Anonymous users2024-02-01Because a track cannot accommodate n=6, it will format a bad crc and use a floppy drive to write data near the index hole correctly, so hardware copy tools such as copy cards cannot copy it, but if you still want to read the track, the disk will index the number of holes by the way.

If it is still under warranty, you can go to the after-sales maintenance point to detect and replace, generally 1-3 work, if there is goods on site, it can be replaced immediately. Good luck.

You boot up, press F1 to enter the BIOS, press F9, select Yes, press F10 to save the settings, exit and restore the BIOS default settings.
If this still doesn't work, you'll need to send it to a service station to have your motherboard repaired.

May I ask which model of yours is E420?,E420 is generally installed with a pre-installed genuine system,There is a Q disk in the computer above the computer,It is the backup of the system,So you don't need to back it up at all,As long as the Q disk is not destroyed,When you boot up,Press F11,Press the above prompts,You can restore to the previous home version。 Actually,There's no need to upgrade the computer to the flagship version.,You can't use more functions in it at all.,The computer is enough.,There's no need to chase the best system.,I'm using the home version.,I have my own key.,But I haven't upgraded.,You can enter the key in the windows anytime upgrade in the control panel to upgrade,Computer,Just use it.,The flagship version of the home version is the same! Hope it helps!
i5-3230M GT740M 2G Graphics Card This graphics card is between GT640 and GT650 and can play 90% of the games on the market.
The game can definitely run, but the current ThinkPad is not good in terms of hardware or software, and a Little Red Riding Hood is my favorite.
ThinkPad E420, as long as 4000 or so, I'm using it, i3 processor, two G memory, the focus is on one G independent display, enough for study and work, and strong for games. As for the graphics processing power, all the game masterpieces are stress-free (of course, you are not asked to turn on full special effects, and some games have tens of thousands of machines with full special effects) Isn't Crysis 2 smooth enough? The built-in R&R backup is also very strong, ensuring the stability of the system, and overall, it is very cost-effective.
You're talking about the model of the graphics card.,Please make it clear.,It's completely usable in the XP system.,The current graphics card is very powerful.,Play with the special effects of win7 is no problem.。 >>>More
