.
